In December 2023, a significant update was released for chiaki4deck, an open-source tool that enables game streaming from PlayStation consoles to the Steam Deck via the PlayStation Remote Play feature. This update notably introduced support for High Dynamic Range (HDR) mode on the Steam Deck, which boasts an OLED display. This enhancement allows users to stream games from the PlayStation 5 while retaining HDR quality, a feature not available on Sony's PlayStation Portal device due to its non-HDR screen.
The developers of chiaki4deck have provided detailed instructions on GitHub for users to set up HDR game streaming. It's important to note that this HDR streaming feature is exclusive to PS5 games. Additionally, while the original Steam Deck can support this feature, it requires an external HDR display for optimal functionality.
This update is a considerable leap in game streaming technology, allowing Steam Deck users to experience PS5 games with enhanced visual quality, previously unavailable in portable formats.
