If the current active device is turned off (not in standby mode), the switch automatically jumps to another active device. However, certain devices-such as the PS5, PS4/4 Pro, Amazon Fire TV, Apple TV, Xbox One/S/Series X, and Nintendo Switch-continue to emit a weak voltage even when powered off. This prevents the switch from detecting the device as "off," thereby hindering the auto-switching function | 【Compatible with Most Devices】ROOFULL 8K HDMI switch with the latest multi-signal processing technology is compatible with a wide range of HDMI source devices, including PS5/3/4/4 pro, Xbox series x/s, Xbox 360, Fire TV Stick, Blu-ray player, Nintendo Switch, Apple TV, DVD player, Roku, Chromecast, laptop, desktop PC, HDTV, and projector.
