I have a widescreen Relysis 1720 LCD screen connected to a PC using Nebula TV and Theatertek. The standard resolution according to the manual is 1024 x 768 but it will run at 1280x768 but with a distorted Xp icons. When I run the THX optimiser on Star Wars 1 within Theatertek, I need to run at 1280 x 768 for a near perfect circle but Nebula TV at 1280 x 768 gives a distorted image? Do I need to run at 1280 x 768 for dvd, if so how can I auto switch the windows resolution before Theatertek opens and then switch back to 1024 x 768 on closing? Would I need to run at 1280 x 720 for true 16:9 using powerstrip? What settings would be required?
