OLED Uniformity and Greyscale Test - Check your TV for Burn In and Banding

This video is a short test to check for OLED burn-in, colour uniformity and banding.

For me the red gave me clear indications of burn in on a LG 65C6 OLED, newer OLED TV's are definitely much better at resisting burn in and I also checked on an LG 55CX OLED and an LG 77C1 OLED which were perfect.

What is burn-in?
Burn-in occurs when I leave static images on my OLED screen for too long. This can permanently damage the pixels, resulting in ghosting or image retention. To prevent burn-in, I should avoid displaying static elements like logos for extended periods and make use of features like pixel shifting or screensavers.

What is banding?
Banding refers to visible lines or bands that appear during color gradients. It happens due to slight manufacturing variations, causing uneven color reproduction. While OLED technology has improved, banding may still be noticeable in some cases, especially in lower-quality panels, but this is very rare in 2023 as OLED is becoming ever more popular.

What is colour uniformity?
Color uniformity is about how consistent the colors appear across the entire screen. OLED panels can have slight variations in color and brightness, leading to certain areas looking different from others. This issue may be more apparent in large areas of solid color or when viewing the screen from different angles.

You can help to prevent burn-in by avoiding static images and using features like pixel refresh and screensavers if using as a monitor.

LG C1 user here. Put nearly 13K hours into this TV and it’s still just as amazing as it was when I first bought it back in November 1st, 2021!
No signs of burn-in nor various uniformity issues whatsoever. Then again, I use it for movies (mostly through 4K Blu-rays and my iTunes/Apple TV movie purchases), sports (mostly soccer, basketball, and F1 racing) and gaming (in my case both the PS5 and Xbox Series X), so a little bit of everything, lol.

For anyone doing this test on their phone : Make sure you’re in a dark room skip to 95% greyscale, set your brightness to about 35% and zoom the video fully out in portrait mode so that your screen is 100% covered. If you’ve had your phone for at least a year, you’ll see burn in. It doesn’t show at 100% brightness at all.

Its all fun and games until everyone arrives at the 95% greyecale

ok if you got a new oled screen and have those vertical lines on greyscale, i advise you to wait couple of months. I was worried whey i bought my expansive monitor because the lines ware really noticibe but after 3 months and a couple pixel cleaning cycles it went away compleatly.
Give it time and take care.

Don't watch this video if you are blissfully happy with your TV....

2 years of phone oled and still not a single sign of burn in, but to be fair i using it on all form of media and not using it in full blast brightness

[martinchuter]

What are the white square blocks across the very top of the screen above 80% grey???

So my iPhone 12 mini’s burns after 3 years are visbily in the greyscale over 90% and of course it is the battery, WiFi and others in the areas beside the notch and the white bar at the bottom of the screen 😂 . That is actually a massive step up from back in the day where my s7 samsung had visible burn in during normal use a year in.

LG C2 here, used for gaming, movies and TV shows. Had the TV over a year and so far so good. (No Burn in detected) My old LG OLED had some gnarly burn in but that was an early gen TV so it was gonna happen. (it still gets used as a TV where the burn in is less noticeable)

I’ve not got an OLED tv, but just ran this test full screen on my iPhone 15 Plus in a dark room and it’s flawless, even on the 95% slide. I guess it’s more of an issue for larger panels though.

[ChrisDavis]

I’m scared to run this on my new oled because if it’s janky I’m never going to forget it

[cruisertechgt]

iPad Pro M4 with Tandem OLED checks good. No Vertical Banding or uniformity issues.

[AIRDRAC]

Sony Xperia 1 iii (3.5 years old) - I have a large blob of brighter light, with a ring around it that is darker than the rest, visible from 60% greyscale and onwards. Other than that, no visible burn-in.

[N-e.o]

I returned my newly bought TV based on this video, screen uniformity was bad and some banding... Just received my replacement but I'm too scared to run it again .. what should I do? It seems the replacement is better at first glance but still too scared man

[leerobinson]

Whats with the 4 shapes at the top of the screen above 80% there like squares made of 4 blocks, 2 black and 2 grey, are they part of the video they dont show up on other greyscale videos

You're doing a fantastic job! I need some advice: I have a SafePal wallet with USDT, and I have the seed phrase. (air carpet target dish off jeans toilet sweet piano spoil fruit essay). What's the best way to send them to Binance?

My button navigation bar got a slight retention, thanks god I found this out early and switched to gesture navigation.

There's noticeable burnin of some windows taskbar icons and groups of dead pixels on my LG C9. I never used it past 60 brightness since I usually watch in a dark environment. Also, it's strictly used as a display for a htpc so the taskbar is rarely visible (switching movies, downloading, copying or deleting stuff etc.). It's only 4 years old. My older LED TV was abused for 10 years and I only upgraded because I wanted better picture quality, otherwise looked brand new. Quite disappointing big reviewers love to advertise burnin is not really an issue we should worry about it when it clearly is.

Also trying on me Xiaomi 11 lite, using since 2021 and cleaned, no burn in until now

[scottsacala]

Can anyone clarify if each slide is absolute flat in color? Or due to YouTube compression, there are certain inconsistencies in some of them? I see some at 95% on my OLED tv, but am not sure if that’s burn-in or YouTube compressing the video.

I can’t really test it on my phone because there’s already burn-in on there, lol.
