The Deck stays
at native resolution.

The iPad upscales that frame to its Retina display, and to the OLED panel when the iPad Pro has one. The cable carries the picture, and the Wi‑Fi in the room is not involved.

Steam Deck with the game picture

On the Deck

The game renders at native resolution, the Deck’s own size. The Deck does not draw a bigger frame.

01

On the cable

One USB‑C cable carries the picture. Hotel Wi‑Fi, train Wi‑Fi, and no Wi‑Fi at all are the same to the picture.

On the iPad

MetalFX upscales the native resolution to take advantage of the Retina display. On an OLED iPad Pro, that is the Ultra Retina XDR panel. CAS and bilinear are there too. The frame stays 16:10, or it fills the screen.
