Only 4:3 screens.
I had a 100hz panasonic but i found it had a very unnatural picture with games.
Edges in your typical psone game (or other early 3D games) were very highlighted and resulted looking ugly overall.
I also had issues with RGB scart, there were horizontal lines one the screen which i didn't have with other TV's in RGB.
What about samsung, lg, toshiba, sony,... ??
From my experience i had issues with expensive TV's.
Go to cheap with some unknown brands and i found issues to when i switched to rgb, the image softened when it supposed to be better.
