Steam Deck Client Beta Update – Custom Boot Animations

Valve just shipped out a new Steam Deck Client Beta that focuses on making it easier to set up custom bootup animations and adding a new automatic resolution picker for external displays:

Custom boot videos

• Added a new folder for custom boot and suspend animations in steamui/overrides/movies/
• Play custom boot animations in full screen

General

• Added a toggle allowing Steam Deck to automatically control the display resolution for external displays. When toggled on, Steam Deck will automatically adjust the resolution for best performance on higher resolution displays.
• Fixed issue with startup haptics
