With Samsung you actually have to go into the menu system and make sure the burn-in protection is turned on.
Yeah, I had it turned on. Actually had max pixel shift on (4) as well ran the total white screen, and gray shift pattern.
Also, even though I had not gotten around to calibrating, I did (out of the box) have the brightness on low, as well on full energy saver mode.
So it was funny it burned that quick.
Granted, I fell asleep with the direct TV box in the menu position last night...
Almost bought the panny, but the Samsung I got is one of the highest rated 50" plasmas in it's class for PQ.
And I will say, yes, it does have superb PQ (other than the burn-in).
No big deal, have 5 days to return 'no questions asked', and the 30 day exchange, as well the 3 year warranty.
So I will return it tomorrow, and get the 46" 1080p LCD that I was looking at (by chance another Samsung).
Or just go ahead and upgrade the projector.
But before returning, LOL, I will be putting it on torch mode and play Blade Runner.
