My girlfriends mother gave her the old computer she had and after I fresh intalled xp on it I tried to plug in my monitor to the graphics card but a message came up, cannot display this. Optimized for 1078 784 or something. Sorry for being so brief im kind of in a rush. Well when I plug in the other monitor to the On board card it works as a dual display and the graphics card monitor works. But it doesnt work when its the only one plugged in. Its reading the graophics card because I can change settings/update drivers etc etc and it shows it running. In Dxdiag the driver running the other monitor is VGA.dll. Any help please? The Video card is Nvidia Geforce fx 5500
Computers shouldn't be able to output to both video card and onboard, go into BIOS click F2 or 12 and enter the menu, there should be a video option disable onboard and switch to add in card. When you next boot remember to plug the output cable into the card's ports.
