Has anyone seen their black levels rise on their GT50? I feel like my black levels have gotten quite a bit worse since I bought it in 2012. During dark scenes, the blacks definitely look more gray and I remember back when I first got it how amazed I was with the blacks looking almost perfectly black even with nothing on the screen.

For instance, HERE is a picture I took when I first got the TV comparing it to a Samsung e7000 I bought originally (I returned the Samsung). My GT50 now resembles how the Samsung looks in this picture.

Nope, not at all, still as black as day one. What are you displaying on your screen when you are testing? What settings are you using?

No black levels look good on my set been using HD masters night settings. Try watching supernatural on Netflix it has some of the deepest blacks on that TV show. If you have a non calibrated plasma try a system reset, I was having a problem with my Netflix app and I was told to do a factory reset by a Panasonic rep after that my Picture Quality improved and fixed my Netflix app, just FYI if your plasma is calibrated it will erase all of your settings and your Viera login info for the apps.

I dont usually display a certain image to test, it is just something I notice at times when there is a darker scene on the TV. I often notice the black levels when I'm playing music off my receiver as the screen is almost completely black with a bit of writing on it for the artist and track name. I also notice it often during the end credits of movies, with both Netlfix and DLNA.

I believe I'm still using D-Nice's settings that I originally used back in 2012, but I would have to verify that. I'll try to remember to take some pictures tonight and also check my settings.

When in a completely dark room and there is nothing on the screen, like the picture in my previous post, what does your GT50 look like? Is it basically completely black or does it look more gray like the right tv in that picture?

I have seen no reports of that with the 2012 models, the panel driving method was changed. I have seen documentation on the VT50 not rising so hard to imagine the GT50 would have that issue.

My set looks completely black in a dark room.

Well that is good to know but also sucks knowing that I'm not just imagining things. Last night I tried switching between my custom settings from D-Nice and the THX settings as I remember reading that the THX ones were supposed to give some of the deepest blacks but I saw no difference. I was unable to find my camera yesterday to take pictures, so I'll look again tonight.

How are you sure you are getting the deepest possible blacks without a calibration for your unique set ?

I can't be sure at all. I could very well get deeper blacks with a calibration specifically for my set, but I'm just comparing what I remember seeing for black level when I first bought my set vs what it looks like now using the exact same settings.

I did notice that some inputs seems to have 'noise' on the screen which made the blacks look more gray. I make sure to avoid those inputs though and just route everything through my receiver to the good input. Here is a comparison of the 'noise' between two inputs. When I took these pictures, nothing was plugged into either input.

Input 1
Input 2
