Grayscale color temperature will drift to lower values and image will become more yellow as blue output will decrease over panel life. Samsung has larger blue sub-pixels and likely some software algorithms to compensate.

All TVs drift somewhat over time so I would not be too concerned if it requires some minor re-calibration occasionally. Many of us are interested in exactly how OLED fares in the long run.

From what I remember in the reviews, the Samsung ABL is much less aggressive (or oppressive ) than LG's so you might be able to use larger window patterns as long as they don't stay on the screen for too long.

How is the uniformity on the Samsung OLED?

Thanks, Wizziwig. I'll report any color drift on the OLED. Thank you for that information.


I'll try the larger window patterns this week. I was worried initially with burn-in and got used to using the smaller window. Also, now that I'm more familiar with the calibration software, the larger windows won't be a problem.

JWhip reported vertical color shift back in post 99. From where I have the set and my sitting position, however, the screen appears one solid tone from end to end.

Bad news guys, I seem to have permanent burn-in. I use this for a computer monitor. My start menu seems to be burned into the screen. My cell light is 3/20. I have computer screensaver set to 1 minute. I was doing research on the new LG OLED for a few hours so my screensaver didnt kick on. This is the first time I've ever noticed any type of IR or burn-in.

I noticed it while watching family guy. It has gone away on backlight 3, but if i put it to 0 backlight and have all white screen its still there.

What's the best way to try to remove the burn-in? What cell light level do I use and what's the best video/program for removal on OLED? I just purchased LG's new OLED (55EC9300) but with this burn in I'm tempted to cancel that order

If it's actual burn-in, it won't go away. If it's IR, regular, varied content might make it disappear over time.

Thought the Samsung was perhaps more robust vs that... Did u use its scrolling bar? think it has one inbuild?

How much time? Minutes, hours, days, weeks?

Did you have the pixel shift feature on?

Yes. Every feature to prevent burn-in including that was enabled. I was not expecting to have burn in at all with cell light set to 3.

Least I can't see it when I do change cell light to 3, only on 0/1/2.

EDIT: Never mind, apparently I didn't
Pres2play's Avatar Pres2play 04:31 PM 08-14-2014
So you can't see the burn in with the cell light at 3 or higher?

Nobody has reported burn-in on an LG OLED, that being said an OLED for a computer monitor is not wise.

Consider yourself lucky, then. I wouldn't put up a static image on my years-old plasma, much less this OLED. Really, you can ruin the screen in less time if you were so inclined.

A full length movie will have a static image for just as long as I would for my computer use. Letter box burn-in would be worse then my burn in I would think.

Does having a higher cell light make burn-in more likely or does that even matter? I prefer a very low backlight, so I thought that would also help prevent burn-in.

Edit:
Wow I feel like an idiot. Just went into the menu to confirm pixel shift was on and it was OFF. I remember turning it on cause I figured I'd be crazy not to have it on especially for use on a computer. It must be input specific maybe? Either way, this seems like its mostly my fault for not having that enabled. I did notice it only allows for up to 4 pixels. Since my start menu is more like 20? pixels would that even help in that situation?

I wouldn't put letter bar in the same catagory as a static image
Sorry to hear about your situation, hopefully it's just ir
Pres2play's Avatar Pres2play 07:25 PM 08-14-2014
First, I want to apologize to you, Rogershomework. That "consider yourself lucky" remark didn't come out right. All I meant is, it's good you can still enjoy the set if you raise the cell light above 3. I haven't viewed anything at that low a setting. I use a setting of 6 and sometimes 9, and keep the contrast at 93. When I get home, I'll reduce the cell to 3 and check the screen. Who knows, maybe I have the same burn in, lol.

Burnin is a scary thing. B4 I returned my 1st gen OLED I thought I saw burnin but it was only visible in the grey scale which on that particular LG was so screwed up I really could not confirm.
Pres2play's Avatar Pres2play 02:05 AM 08-15-2014
Tried all the cell light levels, no burn in noticed.

Not 100% it was burnin but very possible because of neglect. No doubt OLED is like plasma and it is possible. I would never use an OLED or plasma as a computer monitor.

There are good reasons why none of the OLED vendors are yet talking about using OLED's for computer monitors or laptop displays. It will happen eventually but the material lifetimes arent there yet.

To make it the easiest to see, you would want to put the cell light on 0 and have a all gray and/or white screen up.
Pres2play's Avatar Pres2play 10:49 AM 08-15-2014
I checked the cell light levels and ran Grayscale patterns from 10 - 100 and burn is not there. I did notice some very light reddish spots along the left and right of the screen with gray backgrounds. Guess I was wrong about perfect screen uniformity.

OLED is a new technology and we all try and compare is to plasma which it is not. I was seeing some crazy scribble lines at 10ire on my 1sf gen OLED that were not there in content.

I believe OLED has some IR that we do not fully understand and if course the possibility of burn-in. Too bad that we don't have more Samsung OLED sales to better compare with LG in this area.

Didn't Samsung just release a large OLED tablet? Something like 10" or so. I wonder how that will fare with all the static status bars, icons, etc.
Vegas oled's Avatar Vegas oled 11:26 PM 08-15-2014
I finally did see a Samsung OLED today and was able to run my slides on it. perfect uniformity and no pixels out. It did not have the POP of the LG to me but it might of been because it was calibrated properly and the environment was not ideal. Very nice TV, I liked the look better than 1st gen LG but not as much as the second gen LG.

Will you be calibrating your new OLED?

I think the use cases for laptops and tablets are very different. There are very few people who are going to use their tablet for 8 hours a day on a single application (eg excel). It will be possible to get burn-in on the Tab S, but I dont think it will be anywhere near the norm. I would comfortably buy an AMOLED tablet, but wouldnt consider an AMOLED laptop.

FWIW, I feel like anecdotal reports of burn-in on the Galaxy handsets have gone down with each successive generation.

I just might. I do not like the THX settings as they seem too flat. I am guilty of running the LG OLED like a Xmas tree, way to bright.
