Dolby Vision Gaming Dolby Vision for Gaming (dynamic-metadata HDR for games)

What Dolby Vision Gaming is

Dolby Vision Gaming applies the Dolby Vision dynamic-metadata format to real-time game output. Xbox Wire announced it for Xbox Series X|S on September 28, 2021, with "more than 100 next-gen HDR titles optimized for Series X|S" available or coming soon in Dolby Vision. Dolby's own Xbox page says the Series X|S are "the first consoles to support gaming in Dolby Vision and Dolby Atmos." Wikipedia's Dolby Vision article separates the older Xbox One X and S, listed for streaming apps only, from the Series X|S, listed for streaming apps and gaming. Dolby Vision as a format allows up to 12-bit color and 10,000 nits of peak brightness, though current screens cannot show that range.

How Dolby Vision Gaming works

Movies and games differ in when the metadata is made. A film is graded in post-production. A game renders frames live, so the console has to produce the picture and tone-map it for the display in real time. Semtech's technical notes describe the Dolby mode built for this: the low-latency mode in the Dolby Vision HDMI transmission specification, version 2.9, moves "the computationally intensive task of processing metadata and tone mapping into the source." The signal is "native 12 bits 4:2:2 up to UHD resolution," with a D65 white point, BT.2020 matrix, and SMPTE 2084 transfer function. Dolby has carried Vision metadata across HDMI since version 1.4b. The pages I fetched for Xbox do not state which transport the console uses, so treat the low-latency mode as the format's documented route, not a confirmed Xbox detail. For the player-led mode in detail see player-led Dolby Vision (LLDV).

The bandwidth is modest at that format. Active data for 3840 x 2160 at 120 Hz with 12-bit 4:2:2 (24 bits per pixel) is about 23.9 Gbit/s, and at 60 Hz it is about 11.9 Gbit/s. Wikipedia's HDMI article puts HDMI 2.1 FRL at 48 Gbit/s with about 42.0 Gbit/s of data, and says formats above 18.0 Gbit/s may need an Ultra High Speed cable. That is why 4K at 120 Hz in Dolby Vision needs an HDMI 2.1 port and cable. See HDMI 2.1 and the HDMI cable tool.

Dolby Vision Gaming vs HDR10

HDR10 uses static metadata, a single set of values for a whole title, and 10-bit video, which is 1,073,741,824 colors. Dolby Vision can describe 12 bits, or 68,719,476,736 colors, and changes its mapping per frame. On a disc, the Dolby authoring guide shows the 12-bit idea in practice: a 10-bit HDR10 base layer plus a 10-bit enhancement layer reconstructs 12 bits and a master "as high as 4000 nits." Gaming cannot use that two-layer scheme live, so the value is the dynamic mapping, not bit depth alone. Games without Dolby Vision still benefit from HDR10, and Xbox Wire says thousands of other titles get HDR10 or Auto HDR treatment. See static vs dynamic HDR metadata and HDR10.

The format fight has a second contender. HDR10+ Technologies says HDR10+ Gaming "extends the same dynamic, scene-by-scene approach to real-time content," with certified support on Samsung OLED and Neo QLED TVs and PC gaming monitors. See HDR10+ Gaming.

Which platforms and TVs support it

Xbox Series X|S is the shipping case. Xbox Wire says Dolby Vision works with ALLM, VRR, and "up to 120FPS depending on the capabilities of your TV," and that Microsoft and Dolby were working with TV makers on firmware to support Dolby Vision at 120 Hz where possible. It cites "many 2020 and 2021 TVs, along with a select number of older TV models," as having the needed features, and points to Dolby's list for the current models. It also warns that a TV not optimized for the mode may add latency and advises checking for a firmware update. No source I fetched publishes an input-lag figure in milliseconds for the mode, so verify with a measurement for your TV.

PlayStation 5 is the gap. A December 2021 report answered "no" to Dolby Vision on the console, and I found no Sony announcement since, including for PS5 Pro. Treat that as a point-in-time answer and check Sony's current documentation. I also found no fetched primary source for Dolby Vision game support on Windows PC. Wikipedia lists Windows 10 and 11 built-in media players with the Dolby Vision Extension for video profiles 4, 5, 8, and 9, which covers playback, not games.

Turning it on

On Xbox, press the Xbox button and go to Settings > General > TV & display options > Video modes > Dolby Vision for gaming. To check what the TV reports, open 4K TV details in the same menu. Turn on ALLM and VRR at the TV, and update both console and TV firmware. A TV that is not Dolby Vision-capable will not offer the setting. For TV picks see best TV for gaming, and for the wider setup gaming vs movie setup.

Common confusions

Dolby Vision Gaming is not the same thing as Dolby Vision on a Blu-ray, even though both carry the same brand. It is not an automatic quality upgrade: the game has to be authored for it, and the 100-plus count dates from launch, not today. And the presence of a Dolby Vision logo on a TV says nothing about its latency in this mode. ALLM and VRR are separate HDMI features that have to be on alongside it.
