Was having worse issues when running the set through a power conditioner. Now with direct power, its a better situation. However, a line in the center of the screen and mild banding on panning scenes still exist.

I went through 3 900a as well. All three had noticeable banding dead pixels and clouding. First had dust behind the glass. I don't know who they have running there Mexico plant perhaps monkeys... I really hope the 950 is better.

Yes, I think there was this super smart chimp who was in a science project and then there was a virus or something and then Gary Oldman got involved and started yelling into his HTC phone. It's all in the trailer (I think they show it about 75 thousand times during sporting events.) Btw, I don't know who does your spell checking, perhaps monkeys...

I'm curious if you, and the nsa while monitoring people through there tv camera's and cell phones aren't zapping the part of they're brains that controls the proper use of there, their, and they're? Curiously it seems to have been destroyed in a significant, and growing part of the population. I've noticed this phenomena on numerous forums. People just can't seem to get a grip on they're use of there, their, and they're. I've noticed this over their at the avforums as well. I'm not sure what's happened to there language center in they're brains, but for some reason a lot of people just don't seem to know how to use the word.

Sorry to hijack the thread with a somewhat serious question but. Who is supplying the panels for the sets to be tested? Do you anticipate that the panel itself will have much of a factor based on past experience? Thank you.

That would differ per manufacturer and per set size on top of other circumstances. Its probably best to wait to have Chad do his reviews and you can request that he attempt to find the maker of the panel of the sets he sees.

I'm not sure I understand your answer. I thought we knew exactly the manufacture and set size from at least the 4K LED/LCD sets listed. What other circumstances are you referring to? I just thought that by now someone like perhaps Chris, could find out who's panels are being used and if that brand is considered to have a better track record than their competition.

You asked about what panels, usually that is something you can only know once you have the set and can inspect it. The panel can differ from set to set (see posts on panel lottery). Companies source their panels usually from an outside source.

If you are referring to the sets that will be part of the "shootout" then all one would have to do is see the 1st post as all are listed.

As far as track record goes most of the majors are all the same as far as numbers go. Reliability is always a crapshoot, you
Could buy the most highly reliable TV and still get a bad egg. Sony, Samsung, Panasonic, etc last i checked were all within a percentage point or few.

So you're saying that if I buy a 65x900a it could have a A-MVA panel from AU or a S-PVA panel from Samsung or a S-MVA panel from Chi Mei?

Seriously. Lets not give opinions to much credit. This forum will suffer terribly if everyone became "opinionated > scientific facts " minded...

This is an opinion for an opinionated individual it seems. Not a fact. Both are virtues which do not fair in a SCIENTIFIC audio and visual forum. But hey whatever floats your boat.....just dont tell us you feel excluded from this scientific community bc no one is taking your comments or "opinions" seriously....just sayin'

ps: Dont forget the name of this thread is "4K analysis by Chad B"
You sure like to throw around the word "scientific" a lot. What are you talking about exactly? Are you referring to technology that went into building the devices? Electronics? Physics? Psychology of perception? Image standards such as NTSC?

Speaking of NTSC standard, how do you think it came about? Was there some universal "scientific" fact that dictated the standard? Or do you think it was arbitrary standard that came about from the limitations of technology of the time?

If you knew anything about science, you'd know that one can argue that "facts" are nothing more than yet undisproved opinions. And what is "this scientific community" that you speak of? Are you a scientist? Are we all engineers and scientists now? Let's not flatter ourselves. We are hobbyists and enthusiasts. Nothing more.

FYI, in terms of resolution, 4K is better than 1080p. So if your criteria of "looking better" is resolution then, yes, 4K does look better. That is not an opinion. 4K > 2K.

Technically yes, you probably want to head over to the sets dedicated thread to see if they have determined the source or sources of the panels being used. Samsung is notorious for using different manufacturers for their TVs even within the same size. You're better served in the owners threads however if you are looking for a specific panel. From a quick google search I found that the x900a could be an AUO panel, but that's unconfirmed as far as my quick search found......

No no, the 900a uses a AUO panel same as this years but a slightly different version. I think for the most they are the same panel regardless of the size this year, last year I believe the 55 inch did use a different panel as the 3d was not full res. Another reason why 4k sets are so expensive is shortage of panels... this year is better and next year there will surely be more manufactures and thus cost will be cheaper.

If you were in the market for a new 4K TV how important to you would the panel manufacturer be? I mean, if Chad comes up with a clear winner would not that finding change with a different panel? In the end, does it even matter who is chosen as best if you have no assurance that your actual TV would have the same panel that Chad tested?

Not much really, more important would be the TV manufacturer... as long as you know the panel type that's all that really matters.

Wait so what I said at the end was wrong? The beginning of my answer was a broad one to give an example of what could happen. I then found that Sony uses a 10-bit AUO panel supposedly (have not seen confirmation.

It has a lot to do with it, I've talk about dedicated 20 amps line a few times on Avs forum and what power outlets to buy, I have two Plasma TV's in my house they both are similar and you can see the difference, my brother and all my friends can see and hear difference with audio and video and guess what you don't have to believe me that's why I have not brought 4k tv my two BB friends told me I don't need change anything else.

The 950 might be a little better than the 900B, I would rather have 3k for a rainy day
IMO the most credible reviewer has given the Sony 900B the best picture of any 4K TV. If I was on the fence the cnet review would be enough for me to go 900B. Cnet has them all side by side set up properly and no what to look for.

Congrats to all the 900B owners.

I wouldn't put to much weight behind his reviews. He has plainly stated many times that 4K is stupid and he can not see a difference between 1080p and 4K at their recommend viewing distances.

Also I think everyone, and not just him, that review sets need to stop putting this in there reviews.

"performed a hands-on evaluation of the 65-inch XBR-65X900B, but this review also applies to the other screen sizes in the series."

This is simply no longer the case, as many manufactures use differently sourced panels for difference sizes in the same line. European reviews seem to open up the backs of the TV to identify certain components and I think this is a feature the US reviewers should start to follow.

Could not agree more with your last sentence. This panel lottery should be made a bigger deal in reviews. If you and I buy the same TV do we have the same panel?

Especially when the reviewers are getting samples provided by the manufacturer. You can guarantee they're getting the best of the possible panels, or perhaps even a panel that's not in the sets that ship to the public.
