What Is HDR on a Monitor and If It's Worth It
Why DisplayHDR 400 is a weak certification, and where genuinely perceptible HDR begins.
HDR promises deeper blacks, more intense brightness, and more vivid colours — but before paying more for an "HDR" monitor, there's a real warning worth your attention.
Not everything labelled "HDR" delivers real HDR. The most common entry-level certification, DisplayHDR 400, is widely considered by the industry too weak to deliver a genuinely perceptible HDR experience — it requires brightness barely higher than a good regular panel, without requiring local dimming (key to real HDR contrast). Even worse are monitors that simply say "HDR" or "HDR Ready" with no specific DisplayHDR certification number — be especially wary of those.
Where genuinely noticeable HDR begins
According to most independent technical reviews, genuinely perceptible HDR starts at DisplayHDR 600 or higher, where local dimming and a wider colour gamut are already required — not just higher maximum brightness on the spec sheet.
How to check it yourself: VESA offers a free checking tool (DisplayHDR Test Tool) to confirm whether a specific monitor genuinely meets what it advertises, instead of relying only on the box's marketing.
Is it worth it for you?
If you're going to actively use it for watching HDR content (streaming, depending on the platform) or playing titles with good HDR support, a DisplayHDR 600 or higher genuinely adds a real improvement. If your main use is office work without specific HDR content, it isn't worth paying the premium just for the label.
Tip: before paying more for "HDR" on a monitor, look for the specific DisplayHDR certification (400, 500, 600...) on the actual spec sheet, not just the word "HDR" in the product's commercial name.
Frequently asked questions
Is DisplayHDR 400 fake HDR?
It isn't exactly fake, but it's widely considered too weak an entry-level certification to deliver a genuinely perceptible HDR experience compared to a good regular SDR panel.
What should I avoid when buying an 'HDR' monitor?
Be especially wary of monitors that only say 'HDR' or 'HDR Ready' without specifying a concrete DisplayHDR certification number (400, 500, 600...) — they usually offer very little real improvement.
Do I need HDR if I don't watch much specific content for it?
If your main use is office work or general tasks, it probably isn't worth the extra cost — HDR adds more real value when you actively use it for compatible streaming or gaming with good HDR support.
