I've got a Visiontek 9250 PCI video card. See the link below for the exact model.
I'm running XP Sp3. I found "Visiontek Xtasy Radeon 9250 PCI" drivers for it through Windows Update, and I've also tried the drivers from Visiontek's website but neither one of them allow me to go 1920x1080. With the drivers from the Visiontek's website loaded it doesn't even try to go that high resolution but with the Xtasy driver from Windows update it will go that high and higher but flickers badly without any real picture.
The card listed on Visiontek's website doesn't seem to be the exact one. Again see link above and compare to whats on Visiontek's site here.
Can anyone shed light on this. Everything I've read seems to suggest it can do 1920x1080.
