HDR Gaming on PC: How to Set It Up Right, Including Auto HDR

HDR (high dynamic range) lets a screen show brighter highlights and deeper, more detailed shadows than standard dynamic range (SDR). On a poor setup, the same game looks gray, dim or glaring. The difference is mostly settings, so this guide walks through them in order.

What you need before you start

Microsoft says HDR needs a compatible HDR10 display and a PC that supports HDR and wide color gamut. Not every monitor that says "HDR" on the box does this well. If you are buying, look for a VESA DisplayHDR certification (a higher number generally means a better HDR experience), read independent reviews, and check current prices.

For the connection, Microsoft suggests DisplayPort over HDMI if your display supports HDR over DisplayPort, because color problems are more likely on HDMI. Keep your graphics drivers current: see updating graphics drivers safely.

Turn on HDR in Windows 11

1. Open Settings, then System, then Display.
2. If you have several displays, pick the HDR display at the top.
3. Turn on HDR.

Two traps catch many people:

• Duplicate mode on a laptop with an external monitor. Microsoft says HDR is not supported when the desktop is duplicated. In the same Display page, choose Extend these displays.
• HDR missing or greyed out. Turn HDR on in the monitor's own menu too (the steps depend on the maker). You can also press the Windows key and R, type dxdiag, and check the System tab. AdvancedColorSupported and AdvancedColorEnabled show whether your driver and display support HDR and whether it is on. On an HDR laptop, HDR may be turned off on battery by default, so plug in.

Fix the "everything looks dull" problem: SDR content brightness

Once HDR is on, your desktop and normal apps are still SDR content, and Windows has to map them into the HDR picture. If the desktop looks too bright or too dark, open Settings, System, Display, choose the HDR display, select HDR, and drag the SDR content brightness slider.

On an external display, this slider changes SDR brightness relative to HDR. Microsoft notes that the default value, or something close to it, usually works well. If desktop apps look too dark, lower the slider and raise the brightness in the monitor's on-screen menu instead.

If your monitor is Dolby Vision certified, you will also see Use Dolby Vision mode in the HDR section. Microsoft explains that some of these monitors limit peak brightness in that mode, and that a non-certified HDR10 mode may be brighter but less color accurate.

Calibrate with the Windows HDR Calibration app

Microsoft offers a free Windows HDR Calibration app in the Microsoft Store. It works on Windows 11 only, needs HDR turned on, and must run full screen. For good color saturation it also wants a fairly recent GPU: NVIDIA GTX 10xx or newer, AMD RX 400 series or newer, or Intel 11th gen or newer.

1. Turn off extra picture effects in your monitor's menu, because post-processing can interfere.
2. Sit in your usual lighting.
3. Open the app on the HDR display and work through its three test patterns, dragging each slider until the pattern is no longer visible. They find the darkest detail you can see, the brightest detail you can see, and the maximum brightness.
4. Set color saturation. Microsoft warns that pushing it too far makes HDR look unnatural.

Run it again whenever you change or add a monitor.

Auto HDR for older games

Many games are not made for HDR. Auto HDR is a Windows 11 feature that tries to add HDR to SDR games. Microsoft does not have a dedicated page for it that we could read, so the details below come from a hardware maker's guide (ROG) and describe one writer's testing, not a promise.

1. Open HDR settings from the Windows search bar and turn on Use HDR.
2. Turn on Auto HDR, which appears after that.
3. Start a game. A notification should show when Auto HDR is active.

The ROG guide says Auto HDR is aimed at DirectX 11 and DirectX 12 games and that there is no official compatibility list, so you may need to test each game. Results vary: some games improve clearly, others barely change.

Useful shortcuts from the same guide:

• Win + Alt + G turns HDR on or off quickly, so you can keep HDR off on the desktop and switch it on before a game.
• Win + G opens the Xbox Game Bar. In its settings, under Gaming Features, Adjust HDR Intensity lowers the effect. A lower value means less intense highlights, and it can be set per game.

Auto HDR: on or off, and what if it is too bright?

Should Auto HDR be on or off? Leave it on if you like the look, and turn it off if you do not. Because it is an automatic guess, some games look better and some look worse. If a game has its own native HDR option, use that instead of relying on a guess.

Auto HDR too bright? Try these in order:

1. Open Game Bar with Win + G and lower Adjust HDR Intensity for that game.
2. Lower SDR content brightness in Windows HDR settings. The ROG writer found low values worked best on a very bright display, but that depends on your monitor.
3. Check the monitor menu for brightness or HDR modes, and turn off extra effects.
4. If it is still wrong, press Win + Alt + G to turn HDR off while you play that game.

Common mistakes

• Leaving HDR on all day with a washed out desktop. Use Win + Alt + G, or fix the SDR brightness slider.
• Judging HDR on a monitor with weak HDR. Settings cannot add brightness the panel does not have.
• Using Night light with HDR. Microsoft lists over-saturated color as a known side effect.

Quick checklist

• HDR display, ideally on DisplayPort, with drivers up to date.
• Extend mode, not duplicate, if you have two screens.
• HDR on in Windows and in the monitor menu.
• SDR content brightness near the default, then adjusted to taste.
• Windows HDR Calibration app run once, with monitor effects off.
• Auto HDR tested per game, with HDR intensity lowered if needed.

For smoother motion on the same screen, read about V-Sync, G-Sync and FreeSync and monitor refresh rate. To see how sharp your screen is, try the monitor PPI calculator. GPU makers also offer their own HDR features, which we do not cover here.
