These include 800 * 600 16 colors, 1024 * 768 16 colors. 320 * 200 256 colors work ok, only the 640 * 480 256 color mode doesn't work. The picture looks like the wrong horizontal frequency is generated, I see a picture but this is repeated 6 or 7 times horizontally on the screen. I have tested the card with VPIC 34, CSHOW 8.21 and VUIMG 2.90 all have the same effect. The graphics chip is a Trident 8800, I think the card is simply broken but perhaps somebody knows a solution?
