This really does sound like a refresh rate issue. If it changes from
60->75->85 as you suggest, it is settings related. It is also possible you
video settings you need cannot be driven by your video card but that usually
happens with weird resolutions and 1024x768 is not weird. What is weird is
1024x768 is not usually a wide screen. Plus refresh is not independent of
resolution.
So off to Google I go..and I see it rated for 1280x720. Now that is a
resolution I might expect of a wide screen DLP TV. So lets start from
scratch shall we?
Select a resolution of 1289x720, this is beside the Monitor tab, the Adapter
tab - Click on List All Modes. A list will appear. Pick as close to 60 Hz
as you can and save.
If this works and is better, if you have florescent lights near by and see a
faint flicker, and in the List All Modes selection there is 59 or 56 Hz,
select it. It is not likely, but possible higher hertz will yield a better
picture. You can try it, but stick to the native resolution.
If that does not work, let us know what kind of video card it is. It is
also listed in the advanced properties Adapter type area.
