Steam Deck iPad second screen, built for travel.

Travel setups: One tablet, one USB-C video capture card with Power Delivery. Play on a bigger panel in a hotel or on a tray table.
Wired 60 fps preview: A dedicated UVC pipe, not a compressed wireless stream.
Record to Photos: Phosphor Pro captures the Deck feed to the Photos library so you do not need a PC capture box for a highlight clip.
