Shack - thanks for the advice. unfortunately, this didn't work - but was part of the needed fix. i received guidance from another source. they, too, said to change the modes (like you said) to: "1024x768" "800x600" "640x480"
but also change the following:
HorizSync to 30.0-70.0
VertRefresh 50.0-90.0
this worked and I was able to get my display to 1024x768.
i haven't worked with the 3D accelerator. but if i hear something, I'll let you know.
thanks for the assist.
