Dual Monitor - Secondary Monitor Flashing Issues

Q: Dual Monitor - Secondary Monitor Flashing Issues

I recently purchased another monitor so I can run dual-monitors on my newly upgraded-to Windows 8 desktop. I set the monitor up last night, and I haven't had any major issues so far... One issue that I've run into, though, is the secondary monitor (regardless whether it's the monitor I owned first or the one I just bought) flashes randomly. Last night, a restart fixed the issue, so I didn't think anything of it. Today when I started it up, it was fine again for about 5-10 minutes. Then it began to flash randomly. It's not a constant steady flash, it only happens once every 3-10 minutes, but it shouldn't be happening. Does anyone else have the same problem and/or have suggestions on how to fix it?

Add'l info:

Monitors (both connected via HDMI, primary to primary gfx card, secondary to secondary gfx card)
1x Asus VW246H 24"
1x Asus VE248H 24"

Both set to 1920x1080p resolution, left as primary, right as secondary.

2x EVGA Nvidia GTX 560 Ti's in SLI Configuration

Most recent stable Nvidia drivers are installed. I'll test the beta ones later and update this if anything changes.

The Issue: Dual monitors, secondary stays in D-VID Power Saving Mode and goes to black and flashes the standby light.

Monitor Model: LG 24'' IPS LED D2343 (CINEMA 3D)

Was working perfectly less than 24 hours ago, upon boot up this issue arose, attempted fixes to follow:

Basic Fixes Attempted:

1. Classic restart.
2. Removed screen connections, power and DVI.
3. Swapped Ports on the actual GPU between main and secondary monitors, main monitor fires up no problem.
4. Used the Monitor and cables with a different PC- The Monitor worked perfectly.
5. Reinstalled GPU Drivers.
6. Cleaned out the tower, dust etc.
7. Checked and re-checked as many settings as possible on W10, everything from Power settings to Display and Device management, this includes trying hot keys- like those used to project screens etc.
8. Checked windows Update- fully updated.

I have just did a clean install of Windows 7 ultimate from XP and I am unable to get my dual monitors to work like they did in XP.

I have a DVI Radeon graphics card plugged into the agp slot, and a Nvidia geforce vga adapter plugged into a pci slot of my dell optiplex 755. When I am in the screen resolution settings the second monitor cannot be detected.

In bios I have 2 options under primary video adapter and they are auto, and onboard card. When set to auto the Nvidia card gets a signal but the Radeon does not. There are no conflicts in the device manager, and all of the drivers are up to date.

When I change the bios option to onboard card the Radeon adapter gets a signal but the other monitor cannot be detected and in device manager there is a yellow exclamation mark next to Standard VGA adapter and a code 10 error that states the device could not be started.

I have powered down, and unplugged every cable, I also tried to use the integrated VGA adapter to the Intel G31/G33/Q33/Q35 Graphics Controller but the computer will not even boot. I get
"System Halted
Attention Unsupported Video Configuration Detected"

I have two monitors, both work fine as standalones but Windows will not detect either as a secondary.

Please help me someone, I am so used to having my helpdesk email open in one monitor and all of my other work in the other monitor.

Try updating your card drivers. Go into Device Manager and right-click on your display adapter.

I suspect that the cards are too old, though. We will see.

I have a dual monitor setup, where the laptop is hooked to a 2nd monitor (TV) thru an HDMI . I primarily use the 2nd monitor. Can I blank screen the 1st (laptop screen) monitor, yet continue to use the 2nd monitor with the lid open for access to the keyboard?(I noticed with changed settings in Win7 control panel, I can close the lid without cutting off [sleep, hibernate or shut-off] the computer and had to reduce the 2nd monitor display to fit the visible screen. But to use the keyboard one has to open the laptop lid, which kicks in the 1st screen)Thank you

I am using a 22" screen for my primary screen and the laptop lid open for a secondary screen. The main screens resolution is 1680x1050, I can set it to anything I want and it's always using the full screen. The laptop screen on the other hand will only use the full screen if it's at 1400x1050 resolution (max for that screen, IBM Thinkpad T43). With the large 22" screen I have no trouble reading the screen at high resolutions, the screen is huge, with the little 14" screen though I have to strain to read the screen at 1400x1050.

The problem is when I set the laptop screen to anything lower than 1400x1050, it uses less of the screen. Preferrably I want it at 1280x1024 or 1024x768 (I dont know which I want yet as I can't see the freaking screen at that resolution). At 1280x1024 for instance the useable screen is just a box in the middle, so the "1280x1024" is still barely readable for me cause it's shrunk from full screen, plus it's just annoying only using a portion of the screen.

I have played with the ATI Control Center, the Thinkpad display settings and windows display settings and just cannot get this thing to go full screen at lower resolutions when docked and using the external monitor.

Anyway to resolve this?

Need help with dual monitor setup. First time trying to do it.

2 Problems
Second monitor does turn on, but is only showing native resolution (1024 x 768) but it has the ability to go up to 1280x1024.
I want to to be able to set it to 1280x1024.

Second monitor will not boot up along with computer.
I shut down my PC, the monitor is still plugged in, and it doesn't wake up automatically.
Things I've tried
- Updating drivers, obviously. (Nvidia, etc.)
- Uninstalling default driver of second monitor in Device Manager then rebooting computer, then plugging out and replugging the monitor back in (so it reinstalls) because it doesn't boot up on its own.
- My Power Options is set to "High Performance" so that's not the reason why my 2nd monitor isn't booting up with my PC.
- I have tried plugging in the VGA cord of my second monitor into the mother board but it didn't come up.
General Information
- The second monitor is an HP Compaq LE1711
- The second monitor is plugged into my GPU? via a VGA cord into an HDMI to VGA Pigtail Adapter (company: ATIVA), into an HDMI port.
- The main monitor (1920x1080) is plugged into my GPU?, via a VGA cord into VGA to DVI-I Dual Link Adapter, into a DVI-I port.

Picture of what I'm seeing:

I'm pretty sure I've got some of the terminology wrong (I'm not a computer expert).

Any help is appreciated!

I have two monitors hooked up, my primary is a 22 inch samsung my secondary is a 19 inch microtek. My problem is that some things (mainly firefox and Documents) open on my secondary monitor. Even if I move the window to my primary monitor maximize it and then close it, when I open it again it opens on my secondary. I really only use my secondary monitor for design work in photoshop, illustrator etc. so it is off a lot of the time. It is annoying to have to turn it on just to move firefox over to my primary one.

What would cause this problem and it only does it with some programs and windows, but not all

A:Dual Monitor Secondary Display

try this: minimize the window drag it to the appropriate monitor, and close it while still windowed.
Relaunch the program and it should appear windowed on the correct monitor. After maximizing and closing it again it should launch fullscreen, and in the correct monitor.

I think this is the right place to ask this.

I have two monitors connected to the ATI Radeon HD 2600 XT graphics card (it has two DVI connections). With both monitors on everything works fine. Windows remembers which apps I have open on which monitor and so on.

However, sometimes I turn on only one (the primary) monitor. In this case Windows somehow still thinks that both monitors are there, so the apps which would open on the second monitor still do so, i.e. I can't see them when I start them, and the mouse goes easily beyond the active monitor.

Now, the second monitor is completely off - it has a real power switch. But it's possible that it still has some voltage through the connector so that Windows - or the graphic card - detects its presence. I have not tried to unplug it but maybe I should do that as well.

So finally my question - is it possible to make Windows aware that the second monitor is not in use and only extend the desktop when the second monitor is on and do that without restart/log off?

Thanks for any suggestion.

A:Dual monitors, secondary monitor on/off intermittently

If it's plugged in when you boot, Windows will assume it's in use and available...

No known Windoze workaround... connect multiple monitors, Windoze will 'think' they're all turned on and working - however you might find some third party software (like Ultramon for example) might be able to correct the problem...

I recently moved my studio downstairs, and the only thing that has changed is that I now use a Wacom Intuos 6" x 11" tablet. When running Corel Painter 11 the right monitor is sluggish, but the other one is fine.

For example if I drag any painter window around on the right monitor it is really sluggish, but if I drag it to the left monitor it's fine.

Monitors on same ports as before, and I did not have this issue before I moved my studio.

Driving me crazy, and I need to get back to work! Any help, suggestions greatly appreciated!

Moving the rig around could have loosened a connection, or the video card itself. Check all connections, and reseat the video card.

i've got a minor issue where some apps choose to launch on the secondary screen, rather than my primary. i believe it is because my secondary is actually to the left of the primary (it is a TV that is physically to the left of me). is there a way to tell apps which screen to launch in? i'd rather have all my apps launch on the primary display.

A:dual-monitor: apps starting in secondary screen instead of primary

Vista goes screwy with this sometimes - but mostly, I have noticed, when I run WMC and it opens in the window that the app is in.

Try running WMC on your TV so that it forces the app to the other 'monitor' and then hit the start button on your KB, freeing your mouse from WMC, and then go to the other monitor and close the app(s). Then close WMC and see if the app opens back on the TV or in the monitor.

I have HP Desktop Tower Pavilion with windows 10, I had two HP S2031 monitors in dual mode, worked fine. One of them died, I got a good deal on a larger HP 27er monitor.  I hooked it up, they were both working fine ... it was using a default monitor
setting ... and then yesterday the computer downloaded some updates, and in doing so, it downloaded the driver for the HP 27er and installed.  The next thing that happens is the older HP S2031 starts to go dark ... like it is going into sleep mode, and
then it is totally black.  On reboot, it starts up with both monitors working, but within seconds of reboot the HP S2031 goes black again. The HP S2031's buttons do nothing, other than the power button, which turns it off and on, but that is it.  
I have done all troubleshooting, I did not even have them set up to sleep, all settings are at NEVER.  In coming here, I have done all the fixes I can find for similar  that are posted for similar issues, the Windows Key + W... nothing. 
The create new power plan ... nothing.  the device manger>display adapters>disable then enable ... nothing.  and lastly Start>Control Panel>System>Device Manager>display adapter>driver tap>update ... still nothing.  HOW
DO I GET THE HP S2031 MONITOR TO NOT BE IN SLEEP AND HAVE BLACK SCREEN.  I can not figure this out and am not finding any fix.

I recently switched to a dual monitor set up using my LapTop/Docking Station and 2 Monitors. (I added a second monitor to my Docking Station and closed the Laptop Screen.)

I previously used a Monitor and my Laptop Screen. (The Monitor was set as Primary, and the Laptop screen as Secondary. The Monitor was set to the Sub-D on the Docking Station.)

When I had the Monitor/Laptop setup -all open applications and desktop icons stayed in place. With the two monitor set up, the applications open on my Secondary Monitor move to the Primary after Waking Up, and the Desktop icons on my Primary shift around. (I have to drag everything back...)

This is annoying, please assist...

Ok, so I do promise that I have searched and could not find a solution to this problem.

Recently my laptop screen was stepped on ( :( ). So, only portions of the top right quadrant of the screen was still in working condition. Using this spare real estate, I set up a secondary monitor to work as my primary. While this worked for a week, the rest of the screen that was broken finally gave out and became unusable.

Here is the problem: After one restart, Vista stopped deciding it wanted to use the secondary monitor as my primary, and nothing is showing up on either screens now. How would I, without any visual display, setup the secondary to the primary again?

So this monitor is from April 09, and I've have no issues with it until now.When I boot it up, the monitor will occasionally be vigorously flashing on and off again. Just now, it continued to turn off and back on, and while it did, the display on the screen would change colors and even shake.I'm no expert on this, so I'm not 100% sure if it's the CPU or the monitor itself.My computer is an HP Pavilion p6210y, and its graphics card is NVIDIA Geforce 9100, and was also recently updated as of November.Also, when I start the computer, it occasionally displays the blue HP bootup screen, and sometimes it won't. When it doesn't, I notice that that's when the screen starts flashing quickly. When it has the blue startup screen, it's pretty much all good for a while.During use, it'll randomly turn off and back on continuously until the Amber light comes on and tells me that it is going into sleep mode. It says I have no connection via HDMI or VGA, when I clearly do and have checked multiple times.I would like to know if there's some sort of ongoing issue, maybe a malware, or if I just need a new monitor.Please help! Thank you!

My computer desk sits next to my entertainment system, and I have it connected to two monitors: the primary 22? Viewsonic LCD (DVI) and my 42? Toshiba TV (HDMI hooked in via my receiver). When I just want to browse the ?net or email, I use the primary monitor. For gaming and movies, I use the TV. For a couple of years now, I?ve had display options to always display the TV (monitor 1). If the TV was off, it would default to the Viewsonic, per the Windows feature to always default to the current monitor if only one was on. If the TV was on, it would stop feeding the Viewsonic and default to the TV, so that any games or movies would display on the TV and not cause any issues fullscreen. This way the TV being on or off determined whether the PC would feed to it or not, and I?d only turn on the power hungry TV for entertainment.

About a month ago, my monitors started behaving oddly. The PC would power up normally and load Windows to the Viewsonic, and during the load up screen the Viewsonic would power down. The only way to see the screen was to turn on the TV. This is on Windows 7 64 bit Home Premium (up to date).
Things I?ve tried:Set the Viewsonic to be the primary monitor and settings to only display on the Viewsonic. Result: If the TV is off, there?s no video to the Viewsonic. If the TV is on, it is black (as expected since I've set the monitor to receive the feed) and the feed goes to the Viewsonic.

Have you swapped out the cables and/or tried a different connection to the monitors?

This sounds like a failure either at the video card or the viewsonic monitor electronics, so I would try swapping out the video card and monitor if possible to confirm or eliminate them as the culprit, this can include the cabling.

I had something similar happen when one of my monitors went bad.

I have an HP laptop and I have been running it with dual monitors. I finally decided to upgrade to Windows 7 and after I installed it I noticed that the built in monitor of my laptop looked strange and when I opened the display settings to change the screen resolution and set the external monitor as a separate monitor rather than a mirror I noticed that only one monitor was detected and it was the external one (Generic non-pnp monitor on standard VGA graphics adapter) and the built in monitor does NOT show up at all.

I've tried the detection button, in hopes that the computer would read the built in monitor and I could fix the problem. This did not help. I tried unplugging/replugging the external monitor to no avail. I tried restarting without the external monitor plugged in and it STILL reads the built in monitor as if it is the external one. Is there anyway to fix this? I have not tried re-installing the OS, not yet anyways.

Any suggestions ?

I have a Dell P-4, 3 GHz with 2 GB Ram and an NVIDIA GeForce FX 5200 video card (dual output, one analog and one digital). I have been using one monitor plugged into the analog port. Now I am adding another CRT monitor, also with analog plug and using a DVI to analog adapter. There is a built-in video out (on the motherboard maybe?) but it was covered when the computer came from Dell and I vaguely recall a warning to leave it alone, so I haven't messed with that. OS platform is Win XP with Service Pack 2, auto security updates, Windows Defender, TweakUI (ver and Norton Antivirus.

Help instructions say:
Right click desktop and choose Properties > Settings tab > secondary monitor icon. This desktop is not showing me the secondary monitor icon.
It shows a single monitor and the message "Display: Default Monitor on NVIDIA FX GeForce 5200 (Dell)"

I realize dual monitors should be pretty straightforward, but I've run into some interesting issues that I would appreciate some insight on.
I am running a Windows 7 computer with An NVIDIA GeForce GTX 285 video card. The video card has two DVI outputs.

Running a two monitor set up, the 1st an 6 year old 19inch AOpen monitor with VGA or DVI inputs, the 2nd a 5 year old Samsung LCD TV with VGA and HDMI inputs.

I was running a DVI cable to the 1st monitor and a VGA cable, with a DVI converter at my computer, to the second. Everything worked fine. Then I moved my set up to a new room and had to move the second monitor further away. I decided, since I needed a longer cable anyways, I would try some other options.

I bought both a 15' DVI to HDMI cable and a 15' DVI cable.

I started using the 15' DVI to HDMI cable to the Samsung TV and everything worked fine for about 2 months. Then one day my TV stopped recognizing the input from the computer. It would not even allow me to select the HDMI port as if nothing was plugged in. This is particularly strange since my computer still recognized the TV and acted as if it was working fine. I tried ever variation of rebooting I could think of, TV on first then computer, Computer on first then plug in TV, and so on. Nothing would recover my picture. (I also verified plugs were properly plugged in an all the basic stuff)

At this point I'm thinking, good thing I bought that 15' DVI cable... unfortunately my... Read more

Hey guys, first thread/post what have you. Only doing this because I'm completely out of ideas and have pulled out all of my hair.

http://prntscr.com/4kgar3 Those are my basic specs.

I know enough to have fun with PC's but i'm sure you all leave me in the dust. I have always ran two monitors on my desktop up until about a year ago, one of them broke and i never bothered to buy a new one. Just used the one i had, which used to be my secondary monitor.

Now when I plug in a secondary monitor, I can't get a signal on it. They both plug into DVI-D ports. And I'm sure both ports work, cause i've played around with the settings to make the display show up on both (individually) The second monitor is a brand new RCA with DVI to HDMI cable that has never been on this computer.

I've seen posts about deleting display setting for vista because i've had about 6 different monitors on this PC in its lifetime, but nothing for windows 7 that seems to work. Do i have to factory restore. I've gone through the right click screen resolution option and the Nvidia control centre option, i've updated my nvidia driver and my AMD driver.

This used to work just fine with 2 monitors. I thought this might be the issue. My original secondary monitor became my primary monitor. And now won't switch over properly. ( i've changed the monitor to make this my main monitor in both windows and nvidia control centre )

Hey folks, I just got myself my second monitor, a Samsung SyncMaster 2232BW, and I'm having it alongside my old monitor, a Samsung SyncMaster 173T. Anyway, I've been having some odd issues I'm at a fault to understand with this. Basically, every time I turn off my computer and boot it up again, windows starts up in the lowest possible graphical mode, meaning, what 8 colors(?) and a *very* low resolution. On top of this, it's only displayed on my old monitor, and the new one is completely blank. And when I try to alter any graphical options under windows desktop preferences, it says that my graphical driver is out of date. Sure, no problem, I download the latest driver for my GPU and install it, restart the computer like the installer prompts me to, and everything just works after that.

Or atleast, until the next time I turn off my computer. Then everything repeats, except that I install the exact same drivers again, having it overwrite some files (which doesn't surprise me) and it works yet again. So basically I'm having a hassle having to install the same drivers I already have installed and restart my computer once before I can use it. So, please, I would really appreciate any help as to how to avoid having to do this every single time I boot up my computer

So heres my issue I have dual vga splitter plugged into a port on my computer and when I have both my monitors plugged in they both display on start up but after start up only one of the monitors work the monitor that stops working after boot up is a acer AL2216W, please help i cant figure this out!

A:Dual monitor issues!

Hi, and welcome to TSG.

Is the computer switching to a different video resolution during start up? If so, the new resolution may not be compatible with the Acer AL2216W. Does the monitor show any kind of an error message before it stops working?

If you are using a simple splitter cable without any kind of active electronic amplification and the computer is switching to a higher resolution at the end of the startup cycle, there is also a possibility that the cable is attenuating the higher frequency split signals to the point that they can no longer properly drive the Acer AL2216W. You could check for this by connecting the single monitor to the computer without using the splitter cable.

Hi everyone, didn't know where to post this, so went with general hoping someone can help as small stuff like this really bugs me.

I've just setup a 2nd monitor, a shiny new 30" dell, I'm using my old 28" hanns.g as my main, with desktop icons, start bar and everything on it, thats on the right hand side, with the 30" on the left. The trouble is, is that when I changed the monitors around so the mouse could go from left to right within windows, the icons where shifted to the left hand monitor the 30". I've managed to drag them back accross, but there is now a space above the startbar where I can't place any icon's, those that are placed there are moved to the monitor on the left. I also can't scroll across to the lef hand monitor at the bottom of the right hand monitor. I have placed the right hand monitor on a stand so the top of the monitors match close enough in height.

The monitor on the left, the 30" is on max resolution of 2560x1600 and the hanns.g on the right is on max resolution of 1920x1200, is there any fix for this?

Ideally I'd like to be able to scroll across from the bottom of one monitor to the bottom of the other monitor and be able to place my desktop icons at the bottom of the screen, which I can't do on the 28" atm.


PS: I'm using dual link dvid for the 30" and vga for the 28"

I've just saved a file and it was automatically saved to my right hand monitor, instead of the left hand monitor, this might be at the root of the issue, is there anyway I can change this behavour, my left hand monitor is my main, and I'd like it to behave as such regarding these issues.

Hi all,
i always had a dual monitor system. My Previous setup was a 1920x1080 main monitor, and a smaller 1300x... monitor as my 2nd monitor. I had no issues at that time.
Now i bought myself a new Monitor, a BenQ RL2455HM in 24". And here my problems suddenly starts....

1. if i scroll up and down on websites (using Firefox) it feels wrong, it's not very smooth and sometimes i get a "flickering" issue while scrolling.

2. my desktop doesn't work like it should. It seems like windows doesn't know when the taskbar ends, so that the name of the icons are unter the taskbar, and therefor not readable anymore.
Also on the last row of desktop icons (the bottom one) aren't working like they should. I can only use the First 4 and the last icon slots. The other slots aren't useable (can't place any icons there.
I really really hope that u guys can help me out.
Here are my computer specs:

GPU: 4096MB Sapphire Radeon R9 290 Tri-X
Windows 7 64bit
RAM: 16GB Corsair Vengeance Blue DDR3-1600 DIMM CL10 Dual Kit
CPU: Intel Core i7 4770K 4x 3.50GHz So.1150 BOX
Old 2nd Monitor: LG W2443T
New 1st Monitor: BenQ RL2455HM

I tested with 2 cable layouts,
First Try: Both with DVI cable.
Second (and current) Try: 2nd Monitor with DVI and the new 1st Monitor with a HDMI connection.

I also already completely uninstalled my AMD Drivers - and installed the newest stable version 14.12 Omega with CCC.

Both Monitors run with native resolution 1920x1080

A:Dual Monitor Issues

Is the problem now on both monitors, or just the new one ?

Test with just the new monitor, still problems ?

Return it.

A second monitor and your resolution setup to extend these displays should not give you any problems, and there was no need to change any drivers.

Run windows update, there is sometimes a monitor driver, it may help.

I recently upgraded to a EVGA 6800 video card and have dual monitors. With the old video card everything worked fine, but as soon as I installed the new video card the second monitor stays on until I install the driver, then the second monitor shuts off. When I look in the display properties only one monitor shows up. I cannot figure out how to get the other monitor to show up. Any help would be appreciated.

I recently tried hooking up a dual monitor setup, but am having issues... I dont know alot about computers and nobody is telling me anything that is actually was working. I figured i could update my video driver. I have NVIDIA Geforce 9500 GT, and i did update it. The issue is coming from where i go through Personalize>Display settings, you should all know this... But it registers both monitors running through it, and when i click on the second monitor, then click on the box that says "Extend the desktop onto thin monitor", it asks if i would like to keep these changes? I hit yes, but nothing happens. The box is unchecked, the power light on the monitor is still orange, and i cant move anything onto it. If anyone could help that would be great.

Hi guys, I've tried searching the web for the issues that i've been having but i can't seem to find a clear solution. I have a laptop with a GeForce GO 7900 GS video card, and my secondary monitor is a 19" samsung LCD TV (not a legit computer monitor). I understand that things won't be perfect on the TV because TV's are simply don't have resolutions like computer monitors. But anyways, i got the dual monitors to work with an s-video cable but i'm still running into some problems. Say if i wanted to watch a movie on the TV, i would drag winamp or WMP onto the TV, but when i make it fullscreen the video becomes fullscreen on the laptop display not the TV. At the same time while the laptop is fullscreen with the movie, the TV now has some of my icons that were on my laptop. Is there a way i can fix this problem?

Simply put:

How can i make a media player stay fullscreen on the TV and not the laptop? How can i stop the media player from swithing over?

They work better, but I must warn you that doing like your doing above does not always work all the time. I've tried it myself. Then you run into problems. Does the 19 LCD HdTV have VGA? If it does then use it as a Monitor Extender. So this would give you wrap around view.

I have issues getting a second monitor to work.
At startup I get a picture on both ( Window starting up... 4 little dots circling..etc)
But as soon as I reach my "Log-in page" my second monitor goes black.

At monitor settings it does not even show the option of dual monitiors.

The computer this concerns is a Acer Veriton N281G (cheap and cheerful). It has a Intel GMA 3150. I run a split cable from the computers VGA to both screens VGA`s.

The fact that I do get a signal on my second screen at start up brings me to think the problem is within Windows. Am I correct and WHAT is the solution???

Many thanks!

A:Dual monitor issues!

susidus, welcome to the Seven Forums.

Hope you're not trying to get the monitors to run in extended mode, as when using a VGA splitter all you will get is clone mode (same thing on both).

And no it isn't a Windows problem, the Intel graphics in that thing likely can't handle running both off of a single connection. It is also the Intel driver that is stopping both from running once it is loaded.

okay, im running vista 32 bit on a dell inspiron 1521 with an ATI Radeon x1270. i recently wiped the HD and did a clean install of vista using the OEM Vista cd.
before i wiped the hd i was running the same vista that was installed at the factory.
i always used to plug my laptop into my plasma tv using the VGA port on the side of the laptop and plugging it into the VGA port on the tv. i've always been able to use it as a seperate desktop so i could drag movies over to the plasma screen and still use the internet on the laptop screen. i was also able to use the native resolution on the laptop screen and change the res on the plasma to a higher res.(i dont remember what exactly)

now ever since i wiped the hd and did the fresh install, updated the drivers for all devices including the radeon x1270 (to a driver that is newer than the one i was running before) when i plug the laptop into the plasma and i try to use it as a dual monitor i just get a black screen unless i set the res to something tiny like 640x480 or 800x600. the only way for me to get a semi decent resolution on the plasma is to go into the windows mobility center (right click desktop>personalize>connect a projector or other external display) then i click "connect display (after i've plugged the plasma into the laptop) and it asks if i want to use them as seperate parts of the desktop or if i want the same thing to show on both screens. i have to select same thing on both screens then it shows up on th...

I'm currently running two samsung 23" wide screen monitors on an ATI 4870 (windows vista), however every time i restart my PC, the monitors work through the BIOS and boot sequences, however my second display turns off before logging to windows. I have to disconnect the display and plug it back in for it to recognize it.

THis hasnt always been an issue, as they have worked normally after reboot before. Something must have changed in the software to cause this?

Anyone have a fix for this?

A:Dual monitor issues on restart??

I've never ran into that one before, but multi-monitor configs seem to be the most readily breakable video setting.

I would probably try uninstalling your ATI drivers and upgrading to the latest version. When you uninstall, make sure to use Guru3D - Driver Sweeper (Setup) download from Guru3D.com or some similar application to completely clean out the driver settings.

Sorry if this is in the wrong place, wasn't sure if it should be in the forum for GPUs or Hardware or not.

I have 2 monitors (1920 x 1080) connected to my Nvidia GTX 770:

BenQ XL2430T (Primary)
BenQ E2420HD (Secondary)

I currently have my XL2430T (Primary) set to 120hz and my E2420HD (Secondary) set to 60hz both connected by DVI.

This is the first time I have had more than a single monitor so sorry if this is a stupid question.
I have noticed that if I have a game running on my secondary monitor (60hz) while I have anything else on my primary monitor (120hz), I get FPS drops for that game.
If I play the game on my primary monitor (120hz) while having anything else on my secondary monitor (60hz) there are no FPS drops.
I also get no FPS drops if I play a game on my secondary monitor if I lower my primary monitor from 120hz to 60hz and have both monitors running at 60hz, and I know that it seems stupid to be playing a game on the secondary monitor but I am still curious.

So in short it seems I only get FPS drops with games on my secondary monitor (60hz) when my primary monitor is set above 60hz.

I guess my main question is, should this be happening? Is this just the limit of my GPU or is there something else possibly at play here?

extra specs incase you need them:

Processor: i7 2600 3.40GHz 3.70Ghz
OS: Win7 Home Premium 64 bit

Currently the only real game I have tested this with is Shovel Knight and being that it isn't really a graphic intensive game, I figur... Read more

A:New monitor (Dual Setup) FPS issues

My guess would be that the graphics card has to work harder when the refresh rate is set to 120 Hz. Two different refresh rates probably causes the GPU to work even harder, resulting in lower frame rates. Also, the secondary monitor is most likely not given priority by the system, again leading to lower frame rates.

Is there a specific reason that you need to run your primary monitor at 120 Hz? Does your frame rate on the primary monitor increase if you run it at 60 Hz? Myself, I would run the monitors at the same refresh rate to avoid potential stability problems, and situations like the one you are describing. But that's just me.

Hello. I actually have 2 issues I am dealing with. My OS is XP. Here goes..

I was having trouble while on-line. Internet Explorer would close because it kept encountering problems. I called Earthlink, they checked on their end and said things were fine and we went through the wizard and it had grayed out the option for dial up and defaulted to broadband. I have dial up. When we try to add a number for dial up it comes back with error 711: a configuration error on this computer is preventing this connection. So Problem #1 is, I cannot get on-line as the Earthlink is not seeing I have a modem installed. Earthlink concluded it must be an OS error and suggested I re-install my OS. I tried to do this and got 2 error messages along the way. One said c:\windows\sisagp is needed. The other said GET IUMS could not be found and said MSDART.DLL. I had to cancel to get by those 2 messages but it appeared as though it had installed but thank goodness it must not have installed because it didn't wipe out everything I had on there. I should never have done the reinstallation because I hadn't backed up. The Earthlink gal made it seem like no big deal and I hate to say I am a little bit beyond a beginner. I did try to reinstall the Intel modem but no luck with the problem. I did not uninstall it though.

Problem #2: Now my computer will not recognize that I have a dual VGA monitors. I have a business with software installed where 1 screen is only to show 1 view for this particula... Read more

Hello,I recently picked up a 6th gen X1 Carbon and have been having intermittent issues with a second monitor connected via the USB-C port.I currently have two displays set up, both Acer 20" with DVI and VGA female ports. One monitor is connected via HDMI out to DVI in and the second via the USB-C out to converter (VGA in) and then out to monitor VGA. Most of the time this works fine and I've been able to set up to get full HD on each. Intermittently though the right monitor (USB-C>VGA>VGA) loses signal prompted by moving some application (eg, FF browser, VLC) to the second monitor, but this doesn't happen with all applications nor even given applications each time. As this only happens when prompted by moving an application I'm guessing this is some driver/hardware quirk.I tried a Google search as well as pouring over the forum but didn't turn up much. Are there known issues with dual displays on the X1C6 and/or any known remedies? Also, are there generally preferred out ports people use to connect dual external monitors? HDMI seemed like the natural first choice but I'm not sure if there's a preference otherwise from the bevy of USB ports.Regards,Chris

After I had updated my drivers ~2 days ago I started experiencing a strange problem with my monitors. After turning them back on one or both of them would say DVI- NO SIGNAL. To attempt to fix this I rolled my drivers back and then updated them through the device manager instead of the GeForce GUI since it was having issues. I have also removed the latest programs that I believe would be causing issues with regards to drivers this being nGlide (A driver wrapper used to run older games meant for 90s era graphics cards). Currently my main monitor (ASUS VG248QE if it matters) is working fine but if I hit the change source button on my second monitor (Samsung SyncMaster 220WM if it matters) to attempt to get it to draw properly, my main monitor will stop drawing and then only if I hit Source and the up arrow button on my second monitor a few times will the main monitor start to draw again. The only thing that I can see on my second monitor is the blue power light flashing in a somewhat random patterns so I have no idea what it is trying to set as the source. I have tried reconnecting both of the monitors to see if there was an issue with connection but they both seem to be fine and when I open the display manager windows is recognizing both of them correctly. If you could offer any advice it would be appreciated. Also if more information is needed please let me know what I should provide.

Thanks in advance

I've recently updated from Windows 7 to Windows 8 on my Dell XPS 15 laptop. I normally run a dual monitor setup with my 33" monitor and I am quite fond of watching netflix on the secondary monitor while gaming/doing school work/blogging/reading news/etc... however I'm noticing two things that I would like help with:

1) there is no way to run Netflix on the non primary monitor.

2) there is no way to allow the netflix app to keep playing while running another program (non app). It just exits out.

Are there app settings to get around either or both of these? Some help, please!



A:Issues running apps with Dual Monitor Set Up

can you describe your monitor? is it VGA? is it HDCP compliant? the Windows Store Netflix app requires that the graphics card driver AND the monitor be HDCP-compliant. VGA is considered an "unsafe" connection (unsafe in that the contents can be copied) and most VGA monitors are not HDCP-compliant. And none of the old VGA monitors are considered HDCP-compliant. Part of the reason why VGA monitors are extinct in this new DRM world.

in fact, this HDCP compliancy is breaking a lot of systems that have older VGA monitors where the streaming content is encrypted and fail to start. If you have DVI or HDMI displays, they are most likely HDCP compliant and you see less people having issues with Windows Store apps with these monitors.

I have a 3 monitor system. 2 of them are DVI and the other is VGA. I can choose any to be the primary display and have Netflix on any of the other monitors. However, on the VGA monitor, the Windows Store Netflix app will not run any material. The app will run and I can choose the show. But when it gets near 100%, it stops at the security checkpoint and errors out. With a web browser or with Windows Media Center, the VGA restriction is less (likely because copying the content is less than desirable from these sources) and they will allow the content to play.

Windows Media Center is the best way to play Netflix on a VGA monitor. Especially if you have a nice Windows Media Center remote. You can browse Netflix like a TV.

Hello everyone!

I've recently bought a new rig and decided to go with Vista Enteprise 64-bit version on it.

I currently have a 30" Dell monitor and a 19" Packard Bell Maestro 190W setup that I used on my previous XP rig.
Now, when I try to use my PB Maestro 190" Screen on the Vista machine, I get no signal. I can detect the monitor through the ATI Catalyst program but it cant it to work.

The monitor works and shows stuff when I reload the computer, but it goes "No signal" just when Vista Loads...
I have downloaded Powerstrip and another monitor program to try and force it to 1440x900 settings, but still no signal.. Even wrote my own drivers for the screen with a fixed resolution 640x) but no luck.
I plugged in my LCD TV instead and it worked like a charm! So i quickly switched the cables between the second 19" monitor and the TV and bam! I got the second monitor up and running!

But I had to reload the computer and I lost the output, tried several times again to repeat the procedure with plugging in the TV and then the monitor.. no luck...
The only thing I havent tried yet is to use a VGA cable instead of the DVI one..
I'm running the lastest ATI drivers (9.3)..

Just find it strange that it can detect the screen, just not send the video signals to it..

Vista installs the second monitor as a "generic pnp monitor".. And I cant seem to find any drivers on this packard bell monitor on the internet.
Anyone got a good advice ... Read more
