Microsoft is expanding testing for a feature that should make games look better, at least on compatible TVs. Dolby Vision HDR, a feature that should, in the simplest terms, make bright colors brighter and dark areas darker, is arriving for Xbox Series X|S users that are part of Xbox Insider’s alpha ring.

Precisely, Dolby Vision HDR is a proprietary HDR format that promises boosted performance over other HDR options. According to Dolby, the format offers “brightness, contrast, color, and depth that goes beyond even traditional HDR games.”

The Xbox Series X|S will also be the only consoles with this tech available when it launches for Xbox Insiders. Dolby announced last year that, along with bringing its audio format Dolby Atmos to next-gen Xbox consoles, Dolby Vision would be arriving sometime in 2021.
