- This is quite likely caused by either bad S3 chips or bad card design
- (or both). There was a graphics card test in one Finnish computer
- mag and they studied those cards (PC ones of course) with oscilloscope
- and the worst one was Diamond Steath, using S3 968 (or something like
- that). Output signal should be shaped like square wave but as this
- is practically impossible using analogous signals, the output is
- an approximation. And in the case of Diamond, it was more like
- sine wave (and too much damped) and so monitors have hard time trying
- to get a clear picture.
-
- Some monitors seem to require more ideal signal than others, too.
- And probably graphics chips are also quite unique, just like
- people ;-)
