Burn-in, it's the final frontier for OLED technology. Fix that, and we can all ditch our LCD panels, right? Well, , we're tantalisingly close to that outcome, but not quite there.
Roughly, that's about eight [[link]] hours a day on the Windows desktop with worst case scenario settings including Windows Light mode, not auto-hiding the task bar and so on. In fact, Monitors Unboxed also only allowed the MSI MPG 321URX's pixel cleaning and compensation cycles to run every eight hours instead of the recommended every four.
All told, Monitor Unbox estimates something in the region of 2,700 to 3,000 hours racked up. The result? A very slight line down the middle of the display that's a consequence of routinely running two main application windows side-by-side, plus a touch of burn in where the taskbar resides.
It's really important to note that both of these "burn-in" remnants are just barely visible and even then only on certain shades of grey background. Monitors Unboxed says that the burned in areas are entirely invisible most of the time and barely a distraction when they are.
Still, there is some burn-in, it's not absolutely zero. Interestingly, Monitors Unboxed has found that the progression hasn't been entirely linear. At nine months the burn-in seemed to have regressed a little compared with six months. At one year, it's back to roughly where it was at six months. That probably reflects the impact of the compensation cycles.
Monitors Unboxed says that its usage has been particularly heavy and suboptimal for an OLED and that it equates to at least 18 months and more likely two years of normal "mixed" use of desktop work and gaming for most people. That means after two years, most users should expect to see very little burn in.
One other detail that's worth noting is that Monitors Unboxed has been running the MSI MPG 321URX at 200 nits. The panel can be set to up to 250 nits, and the brighter you run a monitor, the worse the burn-in would normally be.
My experience with the MSI MPG 321URX would certainly see me maxing the SDR brightness out to 250 nits, day to day. Even at that setting, it's only just bright enough for my preferences. Then again, I use dark mode for just about everything as a matter of course, so maybe that would make taskbar burn-in a non-issue.
Overall, it's hard to know exactly what to conclude from this test. On the one hand, the results are probably better than you might fear from this worst-case scenario. On the other, the fact that the panel showed any signs of burn-in at all remains a worry.
How you use an LCD monitor, in comparison, just isn't something you need to think about. Meanwhile, as Monitors Unboxed says, if you're spending $1,000 on a monitor, you should reasonably be able to expect it to last for about five years without major issues. And [[link]] on the basis of this test, it's still not totally clear that would be the case.
: Pixel-perfect panels for your PC.
: Screaming quick.
: When only high-res will do.
: Big-screen 4K gaming.
Monitors Unboxed plans to keep going. So, if they clock up another year, that'll be around four years worth [[link]] of up time for a "normal" PC enthusiast and pretty close to an idea of how things look after really long term use.
What's more, Samsung, which makes the QD-OLED panel in question, and is claimed to be yet more robust.
My sense is that the 3rd Gen QD-OLED panel used in the MSI MPG 321URX is already fairly resistant to burn-in. So, if Samsung really has made further progress with the latest panel tech announced in January, then burn-in should really have been relegated to a non-issue.
All the signs look good, but that will, of course, need to be proven in the field. The reality is it will take time. That new panel tech is only just now being put into displays, so that final reassurance is still a few years away. Watch this space.
