Hi all -
I just received my 921 today and hooked it up through my DVI cable to my Samsung DLP (50" - HLN507W) DVI input. Everything seems to be fine, albeit one irritating exception:
In the far upper left corner of the broadcast, there is a 2x2 pixel-length white square that remains with any broadcast or channel, HD or SD. For reference, it has the same "look" as a Plasma TV with burnt/frozen pixels. The "white box" is ALMOST 3x3 but in all fairness, the bordering pixels are only half-filled with white giving it a slightly smaller appearance than a true 3x3 box.
Hi. I just got my 921 and Sammy HLN507 both hooked up today, and I noticed the same thing. I was only just starting to experiment to figure out what was responsible, and came to the preliminary conclusion it was the 921. I came here to see if my guess was right before experimenting further. . Glad to know I'm not alone, anyway.
