Turn on HDR for expanded brightness range and color in supported content
HDR (High Dynamic Range) lets a compatible monitor display a wider range of brightness and color than standard SDR content, producing brighter highlights and deeper shadows in games, video, and photos that were mastered for HDR.
What you should know
- Windows: Settings → System → Display → toggle "Use HDR" on for the connected monitor (only appears if both the monitor and the connection support it).
- Windows 11: after enabling HDR, open "HDR settings" and use the "HDR/SDR brightness balance" slider — without this adjustment, everyday SDR content like websites and documents can look washed out or dim once HDR is on.
- macOS: System Settings → Displays → select the monitor → enable "High Dynamic Range" if the option is present; not all macOS versions or Mac models expose this toggle for third-party HDR monitors.
- Confirm the monitor's own OSD has HDR enabled or set to "Auto" — many monitors require HDR to be turned on both in the OS and in the monitor's own picture-mode menu before it actually activates.
- Verify the cable and port support the required bandwidth (HDMI 2.0a or newer for 4K HDR at 60Hz, HDMI 2.1 or DisplayPort 1.4 for higher refresh rates) — insufficient bandwidth can cause the HDR toggle to fail silently or force a lower resolution/refresh rate.
Many budget monitors are only certified to the entry-level "DisplayHDR 400" tier, which has no local dimming and limited peak brightness — on these panels, HDR content can actually look flatter than well-tuned SDR, so it's worth comparing both before assuming HDR is strictly better on a given monitor.
Why it matters
HDR support varies enormously between monitors even within the same marketing tier, so knowing where to enable and calibrate it — and recognizing when a specific monitor's HDR implementation isn't strong enough to be worthwhile — prevents chasing a setting that a given panel can't meaningfully deliver on.
Best practices
- Adjust the HDR/SDR brightness balance slider immediately after enabling HDR in Windows; skipping this step is the top reason people conclude HDR "ruins" their screen and turn it back off.
- Enable HDR only when watching HDR-mastered content or playing HDR-capable games if your monitor's SDR-under-HDR handling looks poor — toggling it off for regular desktop use avoids the washed-out look entirely.
- Check both the OS-level toggle and the monitor's own OSD HDR setting — a mismatch between the two is the most common reason HDR appears to do nothing.
Common problems and fixes
- HDR toggle is missing in Display settings
- Confirm the monitor is DisplayHDR/HDR10 certified, that the cable and port support the needed bandwidth, and that you're connected via HDMI 2.0a+ or DisplayPort 1.4+ rather than an older cable or a USB-C dock that doesn't pass through full bandwidth.
- Everything looks dim or gray after turning HDR on
- Open Windows HDR settings and raise the "HDR/SDR brightness balance" slider, or check the monitor's OSD for a separate HDR brightness/peak-brightness setting.
Tips and tricks
- Use the built-in Windows "HDR Calibration" app (search Start menu for "HDR Calibration") to fine-tune peak brightness, black level, and color values specifically for your monitor's HDR mode.
Frequently asked questions
Does HDR affect refresh rate or resolution?
It can, indirectly — HDR at high resolution and refresh rate together may exceed a cable or port's bandwidth, forcing the system to drop resolution, refresh rate, or color depth (chroma subsampling) to compensate.
Related settings
- Set Native Resolution & Refresh RateEvery LCD panel has one native resolution where each pixel maps 1:1 to the signal, and a maximum refresh rate that depends on both the panel and the cable/port carrying the signal. Running below native resolution or refresh rate leaves clarity or motion smoothness on the table that the hardware is capable of.
- Set a Color Profile & Calibrate ColorColor accuracy depends on the operating system knowing how a specific monitor renders color, which is what an ICC profile describes. Both Windows and macOS include a manual calibration wizard, and either OS can load a manufacturer- or measurement-tool-generated ICC profile for more precise results.

- Adjust Brightness & ContrastBrightness and contrast on most external monitors are controlled by the monitor itself, not the operating system, through its on-screen display (OSD) menu — unlike a laptop's built-in screen, which the OS controls directly.
- Arrange Multiple DisplaysWhen more than one monitor is connected, the OS needs to know how they're physically arranged relative to each other so the cursor moves in the direction you expect when it crosses from one screen to the next.
- Configure Power Saving & Auto-Sleep BehaviorExternal monitors generally follow the power-management signal sent by the computer's graphics output — when the OS blanks the screen or the system sleeps, the monitor drops into a low-power standby state, separate from any power-saving timer set on the monitor itself.
