Samsung PN**B450 Picture Settings - Page 5

post #121 of 1471
Just a quick question guys. Would it be ok to run the break-in slides in the "dynamic" setting? I noticed alot of the Panny guys break-in their sets in "vivid" so I figured this would be the closest thing on a Sammy to kinda speed up the phosphor aging process. I don't plan to do any normal viewing during the first 100 or so hours, just the slides. Thanks in advance for any input

The only concern I would have is heat, and abnormal stress to the plasma cells. The burn-in images are pretty severe in cases. I wouldn't want to have strong images on my display for hours on end with high voltages(brightness).

Personally, I don't use burn-in images. Full screen content, for similar hours will accomplish the desired break-in.

Sounds good man, thanks for the advice

Just got the 50B450 tonight. Is the screen supposed to have the red touch of color to it too? I Thought that only the frame was supposed to have this. It is only noticeable on black areas when the room is lit.

Not a showstopper, but I find it odd that they would tint the screen like that for no reason.

Also, I must have to let this thing break in a good amount before trying Dan's settings. I used them in a completely black room and the picture was very, VERY foggy, terrible black level (pure grey), and the colors looked VERY washed out. I had my old Pannys on warm and am accustomed to the calibrated "proper" look using D-nice's settings, but this looks terrible. I'm hoping for the break in to change things, but I'm not counting on it.

No the screen is not supposed to have the touch of red to it only the bottom of frame. Sound like you have something wrong with your tv Just by the way you discribe the image sounds like something is very wrong.
post #126 of 1471
Well I have been burning in for about 35 hours with about half of the time at 50% contrast and brightness then bumped both to 70%. I have 100 hours left to go now!

REALLY?! Oh sh*t.

Looks like I'll be taking another trip to sears tomorrow. I'm gonna take a look at the one on display and turn it off to see.

Can anyone else confirm that this TV is NOT supposed to have a reddish screen? I can't imagine how that could get sent out like that. WTF. I'm ordering a Panasonic P50S1 and calling it a day.

Sears better not charge me a restocking fee for this crap.

Ok now how red are we talking about? I just shut mine off and turned on the lights to get it brighter in here and it may have a very tiny redinsh tint hard to say really looks more blackish then anything. I'll check tomorrow in the daytime to see how it looks then. I have the 42 but it shouldn't make a difference. I love my tv I think it has a awesome picture(especially with stereomandans settings). Now as far as samsungs quality control well I cant call that one especially being that mine had a whole palm print on the actual panel Had to have a tech come down and remove the panel to clean it. I have heard people mention how bad there CS is but all I can is goodthings bout that, had pink issue with A450 and they replaced 3 panels then swapped it with this B450 no hassles at all. If you can post a picture I can tell you if mine looks like yours or not but either way after work tomorrow I check it out for you

We're talking red like a dark metallic red christmas ornament. I've got a few pics on my cell phone but that's it ATM. Digital cam is lent out currently. But the red tint is IMMEDIATELY noticeable and obvious. The second we took the TV out of the box, it was the first thing we noticed. I tried peeling off what I thought was a red film over the screen only to find out that it was the screen itself.

It is noticeable on any dark/black areas of the screen when the set is on, giving it a chocolate raspberry flavored appearance.
post #130 of 1471
The anti reflective coating has a purplish/red hue to it. I only notice it when the TV is off, which doesn't bother me. If it is a deal killer for you, then there is nothing you can do because the coating is always going to be there.

I'm surprised that my settings would look so off on your display. Are you evaluating it in a very bright room? That will make these sets look washed out. What is your video source for evaluation? A brightness settings of 52 should not look grey at all. If you have a source that is passing blacker than black and whiter than white content to the TV, then you will need ot reduce your brightness, and increase the contrast from my settings.

Here's a shot of my screen:



I was in a totally dark room with an HTPC connected with RGB color space being used via HDMI.
post #132 of 1471
Help please. My friend just bought the PN50B450. He loves the picture but he watches a lot of foreign films and old films that are 4:3 aspect ratio. The bars on the side of the image are white instead of black. Is there a setting in the menu that he can change to make the white bars black?
post #133 of 1471
Mikeinnj where my tv is I dont have any sun reflecting of it but looking at it in the daytime I dont not see anything like I see on your picture. Now mine is only a 42" so the 50's may have more tinting but mine doesnt look like yours, sorry.
Dice9 your friend can change the side bars to a dark grey but that is it, no black, I believe they do it to keep from getting burn in while watching the 4:3 content.
post #134 of 1471
Dark grey would be fine but the white is distracting. Can you tell me where to go in the menu to change it to dark grey?
post #135 of 1471
He can also stretch it out sideways (full mode), or use one of the zoom modes to get rid of the bars altogether. That's what I'd do.

Dan
post #136 of 1471
He does not like the stretch mode or zoom (nor do I). Is there no way to make the white bars dark grey?

This is an excerpt taken from the user's manual. Hope it helps

Side Gray: When you watch TV with the screen ratio of 4:3, the screen is prevented from any damage by adjusting the white balance on both extreme left and right sides. To prevent the screen burn from happening, select Dark or Light.
Dark: When you set the screen ratio to 4:3, it darkens the left and right sides.
Light: When you set the screen ratio to 4:3, it brightens the left and right sides.

That pic you posted is what the filter looks like on the cheaper entry-level Samsungs. My A450 from last year has a similar purplish coating to the screen. I nicknamed my TV 'Jimi' because of the "purple haze".

Just out of curiousity, what is the manufacture date on your B450? I did see a B450 at Sears that had a really purplish looking AR filter, and then I went across the street to another store that had a B450, and it looked blacker, and didn't seem as purplish. Anyway they looked different to my eyes.

Perhaps on the very early B450's (the first of the '09 models to be released I might add), they were still using the same filter left over from the A450's, but then they switched over on some of the later production runs. I wouldn't rule this out, since I have noticed some other peculiarities on some of the sets I have seen at Sears, with the picture controls on the front of the TV in different places on the same model. I think I saw one A450 at Sears that had the picture controls down on the bottom right (horizontally), whereas on my A450 the controls are arrayed vertical on the right hand side of the bezel.

I wouldn't put it past Samsung to use some leftovers glass/coatings from the A models on their early run of B450s.

So all those who have a very noticable purplish tint to theirs, tell us what month it was manufactured.
post #139 of 1471
Sorry, I can no longer tell when my Samsung was manufactured. I just got done returning it to Sears. No restocking fee though, which was nice considering the display model also had the red tint to it.

Time to order up the G10.
post #140 of 1471
mines april 2009 and it looks more like that dark type also mine the 42"
post #141 of 1471
never mind figured it out
post #142 of 1471
Regarding the AR coating, I was looking at mine and saw that at certain viewing angles you see the purple/red tint more. At some angles, it looks black, and some you see it. This is all with the TV off though. I don't notice it whith normal viewing, but if there was a large enough black portion in the picture, I might if I'm at the right viewing angle to see it.

Mine was built March 09, and at some angles it might look close to mikeinnj's picture.

It's a non issue to me.

You returned your set based on that? It's perfectly normal for Samsungs, it's their coating. It doesn't affect viewing in the slightest, and is only viewable when the screen is off.

Are you going to return your G10 right away if you notice a greenish push to the colors?

I have the B650, same screen, absolutely no problems with screen quality.

I have the B650, same screen, absolutely no problems with screen quality.

I view from several angles in the room depending on where I am sitting, at various lighting levels from very bright to pitch black depending on the time of day. From my bed or the desk, purple tint could be seen on any dark/black areas during the daytime or if I had my lights on at night.

Before this, I had a Panny 42PZ700U that I absolutely LOVED, but just wanted a 50". If it was a 50", I would have never gotten rid of it. After that I got the Panny P50X1, LOVED the color, black levels, but was close enough at my main viewing spot (About 6 feet) to notice the faint diagonal lines on bright areas. The same lines that C-net mentioned in the review that I read after noticing the lines myself. I use an HTPC and could see the lines a lot on any still album arts/photos in media center. I then took a chance with the Samsung plasma.

The colors were great, black levels were pretty good (not quite as deep as the X1, but I was willing to take it as a trade off to diagonal lines), and I would have kept it if not for the purple screen. I was trying to decide whether to return it or not, then came across the Panny 50G10 for $1250 free shipping, no tax and with a free-after-rebate bluray player, which I will be reselling for $200 to a friend. So I paid $962 for the Sammy after tax and got all of it back after refund. The Panny will be $1050 said and done. That for me was a no brainer. Less than $100 more for some of the deepest black levels available, accurate color out of the box with THX modes, Viera cast FWIW, no purple screen, no diagonal lines, and 1080p FWIW with HTPC.

I'm not going to be against Samsung or anything. They make a great TV and was about to return the B450 to get the B550 if not for the Panasonic deal. The B550 has the grey touch of color, great black levels, but was going to be $200+ more than the G10.

I just can not understand why the need to tint the screen a color. If I was in a dedicated dark viewing room, it would not be an issue, but this is used at a variety of viewpoints at all times day and night. There was just too many times when I would be at just the right angle or lighting condition and see it during credits, black bars, scenes in black space, and even some darker colors in general. Still don't see why the need to tint the screen a color. Does it help improve contrast? Is it purely cosmetic?

As for the green push, Cnet said the same thing about my PZ700U, and seem to say "innaccurate green" on every Panasonic review. Luckily we have D-nice's service menu offsets to counter that. I won't be returning the G10. I never would have gotten rid of the X1 if not for the diagonal lines.

Does anyone know what Samsung's warranty policy is concerning dead pixels, I have one on my 42B450 (I believe it was probably there since the beginning, tho I only noticed it a few weeks ago, I've had it a couple of months now). I only noticed it once I got a Wii which has the white menu and when I was actually up close. It doesn't effect my daily viewing, tho it is annoying to know that I have it there. It is situated almost in the middle of the screen horizontally and about 2 inches from the bottom vertically. Is it worth a warranty call, or do they consider a certain number of dead pixels acceptable?

Welcome jake, from Samsung's support FAQ:
What is your policy on defective pixels?

One or two dead pixels out of the approximately 300,000 to 1.3 million pixels on a typical LCD television is normal. Generally, then, if you have only a few dead pixels, service is not an option.

With that said, what we do about an LCD TV with dead pixels depends on:

The number of dead pixels
The location of the dead pixels
The color of the dead pixels
The size of the LCD TV screen
If you are having a serious problem with dead pixels, gather the information listed above and call Samsung Customer Care at 1-800-Samsung (1-800-726-7864). Have the model number and serial number of your TV on hand when you call.

Also here is an answer given from Samsung to a member disorganizer:
samsung gave me a stuck-pixel answer for my 46":
>2 defective full-pixels
or
>8 dark subpixels
are "needed" for replacement. well at least thats what the support guy on the phone told me.
as far as he told me a permanently lit pixel (in my case a green one) counts as full pixel, whereas a pixel which only shows when one of the subpixel colors are displayed counts as subpixel.
so to count you need to display the main colors and see whether your pixel is always there or not.
in my case its a full pixel because it exists on all colors :-)
post #147 of 1471
Thanks, that seems to pertain to more to LCDs, I did find this regarding plasmas, seems pretty similar.
"Dead Pixel Policy

One or two dead pixels out of the approximately 2 million pixels on this PDP (plasma display panel) is acceptable. Generally, then, if you have only a few dead pixels, service is not an option.

With that said, Samsung does have a Dead Pixel Policy. Receiving warranty service depends on:

* The number of dead pixels
* The location of the dead pixels
* The color of the dead pixels
* The size of the screen.

Please gather the above information and follow the instructions below to contact us."

So I am assuming with 2 or less dead pixels it isn't even worth a call, as anyone had similar issues and tried calling? Also I did hear/read that Samsung had a zero defective pixel policy, but I believe that was more for LCD computer monitors. Also on closer inspection it seems like only one of the sub pixels is dead and not the whole thing (I believe it's the green part, since it the rest of the pixel gives off a purplish color on a white screen and only 1/3 of it looks black) this is probably why it is only really noticeable on a white screen.

Upon finding this site and thread quite by accident, I just had to register and submit my findings. First, since my model is the PN42B430, what I write may or may not even apply to the 450, but assuming it does it may be of interest. Secondly, thank you stereomandan for I have combined your Tint and White Balance settings with the ones I had been using, and most certainly any issue I may have had with flesh tone in particular has diminished.

I have applied your settings verbatim AFTER watching "Defiance" on Blu-Ray (having not found this site at the time) and have been very impressed with the result as I have replayed certain chapters of the film. Unfortunately I rent movies seldom but am looking forward to the experience in the future.

Now for HDTV channel programming I find that I must revert to the settings I had, but implemented your Tint and White Balance findings. Again, it is likely enough that the models are different that I do so. However if the models are in common I would be interested to know what some opinions are of them. Again, this is strictly for watching television. Sorry for babbling on, and thank you!

Is there a way on this Plasma to tell the number of hours watched?
post #150 of 1471
to check panel hours you have to go into the service menu.
