Official Samsung 2011 PNxxD550 Thread - Page 26

post #751 of 1918
I posted this in the brightness pops thread and figured i would here as well. I have the 51D550 and I don't think the set will display RGB color space properly. If you hook your Xbox or ps3 up and set them to display in there proper modes ( expanded for xbox and rgb full for ps3 ) you should be able to get the best picture quality. But what happens is you will end up with crushed blacks. This is with your HDMI black level set to low in picture options which should give you the correct reference levels for RGB. I believe normal is for Video playback and is greyed out when playing blu rays and other video sources that aren't native RGB. When watching Blu rays and DVD's I get no black crush.

Now I can change my HDMI black level to normal while playing a game but the picture looks all washed out and greyish and lacks the detail of the low setting.

The TV has a great picture but these problems are really killing me. I don't know if I should call Samsung or if they could even help. I've owned my set for about 2 1/2 weeks and don't want to return it for another brand but with the pops, crushed black problems and no resolution in sight I might have to.

HDMI black:
Normal - Full Range RGB (correctly processed)
Low - Limited Range RGB (buggy -> properly clipped blacks but incorrectly clipped whites)
This option is disabled with YCC signals (shows Normal in gray) and seems to be correct (but I don't have any real YCC devices to say it for sure).

RGB reproduction:
Only PC mode (with Standard and Entertainment picture presets) reproduces the RGB 4:4:4 (and may be YCC 4:4:4, I couldn't test it properly) signals without an intermediate YCC 4:2:2 chroma sub-sampling.
Normal (where you find Movie, Standard and Dynamic) and Game mode (locked to Standard) modes will convert the RGB signal back to YCC 4:2:2 for processing which is noticeable on some image contents.

But PC mode will only activate with signals like 720/1080 p/i 30.000/60.000 Hz, display modes like 1080p23, 1080p25 or 1080p29 will automatically trigger the normal YCC mode.

The controls are very limited in RGB mode. There is no Color Space option or CinemaSmooth. That's why it could bypass the YCC processing stages.

Loosing CMS is OK (you can do it with your PC) but CinemaSmoth was a notable reason to buy this TV.

why when I turn my new Samsung plasma PN51D550C1F on, it displays 1920x1080i 60Hz in the upper right hand corner, why not 1920x1080p 600Hz

thank you

OK so I have to use pc mode to get correct RGB reproduction? I have tried using input 1 which is the dvi/hdmi input in PC mode and found that it still looked the same. If I set my HDMI level to normal it looks washed out, and on low it looks better but crushed blacks. If normal is full range RGB then why when watching YCC content does it grey out HDMI black level and leave it on normal? Or is normal the correct setting no matter what? I have no problem with the picture in DVD or blu ray play back just games.

If I set my TV up as described for optimal RGB reproduction do you have any suggestion on what the contrast and brightness should be set at?

That's the incoming signal information. Output is 1080p

As Roland was saying above, That is your input source. When you connect a device that outputs 1080 like a PS3 or a Bluray Player it will say 1920x1080P 60Hz or 24Hz depending on the source material. The TV itself is always displaying 1920x1080 Pixels because that is how many it has.

My Satelite Receiver only outputs 1080i most of the time unless I want to buy a 1080P PPV movie. So I only see 1920x1080i 60Hz in the upper right corner when I'm watching TV.

The 600Hz is what its called Subfield Motion. It takes the 60Hz source frame and flashes it on and off 10 times making it seem like 600Hz. It's mainly a marketing thing.

3. I don't like Panasonic for TVs ( its a brand perception thing almost like buying a dodge or chevy automobile...yuck)

4. My picture quality is awesome and I have great blacks with this set.

5. 70% of my viewing is Blu Ray and I have Cinema Smooth on which prevents the pops (this is the case for me. I know exactly what they look like and they only happen while watching cable)

I will hope for a firmware update, but if not I got a wonderful price for a wonderful Plasma.

So are these brightness pops pretty much a definite thing?

Or is this one of those things where some people say their TV doesn't have it?

My calibrated contrast/brightness settings are very close to the default values.

Most of the evil features are disabled (and unavailable) in PC mode, so I don't know what may causes it.

You should try to set up the contrast/brightness settings with the "APL clipping" test video. You can find it here by searching "AVS HD 709".

Sharpness is good to keep at 50 in PC mode. I keep it at 18 for the Movie mode. This mode isn't that bad for RGB signals either, but it isn't as sharp as the PC mode.


Don't let the names to confuse you. In the RGB world Full Range is more usual, and Limited is more often in the YCC world.

The Low setting is broken anyway, it doesn't good for either Limited or Full Range RGB. Normal is good for Full Range RGB.

hello i just buy my new tv on sears mexico and i have to say.......this tv has a great hd reproduction whit a good color, nice 3d, but the black levels are not soo great, my last tv whas one panasonic tc-p50x1 which is not a 1080p model but it have a really good black level performance, well that tv was calibrated whit the D-nice settings and may be we can talk whit him and see all the aspect for calibration.....

Got my set yesterday. In love with it. Then it started turning off and on automatically every 30 seconds. :-((( Back it goes for a replacement.

That sux sorry to hear that I know what that's like. Brining my set back sat
post #762 of 1918
hi a few months ago I saw a ps59d550 and I think it looked okay. It had what appeared to be not that great blacks and not that bright and slightly washed out colours even in dynamic mode. And then recently I saw a ps51d7000 and it looked very nice. Bright with plenty of pop and bright whites. And the 59" versions of the d7000 and d8000 seem to get great reviews with dark blacks.

What I was wondering is: The d550 I saw, was it in Eco-mode or something or does it look a lot less contrasty than the d7000/d8000? Can you make it look similiar to the d7000 with the right settings? And the d550 in 59" has considerably lighter blacks in a dark room ? Very curious. Has it been measured? The thing is, the d550 has grrrreat price........ and I would love to get a new TV-set fairly soon. :-)
cheers
post #763 of 1918
You can hack it to get the 10pt Cali and get amazing picture quality out of it. There is a thread on here all about it. Look for it. D550 unlock

post #765 of 1918
Bought a PN59D550 for my birthday last Saturday...

Love the set so far (upgraded from 42" Viewsonic LCD), but I get noticable buzz...

TV is mounted on a TV stand, buzz seems directional (ie. you can hear very clearly 12-15' away when sitting dead in-front of the TV)...

The buzz is not noticable over movie/game sounds...

Is this considered normal plasma buzz, or should I be concerned and consider returning the set?

My wife says to be happy with what I have and live with it, but I feel like it degrades the ambiance of quiet scenes in movies...

No brightness shifts noticed yet (thank goodness!)
post #766 of 1918
thanks a lot blwn I will check it out. I wish someone would post pictures of the d550 and d7000 side by side with optimal settings.. :-)
Or I wish I could go into a store and hack it, and nobody would notice, and I can make a sidebyside comparison there hehe. But I am still curious about measured black level tho. It looked a bit darkgrey, the 59" d550.

oh now I checked it out blwn. :-) Just havent figured out if the d550 can have same low mll as the d7 and d8s just by "hacking" it.
post #767 of 1918
I originally had a pn51d490 but decided to go full HD with this d550. Followed the instructions to hack it to the higher d7000 series and love the picture quality. I am by no means a true videophile like some of you are but it looks great to me. I don't notice any brightness pops and the black level is just fine for me.

Alas, it's going back for a replacement though. The buzzing it's giving off is incredibly irritating. The d490 I had you can hear it only if the sound was off and you were about a foot away from the tv. This one I can hear above the normal tv volume at 8 feet away. Fingers crossed for a perfect model.

Based on your sig you should pass on the D550. Black levels aren't fantastic and my only real complaint (brightness / black level pops is a minor issue) - but I paid a small sum for this tv, nothing close to a D7000 - 50% or less so not complaining. All I can tell you is during the day with curtains partially drawn I have the cell light to '11' and at night to '8' with movie mode on and all settings to default. Plenty of contrast and lovely, natural colour saturation. I'm always self-calibrating my screen visually, trying to ensure it's as close to looking like I was there personally. More cell light or brightness and you'd spoil the picture, inflating it artificially. The D8000 review on CNET states the blacks are 'inky' with the D7000 possibly the same but I'm not able to comment. I wish that was the case with the D550 but as I've said, you cannot compare the two. If you have the bucks, blow it on a high-end unit. All comes down to financial means and priorities

Other thing is the processing of judder is somewhat poor on the D4/5 series'. I'm sure the higher-end units will be better on that front. I owned 2 x LED's - Sony and Samsung C6500 and they were certainly superior too. But at this price point all imperfections are acceptable.

No, this is not right. If you are hearing it AT ALL when viewing your TV there is a fault. The only way I can hear the tiniest of a buzz is if I place my head right up against the back of the unit. Yours sounds like a completely different situation and must be returned. Shame on Samsung for not testing these units better - bullsh*t as to what the customer must go through to arrange a replacement. Better luck on the next!

I play a lot of video games and watch TV of course, do the brightness pops occur during those?

In my experience, Dynamic Contrast to 'low' doesn't fix a thing. Nada. I do *not* notice the pops in game play (ps3) so it certainly seems to occur on playback of digital files such as xvid/divx/x264/h264 etc and possibly tv too (but can't vouch for this). No issues with blu-ray. So it's there but really isn't a big deal - I got used to it. For the price and decent picture (and all the crap you can get from other tv's incl LED) I submit to the imperfection
post #771 of 1918
thanks andrew. Well I can live with 0.007 fL or something. Its in my nature to try to see if theres a way to make cheap things act like more expensive by tweaking. i.e d550->d8000. But I guess that's not the case when it comes to mll this time. :-) Ah.. back to square one. Maybe that ps58c6500 isnt so shabby after all. (cheaper than d550 and possibly a bit better blacks. ) :-)

edit: comment about blacks: every little helps! black is black, and grey is what's between white and black. :-) My opinion. And I will not comment it further , I am here to look for a tv-set that might suit ME.
post #772 of 1918
here is what another member posted about the sets and models and i agree 100%..........

I SINCERELY query this. I reckon black levels on the higher-end units will be far superior. And judder where the D550 really suffers (even poorer than LED's I've owned). But not much else to add here. And I'm going off-topic



far superior!! lol.

we are talking so little amounts my friend. i mean points of percentages.. lol.. i would say they are far superior than a 10 year old plasma.

but not far superior in this gen.

i mean.. you can notice the difference between a kuro and panny and a sammy no doubt.

but side by side..

black levels funny. i watch my tv.. not the black levels or the judder or the line bleeding or the phosphor trails.

i don't turn it to a blank input and watch the image retention.

i don't turn down the volume and listen to the buzzing.



enjoi the set if you have one.

if you don't.. then find something else to enjoi

black levels are not much different from the models.. but if you read the rest of my post.. you would see the part i wrote about black levels. i don't talk about black levels.. because i think they are a joke.. they freak people out.. they always want meter readings and OMG it's 0135 mll ..

ZOMG.. i am not buying this set!!! cuz last years model was 0127.. lol

When it comes to PQ and CMS and Color Accuracy. this set is freaking great!.. they even are saying this on reviews..

I know the 3d is great. i know the PQ is Great!





i notice no judder.

i am not a picky person. within reason. if there is a big yellow line running down the display i will return it.

if there are 30 dead pixels.. that i can see when my nose is pressed up on the display.. lol i won't return it.. because there is no way you an see them unless you are trying to see them..

i think folks that look for problems find them.

the only difference between the higher end panels is the Real black filter (AR FILTER).

they have the same engine/processor.

the same CMS system as well.

that's why samsung is king this time around.. because they pretty much included everything in the lower end models.

black levels are funny though.

really you can't tell the difference unless you have them side by side.. and like D-Nice said mostly placebo.

yes the smaller panels have less black level.. but we are talking sooo little it's not even funny.. when you are dealing with 00 points of percentages.. lol.
post #773 of 1918
on another note... i went to Fred Meyer awhile back and they had a pn51D550 and a 51D7000 beside each other.. so the wife and i stood there and watched both for awhile, they both had the same show on.. we both hated the look of the antireflective coating on the screen of the 7000.. the grass in the yard on the 7000 looked like a cartoon compard to the 550 with out the coating... after standing there watching both sets i am so glad i didn't buy a set with the coating on it.. and i was wanting the D6500.. But for me i am able to control the lighting in my house so the glare was not a big deal.. now don't get me wrong.. the 7000 has alot more then the 550,and the picture would be alot nicer then the 550 if they offered it with out the antireflective coating on it.. to me anyway... but i guess if you just wait awhile the coating will come off..

According to the Samsung technician I talked to (and one of the first pages of the manual to the TV as well if I recall correctly), buzzing that can be heard at low volumes or in quiet passages at medium volume - at normal viewing distances - falls within normal operation and is not an indication of a fault in the TV.

With bright or high contrast images, mine buzzes loud enough to be heard in those conditions (no audible buzzing on dark images, unless I put my ears to the TV), but the technician - and the most convincing reports I found through a lot of Googling - convinced me that there's nothing wrong with my TV.
Since I don't hear the buzzing the vast majority of the time under normal operation (and have additionally gotten so used to it now that I barely notice it even when I have the TV running muted during eg. commercials while I do something else), I've chosen to live with it, but the Samsung technician did say of course that if I felt I couldn't live with it I should contact the store for a replacement.
If I had, I imagine that replacement could then have turned out to have the same, lower or louder buzzing - and potentially any number of other minor flaws these sets suffer from (and which my current one doesn't seem to have any obvious examples of). I decided it wasn't worth the trouble - although obviously anyone who is genuinely dissatisfied with or worried about their TV should of course do something about it.

Hey ppl,

I have had my PS51D550 for about 2 weeks now. Awesome 2d picture but I think I may have a fualty unit because my 3d is messed up.

It happens in 3d games, 3d Blu-ray movies and even on free to air 2d to 3d conversion.

It's quite hard to explain in words but it seems like there is alot of colour banding and bleeding going on. See below pic to see what I am talking about



That was taken on free to air 2d to 3d conversion. It's unwatchable.

Is there some major setting I have missed or do I have dud unit?

Thanks guys,

Fuz.
post #776 of 1918
Ouch, that looks terrible. Definitely nothing at all like when I'm using 2D to 3D conversion on any content - SD or HD - which remains as artifact free and sharp (or not so sharp if it's old 2D content) as viewing it in 2D.
No settings I've found - and I think I've messed around with all of them many times by now - have had any obvious negative effects on that.

I'm learning to live with it...

It bothers me for sure, but there's no guarantee I'll get a replacement that doesn't buzz... and it was a real hassle to get the TV into my basement...

My biggest issue right now is colour "streaking" or "banding" when I'm using my PC on the TV: On the page right where I'm writing this message the black text is causing horizontal bands of darkness (barely noticable but still there nonetheless) across the white and and blue background...

It's quite apparent (to me) when I scroll up and down on Google search results...

From my research it's just another side-effect of plasma technology...

hello im from aguascalientes mexico thank you for all the members of this page... well after 2 years whit my panasonic tc.p50x1 i took some photos to see the mll or the black level of the 2 sets my panasonic was calibrated whit the settings of d-nice and i use the settings for my new PN51D550 of the page of cnet using the settings of the pn59d8000,,,, at first when i buy this samsung i looked both tvs and i apreciate a worst black level on the samsung whit the out of the box setting, well i made some changes on the set and the black levels didnt changed but when i unblock the 10 point calibration and i made the changes on the tv woow the black levels was fairly better...
