The TV will automatically adjust the input down to 720p.

As far as the dimness is concerned. I am breaking mine in... even though Samsung says you don't have to... whatever, no sense testing them.

Anyway, you'll get used to it. I crank mine up every now and again for different things... like the last UFC and video games and shit. For burn in, you just don't want to leave it like that for hours and hours on end... like permanently setting it that way. Of course Samsung tells you there's no need for break-in, so YMMV.

agree
plasma is losing a lot of ground in the tv market. not to mention the burn in you will get playing xbox. the brighter it is, the quicker the burn in. if you play the same game all the time, you will get it. LEDs wont.

From what I've read, with pixel shifting enabled it's not really an issue. The reviews by customers on the tv I bought are top notch 4.8 out of 5.

i have heard pixel shifting can be a big help, but it also not the end all answer to screen burn in. havent seen it in person.

Well with pixel shifting at 4 4 1 I still got some image retention with the settings up high. I enabled scrolling and it's gone now, but thought I'd share. Turned settings down to break in levels again and changed pixel shifting to 2 2 2.

Lcd won't either <3 my bravia

I hve a 42" LCD in my bedroom. I do like it, but the Plasma looks noticeably better.
