How to use

Connect up to four HDMI source devices to the switch's input ports and run an HDMI cable from the switch output to the display. If your display and external audio device support ARC, connect the audio device according to TV and receiver/soundbar instructions and enable ARC in the TV menu. Use the front-panel controls or the included remote (if supplied) to select the desired input; the device can also switch automatically to an active source depending on configuration. Ensure all connected devices are powered on and that HDMI cables meet the required bandwidth for 4K signals.

Usage recommendations

For reliable 4K performance, use high-quality HDMI cables rated for the bandwidth required by your source devices. If you rely on ARC for audio return, verify that ARC is enabled on the TV and that the external audio device supports the same ARC features. Place the switch where it has adequate ventilation and avoid tightly coiling HDMI cables to reduce signal degradation.
