480p
The TV didn't have many issues with 480p content. There was a 3.5% overscan, some minor moire interference, and some other very minor problems, none of which amount to much.
720p
There were even fewer issues with 720p content.
1080i
The main problem with 1080i playback is moire interference. We saw some minor false coloration and fine patterns were often replaced by entirely different patterns. Lines were also a bit blurry.
