HDR on PC is one of those settings where doing it halfway is often worse than not doing it at all. Enable HDR in the wrong order, skip the Windows calibration step, or enter the wrong in-game peak brightness value and you end up with washed-out colours and a blinding white desktop. This guide walks through every step in the correct sequence — Windows setup, calibration, in-game configuration, and the fixes for the most common problems. For context on whether HDR is worth enabling for your specific display, see our HDR gaming guide, which covers display tiers, Auto HDR, and RTX HDR in detail.
Before You Start: What You Actually Need
PC HDR requires three things to work correctly. Miss any one of them and the output will look wrong regardless of how carefully you configure the settings.
| Requirement | Minimum Standard | Why It Matters |
|---|---|---|
| HDR-capable display | DisplayHDR 600 or better | DisplayHDR 400 has no local dimming and 400-nit peak — HDR will look flat |
| Cable and port | DisplayPort 1.4 or HDMI 2.0b | Older cables cannot carry HDR metadata at higher resolutions |
| Windows HDR enabled | Windows 10 1703 or Windows 11 | HDR must be on at the OS level before any game or driver setting works |
If your display is only DisplayHDR 400 certified, HDR is typically not worth enabling for gaming. The spec requires only 400 nits peak brightness with no mandatory local dimming — the result is a low-contrast panel with a washed-out tone curve that looks worse than a well-calibrated SDR display. Check your monitor’s spec sheet before proceeding. If in doubt, the PC game settings explained guide includes a section on what display specifications mean in practice.
Step 1 — Enable HDR in Windows
Windows HDR is controlled at the system level, not per-application. You must turn it on here before any game or the GPU driver can output HDR signal.
- Right-click the desktop and select Display settings.
- Select your HDR-capable monitor from the display list (if you have multiple monitors).
- Scroll to HDR and click it to expand the section.
- Toggle Use HDR to On.
- Optionally enable Auto HDR if you want older SDR-only games to receive HDR tone mapping automatically (see the Auto HDR section below).
After enabling, your desktop may look slightly washed out or have different white balance than before. This is expected — Windows is now driving the display in HDR mode and the desktop SDR content is being tone-mapped into HDR space. The calibration step in Step 2 corrects this.
Important: If your monitor has multiple inputs, make sure Windows HDR is enabled on the correct input. Enabling it on HDMI 1 while your PC is connected to HDMI 2 will show no effect.
Step 2 — Calibrate With the Windows HDR Calibration App
Windows 11 includes a dedicated HDR calibration tool that sets the correct brightness mapping between your SDR desktop and your display’s HDR capability. Without this step, SDR content (including the Windows interface itself) will look either over-bright or washed out in HDR mode.
- Open the Start menu and search for Windows HDR Calibration. The app is built into Windows 11 (and available as a free download from the Microsoft Store on Windows 10).
- Ensure the room lighting matches your normal gaming conditions before starting — calibration is environment-dependent.
- Follow the on-screen prompts. The app displays a series of test patterns and asks you to adjust a slider until specific elements just become visible or disappear.
- The key calibration point is SDR content brightness — this controls how bright the Windows desktop and SDR applications appear when HDR is active. Set it so white UI elements look natural, not blinding.
- Save the calibration. Windows applies it automatically whenever HDR is enabled on that display.
Run this calibration once per display. You only need to redo it if you change your room lighting significantly or get a new monitor.
Step 3 — Configure In-Game HDR Settings
Most games with native HDR support include two settings: Peak Brightness and Paper White Brightness. Getting these right is where the majority of HDR problems originate.
Peak Brightness
This value tells the game’s HDR tone mapper how bright your display can get at its maximum luminance output. Enter the wrong number and specular highlights will either clip to white (value too low) or stay dull (value too high).
Find your display’s peak brightness in the spec sheet. Common values:
| Display Tier | Typical Peak Brightness | What to Enter |
|---|---|---|
| DisplayHDR 400 | 400 nits | Skip HDR — not worth enabling |
| DisplayHDR 600 (LCD) | 600–700 nits | 600 |
| DisplayHDR 1000 (LCD) | 1,000–1,400 nits | 1000–1200 |
| WOLED (LG C/G series) | ~800–1,000 nits at 10% APL | 800 |
| QD-OLED (Samsung, Alienware) | ~1,000–1,300 nits at 10% APL | 1000 |
Use the full-screen sustained brightness figure, not the 1% or 10% APL peak spec. Games rarely sustain peak brightness across the full screen, but entering the absolute peak value causes highlight clipping in scenes with moderate brightness distribution.
Paper White Brightness
Paper White sets the brightness level that the game treats as 100% SDR white — effectively the brightness of a white piece of paper in a normally lit scene. This controls how bright the entire image looks, not just the highlights.
The correct value depends on your display and your room lighting:
- Dark room gaming: 80–100 nits. Higher values will make the image uncomfortably bright in darkness.
- Normal room lighting: 150–200 nits. The standard default used by most console HDR implementations.
- Bright room or near window: 200–250 nits.
If the image looks too bright overall, lower Paper White. If the image looks flat or dim, raise it. This is the most impactful single number for overall HDR image quality in everyday gaming conditions.
Auto HDR, Native HDR, and RTX HDR — Which to Use
Windows 11 and NVIDIA’s driver offer HDR modes that work on games without native HDR support. Here is when to use each:
| Mode | Works On | Quality | Performance Cost | Best For |
|---|---|---|---|---|
| Native HDR | Games with built-in HDR support | Best — developer-tuned tone mapping | None | All HDR-capable games |
| Auto HDR (Microsoft) | DirectX 11/12 games without native HDR | Good — AI-based highlight expansion | Effectively zero | Older titles, Xbox Game Pass catalogue |
| RTX HDR (NVIDIA) | Any game on RTX GPU via NVIDIA App | Good — driver-level tone mapping | Minimal | Games not covered by Auto HDR |
If a game has native HDR, disable both Auto HDR and RTX HDR and use the in-game settings directly — layering multiple HDR processing passes produces tone-mapping artefacts. If a game has no native HDR, Auto HDR is the first choice on Windows 11 for DirectX titles; RTX HDR is a good fallback for NVIDIA GPU owners on titles that Auto HDR does not pick up. For upscaling settings that interact with HDR rendering, the DLSS vs FSR vs XeSS guide explains how upscaling affects HDR image quality.
Common HDR Problems and Fixes
Washed-Out Colours After Enabling HDR
Cause: the Windows HDR mode is active but calibration has not been run, or Paper White is set too high.
Fix: run the Windows HDR Calibration app (Step 2 above). In-game, lower Paper White brightness by 20–30% from its default.
SDR Desktop Looks Too Bright When HDR Is On
Cause: Windows is tone-mapping SDR desktop content into HDR space at full brightness.
Fix: in Display Settings → HDR, reduce the SDR content brightness slider. The Windows HDR Calibration app sets this correctly if you have run it.
HDR Game Looks Like SDR
Cause: the game launched before Windows HDR was enabled, or the game is detecting the display incorrectly.
Fix: enable Windows HDR first, then launch the game. Some games require HDR to be active at launch to detect it. Also verify the game’s graphics settings have HDR explicitly enabled — many games default HDR to Off even on HDR-capable systems.
Black Crush — Shadow Detail Disappears
Cause: the game’s gamma or black level setting is miscalibrated for HDR, or the display’s local dimming is aggressively blocking near-black areas.
Fix: raise the game’s black level or gamma setting slightly. On OLED displays, try reducing the local dimming intensity setting in the monitor’s OSD.
Competitive Games — Should You Disable HDR?
Yes, for most competitive titles. HDR mode introduces a small but measurable input latency increase compared to SDR mode on most displays, because the HDR pipeline includes additional tone-mapping processing. In fast-paced competitive games (CS2, Valorant, Apex Legends), disable Windows HDR entirely while playing. Use an HDR desktop shortcut toggle (Win + Alt + B on Windows 11) to switch quickly without navigating menus.
FAQ
Does enabling HDR affect FPS?
Minimal impact for native HDR — the tone mapping runs on dedicated display hardware. Auto HDR and RTX HDR have effectively zero FPS cost on modern hardware.
Should HDR be on or off when using DLSS or FSR?
HDR and upscaling are compatible. DLSS and FSR both support HDR input and output. Enable HDR in the game’s settings alongside whichever upscaler you are using — they do not conflict.
Why does my HDR look better in one game than another?
Native HDR quality varies significantly by developer implementation. Some studios invest heavily in HDR calibration and tone mapping; others ship minimal HDR support. Games with no dedicated HDR calibration option typically produce mediocre results regardless of your display quality.
Can I use HDR on a 60Hz monitor?
Yes. HDR support and refresh rate are separate specifications. A 60Hz HDR display will output HDR content correctly at 60Hz. However, most DisplayHDR 600+ certified monitors also support higher refresh rates — check your monitor’s spec sheet.
