A special called “Steam Deck Refresh Rate Extender” is available for download online. It expands screen refresh capabilities to 70 Hz for the standard LCD model and 120 Hz for OLED models from BOE and SDC.
It is stated that the change has not yet been tested on models with Samsung panels.
According to recent reports, the new version of Steam Deck works smoothly, but brightness and gamma issues may occur at refresh rates above 110Hz.
At the same time, increasing the screen refresh rate has almost no effect on battery life; This makes this change attractive for streaming games, indie projects, and older games that can support high frame rates across device specs.
