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.)

A: It doesn't detect my monitor as a monitor

The audio is referring to the audio signal for the TV. I want to make sure I understand you correctly, you are using the external monitor (LG) as your primary display, not dual monitors...?

If this is the case, go back into Device Manager, rt.click the Generic Monitor and choose "Update device driver". As long as the LG monitor is the primary display, and your laptop screen is off, 'Generic Monitor' is referring to whichever monitor is active. If you are using both monitors, then you should have two monitors being shown in device manager.

As far as the mouse feeling 'sluggish', do you mean it's just very slow? What is the screen resolution of your new LG monitor? Is it the same as the laptop monitor? If the resolution is higher, sometimes the mouse will seem sluggish when using a higher resolution, which means you might have to turn up the pointer speed in the mouse's control panel. Before you update the device drivers for the monitor (which may or may not be able to be updated), try reducing the screen resolution of the LG and test the mouse that way.

Hi, so today I have turned on my PC, but the monitor did not detect it.
I have unplugged and re-plugged all the cables and it still did not work.

I have then tried a different cable and monitor to but again it did not work.

Finally I decided to unplug my graphics card and plug the monitor into the integrated graphics card but once again it did not work.

The monitor does turn on and so does the PC but the monitor does not detect it being plugged in.

Any ideas on what can be the problem? (It all worked fine yesterday)

Hi guys so i have 2 computers with the same problem, the 2nd is an old comp, so I'm not too bothered about.

I noticed my computer was getting a little noisey so i thought i'd clean all the dust out of it.
1st comp
i took the CPU and graphics card off to blow the dust out, also i blew air into the PSU fan.

The computer boots up, sounds perfect, but about 10 minutes uptime it will still be powered but my monitor just goes into standby, i tried with my TV too and the same issue.

2nd comp
I hadn't used for about 1 year, i tried hooking up to monitor and it just doesn't respond, i've tried with another monitor too and still the same, also tried using a different VGA cable. monitor remains standby, But unlike my other computer this one doesn't even display for 10 minutes!

Any ideas on what can be causing this? :suspiciou

What do you mean you took the CPU off? Do you mean the heatsink? The heatsink fan? If you removed the heatsink from the CPU, did you clean off the old thermal compound and apply fresh compound? If not, the CPU is overheating.

I connected an ethernet card to a 4-year-old Gateway desktop running Windows Millenium and then plugged everything back up and turned on the computer and the monitor would not detect a signal. I took the ethernet card out and took out and replaced the video card and rebooted and still no signal.
I plugged in two different monitors and both these monitors showed no signal. I plugged in a working video card from another computer and still no signal. I also moved the video cards to different slots and no luck. Does anyone have any suggestions? I appreciate your help very, very much.

I just upgraded from Windows 7 to Windows 10 and now my computer only detects one display rather than two. I have a Dell desktop computer and two Dell monitors. Using Windows 7 both monitors were being detected/used. Can anyone tell me how to correct. (I'm not very technically experienced, but can follow basic instructions.)

The second display shows a black screen with the message "Cannot Display This Video Mode".

right click on desktop for "display settings" - pick the monitor that shows up that message -> click it to activate -> switch correct video mode for it. its prolly too high resolution issue.

also WIN+P -combination gives you chance to use "extended desktop" which you should use to configure the resolutions

So yeah, when I wake my computer up out of sleep mode, sometimes the monitor will detect that it needs to wake up
However, most of the time, I have to unplug the DVI cable and plug it back in. When I do so, I can hear the Windows

Anyone experience this issue before? Any suggestions?

I have updated drivers for my video card, this problem seemed to only happen in Win8/8.1 I didn't have the problem in Win7

I had the company replace my video card, but I still seem to have this problem.
I tried using another PCI-E port on the motherboard and the problem was not resolved.
When I plug my monitor into the integraded DVI port of the motherboard, I don't seem to have this problem.

I just can't figure out what is actually wrong with it.

A:Monitor doesn't detect that computer woke up.

Most of the time, it is the Video driver causing the issue. Uninstall the driver for the Video Display, and then reboot and let windows install the default driver. Also check the Bios to make sure that it is up to date. Windows 8.x has had a lot of random issues, with most being Video Display issues.

I would suggest not allowing the display to be placed into sleep, just set to blank the screen. If you are leaving the machine on for long periods, just turn off the monitor. When you get back to the computer, power it back on with the power button.

Once again, switchable graphics only controls which GPU is used for rendering. It does not change which GPU is physically wired to the display outputs, and all 3 of the features I listed earlier require support from the GPU that is physically wired to the display output in order to be used. Currently, Intel GPUs do not support any of those features, so in a system with the design you want, those features couldn?t be used even if the system had a dGPU that supported those features, because the dGPU wouldn?t be physically wired to the display output. I?m sitting on an XPS 15 right now that is designed the way you want and has switchable graphics with an NVIDIA GPU that supports those features ? but my system can?t use any of them because the iGPU is wired to the display outputs. Switchable graphics does not fix that. You can shout in Caps Lock and say things as many times as you want, but that won?t make you right. You clearly don?t fully understand how some of these technologies work and what they require, but if you still think I?m wrong, go do some research and you?ll find lots of threads of people asking why their laptops with NVIDIA GPUs don?t support G-Sync or VR ? or 5K displays, which is another one I forgot about. This will be the reason why.

motherboard - asrock a88m-g/3.1
gpu - gtx 750 ti
cpu - am fx-4350 (not sure though)

my monitor won't detect an input from the gpu, and it isn't a cabling issue. i have no spare parts to test this with, so if at all possible i'd like to figure out what's wrong with it without taking it to a repairman or replacing parts needlessly.

the monitor won't display anything on screen, and will only show that it's trying to detect an input, then shuts off. it started humming a few months back, and sometimes i need to fiddle with the HDMI because no audio will play from the monitor. it's about a decade old.

i ran a stress test on my GPU a few months back and it passed. there's no artifacting / strange displays on anything; the only things maybe relevant are that on the night before my PC broke, i had a lag in an online game i was playing, but i was also streaming music at the time... the lag stopped a few minutes after i turned off the music and more or less went back to normal, so it's unclear if it was just a poor wifi connection or my GPU really dying.

the motherboard i only suspect because at the same time as my PC refused to display an image, one of the case fans stopped working. however, the case fan isn't broken, the pins simply won't register any fan in that slot now. i can turn my PC on with the start button, but i can no longer force it to turn off.

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.

Hi guys!

My computer can't seem to detect my 2nd monitor and since my Motherboard's Graphics ( HD4250 ) shows up in Device Manager as Standard VGA graphics adapter probably thats the problem.
Now the real problem is that, 14.4 Catalyst that i currently use doesnt really works for my HD4250 ( but for my HD7850 it works of course ). Last time i got my 2nd monitor working, updating the driver of the Standard VGA graphics adapter via Device Manager back in Windows 8.1 ( i use Windows 7 64 bit now ), but then Catalyst refused to work anymore.
Now when i try to update it, it says it already have the latest driver, no matter how many times i uninstall/install it. It may be very possible that i cant have both my graphics to work, but i hope there is solution for it, because i dont want to buy expensive adapter for my 2nd monitor.

A:Can't detect 2nd monitor

DeyLath, welcome to the Seven Forums.

The problem you are having is due to there being no support for the HD 4250 in the 14.4. The last driver to support it is the 13.9. You basically have two choices if you want to use 2 monitors,

1. Use the 13.9 for both the onboard and card.

2. Disable the onboard and connect both monitors to the video card if you want to use 2 monitors and newer drivers.

So, guys, I've just put a build together for a friend.

We've used the MSI R6850 Cyclone, which is a pretty hefty card with the most ridiculous fan on it.

Anyway, we're having an awful lot of trouble getting it to detect the second DVI port.

We're using 2x the same monitor, I've tested all of the cables and DVI-VGA adapters and they all work great, so does the second monitor if I plug it into the primary port.

Unplugging the primary monitor in windows makes the plug and play "dun-dun" noise as you would expect, but the second port seems to do nothing.

Theres nothing that I can spot in CCC that would be able to detect the second monitor, it's not being picked up by device manager either.

I'm an nVidia fanboy myself, so I don't know if this is actually broken, or if I have simply overlooked something major.

Last resort is to plug the graphics card into my own machine and test it, I can't be bothered with switching from nvidia to ati drivers and back again to do so though.

Any ways that I can run a decent test on this before I send it back?

I have also been looking around on the web, it would appear that this particular card has 1xsingle link dvi and 1xdual link, the dvi adapters that came with the graphics card are single link and the ports are both shaped for single link too, could this be whats causing the issue? Is it worth me running out and getting a dual-link dvi to vga adapter just to test the thing with?

A:[ATI] cannot detect second monitor

It sounds to me like you might have gotten a bad card. I have an MSI cyclone myself, and haven't experienced any of the issues you are describing, but I am using DVI cables, and haven't tested adapters...

A:Won't detect 2nd monitor

Hi and welcome.

The only thing that comes to mind is have you had any weird computer shutdown which would have made your motherboard bios go back to default setup?
You haven't mentioned is you have looked into the bios to insure that the SLI mode is turned on.
You are using 2 video cards.Correct?

Give us a little more information about what you have done to troubleshoot.
Have you turned off power to your computer and both monitors?
Have you verified the cable connections on the one monitor that is not gettig a signal?

My gut feeling is that your BIOS is the issue here.

Let us know what your next steps.

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 ?

About a week ago my friend told me he wanted to build himself a computer so I helped him pick out and order parts and gave him a few tips on putting it all together. Today he dropped off the computer at my house because the monitor won't detect it when its plugged in.

I figured it was the RAM not being seated properly or some fairly simple mistake but after close inspection I realize that he did everything right but accidentally plugged in the case's led cables into the 2 little slots on the motherboard that reset the CMOS.(the CMOS reset pins are located right above the led/reset pins). After I fixed his mistake the monitor still doesn't detect anything, though everything does turn on.

The motherboard is a Gigabyte GA-970A-UD3. Is it likely that because he had the little led cables plugged into the reset CMOS thing for the weekend he was trying to get the thing to work that he just ruined the mobo? Or should I keep looking for something else?

A:Monitor won't detect computer

the PC is ouputting a video signal and refresh rate the monitor cannot handle, as XP starts up its in basic 640 x480 and then switches to the correct refresh rate as the desktop comes up.

The easiest thing to do is use a remote control program such as dameware mini remote to connect to the machine and then change the screen size and refresh rate, its what i do when my son messed his PC up.

The fault is caused by a program or game changing the size and refresh rate and then failing to set it back when the app quits.

Hi all,

This is incredibly frustrating having spent around 5 hours on this already .

I have just bought two Acer V243hl monitors with one Nvidia Geforce7300LE card.

On startup, the bios displays on both.

Then when windows starts up, it only uses 1 monitor.

What I have tried:
I have tried to detect displays both through the display control panel and the Nvidia control panel and nothing is detected. Both monitors manage to display correctly if I start up with only 1 plugged in. For some reason the second display (plugged into the DVI of the 7300LE graphics card) only displays at a lower resolution.

Please help, I need my second monitor working!

I am clueless. Could it be to do with the fact that I have identical monitors?

When I turn on my PC, the TV monitor does detect the Windows and Asus logo and it also works when I go into Safe Mode. But the screen is just black on my TV monitor when I go to my normal settings. I tired changing resolutions and holding down the 30 second button, but nothing works. If anyone can help that can be great. If I posted in the wrong section, sorry about that.

Just got a brand new computer and two monitors. Both monitors work just fine in the primary HDMI port. But the computer will not detect either monitor in the HDMI1 or HDMI2 ports. I've updated the drivers, disabled and enabled the drivers, gone to the individual websites and downloaded drivers, changed my screen display to extended...nothing. No matter what I do the computer will not detect my second monitor.

Here is what I have:
HP Omen 870c
Intel i7-67CPU @ 3.40 GHz
32 GB Ram
64 bit operating system
Windows 10 Home
NVIDIA GeForce GTX 750 Ti
HP Pavilion 27c Curved Display monitor
HP Pavilion 27ea 27" Full HD IPS monitor

my brand new ideapad 320 will not detect my second monitor which worked as expected with my previous laptop.  When I disconnect the second monitor the ideapad does react as if a device was disconnected, but when I try to extend the desktop to the second monitor the ideapad does not detect it.  What can I do to make the ideapad detect the second monitor?  Thanks

I just installed the RC and have been trying everything I can to get it to detect my second monitor. Both monitors are identical and worked in the pre RC version of W7 with absolutely no issues.

I used the Nvidia drivers from Windows update as well as the ones from the Nvidia site. Both will not show my second monitor.

If I switch the cables it works on the other monitor no problem.. It just will NOT detect it when they are both plugged in.

A:Cannot detect second monitor GTX260

Have you right clicked on the desktop and went into the Nvidia control panel and ADDED the second monitor. you need to actually add it. the NV control panel will find it. or do you know how to do that because you did on the pre RC?

Hey guys,

I am using a dual monitor set up with a radeon 5870 graphics card. I am using a samsun 45 inch LCD TV, and an LG flatron w2286l. I have been using the two displays on/off or a year with out a problem. The TV is running through HDMI, and the monitor is DVI-D. Yesterday I had a friend come over with a lap top to play some DA II. We unplugged my monitor, and ran an HDMI cable to it, to the lap top. The monitor claimed it had a conection, but promptly went to sleep. We never could get the laptop to detect the monitor. I switched the monitor back to it's normal DVI-D cable, and low and behold, it is no longer detected by my machine. This is a major problem, as I only used the TV for movies, and the monitor for everything else. I have checked all my drivers, everything is up to date. Does anyone have any ideas on where to start trouble shooting?

Thanks all for the help!

I've recently discovered the joys of dual monitor at my friend's house and had a spare monitor lying around to try this at home, but the second port on my graphics card doesn't seem to detect anything. Both monitors work on the main (dvi?) plug but neither works on the second one. I've updated my drivers and everything, checked CCC and device manager and nothing. I've tried to google it but I can't figure out what to do. Thanks in advance!

A:AMD Radeon HD 6900 does not detect second monitor

xarche, welcome to the Seven Forums.

Both monitors work on the main (dvi?) plug

Are you using DVI cables, or are you using VGA cables with a DVI-VGA adapter on the card? If it is by adapter on the card that would be why the second monitor won't work as only one of the DVI ports on the card is configured to work with a DVI-VGA adapter.

I have a custom made computer I know nearly nothing about (a friend built it for me to use). I'm trying to attach a second monitor (a Roku TV) so I can record videos better but I cannot attach the TV as well as the other monitor (LG brand) or the other way around. Either only one of the two HDMI ports I have is not working properly or something I can't even begin to understand is at work here. I know little about what my computer is made of but I can try to figure it out if you need the information.

This setup runs on Windows 10 and has ALWAYS run on Windows 10. When I try to "Detect" the second screen--be it the Roku TV or the original monitor--it always says it cannot detect the second monitor. I'm not sure if I need to install driver updates or if the second HDMI port is even functional.

Any help would be much appreciated.

I recently upgraded my laptop to an HP 6565b with docking station from an HP 6555b with the same docking station. Almost identical machines but the new one runs Windows 7.

On the new machine I cannot get it to recognize my 23" Samsung SyncMaster PX2370. The old machine did just fine (running Windows XP). I've downloaded the latest driver for my display adapter (AMD Radeon HD 6520G) and installed the proper monitor driver for the monitor.

I'm hooking the monitor up through a DVI cable on the back of the docking station.

When I hook up a basic 17" monitor, Windows recognizes the display and it works without issue. However I can't get my Widescreen to do the same. I don't know what else to do at this point. Any help would be appreciated.

T580 (fresh from factory).  Intel(R) UHD Graphics 620 driver (12/27/2017 -  Intel Core i7 vPro 8th Gen.  Windows 10 64 bit (freshly updated).  Lenovo Vantage system update freshly updated.  (today's date: 4/28/2018) LG display plugged into HDMI port on Thunderbolt adapter which is plugged into the USB-C port on left side.HP display plugged into HDMI port on right side. Either display is detected just fine if I unplug the other one; but when both are present, it only detects one of them. This exact configuration was working fine on my T470, Intel Core i5, vPro, 7th Gen. So, bigger and better (and more $$) is worse. My bet would be on a driver issue.  (Windows won't let me install the Intel April 2018 driver - it says probably because the manufacturer did custom driver coding.)

A:T580 Won't detect a second external monitor

UPDATE: Well, ok, it DOES appear to TRY to "detect" the display when I first plug it in.  But it has no properties (e.g., Resolution) and the #3 icon on the layout panel soon disappears and clicking the Detect button won't bring it back (unless I unplug my other monitor - then it detects fine and works fine).
