3,800-hour test could show OLED burn-in is on the decline — MSI MPG 321URX shows only 'minor' issues after 15 months of worst-case scenario use
But a Pro user might have to replace it after just nine months...

A video chronicling the degradation of an OLED monitor over time has just been published, offering a 15-month update. The Monitors Unboxed update seems to deliver pretty good news, overall. After this quite considerable time of “worst-case scenario” OLED monitor use, key metrics are still acceptable. However, it is estimated that the MSI MPG 321URX under test may need to be replaced for color-sensitive professional usage as early as 9 months later. Also, please bear in mind that this interesting study is based on a single OLED monitor sample, unlike the work of organizations like Rtings.
During Monitors Unboxed testing, the MSI 4K OLED has been subjected to a daily use behavior described as “aggressively burning in.” The channel’s Tim Schiesser hasn’t been purposely causing damage to the display, though. Instead, the idea seems to be to use this OLED with the same amount of care you might with any LCD-technology alternative. It is also used primarily for work, with little to no full-screen media content consumption. Thus, it was probable that static Windows UI elements, and even often-used apps, could cause burn-in on some regions of the display. Indeed, this has happened.
Above, you can see a full rundown of the test conditions. In summary, while Schiesser didn’t try to cause max burn-in damage, and allowed the panel to complete its self-protection and maintenance cycles, he didn’t do anything in Windows to lessen potential burn. Therefore, he used Windows 11 in light mode (as some people prefer), didn’t set up a screensaver (just a 2-hour idle-time screen-off setting), and used apps on the same preferred areas of the screen 95% of the time. This activity takes place “8 hours a day, 7 days a week, 250 hours per month, 3,000 hours a year.”
During the video, you will see some interesting images that chart the extent of the 4K OLED display’s burn-in over 6, 9, 12, and 15 months. There’s little mention of the 3-month milestone, as any ill effects of the ‘aggressive’ use by then were very minor.
Trying to see the burn-in issues escalate over the 15 months isn’t that easy, something which we should be thankful for. Thus, Monitors Unboxed has manipulated or filtered the comparison images to show what is happening slightly below many folks’ perception levels when looking at captured image content in YouTube videos (lossy compression issues).
The major areas viewers should be aware of are the bottom of the screen, where the Windows taskbar remains in typical productivity workflows, and the vertical burn-in artifacts, which are caused by Schiesser’s unwavering app tiling preferences. He explained that much of the time, he will work with a browser on the left of the screen and a word processor to the right.
Color impact
As well as the shading discrepancies you can see in the grayness, Monitors Unboxed also looked at underlying color shifts. It was noted that the green subpixel was worst affected by degradation over the 15 months.

These kinds of color discrepancies and shifts will undoubtedly come to a point where they affect professional work that requires color accuracy and consistency. Schiesser estimates that this particular MSI monitor will hit that point at around 2 to 3 years of age, being run as it is now.
Most people won’t use their OLED monitors in such an ‘extreme’ way, it is admitted. ‘Everyday users’ can probably expect a longer burn-in-free OLED monitor lifespan, and might also shrug off some of the pro-color accuracy concerns later on. Nevertheless, the service life of a good IPS alternative, for example, should still be quite a bit longer. Monitors Unboxed says it will continue to regularly update its MSI 4K OLED testing.

Alvar "Miles" Udell Baby your $1050 monitor (current price at BestBuy) or replace it in 3 years, which amazingly is the warranty period of the monitor.Reply -

Oh, yes they will! This is certainly heavy usage, but not extreme by a long shot! Extreme is when like a business puts a monitor in a kiosk or public area and leaves it on like 12 hours per day, 7 days a week, with the brightness set higher than 200 nits. Or worse: they just leave it on all the time - 168 hours/week!The article said:Most people won’t use their OLED monitors in such an ‘extreme’ way, it is admitted.
About the only thing I'd do differently than what this user did was to set a screen blanker for 20 minutes of inactivity. Maybe 15, but I find any less than that tends to annoy me. And that's why I opted not to buy an OLED, when I replaced my monitor in Dec 2023.
Hopefully, my next monitor will be an OLED, though. I'd also buy an OLED TV, because I simply don't watch enough for burn-in ever to be a major issue on it. -

I had my last monitor for more than 10 years, before it started acting up. If I got anything less than 5 years out of a monitor, I'd consider it a poor product. I put easily more than 60 hours/week on it.Alvar Miles Udell said:Baby your $1050 monitor (current price at BestBuy) or replace it in 3 years, which amazingly is the warranty period of the monitor. -

And that's why you go IPS. My Corsair Xenon in my signature has superb colors and 144hz display and I don't have to baby it.bit_user said:I had my last monitor for more than 10 years, before it started acting up.

Elusive Ruse Just bought an LG C4 42” to replace the aging Samsung 4K LCD, will let you know of my first impressions.Reply -
lmcnabney The taskbar became obvious very quickly. We are also getting to a plateau in monitors. They won't be replaced as quickly because we aren't going much beyond 4K on the desktop. I'm still sour over plasma burn-in and I'm not rich enough to replace monitors after three years of use.Reply -

I had a Panasonic plasma that didn't burn in after 11 years of use. I did have a couple of "image retention" issues, but those went away after I learned to be much more careful about limiting its contrast setting, whenever there would be any sort of fixed graphics on the screen, for an extended period of time, which would significantly contrast with the background.lmcnabney said:I'm still sour over plasma burn-in and I'm not rich enough to replace monitors after three years of use.
It was annoying to have to manage, but I successfully avoided any more image retention, and the original instances did indeed fade completely away (as far as I could see).
