4K playback support
Steam Remote Play offers 4K support in beta and offers a host of presets for gamers that allow them to find the perfect high-resolution settings. Before this update, 4K was possible while playing remotely, but it required lengthy adjustment and was not working as usual. This issue has been fixed.
The new Steam Client beta update brought other innovations besides 4K playback support for Remote Play. Players can now resize the settings window, the back button works as it should, the transition from full screen to window mode when full screen is closed has been fixed, the freezing problem has been fixed.
