HDR in Games: Real HDR vs Marketing HDR
HDR (High Dynamic Range) is a technology that makes the image look closer to what the human eye sees: bright sunlight is dazzling, details remain visible in the shadows, and colors appear richer. In practice, however, not every monitor labeled HDR delivers the real effect. The difference between genuine HDR and marketing HDR is enormous and comes down to brightness and local dimming. Below, we explain what HDR is, which formats exist, how real HDR differs from fake HDR, and what to look for when choosing a monitor.
In Brief: What You Need to Know
- HDR expands the range of brightness and color, allowing bright highlights and shadow detail to remain visible in the same frame.
- The format—HDR10, HDR10+, or Dolby Vision—determines the metadata, while panel brightness and local dimming determine the actual image quality.
- DisplayHDR 400 does not require local dimming, so its effect is weak. Real HDR starts at around DisplayHDR 600, comes into its own at 1000, and is at its best on OLED and Mini-LED displays.
What Is HDR?
A standard dynamic range (SDR) image is limited in brightness and color, so bright and dark parts of a scene have to be averaged. HDR expands this range, allowing bright light sources without washed-out highlights and deep shadows with visible detail to appear in the same frame, while also providing a wider color gamut. The key difference between HDR and SDR is not resolution or sharpness, but dynamic range and brightness. For a genuine HDR effect, a monitor must display very bright highlights and truly dark areas at the same time. This requires high peak brightness and the ability to dim the backlight locally in separate areas of the screen.
HDR Formats: HDR10, HDR10+, and Dolby Vision
HDR comes in several formats, and it is useful to understand the differences. HDR10 is the basic and most widely used format, with static metadata set for an entire movie or game. HDR10+ and Dolby Vision use dynamic metadata and adjust brightness for each scene, producing a more accurate result; Dolby Vision also supports color depth of up to 12 bits. HDR10 is most common in PC games, while Dolby Vision appears in selected titles and on consoles. It is important to remember that the format determines the metadata, while panel brightness and local dimming still determine the actual image. Even an advanced format cannot compensate for a weak monitor.
Real HDR vs Fake HDR
VESA DisplayHDR certification is a useful guide. Its number indicates peak brightness in nits, although nits are not the only factor that matters. DisplayHDR 400 is often called marketing HDR: it does not require local dimming, and 400 nits is not enough for a striking effect. The monitor accepts an HDR signal but displays an image only slightly better than a standard one. Real HDR begins where there is local dimming and sufficient brightness headroom. DisplayHDR 600 requires 600 nits and mandatory local dimming, while DisplayHDR 1000 with full-array local dimming delivers a complete HDR image with bright highlights and deep blacks.
| Level | Peak Brightness | Local Dimming | Color |
|---|---|---|---|
| DisplayHDR 400 | 400 nits | Not required | 95% BT.709, 8-bit |
| DisplayHDR 600 | 600 nits | Required (edge-lit) | 90% DCI-P3, 10-bit |
| DisplayHDR 1000 | 1000 nits | Full-array | Wide gamut, 10-bit |
HDR in Games
HDR is most noticeable in games during scenes with major differences in light levels: sunlight streaming through foliage, a neon-lit city at night, flashes, and explosions. On a good HDR monitor, such moments gain a sense of volume and depth that SDR cannot provide, while the difference is minimal in calmer scenes. To use HDR, enable it in two places: first in the Windows display settings, and then in the game's graphics settings, where available brightness sliders should be calibrated. One important detail is that a normal desktop can look washed out in HDR mode, so many users enable HDR only for games.
How to Choose an HDR Monitor
Two technologies deliver genuine HDR. OLED controls the light output of every pixel individually, producing perfect blacks and effectively infinite contrast; these panels also have a separate DisplayHDR True Black certification. Mini-LED uses a backlight made of thousands of miniature LEDs with numerous dimming zones, which also delivers bright, high-contrast HDR. When choosing a monitor, look beyond the HDR label and examine the specifics: the DisplayHDR level—preferably 600 or higher—the number of local dimming zones, peak brightness in nits, DCI-P3 coverage, and panel type. If the specifications list only HDR400 without local dimming, do not expect a pronounced effect.
Frequently Asked Questions We have prepared the answers.
- What is the difference between HDR400 and HDR600? DisplayHDR 400 requires a peak brightness of 400 nits but does not require local dimming, so its HDR effect is weak. DisplayHDR 600 requires 600 nits and mandatory local dimming, as well as a wider color gamut and 10-bit color. The practical difference is substantial: real HDR begins at around the 600 level.
- How does HDR10 differ from Dolby Vision? HDR10 uses static metadata set for the entire piece of content and is the most widespread format. Dolby Vision uses dynamic metadata to adapt the image for each scene and also supports color depth of up to 12 bits. HDR10 is more common in PC games, but the monitor itself still determines the final image quality.
- Do I need HDR for gaming? HDR is a welcome bonus rather than a requirement. Bright, high-contrast scenes look more impressive on a good HDR monitor, but refresh rate and resolution provide smoothness and clarity. If your budget is limited, it makes more sense to invest in those first and treat HDR as an additional benefit when the monitor has a good panel.
Conclusion
Real HDR requires high peak brightness and local dimming, while a DisplayHDR 400 label often offers little benefit. A format such as HDR10 or Dolby Vision determines the metadata, but the monitor itself determines the result. Look for DisplayHDR 600 or higher, and preferably OLED or Mini-LED. Remember that comfortable gaming depends not only on bright scenes, but also on refresh rate with adaptive sync. You can choose a suitable monitor and system from the HYPERPC catalog or build a configuration in the gaming PC configurator.
