I did a quick break in my break-in to watch some videos last night. Running through the essentials tuning for a quick setup before I started, I did notice the floating blacks while watching, but D-Nice's recommendation cleared it up amazingly well.
Then it was back to the break-in slides after doing a anti-IR sweep. I know it's not recommended to show anything else, but I had to get a feel for the black level and I did have it zoomed so there were no bars. Now that I'm about to leave town, it will have the next 60+ hours no interuptions.
That little taste sure looked great. The black level on this G20 is better than the G20 I returned, and equal to the S2 I returned, but oddly not the first S2 I returned. I don't have a meter, just some good eyes and the shared opinions of others, not all these Viera's are equal. This is my 4th Viera in 3 weeks and I'm happy to say I am keeping this one, but they were not all equal.
First S2 - Seemed to have a great black level and very uniform phosphors when viewing the anti-IR sweep. The only reason I returned it was I wanted to try the G20 thinking it would have a drastically better black level.
First G20 - Instantly annoyingly higher black level but very uniform look in Anti-IR sweep. Even after break-in the black level was just too much, and had a gray look to it that drove me nuts. Returned after a week of being annoyed whenever I looked at the TV.
Second S2 - Good black level, but not quite as good as the first S2. Horrible view in anti-IR sweep, hard bright and dark spots as well as a large redish area capable of being seen in break-in slides if you knew where to look. Didn't even keep this one long enough to break-in and the guy at the store agreed it was defective.
Second G20 - Black level seems lower than first G20, more on par with the second S2. No wierd colors in the anti-IR and break-in has been going for 30 hours with one full screen content break to appraise black level. Did not experience annoyance with black level like I did with first G20.
I know I don't have a meter, so these are just opinions. I do have a pitch-black viewing enviorment even during the day. This TV will probably never see the sun.
