I've been using Windows 7 for two months now on my desktop. I bought it along with a nVidia 9500GT video card and have been using it fine. The VGA cable was connected to the video card and all was well.

Today I bought a new monitor to use dual monitors and I'm stuck trying to make them work.

I left the first monitor connected to the video card, and tried connecting the second monitor to the video port on the motherboard itself that comes with the motherboard.

I can't seem to make it display anything, it doesn't even detect the second monitor.

Here's a screenshot of the devices:

Any suggestions on how to solve this?

  • Could it be that this motherboard doesn't have a default video card? I mean, it has the same port the video card has, I'm just assuming. Apr 13, 2011 at 20:07
  • You have to connect both monitors to the video card when the PCIE card is inserted the integrated graphics are disabled. Apr 13, 2011 at 20:11
  • @Kyle: Is there a way to enable both the video card and the motherboard? And is there some risk in doing that? Apr 13, 2011 at 20:13
  • @Sergio on most motherboards, no. See this question for more info: superuser.com/questions/211106/dual-monitors-on-optiplex-755 Apr 13, 2011 at 20:14
  • I know for a fact there is a question that goes further into details but I can't find it right now... another one:superuser.com/questions/44781/… Apr 13, 2011 at 20:14

Many motherboard manufacturers include some bit of logic that will disable the on-board video card if there is an addon-card installed. Sometimes you can get lucky & they include an option in the BIOS to re-enable or set the onboard as default which will allow both to run in tandem.

I couldn't help to notice that you have a 9600GT installed... most 9600 cards I've seen have 2 video ports already (one DVI & one 15-pin DSUB). More than likely, you would be better off using both ports on your 9600 rather than relying on the onboard video-card.
