I have a GeForce 2 mx/mx400 video card in a athlon 1700 xp running windoes xp home, with a new KDS VS-190is 19 inch monitor. For some reason every since I added new monitor, I cant run high ress, well anything over 800x600 & no 3d accel. when I do it locks up.Do I need a new video card? Is mine not capable of handeling high ress 19 inch?Can anyone help me out with this problem??? I have updated all my drivers, even checked my video card, looks good & says its working properly.
