How to use

Connect up to three HDMI source devices to the HDMI inputs and link the HDMI output to your display.

If several sources are active simultaneously, the unit follows its input detection logic to choose the appropriate source.

Usage recommendations

For reliable operation at UHD 4K60, use high-quality HDMI cables rated for 18 Gbps or higher and ensure source devices and display support 4K@60Hz. Place the switch within easy reach of connected devices and avoid coiling cables tightly to reduce signal interference.
