I purchased a TC50G20 from Best Buy on March 6th. I also purchased their new Panasonic Blue Ray player. The THX setting mode out of the box is gorgeous. But wait, there's more.. The first blue ray I viewed was the Matrix, 10th Anniversary Edition. I loved this G20 until I saw the gamma levels change 4 times during the scene when Trinity rolls down the stairway and aims her guns up at the window. I also noticed the same "lightening and darkening" of the screen while watching a scene from Pirates 3 between on the ship at night.
I can rewind and watch it over again and can see it every time. This drives me nuts. What's frustrating is that the gamma/brightness shift is not simultaneous with the scene changing: the set takes a moment to adjust to the frame in the movie. This occurs even with the CATS setting off. A darker scene in the movie with more blacks causes the set to adjust and the blacks become "darker" a few moments later. It is so obvious that I am not able to watch blue rays in the dark at this time, and I'm even considering returning the set. Call me picky, fine. But I'm not happy about this issue. After tinkering, I realized that the shift is less evident when the set is watched on the "dark" setting found in the advanced menu. Also, on the "custom mode" set up, I can set the gamma to 2.6 on the pro menu and eliminate the problem. The downside with both these settings is I lose grays and contrast. No one I've spoken with at Panasonic even knows the difference between infinite black and infinite black pro, let alone what floating blacks are, really?
My question: Is there any way to fix or lesson this change? What causes floating blacks? Is this a power issue? Is it a tech issue? What alternative do I have other than the new Panasonic 2010 Plasma line to get great blacks? Will the v-series have this issue with the infinite black "pro" panel? These are my questions. Yes, I have adjusted the brightness multiple times and no fix. Any help will be appreciated.
