4. Introduction
The HDMI 3 x HDMI + 1 USB-C 4K switcher 4K@60Hz 4:4:4 lets you connect a display or
projector with three HDMI enabled video sources and one USB-C enabled video sources. The
switch features four independent (3 x HDMI + 1 x USB-C) inputs that each support 4K resolution
and 7.1 surround sound audio. You’ll be amazed at how this video switch maintains Ultra HD
picture quality. 4K is supported by the latest A/V devices and delivers four times the resolution
of 1080P. Plus, because the switch is backwards compatible with high-definition 1080P, you can
rest assured any video source will look great in your digital signage application. Enjoy hassle-
free operation with three different switching modes.
1. Manual Port Switching: Enables you to manually select your HDMI source with easy-to-
use panel button.
2. Remote Control Switching: Enables you to control the switch at a distance.
3. Automatic Port Switching: Enables your most recently activated video source to be
display automatically.
It also features automatic and manual switching mode change function and IR receiver on/off
function via long pressing the switch button for 3 and 6 second to meet customer’s needs. It
uses a USB-A and USB-C port for charging which needs power supply below 5W (5V 1A) max
each using the charging port not at the same time.
5. Features
