I just tranistioned from Panasonic 60" DLP TV to Samsung 530 60" Plasma TV and the degradation is stark. On the plasma using HDMI (same as DLP) its like every other pixel is turned off. for a pixelated, cross hatch feel to it.
It's really soured my excitement about this new TV. Games do look somewhat decent but desktop browsing is horrible. Any reason for this? Is it defective? Screen is at 1920x1080.

tinker with your TV settings, it should have a TV mode and a PC mode...pc mode will give you that sharpness
Make sure you turn game mode on. If you don't your mouse movements will feel like controlling a sponge.
