Second Monitor Working But Not Detected
Dec 28, 2009
So I got a new monitor for xmas, the LG Flatron W1953T and I wanted to get it running with my Dell monitor. I have an onboard NVIDIA GeForce 8300 and at first just tried to plug the new monitor into the DVI port but I think it's broken or something.
Anyways, I bought this Triton Technologies External VGA video card that I just plug into a USB port, and now I have both monitors running through VGA, and my second monitor is up, but the resolution just looks terrible on the second one, and when I go to adjust resolution or whatever it says I have only one monitor and if I hit detect it doesn't come up.
In my devices menu it says I have the dell menu, and then two other "Generic non PnP monitors" even though I only have one other monitor connected.
I also go to my NVIDIA control panel and it doesnt say the second monitor is detected.
Both monitors are working, like I see my desktop background on the other monitor and I can drag stuff over to it but its just not detected or something idk. I want to download Ultramon too, (Or should I get something else w/ windows 7? I heard you cant have two taskbars w seven.

I'm running into this and issue and I can't peg down a cause. I recently updated my Vista HTPC to Windows 7. When booting up I can get into the OS, but the screen goes black shortly after.
I have tried two monitors: the Panasonic plasma just goes black and when I try Samsung Syncmaster LCD it looks like it's searching for digital, then analog sources.
I have an Nvidia 8400 GS card and I've tried both the 191.07 and 195.62 drivers. I've also let Windows install the drivers after uninstalling the Display Adapter in Device Manager in Safe Mode.
When I start in Safe Mode I cannot recreate the issue. I tried uninstalling/reinstalling the drivers in Safe Mode.

I was using two monitors with two ATI Radeon 4800 cards and that worked fine. I just purchased another monitor (Samsung) and now I cannot get it detected. The device manager is only showing 2 generic PnP monitors. I'm not sure why they would not be the specific monitors brands either (one Samsung and one Acer).
Any way of getting the third monitor detected? I've heard about deleting the graphics card drivers and then the monitor might be detected. But I do not know the procedure for doing that.

I'm running a ASUS P8H67-V REV 3.0 mothboard which has a VGA and a DVI-D output. When I connect a second monitor w/ a vga to dvi-d adapter, it does not detect the monitor at all. I've tested the DVI-D port with a dvi to hdmi cable to my TV, at it works as soon as I hook that up. Below is the onboard graphics info.

So I just upgraded from a GTX 560 TI to a GTX 670 and now my computer can't detect my second monitor. My main monitor is plugged in via DVI while my second computer is plugged in via HDMI. I've been on nvidia control panel and tried finding my second monitor there on the "multiple monitors" section, no second monitor there either.

Radeon HD5570
Win7 Professional 64 Bit
Annoying intemittent fault whereby the monitor is incorrectly detected as a generic model instead of an LG L192WS and the screen resolution changes to a lower setting which loses a large percentage of the desktop. I've updated to the latest AMD drivers as that seemed to work for others with a similar problem but to no avail. it takes 5 mouse clicks to open desktop and reset the display to the correct one, but after spending quite a bit to speed up my system I begrudge the time!

I have an Acer Aspire 5741-5979 using a graphics card of Intel (R) graphics. This is a new issue I have had recently. I used to connect an external monitor to my laptop, and it worked fine. The issue is that the laptop still detects the external monitor but the external monitor does not receive a signal when I plug it in the VGA (blue trapezoid connector) have played around with the display options an exhausting amount of times and nothing works there. I tried what worked before (extending the display) and trying to clone it. I thought it might be a driver issue and I reinstalled the driver, but this didn't seem to help either. I have used many monitors when it worked, and also tried different monitors after it stopped working to no avail

I've looked in several forums but didn't find the solution, my mouse was working perfectly (touchpad still working), until I installed a joystick driver, and then it didn't work anymore, it is detected, the mouse emits the light it usually does, and when I go to Device manager, it's there, driver up to date, and "the device is working properly", it says.

I have two computers. The monitor (Acer) on #1 quit working. I switched monitors. #2 monitor (samsung) didn't work on #1 either. I thought it might be my computer. My brother got his monitor working with it. We thought it might have been my cables. I bought new ones. I tried it (with new cables) with monitor from #2. Didn't work. I put the orignial monitor back on, and it works. Now the monitor from #2 doesn't work on #2. I think it might be a driver issue, but not sure.

I just bought a new 23inch Samsung Monitor (S23B370). It have full HD support and also have an HDMI port. I bought a HDMI cable which have HDMI on both ends. I have a VGA (Nvidia 210) which also have an HDMI port. I connected the monitor's HDMI out to the VGA's HDMI port with the new cable and booted. Nothing came. I even set the Monitor's settings to HDMI. But nothing happened. It says check display cable. Why is this? How to fix it? Have I done something wrong?

I bought a Samsung HDMI monitor yesterday (model: S22B370H) for my Z68P-DS3 motherboard which has only an HDMI output. The monitor was working fine when connected to my laptop, although with some flickering. When I connect to the PC, rarely it shows a display till the Windows Startup booting screen, after which it is totally blank. The monitor is recognizing and HDMi input but is not displaying it.

A friend just bought a new HP laptop running Windows 7 Home. They want to connect their old Gateway monitor to the laptop to use as a dual-screen setup. They shut down the system connected the monitor then turned on the monitor and booted the system. When the desktop displays on the laptop it also comes up on the external monitor for just a second and then the monitor goes black. They have also tried connecting the monitor while the laptop was already up and running with the same results. The monitor had been working fine with their old Windows XP desktop system.

I have build 7068. From the start my screensaver and power options are not working. The problem is sometimes they DO work. I am having trouble diagnosing it because of that fact. What would cause this? I just want the monitor to turn off 30 minutes after stop using the computer. That's the main issue. I go to "power options" and set it at 30 minutes and never put to sleep. What am I missing here?

I have a IBM Thinkpad T30 with a graphics card ATI Mobility Radeon 7500. I have an external monitor plugged up. On xp I can dual split easily! I just installed windows 7, and it doesn't detect the external monitor. I right click desktop, and select screen resolution. I click detect and the only screen detected is my laptop screen (not the vga external screen). I checked the IBM website, and the video drivers are only for windows xp. I tried to install the driver for xp on windows 7, and an error pops up and says "Setup was unable to complete the installation. Try to setup your display adapter with a standard VGA driver before running setup"

Yesterday, I got a balloon notification saying that there were some Windows Updates available. I like to keep my PC up-to-date, and since I wasn't in the middle of anything urgent I had my Windows 7 32-bit PC download and install them. WU asked to reboot my computer, so I got to a stopping point and clicked reboot.When I rebooted my PC, my 2nd monitor stopped working and wouldn't detect.So I downloaded installed the latest drivers and restarted, nothing. Tried rolling back to a restore point before the updates, nothing. Uninstalled the video card and rebooted, nothing.
I have an ATI Raedon 3600 Series video card, installed into a Dell Optiplex 360, running 2 Dell 19" LCD monitors. Nothing super fancy or extravagant going on hereI am a bit at a loss. I was going to maybe take out the video card and try reinstalling it physically and "softwarically". But I do not think that will aIt was working fine for months, and so I am guessing it has something to do with the Windows Updates that were installed.

I'm on a Sony Vaio laptop with a second monitor connected with a VGA cable. I just switched from Vista to Windows 7 and my second 22" monitor is not being recognized under the resolution screen. It worked perfectly fine on vista just hours prior. I tried hitting the detect button, reconnecting the monitor, and restarting. What am i doing wrong?
It might be my graphics card, im pretty sure i have a nvidia geforce 7200m gt. cant seem to find drivers for it anywhere. My computer keeps telling me all my drivers are up to date, yet my second monitor is still not recognized. this doesn't make sense. Should i just go back to vista?

2 weeks ago my Ink Status Monitor for my Epson Stylus Photo R360 was working fine (Windows 7 Ultimate 64 bit),then suddenly it just stopped working (I'm not aware of any recent changes I had done that may have affected this). It still works on the printer display,but not on the PC. If I select "printer preferences" it is greyed out,but the box to disable it is unchecked. I have uninstalled and re-installed the drivers countless times now (Windows keeps wanting to install Epson ESC/P2 which does not monitor),but I have downloaded the up to date driver from Epson and still no joy.

I've recently purchased a Samsung T23A750 monitor and to my disappointment when I try to watch a movie the built in speakers are not functioning. I have a Sony Vaio Z216GX connected via HDMI to the monitor (HDMI-DVI) port. I can definitely see the video, but no audio is playing from the speakers. The built in speakers are not at fault- I did a self-diagnosis of the monitor and the speakers seem to work fine. I also set the monitor as the default for the audio and even when Win 7 says its functioning properly, the speakers still don't work. Conversely, setting the default to my PC speakers work fine. I'm sure its not the HDMI cable- I used the same one to hook my pc to my tv with everything working fine.

I am running a dual monitor setup with my TV hooked up via HDMI to my laptop.
Everything was working fine before, I always had the laptop as my main display yet I could play a video or a game fullscreen on the TV.
Since a couple of days, as soon as I put something in fullscreen, it immediately goes on my laptop, regardless if it's open on my TV or my laptop. I don't remember changing/installing anything that could've changed that...
I checked a bit in the AMD vision software and the Windows control pannel but I can't seem to solve my problem without switching my TV as the main display. I also made a quick search on google as well as here but the problems were mainly with Flash, which isn't in cause here.
Here are my system specs:
Toshiba Satellite L75D
Windows 7 home premium 64-bit
AMD Radeon 6520G

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 standalone 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.
