I thought I was losing it until I stumbled upon this thread.
I own an older panasonic plasma 50" that doesn't have this issue at all.
However, I recently received a Samsung LED as a gift and couldn't stomach the clouding the edge lit LED was producing while watching darker scenes in movies, or games.
Not too mention how bad SD looked.
So I exchanged it for a new panny 55" plasma TC-55ST50. 1080i and P both look amazing... then I noticed the painting affect when watching Modern Family on ABC (which comes in at native 720p).
I fixed this by setting my directv box to only output in 1080i and 1080p... now the menus look great and even the upscaled 720p channels have lost the painted look.I also unchecked 720p my ps3 so games output in 1080
UPDATE: Scratch that - some games will only output in 720p and if it's unchecked on the PS3 it drops to 480p and so forth.
I still can't understand for the life of me why this is even an issue with a TV of this caliber, especially in this day and age. NOT TO MENTION when the same brand of TV that is 4 years older doesn't have this issue at all.
I attached a picture of a picture used in the directv menu that ranges from 480, 720 and 1080i for reference
I'm tempted to call Panasonic to see if they know... I'm going to go ahead and guess they don't even have a clue
