No crushed blacks here either. Set the tv up properly instead of expecting it to look perfect out of the box and enjoy the console. The sharpening level and hdmi blacks both had to be lowered for a more natural picture.
I'll give it a whirl tonight and see if it makes any difference. Granted my TV is 2 years old but at the time it was voted one of the best for gaming and was pretty much top of the range but I have left stuff as "default." Will give it a try
