Notes
1. While using the HDMI switcher, power supply via Micro USB cable is not necessary. But in case some of your HDMI devices have insufficient power, please connect a Micro USB cable to your USB devices for power supply.
2. If you need to use the switcher to output signals of 4K@120Hz or 8K@60Hz, please make sure that your HDMI cable, HDMI signal source and HDMI display all support the above resolution.
3. The length of the HDMI cables connected to both ends of the switcher should not be too long, otherwise it will easily cause the screen to flicker. The following HDMI cables are suggested:
8K60, 8K30, 4K120: Ultra HDMI 2.1 cable, IN/OUT 2 meters.
4K60 4:4:4: HDMI 2.0 cable, IN/OUT 3 meters.
4K60 4:2:0, 4K30, 1080P: HDMI cable, IN/OUT 5 meters.
