Living with this TV day to day, that's not my experience atall. Mine is situated with a window on a wall to the left of it, during the day the room gets sunshine streaming into it, and it always remains bright and colourfull, better than my old CRT infact.
As for the argument that blacks aren't good, well that's completely wrong too. This Samsung gives awesome performance with blacks, they are rich and deep, with an almost silk-like look. The contrast levels are supurb, superior to many Plasmas and LCDs.
Like I said, a DLP is nothing like the old style rear projectors.
Don't just take my word for it, take a look at
this review.
