“HDR” is printed on almost every gaming monitor box now, and that is exactly the problem. The same three letters cover displays that produce a genuinely striking image and displays that look, at best, like a slightly washed-out version of standard range. The label tells you a feature exists. It doesn’t tell you whether the hardware behind it can deliver what HDR is supposed to deliver. This guide extends the HDR section of our gaming monitor buying guide into the full decision.

What HDR is actually supposed to deliver

High dynamic range is about the distance between the darkest and brightest parts of an image, shown at the same time. A good HDR image can put a bright sun, a glowing muzzle flash or a neon sign next to deep shadow without crushing either end. Three hardware properties decide whether that happens:

  • Peak brightness. How bright small highlights can get. Highlights are where HDR is most visible.
  • Black level and contrast. How dark the screen stays next to those highlights. Brightness without dark blacks just makes the whole image brighter, not more dynamic.
  • Color volume. How much of a wider color range the display can show, and whether it keeps those colors accurate at high brightness.

A display that is weak on any of the three can still accept an HDR signal. It just can’t show what that signal contains. That gap between “accepts HDR” and “displays HDR” is the whole story of HDR labeling.

What the DisplayHDR tiers actually require

The most common certification on PC monitors is VESA’s DisplayHDR program. Its current test specification is CTS 1.2, published in May 2024. Each tier sets minimum requirements; the number in the name is the minimum peak brightness in nits (cd/m²). The figures below are VESA’s published minimums from displayhdr.org, not measurements of any specific monitor.

Tier Min. peak brightness Max. black level Color gamut Local dimming
DisplayHDR 400 400 nits 0.4 nits 90% DCI-P3 Not required (native panel or 1D)
DisplayHDR 500 500 nits 0.1 nits 95% DCI-P3 1D minimum
DisplayHDR 600 600 nits 0.1 nits 95% DCI-P3 1D minimum
DisplayHDR 1000 1000 nits 0.05 nits 95% DCI-P3 2D minimum
DisplayHDR 1400 1400 nits 0.02 nits 95% DCI-P3 2D minimum
True Black 400 / 500 / 600 / 1000 / 1400 400 to 1400 nits 0.0005 nits 95% DCI-P3 Advanced dimming (in practice, per-pixel panels such as OLED)

Two rows of that table matter most to buyers.

DisplayHDR 400 allows a black level of 0.4 nits without any local dimming. In practice that means an ordinary edge-to-edge backlit panel can qualify. It can get a bit brighter than a typical SDR monitor, but it can’t make dark areas darker while highlights get brighter, which is the core of the HDR effect. Many people who turn HDR on with an HDR400 monitor find the image looks flatter or greyer than SDR, and switch it back off. That’s not a setup mistake on their part; it is what the tier allows.

The True Black tiers require a maximum black level of 0.0005 nits, 800 times lower than DisplayHDR 400 allows. That is a requirement self-emissive panels such as OLED are built to meet, because each pixel can switch off completely. Their peak brightness numbers are lower than the top LCD tiers, but their contrast is in a different category.

Why the same tier can look very different

A certification is a floor, not a description. Two DisplayHDR 1000 monitors both meet the minimums, but how many local-dimming zones they have, how well those zones are controlled, and how they handle bright objects on dark backgrounds can differ a lot. On LCDs with zone-based dimming, a small bright object on a dark background can produce a visible glow (“blooming”) around it, because one zone is lit to serve one small highlight. More zones and better dimming algorithms reduce it; the certification number alone won’t tell you how well a given model does.

The same applies in reverse to OLED: True Black monitors can show perfect blacks next to bright highlights with no blooming, but full-screen brightness is usually well below their small-highlight peak. A bright snow level or a white desktop can look dimmer than on a strong LCD. That’s one of the real tradeoffs covered in OLED vs IPS for gaming.

Which tiers are worth paying for

Treat it as three branches rather than a ladder:

  • DisplayHDR 400 (and uncertified “HDR-ready” monitors): don’t pay extra for HDR. Buy the monitor for its refresh rate, resolution and SDR image quality. If HDR turns out to look good to you on it, that’s a bonus; it shouldn’t be the reason for choosing it.
  • DisplayHDR 600 to 1000 on LCD with real local dimming: worth it if HDR games matter to you. This is where HDR starts to look clearly different from SDR. Check the number of dimming zones and look for independent measurements of blooming before trusting the tier name.
  • True Black (OLED): the strongest HDR contrast you can buy in a monitor. Weigh it against OLED’s own tradeoffs: price, full-screen brightness limits and burn-in considerations for static desktop use.

If your budget only stretches to an HDR400 monitor, spending it on better refresh rate or a good VRR implementation usually changes your day-to-day experience more than the HDR label will.

HDR also depends on the game and the system

Good hardware is only half of it. HDR results also depend on:

  • The game’s own HDR implementation. Some games include an HDR calibration screen with peak-brightness and paper-white sliders; use it. Others have weaker implementations, and SDR can genuinely look better in them.
  • Your operating system. On Windows 11, Microsoft’s free Windows HDR Calibration app lets you set your display’s real brightness limits so games and Auto HDR tone-map to what your monitor can actually show.
  • Consoles and TVs. Console HDR setup is handled at the system level (PlayStation and Xbox both include HDR calibration screens), and many TVs offer a game-oriented HDR tone-mapping mode such as HGIG, defined by the HDR Gaming Interest Group, which lets the console’s calibration control tone mapping instead of the TV.

If you only play games without HDR support, or mostly use the monitor for desktop work, HDR isn’t a reason to spend more at all.

A quick decision check before buying

  1. Do the games you actually play support HDR well? If not, skip the HDR premium.
  2. Which tier is it, exactly? “HDR” or “HDR-ready” without a tier tells you nothing. HDR400 alone is not a reason to buy.
  3. LCD: how many dimming zones, and how bad is the blooming? Look for independent measurements, not the box.
  4. OLED: are you OK with lower full-screen brightness and burn-in precautions? If yes, it’s the strongest HDR experience on a monitor.
  5. Would the same money buy a bigger upgrade elsewhere? Sometimes the better choice is a GPU, not a display — see monitor or GPU first.

HDR done well is one of the most visible upgrades in modern gaming. HDR done as a checkbox is one of the most misleading. The certification tier, the panel type behind it and the games you actually play decide which one you’re buying.
