it does appear after reading some post in the 7150 owners thread that that model has some of the sets having Samsung panels. Some owners are getting some pretty bad clouding. My last Samsung set, a LNT-52a650 had some pretty noticeable clouding. That set had a Samsung panel. The positives on my AU panels are good uniformity, no clouding or flash lighting, no banding or ghosting. Negatives are average contrast and blacks and poor off axis viewing.

I'm not so sure about that. I thought the difference in panel versions from Samsung has more to do with what manufacturing cycle they are from. For example, last years UN46F6300 TS01 and TU02 panels have the exact same part number.

I queried the Sharp panel in my UE32F5000 and got the following response (after an initial reply telling me how to adjust the Sharpness setting biggrin.gif)

"I have looked into your query and I can confirm that currently Samsung only offer a 46" S-PVA Panel. Obviously as you have a 32" TV, this would not be fit for purpose.

As you feel the Sharp S-PVA Panel that you have purchased is not up to spec, I would advise you to refer back to Sharp.

I am sorry that I am unable to assist you further with your query and I hope that you find a product that is suitable for you."

(I'd since returned the TV to Amazon.)

There is so little profit in panels at 40" and < that today it's challenging to find any panel from a manufacturer that is truly high end - this is an area that has gone in reverse. I bought the highest end 2014 40" Samsung for our Master Bedroom Armoire which prevents going larger and I regret it cannot come close to my F8000, D8000 or the 5 year old Sony Z4100 it replaced.

Smallish panels (below 50") are so low profit that basically they are using old generation tech subcontract outsourced glass from China, Taiwan - they may merge Smart Tech but the panel tech is most often low end - it's harder than ever today to find a quality reference panel below 50" and even companies like Sharp will outsource the small ones as the profit margin is too low or non-existent. My 50" Panasonic Budget LCD is better than the top end 2014 40H6350 Samsung - the days of high end 32-40" LCD's appear to be gone to the point that even a Vizio in those sizes look good as they have little quality competition in those sizes as there's so little money to be made. There's no reference quality in small LCD's.biggrin.gif

I'm not sure what reference quality is. "Good"?

I'm not convinced Samsung don't actually make a 32'' panel, since people seem to believe they have them and HDTVtest thought they reviewed one. I just thought their reply might be of interest.

Therefore Panelook is a dead end. Hence the other listed methodology is to go by what others have designated. In this case (Version Numbers) ie UD02 is Samsung according to NSXFAN.
I will speak for him and say that that is a best guess as all of us here are not experts in the field of panel design, yet we are disseminating information from multiple sources to make an educated guess.

I would not bet my set is Samsung even tho Panelook says it is, moreover that this macro I took shows the pixel pattern.

How about an US03 panel that came in some F6800? Is it S-PVA by Samsung?

Looking through reviews of last Samsung TV - PSA is everywhere. Contrast and black level are so so. So what kind of S -PVA are you talking about? To get real information about panel type you have to look into servise menu at least and more correctly - get a pixel shape.

Not sure what you are talking about. S-PVA is the type of panel they use. AU Optronics uses type of MVA panel called A MVA. Also thought this was so typical of Samsung. I posted a less then stellar review on the Samsung site citing the panel lottery. They review was accepted but today it has been removed. Now all 5 reviews have 5 stars. Classic!

Thanx for the answer. I just want to make sure the panel in the F6800 is Samsung, because I've read some ugly things about the other panels (they can't handle the motion very well, the blacks aren't so deep, less PQ in general, etc).

PSA ((Polymer sustained alignment) is a new form of PVA panel from Samsung. For example http://www.digitalversus.com/tv-television/samsung-ue55f7000-p15536/test.html#full-review

Thanks for the link. Very interesting. Seems like Samsung has taken a step back with this new form of PVA. Wonder how my AMVA panels stacks up to it. Thanks again and very informative. That is the site that had many articles on the whole panel lottery and even did a head to head Samsung vs AUO panel in the same set. Got the attention of Samsung executives who requested better measurement instrumentation. Since then not a peep from digitalversus about the whole panel. Wonder if Samsung threatened litigation or just greased them to stay quiet.

After some research I found this AU site with all 65" panel models in production. CR ratios look good as well as brightness and response time. The plot thickens a bit! http://www.panelook.com/bramodlist.php?order=panel_id&by=desc&brands[]=AUO&panel_size_inch=65&production_state=1

I just brought home the 60" from Best Buy a couple nights ago. Not impressed out of the box and am considering returning it.

Flashlighting in all four corners is the worst problem. Definitely noticeable at boot-up, but more importantly during darker scenes in the only Blu-ray I've watched so far.

Black levels in general are poor, but I can surely improve with tweaks. I'm coming off a SFP 36" Trinitron tube so I'm spoiled for blacks.

I have an HH01 which maybe is the only panel for 60"? Even though I remembered when I bought my mom a 32" Samsung TV a couple years ago -- and made sure to find a TS one -- I totally forgot about the panel thing when I bought this. Might be worth going down to 55" for the Samsung panel alone.

I use a 2560x1440 Samsung LED monitor (with SS01 Samsung panel), and was absolutely in love out of the box. The thing is damn near perfect. Was hoping for the same experience with the TV, but no such luck...

Damn, I hate returning/exchanging stuff. But I hate being bothered by obvious PQ issues for years to come even more. No guarantee the 55" will be better, but I haven't read about flashlighting in that size.

Right there with you... I returned 3 Sonys 47W802A, finally gave up and asked for the money. Going for Samsung, but there's no guarantee at all.

Woops. Still mostly applies, but I actually thought I was in the 7150 owner's thread. Will re-post comment there.

I was troubled that they all say 60hz but one... And it's a 4k screen.

All our sets are 60hz native. The set doubles that by adding a extra line.

I was under the impression they were 120 Hz native. Interesting.

I know about backlight scannng tricks to claim a higher refresh rate. Maybe I dont undertand your terminology, What do you mean by "extra line"?

Yeah I thought the same thing until a few months when I bought a used PS3 24" set for my son. He is a big on line gamer. He set his video card to send a 120hz signal to the set. It would not work. All he could send was a 60hz signal. Called Sony and they state that the set doubles the lines of a 60hz signal. She then said the 240hz sets quadruple the signal. So I think AUO is just being honest on the actual native refresh rate. It is confusing to me. A few years back you would see 60hz on the back sticker on the 120hz sets. It would get people upset and confused. On my 6350 there is nothing listed except where it was made, energy info, mode and serial number and version number.

I got the UN40F6350 this weekend (Amazon) and won the "lottery," as well.  The panel version is a TS01 and I've confirmed it's an "A" panel in the Service Menu, too. 

I'd gone through and grabbed people's recommendations for their panel's configuration(s), as many people had mentioned they needed to do quite a bit of modification of the configuration settings, out of the box, to get the image to look "decent."  Oddly enough, the only thing I had to do was to kill the Eco-Sensor and, per another user's post, I turned the Sharpness down to zero - that last one actually did make a rather noticeable difference on my 40" so I did the same on my older 55" (UN55D6050) - big difference, as well.

 

I'm very surprised that Samsung has outsourced their panels.  I always did hold them in such high regard as being a cut above the "lower-level" manufacturers like LG, Sansui and Sharp.  This reminds me of when IBM started outsourcing their harddrives to Hitachi but the IBM logo remained stamped on the drive.  At first, things were "okay."  But after awhile, there was a veritable landslide of failing drives and they were all the Hitachi drives.  IBM finally forced Hitachi to start labeling their drives as Hitachi drives and no longer showed IBM's logo (nice black eye for IBM, there!).  I suspect something along these lines will have to happen for Samsung to stand-up and take notice...and hopefully bring panel manufacturing back in-house.

LG is a "lower level" mfr? Really? Do you think Vizio is a better mfr than LG? Outsourcing panel types is actually very common for any mfr, even LG, who is one of the few remaining tv mfrs than makes their own panels (Samsung being another one). Mfrs don't have the capabilities or economic drive to make their own panels in any size they choose, hence outsourcing. Besides, the bulk of consumers don't care what panel they have as long as it looks good to them. Keep in mind that there a lot of consumers who love the torch mode look eek.gif Not everyone is as anal about their tv's as we are here on AVS.

I think the poster above who mentioned that 60Hz sets adding an extra line was referring to motion interpolation. When motion interpolation is turned on a 60Hz set, an extra line is inserted to mimic a 120Hz frame rate (60fps x 2 = 120fps).

Yes.  I do consider Vizio to be a "low level" manufacturer, as well as LG, Magnavox and a myriad of others spanning several types of electronics for both the home and car.  Thanks to a stellar marketing blitz, most people think LG means "Life's Good."  It actually means "Lucky Goldstar."  This is actually a happy coincidence (most people know of the merger between two different companies of those same names, Lucky and Goldstar, that formed LG), it's not at all too far from the truth - they got lucky...very lucky.  Many of us, who are older, remember Goldstar from the 1980's, and their horrific line of subpar electronics.  It was only about a decade after they appeared on the market that Goldstar almost went belly-up and lost everything.  That merger was a very welcome, and much needed, second financial breath.  However, from what I've seen - washed out images, prematurely failing units (TV's, microwaves, dishwashers, etc.) - they haven't improved much if at all.  

While Vizio did actually take the award for best TV, several years back, they couldn't hold on to that accolade. The way I see it, even a blind squirrel finds a nut.  If they were truly a top contender, like Samsung, LG could have easily held on to that prestige and given the market titans a run for their customer-base.  Samsung continues to dominate the market, as does the upper-line Sony units, despite Samsung sub'ing out their panels and slapping their name on them, allowing that prestigious reputation to sell sets for them.

And speaking of unscrupulous practices:  "In November 2013, it was discovered that some of LG's smart TVs silently collect filenames from attached USB storage devices and attempt to send them back to LG's own servers, although as of this writing the web application does not exist and the purpose of this is unknown. The same television was also found to send program viewing data to another LG-affiliated server which is in operation. Shortly after this blog entry went live, LG disabled playback on its site of the video explaining how their viewer analytics work and closed the Brightcove account the video was hosted on. By December 2013 the page itself was removed from LG's website." (Taken from LG Electronics wiki)
