OLEDSnapUsing an OLED monitor with a Mac
By Tyler Pollard · October 2026
An OLED monitor's own burn-in protection helps, but it wasn't designed for a Mac desk layout that stays put all day. Leave it on, then add the macOS settings and habits below. Most of them cost nothing.
I've burned in two OLED monitors with the same Mac layout: a 27-inch Samsung Odyssey OLED G8 in six months, then a 32-inch LG UltraGear OLED in four. Both had pixel shift and pixel refresh on the whole time; the monitors move the whole picture, but my windows never moved.
This guide is for anyone using an OLED monitor with a Mac at a desk, for work as well as play. It's written by the developer of a Mac app for OLED screens, but everything up to the last section is free and built into macOS or the monitor.
Burn-in, also called image retention, happens because each OLED pixel makes its own light and wears a little as it does. A pixel that shows the same bright thing for months wears faster than its neighbors. Eventually that shape can show faintly on top of everything else. Games and video change constantly, so they rarely cause it. A desk setup does: the menu bar, the Dock, and window edges and title bars that sit in the same place all day.
What your monitor already does
Your monitor has its own care features. They're the first layer, so leave them all on. Names differ by brand; look for these in the monitor's on-screen menu, often under a heading like "OLED Care" or "Panel Care".
| Feature | What it does | What to do |
|---|---|---|
| Pixel shift | Moves the whole picture by a pixel or two on a timer. Dell's Alienware panels shift one pixel every 3 minutes. | Leave it on. You won't notice it. |
| Logo or static-area dimming | Finds bright parts that don't change, like a logo, and dims them a little. Samsung calls it Adjust Logo Brightness. | Leave it at the default. |
| Short refresh (Samsung: Screen Optimization) | Evens out pixel wear while the monitor is off. Samsung runs it when you turn the monitor off after 4 or more hours of use. | Turn the monitor off with its power button or let it sleep. Don't cut power at the wall. |
| Long refresh (pixel or panel refresh) | A longer routine the monitor asks for every so often. It can take from several minutes to an hour, and the screen stays dark. | Accept it when asked, and don't unplug the monitor while it runs. |
The one habit that undoes all of this is a power strip or smart plug that cuts the monitor off when you leave. The refresh routines run on standby power after you switch off. Keep the monitor plugged in.
macOS settings that help
The menu bar and the Dock are the most static things on a Mac screen, and macOS can hide both. These take about five minutes, all in System Settings. Paths are for macOS 26 Tahoe.
- Hide the menu bar. Menu Bar ▸ "Automatically hide and show the menu bar" ▸ Always. It slides back when you move the pointer to the top. On macOS 15 and earlier the setting is under Control Center.
- Hide the Dock. Desktop & Dock ▸ turn on "Automatically hide and show the Dock".
- Turn the display off when you're away. Lock Screen ▸ "Turn display off when inactive" ▸ 5 or 10 minutes. On a laptop it's "Turn display off on power adapter when inactive". An OLED pixel that's off doesn't wear, so this beats any screen saver.
- Add a corner to turn it off now. Desktop & Dock ▸ Hot Corners ▸ pick a corner ▸ Put Display to Sleep. Flick the pointer there when you get up.
- Hide desktop icons. Desktop & Dock ▸ Show Items ▸ turn off On Desktop. Icons on the desktop sit in the same spot for months.
- Use Dark appearance. Appearance ▸ Dark. Fewer pixels are lit brightly, so the whole panel wears less.
Habits that help
Wear depends on brightness and time. Lower either one for static content and the risk drops.
- Turn brightness down for desk work. Documents and code don't need HDR peak brightness. Many monitors let you save a lower-brightness picture mode for work and a brighter one for games and video.
- Use full screen for long sessions. A full-screen app hides the menu bar and Dock, and its content changes as you work.
- Change your layout now and then. The same two windows split 50/50 every day for a year put the same edges and title bars in the same place. Swapping sides, or using a different split some days, spreads that out.
- Keep bright static things small. Pinned palettes, a white sidebar, a clock widget: anything that never moves and stays bright is what burns in first.
- Don't worry about games and video. Content that changes all the time is what OLED is best at. A HUD or a channel logo is the exception, and the monitor's logo dimming is there for it.
Where OLEDSnap fits
Everything above is free, and it's enough for most people. One gap is left: your monitor shifts the whole picture, but it can't move your windows, so a layout you keep for months still puts the same window edges in the same place.
I make OLEDSnap, a Mac window manager that covers that gap. It snaps windows with shortcuts or by dragging, and on OLED screens it moves each window 1 pixel every 5 minutes, only after you pause typing. It also lets window edges land a few pixels differently each hour. It doesn't move the menu bar or Dock (use the settings above), and no software can promise to prevent burn-in. $19 once, with a 14-day free trial.
