Trouble setting up dual monitors on Windows 7 desktop pc


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?


Answer



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.
