I'm restoring the whole Windows folder to a fresh install for every driver I try.

Very strange, I wonder what is preventing the video card drivers from working then. Here's an extreme case: try to install the english version of Windows 3.1x to a spare drive and leave only the default system drivers (avoid all third-party drivers, even for the mouse). If all that fails, then you have some unique case here.

Maybe the card/RAMDAC defaults to (or is only capable of) interlaced 87Hz at 1024x768 . LCD screens typically do not support that.

Thanks for pointing that out, I know for a fact that this monitor doesn't support 1024x768 87Hz interlaced mode and the driver/card indeed defaulted to it. Fortunately, there is an utility called "VMODE" that allows Tseng cards to change refresh rates, I was able to change from 87Hz int. to 60Hz and now the monitor displays a nice 1024x768 resolution image at 256 colors.

Here's a helpful thread for more info about "VMODE" and a direct archived link to Tseng drivers and utils.

Cool! Glad you got it to work.
