Extremely late to this game but Ive had this set for a few months and its been pretty sweet. I have searched everywhere and cant really find a pin point answer for the situation I have going on. I want say this is normal but I have never owned a Panasonic before and like most have had the all might Pioneer Elite 111FD for about 6 years now. Was time for an upgrade but also over the 6 years my Pioneer has developed some defects so it is hard to compare directly with a brand new display.
I have less than 300 hours on it, no calibration, plugged in DNICE settings and a few others but mostly watch in THX Cinema. I also get some pretty quick onset IR, literally I could turn on my Bolu Ray player and let it sit for 5 seconds and turn and I will see IR that lasts about 30-60 seconds. Quickly fades so its not a concern at this point thought I do read that IR can happen at any point.
The ZT60 is a magnificent display with some minor issues but very minor. Only regret I have is not getting the 65". My question is about the blacks..they are very inky and dark when there
Is 1.) light in the room 2.) when controlled lighting is at a dim setting 3.) with ambient/bias lighting. Blacks look jaw dropping in these environments.
My concern lies with the panel at night time in a completely dark room (black sheets up for now until I get curtains), not quite man cave dark but dark none the less. I would have thought with lights out blacks would be even better but they are not. They actually seem to be worse or "lighter" in a pitch black room. With blank screen playing you can easily see the panel glow.
Last night I watched Gravity for the first time, tremendous visual movie especially to test blacks in a dark room. With lights on or dimmed low the blacks looked like a black hole in space, deep inky, made the picture punch that much more.
with lights off(all in THX cinema btw) those blacks no longer look as deep. For example there is a scene where Sandra bullock is spinning out of control still attached to the destroyed satellite and before she unbuckles the blacks around her looked incredible at night, bezel blending almost. BUT once she detached and the satellite was off the screen and she was floating further into space, those black areas especially the letterbox bars became very gray colored ashy looking almost, and no longer had the deep feeling anymore. I could make out all sides of the border for the tv. Obviously with moderate to high amounts of light on a black background blacks look deep like it is with the closeup of her spinning, then when she unbuckles you see her floating out into space which leave little light on the screen and the nice big universe that was once black looks grayish black.
I understand to get true black you need OLED or FALD sets in a pitch black room to achieve no glow. But the glow I described seem normal to you? With medium to bright images on a black background it's like they are floating in mid air.
With low or very low light and low APL scenes it's like the blacks are brighter and you can distinguish the whole set with a fully dark scene with very low to no light in it.
Is this normal? If plasmas do this then I can only imagine how bad a LCD OR LED would look next to this. If I remember when my 111 was great with no defects that it also glowed a bit but I don't remember it doing it this much. I did do a reset (completely unplugging everything and replugged it in) and seemed to do a little something to the PQ overall so maybe my voltage or boards are faulty. Its a July 2013 build, so maybe its a return but I bought it from Chris at Cleveland AV (formerly Cleveland Plasma) which was at one of his other locations (extreme electronics I think was the name in PA, Im in the New England area, so I doubt very much it was used especially with Chris being sponsored by AVS and having a stellar rep. Set was pristine looking as well. and inspected fully.
Lastly I was going to invest in some proper D6500K bias lighting but I thought the purpose (especially from reviews) of this ZT was that the blacks were so good that Bias lighting seemed like it shouldn't have to be a option. Maybe my standard is to high but some help is always appreciated.
Thank You AVS
