If your graphics card is not fully VGA compatible then then the drivers quite propably will not work. I don't plan to write special drivers for those cards because there are not enough S3 information freely available and I don't have S3 based card to test those drivers. If somebody alse has interrests to write drivers for S3 cards, then contact me . If anyone is interrested in helping to make better freely available drivers check my VGA to Tv driver devellopment program web page. Tips on using Scitech Display Doctor instead of VGA to TV drivers Scitech Display Doctor is a software which allows all kind of configuration to make for VGA card refresh rates.
Theat software can read the screen settings and then use the saved settings later.
It is possible to start Display Doctor, then start the VGA to TV driver. If the screen mode is saved successfully you sould be able to get the same screen settings as the VGA to TV driver set justs by using the Scitech Display Doctor. Scitech Display Doctor is not a free software, but you can download a free evalution version of it to your computer if you want to.
