Hmmm, interesting. Part of my problem is that the monitor type was
detected as a generic LCD, and Gateway did not provide any specs on what
the monitor can do with regard to the HorizSync and VertRefresh. I
understand that you can damage a monitor by using inappropriate values
here.
Do you have any guidance on how far I can push these?
