Does your 2011 Samsung "D" plasma have brightness pops? - Page 27

No did not use any test disc I used the settings from Zoyd on the calibration thread and the TV looks great. I have the Dark Knight on dvd not blu ray so I am not able to test that opening scene either.

But I do have these blu rays: Avatar, Fifth Element, Inception, the Town, the devils double, star trek, shrek 3d, megamind 3d, captain america 3d, xmen first class, the last two harry potter movies 3d, rio 3d, piranha 3d, sanctum 3d, as well as those discovery channel and history channel 3d movies. Never seen any brightness pops on these. If you know of a certain scene in these movies I will be happy to check. Raining outside and I will be watching TV all day

This seems to be the case. The 59/64" models don't have the problem in Cinema Smooth either - that seems to be due to how the black levels rise (to levels similar as the 51"). I strongly believe the fluctuating brightness problem exists because the larger sized models cannot hold or handle the lower MLLs very well or consistently. Remember, this was a problem with the previous Panasonics and in those models the blacks would actually rise over time, as well. What I am getting at is, holding fairly low blacks or mll has been an issue with plasma in general the last few years, however, Panasonic seems to have largely fixed the fb and rising blacks this year. Samsung really needs to fix fb for 2012. Let's see if they do.

I've had a PN51D8000 for a couple of months and have never seen any brightness pops until today when I viewed some hockey. They were there all right and certainly annoying. So then I went into the man cave and put the same match on my Mitsubishi L75-A94 LaserVue DLP - same damn thing. What the......???????? Then I turned on the Comcast Guide on both sets so that the hockey game was only present in about 15-20% of the total screen. Yep, still got the brightness pops on both sets, but only in the area of the screen containing the content. What the???????????

I know it's not exactly the scientific method, but the pops are probably camera or network related.

And it doesn't buzz either. And it calibrates beautifully. And the black level could be better but that's okay. And the color decoder is a teensy bit off decoding red.

9 out of 10 - wonderful TV

I bought the Wal-Mart Black Friday $400 43" plasma, model PN43d430. It, too, has the brightness pops. Seems a little less in dynamic mode, but it's still there.

Hockey was discussed many times here. Forget hockey when you read/write/think about /look for/ "brightness pops"!
Those flashes during hockey should be there. But it doesn't mean your TV is free from the brightness issues (it theoretically can be but improbable).

Why?

Because I see the exact same effect on my 30 yr. old 19" crt. It's camera flashes and/or jumbotron reflections off the ice.

Just out of curiosity I checked my slingbox streaming a hockey game to my macbook pro and "brightness pops" are just as evident. So if you don't see these on your display (any brand) during hockey games then they are below your NT (noticeability threshold).

I'm not sure if I'm being trolled by a Wikipedia defacer, but according to this:
http://en.wikipedia.org/wiki/Plasma_display


So, the further away from sea-level you are, the more your plasma will buzz?

Perhaps my display is a freak then. All plasmas unfortunately are protected by design but I have yet to see anything annoying. Caveat - I've always been lucky.

It shouldn't be optimized for sea level because the ground level is usually higher than sea level (and it counts as +/-).

I encountered a very loud 42G20 and a silent 50VT30 in the same city where there is very little relative altitude difference (Budapest).

Try this.
You don't even need a sensor to see the black level fluctuation on the marked black area. And you will see some interesting gamma fluctuations on the gray-scale bars if you play the video.
(This is the "Dynamic Contrast" video from the AVSHD709 Test Disc)

I'd like to see buzz's confirmation of this also (my measurements here) While the effect is measurable with this particular pattern, I have not seen it during any source material.

lol

I don't have to click the link as I used AVSHD for a long time before getting a signal generator, and yes, I've seen it on the D8000. The point is that I don't see this fluctuation while viewing normal content and I'm quite critical. BTW, the pattern does the same thing on my LaserVue and I don't see anything viewing content on that one either. It's not my eyes (20/10) so maybe it's the way my brain perceives....

janos is not talking about the gamma shifts with APL, it's the video black rise with APL that is the issue. Are you saying you see this on the D8000 and the LaserVue? If you put a probe on the 0% stim area of the pattern it will rise ~0.1 cd/m^2 as the APL goes from black to above black.

I probably shouldn't have mentioned the LaserView as light does funny things inside that box. I can measure 0% with a thin strip of above black on the far left side and get .007fL. When I reduce brightness a tad to clip the strip out of the picture it measures .003. I hadn't even thought about doing this on a plasma but I think I will after Wisconsin kicks Michigan State's butt later on tonight.

amen to that! (milwaukee boy and UW grad here)

Strangely, ever since reading this thread for the first time, I've begun noticing FBr in my own goddamn household light fixtures! It's a conspiracy, I tell ya!

LOL funny how much one starts paying attention to all of the electronic things around them when they get such a delicate flower as this here Sammy.

Funny how few things cost >$1,000.

I've had my PN51D550 since thursday and I've been watching various video sources in multiple resolutions and haven't noticed and brightness pops. I run in movie mode all the time and have every "auto" adjust feature and eco sensor turned off.

Any updates? Did it help with gamma shifting/ flucuating brightness?


Why did you start to regret it? What did you see?


I got an update prompt as well but didn't install (1014 for 59D6500). After Janos brought to light the EU issues with FW updates...well I don't want any regrets either. But since you both upgraded what are your opinions?

Sloppiest defense for a Rose Bowl bound team ever. They don't deserve it.

If you remember the alumni mag from a year or two ago with the picture of the water ballooners, I'm the shooter.

I like to pretend like it has helped, but the FBr is still there. It might have helped though, because I remember after updating and finishing my Uncharted 3 online session, I watched an episode of House (which is prone to having a lot of FBr for some reason). I thought about it for a bit, and realized after twenty minutes that I had not seen any FBr.

I felt like they might have gotten rid of it so then I went back to a scene in an episode where I definitely recall some FBr, and noticed that there were still some pops. I don't know if it was as frequent, but I figured if they were going to fix it, it would be all or nothing. Maybe not, though. Maybe they're working on reducing it a bit.

Since installing, I've watched three movies: Hanna, Scream 4, and Gone Baby Gone. All of them have had FBr at some points, but the letterbox content, as always, was less apparent. The FBr isn't super annoying for me if it happens once a scene, but if it happens five times in three camera cuts, I practically sweat of embarrassment that I have a defunct television or something.

It's the buzzing that kills me, though. I've done things to reduce it, and outside of movies it truly is a non-issue for me. I need to work on it for movies, though.

And ZT, I think he was saying he started to regret it because they took down the update on Facebook or something, almost as if if it was a mistake that they ever had it up.

Agreed, the tackling was awful. Also, a couple of very bad penalties on that last drive, they were lucky. Sorry I missed that issue of the mag.!

I most certainly have the brightness pops on my 51" AND 59" I also have a slight buzz on the 51" which I can't really hear from viewing distance and a louder buzz on the 59" which I can certainly hear from the same distance in VERY quiet scenes or when using the screen as a computer monitor (silent in the room.)

I've had the PN51D6500 for a little over a week now. Probably have less than 5 hours on the set so far. I haven't seen any brightness pops, no FBr issue, no buzzing, and it only gets moderately warm. Very happy with the set so far.

I'm on my 2nd pn59d7000. Both exhibited brightness pops. Particularly noticeable when watching Boardwalk Empire and any movie on BlueRay.

Other than that, the TV is a solid performer.

Now I'm debating exchanging for Panasonic VT30 or possibly Sony LED with local dimming. Both will be more money.

Just bought a PN59D6500DF from Newegg. Hope I won't have any issues but we shall see

Is the PN59D6500 worth the grand ole figure tonight at the egg (worth putting up with pops during hockey games)? That seems like the best deal we've seen all year for a large screen set at SD.net. I spent most of last weekend demoing all the 59-60" plasma sets in Sears and BB, and Samsung by far had the best pq after tweaking the sets. Panasonic looked washed out. LG was better, but didn't have the contrast or dynamics. Zenith was just a low end LG - not bad for the price, but not great. Over the years, all sets have their quirks. What's maddening about these forums is that owners seem to pay more attention to the few negatives of a set, and it takes over their enjoyment of the positives. It's like the two dead pixels you notice on day 1 of your set. They are impossible to see outside of 24", but you know they are there, and you're constantly looking for them. If you didn't know any better, would you notice? Do your wife and kids notice these pops without you asking them?

I came here right after ordering the exact same deal. I hope they do not cancel our orders.

I've had my 64D8000 for a month now. I haven't noticed any FBr. Every day I put my ears close to the tv and there is absolutely no buzzing whatsoever. I know my ears can hear clearly because I'm a court reporter and I have to "hear" for my livelihood. Only annoying thing I have all of a sudden is my Onkyo switches source from Cable TV to TV/DVD 30 seconds after I put it on. I'm very happy with my purchase, though I know I will have to get it calibrated in the near future but I'm too broke at this time being the holidays and all.
