I hate bumping ancient topics but I believe this is important enough to warrant it, like how i fixed it!
So, for those who dont want to read the whole convo i used 4 different monitors,
1. A ViewSonic 1080p Monitor Utilizing a VGA Port (i managed to get this one to work fineish)
2. A Thinkvision Display (1400x900.. wtf resolution is that?)
3. A Dell Monitor (1152x664 again, wtf)
4. An HP Monitor (1024x768)(Works Perfectly!)
well, as you can planely see Mac OS 9 doesn't like weird ass display resolutions.. or at least the Rage 128 doesnt
(damn 14 year old me was dumb)
TLDR: Increase your monitor sample size, thats the problem.
