Should you hide the Dock to protect an OLED screen?

Yes, the Dock can contribute to OLED burn-in, but it is a smaller risk than the menu bar for most people. The menu bar is always on screen, always bright, and never moves. A Dock that auto-hides spends most of its life off screen, so it does far less damage. If you leave the Dock pinned and visible all day on a real OLED panel, treat it as a genuine risk and hide it too.

That is the short answer. The rest of this post explains why the Dock usually matters less than the menu bar, the few cases where it matters just as much, and the cleanest ways to deal with it on a Mac.

First, the burn-in basics

OLED burn-in is permanent. Each pixel on an OLED panel is its own tiny light source, and those lights dim as they age. When part of the screen shows the same bright image for thousands of hours, those pixels wear faster than their neighbors. Eventually you see a faint ghost of that shape everywhere, even on a solid color. That uneven wear does not heal.

Image retention is the temporary version. A static element can leave a faint afterimage that fades on its own within minutes or hours of normal use. Retention is annoying but recoverable. Burn-in is the permanent endpoint of the same process. We cover the full distinction in OLED burn-in vs image retention.

The thing that turns retention into burn-in is time, specifically time spent showing a bright, static, high-contrast element in a fixed spot. That description fits the menu bar perfectly. It fits a pinned Dock only partway.

Why the Dock is usually a smaller risk than the menu bar

The menu bar is the worst case for an OLED screen, and we explain exactly why in why an always-on menu bar is the worst thing for an OLED screen. Three things make it bad:

• It is on screen every second the Mac is awake.
• It is bright, usually a light strip with sharp black text and icons.
• It never moves. The clock, the icons, and the menu titles all sit in fixed pixels.

The Dock shares the brightness and the high contrast. Where it differs is duration and position.

Most Docks already auto-hide

If you have macOS set to hide the Dock (System Settings, Desktop & Dock, "Automatically hide and show the Dock"), it only appears when you push your cursor to the edge. That might be a few seconds at a time, a few dozen times a day. Compare that to the menu bar sitting there for eight straight hours. The Dock is getting a fraction of the exposure.

The Dock also moves more than you think

Its width changes as you open and close apps. Icons shift position. The whole thing can live on the bottom, left, or right edge. That movement spreads any wear across more pixels instead of hammering the same ones. The menu bar has none of that variety.

So if your Dock auto-hides, you have mostly solved the problem already. The bigger and more constant offender is the menu bar.

When the Dock is a real burn-in risk

There are specific setups where the Dock earns the same caution as the menu bar.

You keep the Dock pinned and always visible

If auto-hide is off and the Dock sits on screen all day, it is now a bright, static strip in a fixed location. That is the exact recipe for burn-in. On a pinned bottom Dock you are wearing the bottom rows of pixels, and over time the translucent Dock background and the row of app icons can ghost in.

Your icons rarely change

A Dock full of the same pinned apps in the same order, day after day, behaves like a static image. If you open the same five apps and never touch the rest, those icon positions barely move. The more your Dock stays identical, the more it acts like the menu bar.

You run a bright wallpaper or light mode

Burn-in tracks total light output over time. A pinned Dock over a bright desktop in light mode pushes those edge pixels harder than the same Dock over a dark wallpaper. If you want the gentlest setup overall, see best wallpaper and dark mode settings for an OLED Mac setup.

You are on an actual OLED panel

This caveat matters more than people expect. Most shipping Macs and Apple displays are not OLED. They use LCD or mini-LED, including the Pro Display XDR and the current MacBook Pro screens, and mini-LED does not suffer permanent burn-in the way OLED does. OLED on the Mac desktop almost always means an external monitor from a brand like LG, Samsung, ASUS, or Dough. If you are not sure what you have, check which Macs and Apple displays are actually OLED before you worry about any of this.

If your Dock auto-hides and your panel is mini-LED, you can stop reading. There is almost nothing to fix. The Dock burn-in question really only bites on a genuine OLED panel with a pinned, never-moving Dock.

How to tuck the Dock away

If you decided the Dock is a risk worth handling, here are the options, from simplest to most thorough.

Turn on the built-in auto-hide

This is the first thing to do, and it is free. Open System Settings, go to Desktop & Dock, and switch on "Automatically hide and show the Dock." The Dock now slides off screen and only returns when you move your cursor to its edge. For most OLED owners, this single toggle removes the Dock as a meaningful burn-in source.

There is one catch on a multi-display setup. The Dock lives on whichever screen your cursor last visited along that edge, so it can pop up on your OLED monitor when you do not want it there. Auto-hide still helps, since the Dock is hidden by default, but you cannot pin the Dock to your safe LCD and forbid it from the OLED through System Settings alone.

Speed up the reveal delay if it annoys you

Some people leave the Dock pinned because the auto-hide animation feels slow. You can remove the delay so the Dock appears the instant your cursor hits the edge. In Terminal, run defaults write com.apple.dock autohide-delay -float 0 && killall Dock. That often makes auto-hide pleasant enough to actually keep on.

Hide the Dock together with the menu bar

If you are already hiding the menu bar to protect an OLED screen, it makes sense to handle the Dock in the same place. TuckBar hides the system menu bar on the specific displays you tag, which is something macOS cannot do per display on its own, and it can hide the Dock at the same time. Your tagged OLED monitor loses both static bright strips, while your other screens keep their menu bar and Dock as normal. Tuck on a timer or reveal on hover when you actually need them.

That per-display angle is the whole reason a tool exists for this. Built-in macOS auto-hide is global. We get into why in why macOS can't hide the menu bar on just one display, and the same global limitation applies to the Dock.

The honest priority order

If you protect one thing, protect the menu bar. It is on screen longer, it never moves, and it is the element most likely to leave a permanent mark. Burning hours into the same menu-bar pixels is the fastest path to visible wear, which we look at in how long it takes for a static menu bar to burn into an OLED.

The Dock comes second. For most people, turning on auto-hide is enough. Only the pinned, always-visible, never-changing Dock deserves the full treatment.

And do not lose the plot. Burn-in is about total static exposure over thousands of hours. The menu bar, a pinned Dock, and a bright fixed wallpaper all add up. A Dock that lives off screen most of the day barely registers. Spend your effort where the pixels are actually wearing.
