First post and tried to do a search. No luck. I own the above mentioned tv and I was at the store screwing around with the same model and noticed that in the picture setting they have a black level option. Mine doesn't have that and also my tv doesn't allow for hdmi black level adjustments even though I have both my DVD and cable box hooked up via HDMI!
So in order to avoid the grey wash out issue that the tv has I have to reduce the gamma to -3. But as I searched the forum I found out that people are using the black level option to deal with this issue.
Thanks for your help.
