only a little DSE noticed on Game of Thrones
So I take it you don't see the dirty screen effect when watching sport, especially football?
It's useful to get the views of someone that's owned the TV for a while. A year's certainly long enough for the TV to settle in. I'd be surprised if things change much (if at all) with your GT50 from this point onward.
I'd love to think the problem I'm having would vanish, or at least diminish, as the TV ages.
If you only see any problem with Game of Thrones, I reckon you've got a good set. I've read elsewhere about problems with this show, which many attribute to the broadcast rather than television.
What irritates me most is that the TV is genuinely excellent, apart from this one problem.

why two lots of settings? (Normal and pro).....is one better or is it s preference? And I take it that the big numbers are clicks up from zero?
will try these later to see how my second set looks...faces are all a bit odd at the moment and its seems a bit jerky, none of which I picked up on the first set....
The Normal preset has higher dynamic contrast than Professional (deeper blacks and no cap on peak white output). However, it only allows two point greyscale calibration (the white balance settings) and does not allow full colour management.
The Professional preset has a luminance cap and double the MLL (black level) of the Normal/Cinema/THX Cinema presets. In other words, blacks aren't as black and the picture isn't as bright. However, the Professional modes allow extensive adjustment of primary and secondary colours, meaning it's possible to dial greyscale and colours in more accurately than on any other GT50 preset.
As you say, it's a matter of preference.
Option 1: Go for higher contrast and slightly less accurate colours using the Normal preset (which also has in a noisier picture with more dithering).
Option 2: Go for the (in principle)* more accurate colours and more stable picture of the Professional preset, with lower contrast as a trade off.
I prefer the more stable Professional settings; though you may feel differently. One other thing, the Professional settings may help with buzzing, as the panel isn't being driven as hard to produce searing whites.
* I say in principle because these settings are taken from other calibration reports. The only way to check is by using a meter or hiring a professional calibrator. I'm working on the basis that there's some consistency from GT50 to GT50.
Strapped, is it the case that your eyes are more sensitive at picking DSE up while others' aren't? Or you found it because you were carefully looking for it, and once you see it, it will obviously bother you?

I couldn't say whether I have DSE sensitive eyes. I have generally good eyesight. I don't wear glasses; and I was told my eyesight's fine when checked last year.
I'm absolutely certain I would have spotted the vertical bands on all three TVs without prior knowledge. It might have taken a while, as they don't show up on all content. The effect isn't subtle, however, and became more prominent on my previous two GT50s after roughly 150-200 hours use.
Some may see the effect and not be bothered by it. Clearly it bothers me quite a bit, perhaps because my last TV (V20) had a perfectly uniform screen.
What's most frustrating is that I can see how great a TV this would be, if not for this one problem. Using the Professional settings* posted at the start of this thread, the picture is stunning. In fact the picture looks so good that I feel like celebrating; then the dirty screen effect shows up to spoil the party.
*I'm not naive enough to think copying settings will give me perfect greyscale and colour, but to my eyes this is a substantial improvement over the out of the box settings.
Thanks for the reply strapped, really helpful!
I definitely have sensitive hearing, so I guess I'm in need of the quietest end of the GT50 buzz I can find.....or, if the GT60 is the same, I can look at some sound damping actions as a last resort as it seems Sony won't be doing a 50' LCD....
Nick, if you're thinking about switching the GT50 out for a new model, you should seriously look into the Samsung 51F8500.
I'm eagerly anticipating this TV's launch during the next few weeks.
Asked in JL today about the PS51F8500, but they had no idea if they would be stocking it, let alone the price.

Hi Strapped, found something on the GT60, thought you might like to read it:
Main AV Setup: Panasonic 50VT65 TV, Pioneer Bdp-lx71, Pioneer Vsx-lx70, B&W FPM Series, B&W PV1, Optimum AV300 AV Stand, QED Silver Anniversary XT Speaker Cable & Chord Silver Plus HDMI Cables. Gadgets: iPad Air & iPhone 4S.
Thanks BBB. Guess we'll have to wait and see.
Did you ask about your GT50, where you stand, and what options are available?
I'm sure the GT60 will pump out a decent picture; the real question is whether the GT60 is free of the problems I and others experienced with 2012 Panasonic plasmas.
My uncertainty about this is what gives me pause. Oh, and the general buzz about the F8500, which may rival the ZT65 at a much lower price. Unlike the ZT65, the F8500 is available in a smaller screen size (51"), so I thought you might be interested, too.
No probs. I will check the Samsung out, I am a bit of a Panasonic fanboy at present though. I am not a fan of grey TVs either, I definitely have to have a black one. Where would you buy it from? John Lewis don't seem to stock Samsung plasmas.
Well, I liked the V20's gun metal grey frame, looked really classy. I appreciate some have an issue with the F8500's styling, but I'm a fan of its industrial looks.
Plus, if you like blacks, and Samsung's claim of "eight times the black expression" of their previous plasma televisions hold true, this works out at a Kuro beating 0.0025cd/m2 (compared with the GT50's 0.01 cd/m2).
With the potential to "go as bright as LED" televisions, the F8500's dynamic contrast could be staggering. We'll have to see whether these claims hold true.
In addition, the F8500 is a ZT (rather than ST/GT/VT) rival, but a 51" will cost roughly half the price of the ZT65, which is too big for my living room (and yours, based on what you've said before). The F8500 could be the best value television this year.
I'm really hoping John Lewis will stock the F8500. I'm technically within my rights to request a refund. I don't want to do this, as my experience with John Lewis has been fantastic, while my experience with Panasonic this year has been consistently disappointing.
What are the size options for this Samsung please?
