To take full advantage of HDR, start by ensuring your device has a processor and graphics chip capable of HDR content. Common handheld game consoles like Steam Deck (LCD/OLED), ROG Ally, and ROG Ally X support HDR.
Next, choose a display that supports HDR10, the most widely supported HDR format in games, including popular titles like Red Dead Redemption 2, Horizon Zero Dawn, and Elden Ring.
When connecting your Steam Deck to an external monitor via a USB-C dock for Steam Deck, ensure the dock supports HDR output. If the dock does not support HDR, this feature will be completely disabled, regardless of your display and device capabilities. Ensuring your dock maintains HDR quality is crucial for the best visual experience.
Note: The HDR quality also depends on your display’s specifications, such as peak brightness, color depth, color space, local dimming capabilities, and black levels.
