You should re-boot the computer or it may not detect the new screen(more so if it is over VGA)
4350 @ 1920 x 1200, so yeah, it works.
Also had the same screen years back pushing the same resolution on a Geforce 4 MX
, but that was not too god under media center @ that screen resolution
Even old cards should do that resolution.
If you do chance the card, please ensure the computer actually has the PCI-E slot needed. Many older systems will still have good old AGP(like that Geforce 4MX).
