Image retention is a thing and it happens in as little as a few minutes of a static image - but you'll never notice it and it's nothing to worry about.
If you play a game for a few hours which has a completely static UI, and then throw up a white screen you can see that the TV slightly
dimmed down that section of the TV to prevent further retention. If you throw up a solid dark gray image, you can usually barely make out the UI right after a gaming session. Dark gray is the only color that will show it. This goes away simply by turning the TV off then back on, or doing something else for a minute or so. I have never noticed in real content, I only noticed it when I was new to OLED and being careful by throwing up slides to check for burn-in all the time.
My friend who has the much older Samsung OLED (RGB OLED way more prone to burn-in), got his task bar burned in pretty bad after he left his computer on few a couple days with no screen saver enabled. It was very noticeable in real content. He hid his taskbar for a few weeks, and now even on solid images it's completely gone.
I'm a firm believer that permanent burn-in is near impossible on these. Even if you let it get out of hand by keeping a computer on for a few days, with no moving images, my guess is that running the TV with a moving image for the same amount of time would clear it all up. The TV also offers a feature that will shut the TV down for one hour, and do a thorough cleaning of the panel. I've never had to do it, because every time you turn the TV off normally it does a shorter version of it.
With that said, I would still recommend running a screensaver just because they are so expensive.
Thanks for sharing.
I guess that from what you said newer models from 2016 and future ones will be good enough for general usage based on what you said about them having solved the blue problem and the several mechanisms to clean the panel of image retentions, but the professional photo editing example I gave can still present a problematic scenario where precision is paramount and in contrast to the image retention that happens when displaying static images for a few minutes.
Say, you're editing part of an image on the right and then go to the left and can't really rely on what you're seeing and the outcome of your editing because there will be an image retention overlay of how the image was previously, skewing the feedback that the monitor is giving you of what you just changed / wanted to change on the image. It could be tricky to work with such a monitor. With a conventional monitor image quality isn't as good and the backlight may not be the most uniform ever, but you're working with a more steady set of conditions over a normal workflow period.
Could that be the reason for them to not produce a desktop version? Or is the OLED spacing a problem for long term reliability? Demand would always be low, but I'm sure that if the panel delivered there wouldn't be a lack of professionals wanting and being able to afford one.Edited by tpi2007 - 1/11/17 at 10:22am
