A 3104 48Gbps 2 Input HDMI Switcher
Overview
This switcher can switch any of 2 HDMI sources to 1 HDMI display. It sup-
ports video resolution up to 8K@60Hz 4:4:4, 48Gbps video bandwidth. It is
suitable for outdoor display, video conference, security monitoring, home
theater and other applications.
By using this HDMI 8K switcher, you are allowed to connect from HDMI IN1
and HDMI IN2 ports to two HDMI source devices via an individual HDMI
cable, then connect from HDMI OUT port to your external monitor (such
as HDMI projector, HDMI TV or HDMI ordinary display). You can switch
between two sources by pressing the switch button on the top panel of the
switcher. In order to make sure that your display shows normally, we sug-
gest you to plug the Micro USB cable in the package into your USB device
to power the switcher.
Please pay attention that this switcher is not a bi-directional switcher, you
can only use from two sources to one display (only 2 in 1 out, not 1 in 2 out).
It can work well with Xbox or PS5 to achieve 4K@120hz on your TVs or
HDMI enabled monitors.

Notes
1. While using the HDMI switcher, power supply via Micro USB cable is
not necessary. But in case some HDMI devices carrying insufcient power,
please connect Micro USB cable to a USB 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 icker.
The following HDMI cables are suggested.
8K60, 8K30, 4K120: Ultra HDMI2.1 cable, IN/OUT 2 meters.
4K60 4:4:4: HDMI2.0 cable, IN/OUT 3 meters.
