HDR10 vs Dolby Vision: what's the difference

HDR10 and Dolby Vision are both HDR (High Dynamic Range) formats, designed to widen the range of highlights, shadows and colors visible on screen compared to standard SDR content — but they work very differently, and the technical gap has real practical consequences on picture quality.

HDR10: the universal static standard

HDR10 is the most widespread HDR format, supported by virtually every HDR TV and piece of content on the market: it’s the baseline standard any HDR-capable device must guarantee. It’s a static standard: peak brightness and color gamut parameters are set once, via a single metadata block, for the whole movie or episode, without adapting scene by scene. This means a very dark scene and a very bright one in the same film get processed with the exact same baseline parameters.

Dolby Vision and HDR10+: the dynamic standards

Dolby Vision (proprietary to Dolby Laboratories, with a paid license required for every device produced) and HDR10+ (open and royalty-free, backed by Samsung and Amazon among others) are dynamic formats: they adjust HDR parameters scene by scene, or even frame by frame, via additional metadata embedded in the video file itself. This in theory achieves a more precise result that’s more faithful to the director’s intent than HDR10’s fixed parameters, especially in movies with strong brightness contrasts between different scenes.

HLG: the third format, built for broadcast

There’s also a third format, HLG (Hybrid Log-Gamma), jointly developed by the BBC and NHK specifically with live broadcasting in mind, where embedding complex dynamic metadata in real time isn’t feasible. Its main advantage is backward compatibility: an HLG signal stays watchable even on a TV without HDR support, still showing an acceptable SDR image instead of an error or washed-out picture.

Does the difference actually show?

In practice, the gap between HDR10 and the dynamic formats depends heavily on the panel’s peak brightness and overall quality: on a TV with limited peak brightness (under 400-500 nits, typical of budget tiers), the perceived difference between HDR formats is often marginal with typical sources (streaming, Blu-ray), because the panel doesn’t have the dynamic range to fully exploit even baseline HDR10 anyway. It becomes more noticeable on high-end panels with brightness above 1,000 nits, in light-controlled environments, and with content mastered at very high brightness — precisely the conditions we cover in our full guide on how to choose a TV.

Which one should you pick in a TV?

You can’t really choose: every TV supports a fixed set of HDR formats decided by the manufacturer, and it can’t be changed via software after purchase. In general, Samsung supports HDR10+ but not Dolby Vision (a business decision to avoid Dolby Laboratories royalties, not a technical panel limitation); LG, Sony, TCL and Hisense often support both dynamic formats on their mid-to-high-end models. If you’re not sure how much this actually matters to you, it’s not a criterion worth paying a lot extra for over other factors like the panel’s actual peak brightness.

Frequently asked questions

Do I need Dolby Vision if I only watch Netflix or Prime Video?

If your TV supports it and the content is available in Dolby Vision (many shows and movies are, on Netflix, Prime Video and Disney+), yes, the image benefits from more precise tone mapping. Without support, the content still plays, just in the standard HDR10 baseline included in the same file.

Why don't some Samsung TVs have Dolby Vision?

Samsung has historically chosen to support HDR10+ (a competing, open, royalty-free standard) instead of Dolby Vision, which requires a paid license from Dolby Laboratories for every device produced. It's a business decision, not a technical limitation of the panel.

What is HLG and when is it used?

HLG (Hybrid Log-Gamma) is a third HDR format built mainly for live broadcast, where embedding dynamic scene-by-scene metadata like Dolby Vision isn't practical. It's used, for instance, by some broadcasters for HDR sports coverage, and stays compatible even on non-HDR TVs, still showing a watchable SDR image.
