Hello,

I have a Gateway GT5228 - it came with XP and i upgraded it to Vista some time ago. However, I have had to do multiple re-installs since.

About 2 years ago, I upgraded the video card by adding one to the PCI slot. Its a geForce Nvidia 7100 - And ever since I have had my monitor attached to this slot and not the original display port..

I added a 2nd monitor now to my Gateway and only 1 monitor works - the monitor that is plugged into the video card I installed.

Then, when i go into "Display Settings" it seems to ONLY recognize the "nVidia geForce" adapter and I can not get the other monitor to turn on..
(See attachment of image of my dispaly settings). I have also tried enabling and disabling the drivers in Device Manager. (However, I did NOT try uninstalling/reinstalling as I was afraid I wouldn't get a display at all..)

*Again, I have both monitors plugged in, but it seems the computer does or is NOT recognizing the original Monitor Display Port when I bought the computer and ONLY recognizing the Video Card I installed..

**Notice in the images attached - that both 1. and 2. (Generic PnP monitor and (Default Monitor)) are both trying to display on the GeForce 7100 - or so it seems)

hi, as i have some experience, when you have 2 video cards, it's big chance that they aren't compatible, but you may check bios settings, and check that integrated video card isn't disabled, and try to use nvidia control panel to set up 2 monitors.
