like hell I'm dropping over a grand on a TV just to baby it when I never had to do any such thing for the plasma I bought SEVEN years ago...no picture quality is worth that
I don't know what percentage of these 2012 panny plasmas are problematic, I'm pretty sure it's fairly small...but for the amount of OCD screen wiping and stressing out I see from people on this and other forums, that damn TV better be able to give me a hand job if I have to give it more attention than my girlfriend
I'll report back with my findings, something tells me I won't have any issues but the lengths I see people going to borders on insanity
Well as promised I'm checking in with my 55GT50 that I've had since early January, it now has near 600 hours of use on it.
Here are some details for the record:
- TV manufacture date is December 2012
- I have it hooked up to an HTPC through which I watch TV and movies with Windows Media Center and Blu-rays (both discs and downloaded rips using Plex)
- I also play PC games through Steam and have an Xbox 360 that I play FPS games on like Halo and BF3 so there are static HUDs
- I ran NO break-in slides whatsoever nor did I zoom the picture on channels with logos or vertical bars for any period
- Contrast has never been above 80 and brightness has never been above 50
- I have wavered a few times between HD Master's and D-Nice's settings
Channels/shows that I usually watch a lot of:
- Comedy Central
- Pac 12 Network
- Fox Soccer
All of these channels have logos
These are my highly unscientific findings should anyone care.
For the first 2 months, IR with certain logos was flat out NASTY.
I would watch one basketball game on ESPN or one soccer game on Fox Soccer and those respective logos were sticking in the corner of the screen for OVER A WEEK without me going back to that channel. Granted, with moving images on the screen you couldn't really see them but anytime there was a scene with a solid color background (a lot of commercials have these), those logos were plain as day and my eyes were drawn right to them.
They were also easy to see if I was navigating around in XBOX menus since there are a lot of white or light green solid backgrounds.
Those two channels have been the worst offenders BY FAR. I don't what it is about them but nothing else sticks as bad.
I didn't bother running the screen-wipe or any other utilities because I wanted to see how quickly just normal use on other channels/games would clear it up.
I would periodically fire up D-nice's panel prep slides just to get a solid background to examine and saw almost no sign of IR from those two logos fading for nearly 2 weeks after only a couple of hours viewing. Needless to say I was fairly pissed and scared that Panasonic had royally screwed up this generation of plasmas since this was a similar experience to many people who have complained on these forums.
At this point, however, I was already outside of amazon's return window and figured we might as well see how long this set takes to REALLY settle down.
I continued normal viewing habits with the exception of very limited ESPN or Fox Soccer viewing for the sake of my own experimentation.
It took nearly a full month for those logos to be almost invisible on certain colored slides (again, this is with no screen-wipe tool or pixel flipper or any kind of utility).
If I look at the screen from certain angles and really strain I can see hints of those logos still but certainly not enough to bother me.
At this point, I still notice significant IR with channel logos or items from my computer desktop on very light backgrounds shortly after having them on screen for at least 20 minutes but they fade away just as quickly through normal viewing. I will only notice logos on solid backgrounds in commercials or slides (which I hardly bother with anymore)
To date I have notice virtually ZERO IR as a result of gaming or web browsing with this TV which is simply baffling given how bad the logos have stuck at times. It makes me wonder if certain areas of the screen are more susceptible to it although that would be very strange.
That all being said, I would have to agree with people who say that IR is most likely a worse problem with these model TV's over slightly older models in the sense that they appear to be more sensitive to it early in their lives. It definitely appears to be getting better (read, less sensitive) as it racks up more hours but the general "first 100 hours" rule quoted by a lot around here certainly turned out to be closer to 500 hours for me....and still counting.
There have definitely been times where I wondered if I should have just gone LCD for this round. Maybe I was spoiled by a previously perfect TV but the picture quality on this GT50 doesn't look leaps and bounds better than my 7 year old PX900U plasma. It's pretty and all but I'd be lying if I said the IR doesn't bug me even if it is only in the corners and only over solid backgrounds. I feel like in 2013 it's something that we shouldn't have to deal with and Panasonic certainly seemed to be less than genuine in their responses to those people who have dealt with it over the past year.
Overall I enjoy the TV and nobody else but me seems to have noticed the IR issues, I am hopeful that over the next month the issue will continue be less and less of an issue.
It will most likely be my last plasma TV judging from the news recently so this is all likely moot anyway but I figured I should share my experience.
