One of the biggest concerns people have about buying an OLED display is screen burn-in. It's the one issue that still hangs over this otherwise incredible panel technology, and manufacturers know it. That's why most OLED monitors and TVs these days include built-in features to help mitigate screen burn-in and image retention. However, those features aren't always as reliable as manufacturers make them seem. They sound great in theory, but once you've used a few OLEDs, you start noticing their flaws.
From my experience owning OLED monitors like the AW3423DW and AW2725DF, and even the LG CX OLED TV, panel care features like Pixel Refresh, Auto Brightness Limiter, and logo dimming only go so far. They might reduce short-term image retention, but they can't prevent long-term pixel wear. If anything, some of these features are aggressive enough to affect my viewing experience. That's why I've stopped relying on them entirely and started paying more attention to how I actually use my displays instead.
Pixel shifting isn't magic
The screen may move a little, but the risk remains the same
Pixel shifting is one of those OLED protection features that sounds great on paper, but makes little to no difference in real-world use. Most OLED monitors, including my AW3423DW and AW2725DF, have it enabled by default to prevent static UI elements like desktop icons and in-game HUDs from sitting in one spot for too long. The idea is to move the entire image by a few pixels every few minutes so the same areas of the panel don't age faster than others.
Unfortunately, the movement is so small that it barely spreads out the pixel wear. Yes, you'll see that your screen has shifted a bit if you look at the edges, but that doesn't change the fact that most static elements generally stay in roughly the same area. For instance, your taskbar might move a few pixels, but it's still lighting up the same group of subpixels for hours on end. And over time, these areas will inevitably age faster than the rest of the screen. I find it better to set Windows to automatically hide the taskbar since it helps way more than pixel shifting alone.
Pixel Refresh doesn't prevent burn-in
It can help with mild image retention, but it doesn't reverse long-term wear
If you've ever used an OLED monitor, you've probably seen the Pixel Refresh feature kick in automatically when you turn the display off or leave it idle for long enough. On some monitors, like my AW3423DW, you'll get a pop-up to run this feature after four hours of cumulative use. It feels reassuring at first because it seems like the panel is actively taking care of itself, but it isn't really as impressive as it sounds. All it does is rebalance voltage across the panel to clean up minor uniformity issues.
In my experience, Pixel Refresh comes in handy for clearing faint ghosting or image retention after several hours of work, where the same browser windows stay open in the same spots. However, if a part of the panel has already started wearing unevenly because the same static elements have been on-screen for months, no refresh cycle will reverse it. Even the longer, manual panel refresh cycles don't improve overall uniformity all that much. So, don't treat it as a fix to restore the brightness of pixels that have already aged.
ABL kicks in when you least want it
Auto Brightness Limiter dims the whole screen even when nothing is at risk
Auto Brightness Limiter (ABL) is one of those things you simply have to deal with while using an OLED display. It lowers the overall brightness whenever a large portion of the screen becomes too bright, and it does this without considering whether the content is actually putting the panel at risk. For instance, when you're watching a movie or playing a game in HDR, screen burn-in is the last thing you need to worry about since there aren't many static elements in a moving scene. Yet, ABL will still dim the entire image when the scene gets too bright.
What makes ABL even more frustrating is how unpredictable it can be. Sometimes the dimming kicks in instantly, and other times it takes a few seconds before you notice the image losing its brightness. Some monitors also tend to be aggressive with the ABL, lowering brightness when you open a bright browser tab or drag a large white window across the screen. If anything, it's more noticeable than the protection it's supposed to provide. Sure, it keeps the panel within safe power limits, but that typically comes at the cost of my HDR experience.
Manual care trumps built-in "protections"
If there's one thing I've learned from using multiple OLED monitors every day for the past three years, it's that no amount of built-in protection and panel care features can replace simple, consistent habits. I'm not saying features like Pixel Refresh and Pixel Shift don't help, but you'll be better off treating them as tools to mitigate short-term image retention rather than your first line of defense against long-term screen burn-in. By simply being a little more careful with how you use the display, you can prevent most of the problems these features try to fix. Keeping static elements off the screen as much as you can by using a black background, hiding the taskbar, and making sure bright windows don't stay in the same spot for too long can make a meaningful difference in the long run.
