Set up HDR in Windows
Prepare the monitor, adjust Windows, and calibrate each game. If something looks wrong, identify the problem before changing more controls.
Start setupWhat setup can change
Good settings preserve highlight and shadow detail and avoid incorrect conversions. They do not increase the panel's physical contrast or eliminate reflections or halos. On a display with limited HDR, SDR may be preferable.
To understand brightness, contrast, and color, see HDR concepts. Here, we focus on getting it working.
1. Prepare the monitor and connection
Choose the mode you will use
In the monitor menu, select the HDR mode recommended in its review or manual. Keep that choice fixed during setup. Modes with different peak brightness or dimming behavior may need different settings.
Check the signal
Use native resolution and your desired refresh rate. Confirm that the GPU, port, and cable support that combination with HDR. If there are problems, try a lower refresh rate to isolate the connection; then return to your target.
For text, prioritize RGB or 4:4:4 when available. The bandwidth calculator helps compare modes, but does not certify hardware compatibility.
Enable HDR on the correct display
In Windows, open Settings → System → Display → HDR. If you have multiple monitors, first select the one you want to configure. Check the capabilities reported by Windows.
Menus and troubleshooting: Microsoft HDR documentation.
The path in Windows
Open Settings → System → Display. If you use multiple monitors, select the one you want to configure before opening HDR.

The SDR desktop has its own adjustment
With HDR enabled, Windows also displays SDR content. The SDR brightness control adjusts its level within that output; it does not set the monitor's HDR peak. Start with a comfortable brightness using a familiar SDR window. No single slider value works for every monitor.
If an application does not reflect the change, close and reopen it. If blacks are raised throughout the image, do not blame this control alone: check the signal and picture mode in troubleshooting.
2. Use Windows HDR Calibration
Microsoft's app for Windows 11 lets you adjust visible limits and create a profile. Run it full screen on the selected HDR display under your usual lighting.
Three patterns, three adjustments
Saturation and profile
Start without boosting saturation. Save the monitor name and HDR mode used; repeat the process if relevant settings change.
Patterns are drawn to help identify the stages, not to calibrate from this page. Make adjustments in Windows HDR Calibration, full screen. Microsoft instructions ↗︎
Do not simply copy the nits from a specification sheet: the pattern and monitor processing can produce a different threshold. If the pattern never disappears, check tone mapping and menu effects; Microsoft warns that post-processing can interfere.

What if the HDR mode always compresses highlights?
Some modes preserve the pattern by continually adapting it. Use the mode or procedure specified by the manufacturer or the model's review. Do not enter an extreme value just to make the pattern disappear. The app is a visual aid; it does not measure the screen with a sensor.
3. Adjust each game's HDR
The Windows profile does not force every game to use the same limits. If a game has its own HDR controls, check maximum brightness, reference white, and black level. Names and scales vary.
Enable the game's HDR and calibration.Check highlights, shadows, and interface brightness.
Try Auto HDR or RTX HDR if supported.Evaluate the result and performance impact.
Look for a fix specific to that game.Check the version, compatibility, and how to undo it.
Enable only one SDR → HDR conversion. When comparing solutions, keep the same scene and change one thing at a time. More brightness or saturation does not prove that information the game never produced has been recovered.
If the image does not look right
Start by determining whether it happens throughout Windows, in just one application, or only in one game.
The desktop looks dull, but HDR content looks good
Adjust SDR content brightness in Windows and restart the application if it does not respond. Also check whether you are comparing SDR against an earlier oversaturated mode. Do not raise a game's HDR peak to brighten the desktop.
Blacks look gray throughout the image
Check that the GPU's output range matches the range the monitor expects. A full-versus-limited mismatch can alter blacks and whites. Check the monitor mode, local dimming if available, and light falling on the panel. If only one app is affected, check its HDR handling.
Detail is lost in clouds, fire, or reflections
Highlights may be clipping. Repeat the game's calibration using its pattern, check the limit used, and compare the monitor's tone mapping mode. Just because a control allows 4,000 nits does not mean you should select that value.
There are halos or the whole screen's brightness changes
Halos may come from zone dimming; brightness changes can also result from power limits or scene handling. Compare modes and content before blaming Windows. Calibration does not add zones or eliminate the panel's physical behavior.
Only one game looks washed out or oversaturated
Disable conversions and filters to test native HDR first, or SDR if it has no HDR. Check its calibration and restart the game after changing HDR in Windows. If it persists, look for instructions for that specific version; a generic profile does not fix every implementation.
The screen goes black, loses signal, or will not let you enable HDR
Check the cable, port, and combination of resolution, Hz, and color depth. Try a direct connection without an adapter and a less demanding mode. This helps distinguish a transport problem from a brightness or color issue.
Advanced profiles and tools
A profile describes or adjusts part of color reproduction; it does not transform the panel's physical capabilities. Nor do all applications use it the same way. Visual HDR calibration does not replace color-accuracy measurements.
ICC profiles and instrument calibration
Keep the original profile so you can restore it, and use profiles appropriate to your display and mode. For demanding color work, define the target, measure, calibrate, and validate with suitable software and instruments. Copying another unit's ICC does not guarantee the same result.
Windows distinguishes traditional color management from Advanced Color. Microsoft's documentation explains how they relate.
RenoDX: game-specific modifications
RenoDX uses ReShade's add-on system to modify parts of rendering. Some modifications fix or expand HDR, but check the game's entry: it is not a universal switch for every title. Follow the author's instructions and requirements, and check the game's restrictions first if it uses anti-cheat protection.
Special K: another option for supported games
Special K offers tools for adjusting and adding HDR. Use it as an alternative when its documentation covers your game and version. Save a recoverable configuration and compare without other HDR filters active. Do not assume compatibility with protected or multiplayer games.
HDR on Linux
It depends on the graphical session, drivers, and applications, not just the distribution. Plasma 6.4 added an HDR calibration wizard; GNOME 48 introduced system-level HDR support. Having HDR output does not mean every application delivers HDR content.
Games, Gamescope, and SteamOS
In environments such as SteamOS, Gamescope participates in game presentation. Desktop and gaming modes may follow different paths. Check the documentation for your version and game before copying launch parameters from another setup.
Choosing a monitor for HDR
Evaluate black levels, brightness by window size and its stability, color, and performance in real scenes. A certification provides a reference, but does not tell the whole story.
VESA publishes the DisplayHDR and True Black criteria. Check the family, level, and test version; “HDR 1000” in a menu does not by itself certify that label.
