If I watch lower res content such as satellite programming (720p), it does become visible at times over certain colors, such as light backgrounds and skin tones.

Honestly, if I were not so picky I'd probably never notice it but since I know its there I cant even watch TV w/ out looking for it. I don't think my wife has noticed it yet and I don't want to mention it to her because then she'll be plagued by it like I am. I'm considering calling LG but wanted to get your opinions. Is it worth the risk of getting another one thats possibly worse? Or is it even worth the opportunity cost all together?
I'm probably going to spend a little more time with the break-in DVD and also watch some more blurays to see if it really annoys me. Bluray and PS3/XBOX 360 gaming is the majority of what I'll be doing and if it doesn't show up on content from those sources I'm probably not going to worry about it.

I've posted a few pics I took of the screens while playing the break-in DVD. I noticed vertical lines on the screen in the pictures...I didn't even notice these when I took the pics! What do you guys think? Should I try for a replacement?

(most of my uniformity issues are in the center of the screen)
My TV looks exactly the same. I showed it to an LG rep and he said he could change the panel but it would probably be the same in the new panel. If I never ran slides or read about the issues on this thread I would have never noticed it. I've decided to live with it and enjoy my tv.

If you read through earlier in the thread, this TV is known for this uniformity issue. If you feel it is too much you would probably need to consider a different brand/model.

Good luck!

Even if I could right now, I'd still be worried about giving up a screen that's working pretty good now for another one with image quality problems like my last pk540.

In one hand, I'd rather have a smaller screen with better picture quality or no problems than a larger screen with problems. Funny though that my last plasma was 42" and at first the 50" almost seemed too big and took a bit to get used to and when I see a 42" now they look sooo tiny, heh. "I used to watch movies on a 42" !?" I can just imagine how immersive the 60" would be. Another caveat I'd worried about is image distortion/noise sticking out more with a bigger screen - it surely does going from a 42 to a 50". I REALLY hate film grain!

I still haven't decided 50" or 60".
My worry about 60" screen is the picture quality as I watch a lot of dvd's, and my viewing distance is between 6 and 8 feet (9 feet max)... isn't that too risky for seeing picture defaults?

I've seen both in a store yesterday. On the 60" it was a dvd playing... and the picture quality wasn't good at my viewing distance (7 feet). At 10-11 feet it was ok.

Gosh it's so hard to make a choice I won't regret! Sometimes I think: "let's go for the 60", even if it's the double price of 50".

Anybody has watch a dvd on a 60" set at a viewing distance of 8 feet???

I went from a 43 to 60. You WILL regret not getting the 60 in about a week and then tell yourself over and over again how it's not that big a deal......knowing the whole time you should have got the 60 to begin with. Get the 60.

I sit anywhere from 7 to 14 depending on what I'm watching.

Thank You for your advice.

I get your point but the problem is that my maximum viewing distance is 10 feet.
I'm sure it will be great for Blu Rays, but I'm afraid to see too many artifacts when watching dvd's and TNT SD...

If I save money and get a 50", I might sit at 5 feet to enjoy my Blu Rays, and sit back at 8" for DVD's???

It's a tricky choice: save money and get the 50", or invest in a 60" risking bad picture quality because of short viewing distance?

HEEEEEELP!

.. another consideration: some movies, specifically the Iron Man (Blu-ray) recently viewed, was filmed in different aspect ratio than standard, therefore a 'notible' portion of the screen (top & bottom) was black. That cuts into total available viewing 'pleasibility'.

You can also try the following JPEG file on your screen to see u got any line bleeds like below...

Line bleed...

I just downloaded your test file and tried it on my LG 60PK550 and I do not see the dark shadows your image shows on each line of text (line bleed).
I see only slight shadows at the top and bottom edges of each line of text, and they are so faint that if I was not looking for them I don't think I would have noticed.

Does yours look worse in the picture than in reality?

Please help me! Will 60" be too big? (for picture defaults)

Is a 50" at 6-7 feet the best solution?

Thanks!

I have the LG 50PK550 and I sit roughly 6-9 feet away, depends on video game, normal TV viewing, or Blu-Rays. Previously I was using a 24" monitor for everything (had moved and gave away my 36" Sony CRT, just too damn heavy to move again...lol), so for me it was a huge difference. I did get used to it, but I still feel it's perfect for my viewing distance. If you are going to sit further away more often, or with other people, then I would go for the 60".

Actually I sit at the same distances as yours (even a bit closer)...

I sit at a distance of about 8 feet. No regrets. Although i have the green pixels, but you can only see them when you are close to the tv, which you should not be anyways. Besides, you will probably get blu ray soon right? Once you do, you will not want to watch DVDs anymore so the distance will not even be an issue. I have the 60pk540. Get the biggest one possible. you might regret not doing it later.

I recently reset my ps3 to defaults. I was watching a netflix hd film and the green dithering was horrible. I was really nervous. All the blacks were gritty. I checked my display settings and it had the output limited. I enabled the settings specific for hdmi (full range, etc). Started the movie again and the grain was gone.

ok, how do I do this or where do I go? It would be awesome if I could get rid of that green grain. I really love this tv but deep down that really bugs the heck out of me. thanks.

Thought I'd post a comment on how I fixed my buzzing 60pk550...

When I first got my tv it was as quiet as a mouse and then about two weeks in it started making a loud buzzing noise.

Here's what I did to fix it... On the back panel I located the exact spot where the buzzing was coming from, found the screw closest to it and cracked that sucker loose about a quarter turn or so and *BAM* no more buzzing.

Other's may need to loosen more than one screw, but the point is if your tv's buzzing then fix it.

I was very close to exchanging this tv and I'm glad i didn't, this one has a perfect screen no line bleed, dead/stuck pixels ect.

Hope this helps out some of my fellow pk550 users.

Enjoy!!!

On the PS3 you go over to setting and then down to output settings. You'll find it in there as well as the super white option

Yep, I forgot to clarify that the setting is on the ps3. I really hope this helps a bunch of you out. The difference was very drastic with the setting on vs off.

Granted you still have the dithering, but it's not noticeable with the proper settings.

Update: The repairman came & is now gone. The TV is still in the same condition. The issue may be the panel, but they are on national back order with no ETA. He's coming back next week with the only other part that hasn't been replaced other than the panel. If it still malfunctions, what then? That would be visit number 7 in a 7 month period. What if they intend to not make any more panels?

Also of note, Super White doesn't affect RGB since it is used on the PS3 only for Y Pb/Cb Pr/Cr signal types.

So which provides a more accurate calibration, RGBFull with High Black Level or RGBLimited with Low Black Level? I have a few other sources I'm using RGB with and set it per input as needed, but I don't know if it's affecting the numbers you posted.

LOL...This actually happened to me. I have roughly 400 DVDs (Had over 600, but when I split with my GF, we divided up the movies). Anywhoo, after getting this set, I bought a PS3 to watch Blu-rays, and I haven't wanted to go back to them since. I have around 25 BDs now and growing.

My set is still not pro-calibrated, and I'm still hoping to pick up colorimeter sometime this spring, so I've been tweeking how it looks using Spears & Munsil BD and how various games/movies look. Below is how I have mine set up right now for the PS3 for gaming, it may not work for yours, but it looks excellent on mine.

Mode: Game

Contrast: 80
Brightness: 24
Sharpness: 36
Color: 42
Tint: R12
Color Temp: 0

Advanced Settings:

Dynamic Contrast: Off
Dynamic Color: Off
Noise Reduction: Off
Gamma: Medium
Black Level: High
Color Gamma: Wide
Edge Enhancement: Off

On PS3:

1080/24p
CLR Space: Y Pb/Cb Pr/Cr
Super White: On

If you change Color Gamma to Standard, then increase Color to 48, everything else is the same.

That's strange, The RGB output should always be set to limited for movies. Only computers and games should use the full range. Sounds like you have a calibration issue if you are seeing full look better.

I use RGB Limited with Black Level set to Low except for the rare occasion when a PS3 game looks washed out and can't be corrected with the in-game gamma/brightness setting.

I didn't realize that. I'll trying changing the black between high and low (based on some recent posts). Maybe that will help. I need to read up on this some more...

I noticed that my 60PK550 black level (MLL) increases by 50% when watching a 1080p24 input compared to a 1080p60 input.

Picked up a 60PK250 at Costco yesterday, let the set acclimatize overnight and fired it up this morning. All I can say is WOW, great set for what I paid.

I have used Brad's settings for 32 and 40 and have watched some HD Net and Saving Private Ryan with fantastic results. Thanks soooo much for sharing those settings.

I am running the break-in slides on the VIVID setting, is that OK? I noticed the only major difference between the suggested settings and VIVID is the colour setting.

Also - based on the 32 and 40 settings posted in this thread, what should I have the ENERGY SAVING setting at?

I haven't see any IR on my set so far or any debris behind the screen. Screen uniformity is good too. Also, not stuck pixels or anything of the sort that I have noticed.

This is a really good-looking set, especially at this price point.

I am running the BIS with my PS3 as this unit doesn't have the USB port.

Thanks.

Edit - I do see line bleed - someone was sitting in front of some blinds on HD net and the lines of the blinds kind of carried across the face. Hoping this dissipates as I get more break-in time. Also, the screen is VERY reflective. Mine's in a basement, so not a big deal for me, but if in a bright room with light behind the seating area/in front of the screen, it would be distracting. One other thing - I don't notice any hum at all from my set.

The only useful setting for Energy Saving is Off. Anything else dims the panel too much.

Does yours look worse in the picture than in reality?

I also used the slide to check for line bleed. Before I thought that I had none. I do have the defect though. It does not look as bad as the posted example. It is not visible on the text lines at all. I only see it on the solid horizontal lines that box in the text. I have not yet seen the effect when watching any kind of video content. I am not happy that it is there, but it does not reduce my enjoyment of the display under "normal" circumstances.
