This makes Dolby Vision HDR easier to broadcast.ĭolby Vision HDR also has a higher brightness ceiling. It works with older versions of HDMI than HDR10, and it can be transmitted at the same time as standard dynamic range (SDR) content, which is what you're seeing if you watch a TV channel at home. Dolby Vision solves several issues that were preventing HDR content being easily broadcast. Despite the cost to use Dolby Vision, most leading TV manufacturers are making compatible TVs. Unlike with HDR10, TV manufacturers need to pay a fee to use Dolby Vision, and it uses dynamic rather than static metadata. The PS5, Xbox One S and Xbox One X games consoles are also compatible with HDR10. This includes streaming services, such as Netflix and Amazon Video, and film studios, including Sony, Universal and Warner Bros, which put out HDR10 ultra-HD Blu-rays. Every HDR-capable TV is compatible with it, as are most of the places HDR content comes from. Static metadata is stuck with its sunglasses either on, or off: it can't adjust. When you go back inside, you take them off again. You leave the house and the blaring sun has you reaching for your sunglasses to shield your eyes. Think of it as going outside on a sunny day. Static metadata can't, which means there's more chance of detail being lost when scenes get particularly bright or dark. Dynamic metadata can adjust the HDR on a scene-by-scene basis, based on the brightness of your TV, what's being displayed and the light in your room in some cases. Metadata is the information required to make a standard video file into an HDR video file. HDR10 uses static metadata, HDR10+ and Dolby Vision use dynamic metadata, Technicolor can use both, and HLG doesn't use either. One of the major differences between types of HDR boils down to whether they use static or dynamic metadata. The difference between the formats comes down to how they use metadata, which media players and studios support them, as well as other factors such as how easy they are to broadcast. All five are fundamentally doing the same thing: improving contrast and colour depth, particularly when it comes to very dark or bright scenes. These formats are: HDR10, HDR10+, HLG, Dolby Vision and Technicolor. There are six different HDR formats supported by different manufacturers.

HDR doesn’t just improve the TV's brightness. HDR essentially creates a greater dynamic range between the darkest blacks and brightest whites, with more subtle differences in tones in between.Īlthough 4K TV is great on its own, a 4K HDR picture will seem even brighter and more detailed, particularly with darker scenes in films and TV shows. If you’re a keen photographer, you may have heard of HDR before, but it works slightly differently with video. But 4K HDR picture quality isn’t guaranteed to be better than 4K alone – we’ve seen a few instances of washed-out highlights lacking detail during brighter scenes, and detail being lost in dark parts of the picture.īrowse all our TV reviews to find the very best HDR sets. The best TVs will plunge to deeper blacks and stretch to brighter whites when showing HDR content, giving you even better picture quality. 4K HDR sets start from around £400 – but is this technology as important as manufacturers and retailers tell you?Ĭontent is limited to ultra-HD Blu-rays, games consoles, and streaming services but the range of shows and movies on them is now quite broad. HDR, or High Dynamic Range, is a TV standard that allows screens to give you improved contrast, more accurate colours and more vivid pictures than regular sets.Īlmost all 4K TVs also support one of the HDR formats and you aren't paying extra for it.
