Mirosoft has begun to make good on its promise of bringing improved visuals to games for its Xbox Series S and Series X consoles.

The company has started to offer Dolby Vision HDR gaming to members of the Xbox Insider's 'alpha ring' group. These testers are able to try out Xbox features before they are made available to the general public, in a bid to help Microsoft upgrade its consoles and their functionality.

Dolby Vision is a form of HDR (high dynamic range), but instead of merely cranking up the peak brightness, it contains metadata that adjusts the brightness of a display for each frame of footage.

Microsoft says how this makes for "brighter highlights, sharper contrast, and more vibrant colors". But, as with video content that uses Dolby Vision, a compatible television is required to see the difference. The two next-generation consoles currently support HDR10, which is a less advanced HDR standard.

Dolby announced back in September 2020 how the pair of Xbox consoles would be the first to support Dolby Vision HDR, with compatible games including dynamic metadata to adjust display brightness, color and contrast on the fly. Dolby Vision is not currently supported by the rival PlayStation 5 console.

Microsoft adds how the upgrade will "make it easier to see opponents hiding in the shadows and spot hidden clues through expanded contrast and better clarity in both light and dark scenes."

Dolby Vision for gaming is automatically configured for your display (as long as it is compatible, of course) and means no more need to adjust sliders to set brightness and contrast levels when launching a game for the first time.
