@Tempest:
That's the info that I needed. Thanks! :-)
I use 1024x768 16-bit non-interlaced and it works great. CybergraphX v4 here too, with the latest patch installed.
Too bad that 24-bit modes are limited to 800x600 if you want non-interlaced display, however considering the age of this technology, regardless, I bet that the card was quite a monster when it was released. :-)
