High Dynamic Range (HDR) has become a prominent feature in monitor marketing, promising enhanced contrast, brighter highlights, and more vibrant colours. However, HDR implementation varies dramatically between monitors, and many displays advertised as HDR-capable deliver underwhelming experiences. Understanding what HDR actually means, how to evaluate HDR performance, and whether it aligns with your needs can help you avoid disappointment and make a worthwhile investment when HDR genuinely enhances your experience.
What HDR Actually Means
High Dynamic Range refers to content and displays capable of reproducing a wider range of brightness levels than standard dynamic range (SDR). In practical terms, HDR enables brighter highlights, deeper blacks, and more detail in both bright and dark areas of an image simultaneously. When properly implemented, HDR creates images that appear more lifelike and impactful.
True HDR requires both content mastered in HDR and a display capable of reproducing it. HDR content is created with specific peak brightness targets and wider colour gamuts than SDR. The display must achieve sufficient brightness, contrast, and colour volume to faithfully reproduce the creator's intent. When either element is insufficient, the HDR experience suffers.
The key components of genuine HDR performance include peak brightness capability, local dimming for enhanced contrast, wide colour gamut coverage (typically DCI-P3), and 10-bit colour depth for smooth gradients without banding.
Understanding HDR Certifications
VESA's DisplayHDR certification program provides standardised tiers to help consumers evaluate HDR capabilities. However, these certifications vary enormously in what they guarantee:
DisplayHDR 400 is the entry-level certification, requiring only 400 nits peak brightness and basic colour coverage. Monitors at this level often provide minimal HDR improvement, with no local dimming requirement meaning contrast enhancement is limited. Many enthusiasts consider HDR 400 insufficient for a genuine HDR experience.
DisplayHDR 600 raises the bar with 600 nit peak brightness and requires local dimming, though implementation quality varies. At this tier, HDR becomes noticeably beneficial for content that supports it, though it remains a compromise compared to higher tiers.
DisplayHDR 1000 and DisplayHDR 1400 represent genuine premium HDR, requiring 1000+ nits peak brightness and sophisticated local dimming. Monitors achieving these certifications typically deliver excellent HDR experiences that showcase the technology's potential.
VESA also offers DisplayHDR True Black certifications for OLED monitors, recognising their perfect blacks and infinite contrast ratios that compensate for somewhat lower peak brightness compared to LED backlit LCDs.
Local Dimming: The Critical Component
Local dimming technology independently controls the brightness of different backlight zones across the screen. This enables HDR monitors to display bright highlights in one area while maintaining deep blacks in another, creating the enhanced contrast that makes HDR compelling.
The number of dimming zones significantly impacts HDR quality. Budget HDR monitors might have 8-16 zones, while premium displays feature 500-1000+ zones. More zones enable finer control, reducing "blooming" where bright objects cause adjacent dark areas to brighten inappropriately.
Mini-LED backlighting has advanced local dimming capabilities dramatically, packing thousands of smaller LEDs into the backlight array. Premium Mini-LED monitors feature zone counts in the thousands, approaching the per-pixel precision of OLED while achieving higher peak brightness.
OLED monitors represent the ultimate in local dimming, with every pixel independently controlled. This eliminates blooming entirely and enables perfect blacks with infinite contrast, though peak brightness limitations mean the brightest highlights may not match top-tier LCD monitors.
HDR for Gaming
Gaming has embraced HDR enthusiastically, with most modern AAA titles offering HDR support. When properly implemented, HDR gaming transforms the experience, making sunlit scenes more brilliant, fire effects more dynamic, and dark environments more detailed without washing out.
To enjoy HDR gaming on PC, you need Windows with HDR enabled, a compatible graphics card and driver, an HDR-capable monitor, and games that support HDR. The Windows HDR implementation has improved significantly since early versions, though some users still report better experiences keeping Windows in SDR mode and enabling HDR only for specific games.
Console gaming with PS5 and Xbox Series X provides excellent HDR support, with these consoles designed around HDR from the ground up. Games often include HDR calibration tools to optimise the experience for your specific display.
For gaming, monitors with DisplayHDR 600 or higher typically provide worthwhile HDR experiences. Lower tiers often don't justify enabling HDR over a well-calibrated SDR image.
HDR for Content Creation
Professional content creators working with HDR video require monitors that accurately display HDR content for editing and colour grading. This demands not just bright highlights but accurate colour reproduction across HDR colour spaces, consistent brightness calibration, and reliable HDR10 and potentially Dolby Vision support.
Professional HDR reference monitors from manufacturers like ASUS ProArt, Dell UltraSharp, and BenQ's professional lines offer colour accuracy certifications alongside HDR capabilities. These typically cost significantly more than consumer HDR monitors but provide the reliability professionals require.
For hobbyist creators, a good HDR monitor helps visualise how content will appear on HDR displays, though professional colour work still benefits from dedicated reference monitors.

Compare HDR MonitorsIs HDR Worth It for You?
The value of HDR depends heavily on your use case and the quality of implementation you can afford.
HDR is worth it if:
- You can afford DisplayHDR 600 or higher (or an OLED display)
- You regularly consume HDR content through streaming services, Blu-rays, or games
- You play HDR-supported games on PC or console
- You create or edit HDR video content
- You value impactful visuals and can appreciate the difference
HDR may not be worth it if:
- Your budget limits you to HDR 400 certification
- You primarily use your monitor for office work or non-HDR content
- You'd sacrifice panel quality, size, or other features to afford HDR
- You prefer consistent SDR calibration over variable HDR implementation
The Current State of HDR Monitors
HDR monitor technology has matured significantly, with genuine quality now available at various price points. Mini-LED backlit monitors have democratised excellent HDR performance, while OLED gaming monitors combine outstanding HDR with perfect blacks and instant response times.
Entry-level HDR remains problematic. Monitors advertising HDR 400 often use the specification as a marketing checkbox rather than meaningful feature. The cost difference between adequate and poor HDR is typically worth paying for those who value the technology.
For Australian buyers, genuine HDR monitors start around $700-800 for displays with meaningful HDR implementation. Premium HDR gaming monitors with Mini-LED or OLED technology range from $1,200 to $2,500 or more. Professional HDR reference monitors for content creation can exceed $4,000.
Conclusion
HDR represents a genuine advancement in display technology that, when properly implemented, delivers meaningfully enhanced viewing experiences. The key is understanding that HDR quality varies enormously between monitors, and entry-level HDR often fails to deliver on the technology's promise.
If HDR appeals to you, invest in a monitor that implements it well rather than settling for HDR as a checkbox feature. For many users, a well-calibrated SDR monitor remains preferable to a poor HDR display. But for those who can access quality HDR monitors and consume HDR content, the technology genuinely enhances gaming, movies, and content creation in ways that are difficult to return from once experienced.
