Q: Solved: Dual monitor in Vista not working. Only showing 1 monitor.

Hi!
I recently bought a DVI cable to plug my external LG monitor to my laptop to run nVidia's DualView (stretch format) across the two monitors. I'm using a beta driver (169.04 from laptopvideo2go.com), and when I enter nVidia control panel and go into the setup additional monitors tab, it only lets me choose "choose only ONE monitor". So I did that just to test that my monitor was plugged in right, and it worked. So I KNOW that my monitor is working and is being recognized by Vista. But when going into display settings byt right clicking on my desktop, it also only recognizes 1 monitor. Is it my beta display driver messing my Vista up? Or what could it be?
Any help would be greatly appreciated

Thank you

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

You can download it direct from this link http://downloaddap.org. (This link will open the download page of DAP so you can save a copy to your computer.)

for drivers to work properly in vista i'm pretty sure you have to have signed drivers, since it's beta are you sure they are signed?

Anyways, I had a dual-monitor setup on my machine with XP and it worked flawlessly. But with Vista 64-bit, I cant get it to work.

I am running an nVidia GeForce 7900 GT/GTO graphics card and I downloaded the nVidia 64 bit drivers (that were released a month or so ago). The drivers for the card are totaly up to date from the manufacturer.

My primary monitor (HP w2007 Widescreen) works fine when plugged in. But as soon as I try to extend my desktop to a sony SPD-S205F/G monitor, the display on the Sony monitor is fine, but the display on the HP monitor goes gets totally scrambled. I was able to get it configured by swapping primary/secondary configuration of the monitors, i.e. changing the DVI inputs, and it worked very briefly. But then, if you brought up VLC, the screen snowed up again.

The one thing I've noticed is that if I use the nVida control panel, it recognizes my second monitor properly as a Sony. But if you go into the Vista device manager, it has it setup as a Generic PnP Monitor. There are no Sony drivers that I can download (it says "no drivers available" on the sony page) and when I found my old disk, Vista won't let me install because it says the drivers aren't compatible.

So I'm thinking this is definitely a hardware issue, but I'm not sure if it's the display adapter (since both monitors will snow up) or if it's something with the older Sony Monitor. I don't mind swapping out hardware (my wife may, but I don't :-) ), but I want to make s... Read more

A:Dual Monitor Setup Not Working in Vista 64

I have run 2 monitors for years and within Vista since Vista started without ever an issue on the one graphic card.

Firstly when I first started I ahd 2 different screen sizes and had nothing but problems.I would say that this is your problem as most video software like VLC (high resouce software) don't like to have different resaluions running and so will pickup the best of the 2 and affect the other ones resalution.

Since I had that issue I make sure I run the exact same monitors and I've never had a problem since.

Hope that help

I recently upgraded my notebook with Windows Vista Home Premium.

On the Display Configuration, I can see two monitors. I then click 'attached' on the second monitor, and click on 'extend my desktop to this monitor'. Upon doing this, I can only see the display on my laptop monitor. Moving the mouse to the second monitor seems to work as the mouse disappear from the first monitor.
Fn+F5 seems to yield nothing as there is nothing on my external monitor.

Hello, I'm new to the forum! Thanks for building this forum!

Here is my problem:

I have a "regular" Intel Graphics card on my HP desktop. It has a VGA port and a DVI port.

When I connect one monitor (a VIZIO 26" LED/LCD TV) to the VGA port, everthing is good...
I tried to connect a second monitor (the same TV model) but it didn't work, here's what happened:

I connected a DVI to VGA adapter into the DVI slot on the PC, then a VGA cable to the VGA port on the TV and it wouldn't even detect it!

The next thing I tried is I connected a DVI cable to the DVI port on the PC and on the other end I used a DVI to HDMI adapter and connected it to the HDMI port on the TV...well NOW the second monitor is detected in the "change display" options where you "extend" the view, BUT, my second monitor keeps shutting off (it's on PC input) automatically because it doesn't get a "signal" from the PC?

I tried to "extend" the monitor, but nothing happens! I only have a blue screen that says "no siganl" on the second monitor!

Does anyone have any idea what I can do!? Will I need another graphics card!?

Any insight is truly appreciated as I am not very versed in technology!

Thanks for your time and best regards!

Beto.

I have recently built a new box with a clean install of Windows 7. Initially I only had 1 monitor and things worked fine. I decided to add a second monitor and that is when the problems started.

When the system boots both monitors display all of the bootup information and and both monitors display the Windows 7 Startup screens. This tells me both monitors and connections are good.

Once Windows loads only monitor 2 has a display on it. Monitor 1 is blank. I have check and both monitors are running the same, and latest drivers. I have gone into windows and it shows two monitors, but I can not get a display on monitor 1.

This is the first time I have had dual monitors so it may very well be a user error, but I am pretty computer literate.

Any guidance would be appreciated.

Thanks in advance.

i have used dual monitors for years. now when i click on dual monitor and play a vid i can see the vid either on the tv or the laptop but not both. i have tried the extend choice and the same thing happens. the prob with only tv is that sometimes i cannot read the tv screen even to close the page so i end up shutting down the computer. it just happened again and when my screen came up only on the tv, i could not see the start button. luckily i remembered to right click and managed to find the graphics properties choice and switched all back to my laptop screen.

please note that everything except the vid appears on both screens! i dumped the vids and redownloaded from the site, but same problem comes up.

1. if i try the tv only choice again, how can i close wmv or realplayer window by clicking on my keypad? is there a place that would give me a list of these keypad things to use instead of the mouse? if i can use the keypad it seems i can live with the tv only as long as i know i can keypad back to my laptop screen.

2. while i am at it, when i try to read print on the tv it is impossible. is that normal or is there something i can do to make it as clear as on a laptop screen?

3. any clue as to the reason the vids do not play dually?

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.

Hi,

I'm currently using two 4:3 monitors of my PC, and I'd like to substitute them with one big wide screen monitor. The only thing I'm worry about is that I won't be able to have different "spaces" for my windows that they could expand to (so I could have, for example, my e-mail on the right part, and my browser on the left).

All I've found so far are virtual desktop software, but that's not what I need. I'm looking for something that splits the visible desktop into multiple parts.

I recently transferred to a new department at work and they use a strange computer setup. I have 2 Dell towers, 2 15" monitors, and single keyboard/mouse. There's a hotkey that allows me to toggle from 1 computer to the other. The tower on the left connects to the screen on the left, and the tower on the right connects to the screen on the right.

The problem is that the desktop is supposed to extend onto both monitors. However, the left computer doesn't recognize that the right monitor is even connected. The right computer shows 2 displays in the video properties, but it can't display anything on the 2nd monitor (it shows the right monitor as screen 1, so I'm assuming it should be able to display on the left monitor as screen 2). Whenever I toggle to the left computer, the right monitor goes on standby.

I talked to 1 of the IT guys and he said that they don't support this setup -- my department set it up special for my predecessor, but the machines were re-imaged to the standard software load before I started working here. That means I probably don't have the right drivers for the video cards.

Now here's the real problem -- while I was trying to get everything to work on the right computer, I set it to use display 2 only. But since it can't use the 2nd display, I now can't see anything from the right computer anymore. How can I switch it back to use the right monitor if it won't display anything??

Hi all, thanks in advance for your attention.

I'm using a television (32p) as a second monitor in extended mode so that I can watch a movie in the TV and play a game in the monitor (this was my main goal). Monitor and TV lays in two different ambients, both connected to the same pc, one by normal VGA cable and the other by HDMI. I managed to differentiate the audio output so that VLC player sends it's audio to the HDMI (so that only the TV plays it) and the rest of system sounds, media players and games outputs to the speakers (basically only the VLC audio is directed to another output device). I reached my goal so that I can watch a movie fullscreen in the TV and play a game in the monitor fullscreen too without any interference from one another (nor audio or video).

The thing is, because I have the TV in another ambient I can't actually see what's going on in it, as I just "throw" the VLC window to the TV from my main monitor. And here's the question: There's a way to see the TV's desktop in my monitor? Without having to set it as main monitor so to not really switch between desktops.. The perfect thing would be if I could see the TV's desktop in a window like in remote desktops applications.

Just and example of what it could be:

I built a new computer recently and all was going well until I tried to set up dual monitor on this new computer. My monitors are both Acer, models AL1916W and P191W. I'm coming from a system that had 32bit xp with an nVidia GTS250 running dual monitors.

I have windows 7 up to date on the new computer and ATI drivers are up to date as well. The issue that I'm having is my P191 monitor is not being pulled out of standby and windows, as well at ATI CCC, says it only supports a 640x400 resolution. I've tried plugging this monitor in solo in every DVI port in my primary ATI card, swapped both cables, and swapped card positions, yet the monitor still stays in standby whilst my AL1916 runs like a champ and I can edit all of it's settings. I've gone through all the options in ATI CCC to set up dual monitors and I get nothing. I didn't have a problem with the P191 on my XP system.

So how can I get my P191 monitor working? ATI CCC and windows knows that the monitor is there and they both can identify the model of the monitor, but windows refers to it as a generic non-PnP monitor (the AL1916 is refered to as a generic PnP monitor).

A:Solved: Dual Monitor: Monitor still in standby

First, make sure your video card drivers are up to date. Second check in device manager to make sure it actually recognizes the monitor, if it does, remove/uninstall it, and let it reinstall the monitor. then go to the screen resolution and click on detect, if it still cannot recognize the monitor and allow you to change the resolution, I'd say the next step would be to go into your graphics card driver software, but unfortunately, I'm an Nvidia junkie and don't know how to use ATI's software.

I hope I helped =D.

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?

I am having an issue where when I launch two steam games I run into a crash. The games i'm trying to run are "Pure Pool" and "Pool Nation FX". Both games sometimes run without any issues, but occasionally when the game has ended the screen which I was gaming on will turn completely black, not even backlit, just black.

Also when I launch the games sometimes the monitor in which the game is running will be completely black, not even backlit, but i'll still be able to hear the sound.

What is really odd is that when I close the program such as the pool game, the black screen will still remain. (please note I can still use task manager on my other monitor).

Also, sometimes when I finish playing either game I won't get any black screen, but when I come to restart my computer one of my monitors will be black, not even backlit as before.

I can run DOTA 2 without any issues at all. This PC and monitors are both new purchased this week.

Hi all.

We just bought a new computer the other night and we can't get it to work with our previous monitor.

The new computer is a Gateway DX4710-09 with 6gb ram, 640 gb hd, intel pentium dual core processor, and finally an Intel Graphics Media Accelerator 3100.

The monitor is a 17 inch LCD Kogi, model L7EH.

The computer will start up normally, showing the screen for the BIOS (which by the way we can't boot in safe mode this way, no keys will switch it to safe mode) then the power light on the monitor goes from green to orange(orange being the typical standby color) and the screen gives an error. The error is "Oversize: Recommand Mode 1280 x 1024". It then proceeds to shut off and will not turn back on.

The computer works fine on our tv/monitor screen (which we'd really like to keep as a tv seeing as its tiny).

What we've tried (and had fail):
Change resolution of vista to 800x600. (Still same error.)
Boot in safe mode (Will work in safe mode, but when you change the screen resolution to the recommended mode, it will still give the same error. However, the screen will work up to the log in page then shut off.)
Get drivers in safe mode. (Won't recognize monitor, therefore can't update/get drivers.)
Set frequency to 60ghz.
Set drivers to PnP rather than non-Pnp.

My Windows 7 PC is having difficulty showing duplicate displays on dual monitors. I have done all the searching and trouble shooting I can think of. Thanks so much in advance for anyone that can offer help.

HARDWARE:
Intel Core i3 2105 Sandy Bridge processor. This chip includes both the CPU and integrated GPU cores. There is no discrete graphics card on the motherboard.

The motherboard is ASRock H61M/U3S3. The manual says this motherboard provides independent display controllers for DVI-D and D-Sub to support dual VGA output. DVI-D and D-sub can drive same or different display contents.

SETUP:
On Windows 7.
Two montors are pluged in: one D-Sub monitor and one DVI-D monitor.

RESULT:
Only the D-Sub monitor displays.
The DVI-D monitor says "no signal" and then goes on standby.

WORKAROUND:
There is a way to duplicate the display on both monitors, but it requires manipulating the cables after every bootup:
Unplug the D-Sub monitor from both the power and the motherboard port.
Plug the D-Sub cable into the motherboard's port.
Set multiple displays to "duplicate" (right click desktop, Screen resolution > Multiple displays: Duplicate these displays, click OK button).
Plug in power cord for the D-Sub monitor and turn on D-Sub monitor.
Now both monotors show the same display.
This proves that my PC is capable of duplicate displays in Windows 7.

A:Dual monitor not working

What graphics card are you using (make and model) and are you drivers all up to date?

Right click on your desktop and select Properties.
Select the Settings Tab
Do you have two screens showing in the diagram on that tab, if one is 'greyed out' select it and tick the box at the bottom labelled 'Extend my windows desktop onto this monitor' or something very similar.

If you are using NVidia or ATI control panels there may be an option in there which activates your dual monitor, it is probably set to single screen by default. I am not sure exactly where the option will be but you should get something like a dropdown menu listing 'Single Monitor', 'Clone' or 'Dual Screen'. You need to select the dual screen option.

I have a dual monitor set-up which was working fine with Windows 98SE. Each monitor is connected to an ATI XPERT 98 (RAGE PRO) PCI video card - each card is installed in a separate slot.

I installed Windows XP professional yesterday and ever since I did so, the primary monitor is recognized but the second monitor is not. I went into Device Manager and sure enough, it states that the second video card is not functioning. I did the recommended solution of deleting the second card and then reinstalling it - and that has not taken care of the problem.

I don't think that it is a driver issue since one of the monitors is working fine. I checked the ATI web site and it indicates that the drivers that come with the XP installation cd should work fine.

So, I am out of ideas on how to solve the problem. I don't think that the card is bad since it was working right up to the time that I installed XP Pro.

Does any one have any ideas as to what I should do to get around this problem?

Thanks.

Hi,
in fact it might be a problem with the WinXP installation.
I heard there are loads of things that can go wrong whenn installing it.
so maybe try to re-install it.
usually XP should automatically detect and work with all monitors & graphics cards.

what I would like to ask you though is how you got both monitors to run under win98se.
I've got an old geforce 2MX PCI and a geforce 4 ultra AGP(where my monitor is currently connected to) and would like to buy a 2nd monitor and connect it to the Geforce2.
will I need a special win98 driver or will it work automatically?

Hi Resonate, welcome to the Seven Forums.

Did you select correct HDMI input from your TV's settings? For instance in my Philips TV I have connected two computers to it with HDMI as this photo shows:
If I want to use the TV as display for my Home Theater PC, I need to select HDMI 1, and for the server HDMI Side. As the settings and remote controls are so different, I cannot tell you which button to press to get the input signal selection menu on your TV.

Hi I just installed Vista on my Dell and the dual monitor is not working.
Dual monitor worked fine when I had XP.
When I reboot the computer, it will show BIOS/Windows page on both screens but after that, before the desktop shows up, the second monitor would turn off.
I can't locate the 2nd monitor in the device manager and when I attach the 2nd monitor in the display settings, nothing happens, the 2nd monitor does not turn on.
Please let me know how I can fix this problem. Thanks!

A:Dual monitor in Vista

hey, i had some problems setting dual moniters up too, but firstly i had to make sure i had the tablet pc tools thing installed (control panel->programs and features->install/whatever windows features[apologies for inaccuracy]) because i had an error connecting it without... Then check your display settings (e.g. control panel->personalization->display settings->monitor tab) and see if it recognises that 2 monitors are able to be used(and make sure extend desktop... is checked on the second one if found... If you cant find anything there then i recon trying to use your laptops "presentation" feature (usually fn+F[3-5]) one of the functions and see if the monitor responds... if it doesnt then you may need drivers etc?

i hope i helped at all...
maybe shove your dell's model details online (or google and see if anyone else has problems)...

I found it very hard to sort this because of vista's new control panel thing haha...

oh and on another note i realised i had disabled a service (start->run->"services.msc") which mentioned dual monitors... maybe you've done the same?

p.s. if you do get it sorted see if when you remove the second monitor the taskbar becomes transparent because thats a problem i'm having right now

Again i hope i was of any use,

Hi
Operating windows 7, I have been using a second monitor through HD lead for months with no problems, it has now stopped working,, cable ok, monitor ok.
Detecting monitors works properly, mouse moves off screen to other monitor's area.
However, the monitor reports 'no signal', displays no image or sound. Disconnecting the monitor also worked as expected, and the system would reconfigure for single monitor mode.
I reconfigured system to an earlier date but problem still here.
Any suggestions and im no computer expert :)

Thanks in advance

A:Dual monitor stopped working

Hi,
For the issue, please try the methods listed as below.
1.The laptop has an Function key (Fn key next to the windows start key) on the keyboard. Press and hold the key, and hit the F5 or F8 key or that F key which has the monitor icon on it (it is F5 on toshiba and F8 on dell).

2.Sometimes a high resolution to an extended screen can also be a cause of non-display. Just reduce the resolution of the additional monitor to 800X600 .

3.unplug power cables and video cables from wall socket and back of computer and monitor, wait for 10 minutes and plug all cables back in.

4.If these methods still don't fix, then just as Balaji
said, your next bet is reinstalling your display device drivers.
Update a driver for hardware that isn't working properly

Hi
I am trying to setup a dual monitor system, the same as I had with Win 8. My main monitor is plugged in via a HDMI cable to one graphics card, and my second monitor is plugged in via HDMI to an onboard graphics card.
I have setup the displays to extend, and it sees, and correctly identifies the second monitor, and when I click extend it briefly shows the desktop on both (correctly) bt then the second monitor goes black, although the light stays green indicating it is receiving a signal.

Can anyone advise on how I can get the second monitor working correctly.

I have updated the graphics cards (today).

Thanks in advance,

I have two monitors. One has a HDMI>HDMI cable and the other uses a VGA>HDMI cable, with the VGA end being connected to my tower. This setup used to work without a problem, but then it slowly started having problems. Now, the furthest I can get is having the HDMI>HDMI monitor working fine, and the other monitor working in 1024x768 resolution. The native resolution for both my monitors is 1366x768. When I use the Window's Screen Resolution to change the resolution of the second monitor, I get a message saying "unable to save display settings" and it loses signal from my second monitor and stops working. I'm using Windows 7 and a GeForce GT 545. If there's any other info I'm leaving out, let me know and I'll update it. Thanks

I'm using a T430s and a mini dock plus series 3. This is the dock with the dual DVI, dual DisplayPort, 1x VGA. I do not use the laptop's built-in screen; just the 2 external monitors. Intel HD4000 graphic chip and Nvidia Optimus/ I previously had 2 20" monitors with a 1680x1050 resolution using DVI-to-DVI. They both worked fine. I upgraded to 2 24" monitors with a 1920x1200 resolution. The laptop is not recognizing the second monitor. I have tried:dual display port (dock side) to mini display port (monitor side): only 1 monitor recognizeddual dvi (dock side) to HDMI (monitor side): only 1 monitor recognizedI ruled out monitor and cable problems by swapping...each by itself works fine. Looking up specs, I believe this resolution should be supported by DP or DVI. Can anybody confirm that this is a supported config? Any ideas what is wrong? UPDATE - I did try 1 DP/mDP and 1 DVI/HDMI: this does work. However, its not an ideal solution because it would interfere with the monitors ports which I want to use for a second PC. UPDATE 2 - OK, now I am beyond aggrivated.

A:Second monitor not detected: T430s with Mini Dock Plus Series 3 dual external monitor

Fixed; was a driver issue. Problem seems exclusive to a Dell u2415 on DP port 1 only of the dock or to the laptop's DP port (at least for the couple monitors I tried). It's possible it could affect other monitors. My starting point: 9.18.13.4535 / 9.17.10.2843 (Nvidia /  Intel) The latest driver from Lenovo is 9.18.13.4535 / 8.15.10.2725. I'm not sure how i have a slightly newer Intel, but that's what it was. I couldn't install the Lenovo driver. I also couldn't install a newer driver from Intel (10.18.10.4276). In both cases Windows or the Intel installer stopped me saying the mfr provided the drivers and that the installed version was up to date. I worked around by first rolling back the Intel driver. The manual (.zip) install of the latest intel driver worked. This immediately fixed the Dell u2415 on DP port 1 and laptop's built-in DP port.

Hi.

I recently got a monitor from one of my friends saying that it was broken. Its a Dell 19in LCD. I have my main monitor a 22in Samsung wide screen So i just plugged it into the second DVI slot on my graphics Card. When i went into the display config i set up dual monitors just to see if it was working. The dell monitor would blink up then quit on me.

When i was messing with the Display settings I made the Dell. Not my Samsung the Default Monitor. I unpluged the broken Dell and restarted. Now my computer regognizes the Samsung as the second monitor and it just shuts it off and recognizes nothing as the main.

I managed to get it into safe mode and it recognized the samsung but every time i try go back to Normal Start the screen is blank.

How can i get it to recognize the Samsung as my main?

Hello I basically need conformation that I'll need to buy a new monitor in order to have a dual monitor set up with my current system. I'm not super tech savvy so if you need any other info please let me know.

I have a Radeon HD 6670 with 3 ports, an HMID, VGA (which is my monitors type) and DVI. Each port has a stamp next to it that indicates what port type it is/supports (the VGA has a CRI stamp next to it though). My main VGA monitor works fine with the VGA/CRI port, but my second I have to use a VGA to DVI adapter and it's not working.

I've gone through a lot of forums, and found some conflicting information. So I really want to know is it possible to use a converter/adapter or will I need to just go out and buy a new monitor that has a DVI hook up?

I hope I don't need a new monitor, I'm on a very tight budget. (la sigh)

A:Radeon HD 6670 Dual Monitor setup not detecting 2nd monitor

I would try one of these before giving up on the monitor:

Rosewill 10ft. DVI-A (24+5) Male to HD15 VGA Male Analog Video Cable w/ Ferrites Cores, Model RCW-900 - Newegg.com

Forget adapters, you might not a have a compatible one, the DVI connector has many variants.

Look at that cable end and make sure it would fit on your video card's female DVI connector (it should), it's DVI-A (analog only) to VGA which is analog only....

Running dual monitors in Win 10 and when going through the Color calibration steps on monitor #2 (Control panel / Display / Calibrate color) the settings stick as long as the 2nd monitor is active.

If I switch to single display (Windows Key + P / PC Screen only) then the 2nd monitor loses its color calibration. Also anytime I reboot my PC (Even if I have both monitors active) the 2nd monitor loses my calibration.

The 2nd monitor has a fairly strong bias for the color Green so I can always tell right away.

I'm probably overlooking something and was hoping someone might of dealt with this before

I have an ATI Radeon 4670 card. I have not had trouble getting it to "Dual Display" in the past. Usually I wanted to do an extended display. I am now trying to get it set up with my HDTV with HDMI. I have added the Realtech drivers and HDMI adapter to the video card and have been able to get HDMI and digital sound to the HDTV, I am trying to get the two displayed as clones.

The problem I am having is after getting Catalyst to display the HDTV, I have lost the image on the monitor. In the process of trying to get it back to both displays I have accidently made the HDTV an extension of the monitor. Which is really a cluster as I can not get to the control panel to make any changes. All I have is the extension showing on the big TV but none of the controls. I tried rebooting in safe mode but was unable to access the catalyst control center as it did not boot in safe mode. The big plus is that in safe mode both screens are visible, but I can not undo the Catalyst settings. I am now running a system restore which will take me back to tomorrow settings, which is not ideal but better than not being able to access anything outside of safe mode.

How do I get the TV and monitor to display at the same time?

Initially had a GeForce 8400GS 512MB PCI video card and was using the on board video (Biostar G41 M7 MB) for dual VGA monitor setup.

I've installed a Radeon HD 6670 1GB PCI-E video card with monitor one setup via DVI to VGA adapter on output one and 2nd monitor on VGA onboard video.
I cannot get the second monitor to detect in any configuration. Tried looking in BIOS of MB, using 2nd DVI (w/ vga adapter) on Radeon card.

Am at a loss and I hope I have provided enough information for some assistance.

I don't understand why you are using a combination of DVI (to VGA) out of your HD6670 to one monitor, and also using the VGA out of your motherboard to the other monitor.

Am I interpreting what you've done correctly? You are using just the DVI output from your HD6670 through a DVI-to-VGA adapter and on to your first monitor, and also using the VGA output from the onboard graphics of the motherboard to feed the second monitor? If so, this is very wrong.

Your new HD6670 has TWO video outputs of its own: one is DVI, and the other is VGA. You should connect your second analog monitor to the VGA output of the HD6670, not to the onboard graphics VGA output.

Also, if you can disable the onboard graphics in the BIOS that's definitely what you should do when you install an external video card as you've done. At the very least you should give priority to the new PCIe video over PCI (which was your old GeForce card, and probably o... Read more

I've had dual monitors for years now and have never had this problem. But I also have no screen saver.

If you put your system to sleep why would you want a screen saver? All that does is keep the system active and running - which is the opposite of what sleep does.

Remove the scree saver and see what happens.

About 6 months ago i invested in a second video card to use with an old monitor and a new PC. After much trial and error i eventually got it all working.

A couple of days ago i re-installed windows however and therefore all my settings have been reset and am now havein problems, and if i remember rightly the same ones as before. But for the life of me i cant figure out how to solve them this time round. So any help would be appreciated.

Spec -

2x plug and play monitor (almost sure it has nothing to do with these so wont add details)

1x Nvidia Geforce FX 5200 (AGP) with fully updated drivers (from manufacturers website) (the monitor off this video card works fine)

1x ATI Radeon 7000 (PCI) fully updated drivers (without catylist command centre however due to some installation problems. I had these before when both monitors worked fine..just the drivers) - Problematic monitor

Bios - Dell Computer Corporation A12 (newly updated) (I heard somewhere that this may have an effect).

The Problem-
On my second monitor (Radeon 7000 (PCI) whenever i try to move a frame, scroll in IE etc the refresh rate is appaling. Entire lines get moved at a time.
The only time the refersh rate does not slow is when moving the mouse and scrolling through files in c drive as far as i can tell.

Well, could be bad drivers... nvidia and ATI hate eachother, so I dunno why you got cards like that, could be a driver conflict from un-updated windows files, that is to say, uninstall drivers, update everything on windows, re-install newest drivers.

I've been running a multi-monitor setup for a while now, with an ASUS VG248QE 144Hz monitor as my main, and one or more spare monitors as secondary displays. I've set the ASUS monitor to 144Hz without issue in the past, while the other monitors stay at 60Hz.

The other night, Windows wanted to update. I figured it was the usual patch session, so I let it do its thing. However, after restarting my computer, I noticed that my ASUS monitor would only operate at 144Hz if it was the only monitor plugged into the system. When I try to set it higher in the Nvidia control panel, it just reverts back to 60Hz after applying changes. I updated my graphics drivers (though I was only one version behind) and even sought a special ASUS driver for the monitor to resolve the issue, but nothing has helped.

Did Windows recently add a forced refresh rate sync between all monitors recently? If so, that really sucks because I only own one 144Hz monitor.

A:Dual monitor setup locks 144Hz monitor at 60Hz

Are you sure the other monitors are independent (dual or multiple mode) rather than cloning the main monitor? If they clone the main monitor, then this explains the 60Hz refresh rate, as all settings (resolution, color depth, refresh rate) should be common for all monitors and the others can only do 60Hz.
