Check the settings of your video cards and make sure that all over-/underscan options are set to zero first. Teh best physical resolution should be 1920*1080 for this TV.
I thought this would fix the problem when reading it but it did not.
Your Res isn't going to look any better above 1920x1080 (aka 1080p). In some cases it'll actually look worse.
That was the highest. I went to the 4th option worse than that and it looked best. This has to be bad scaling right?
