How to Get Dual Monitor Display

1. Each computer needs 2 video connections using the included cable A and B.
2. IN A ports are for HDMI Out A display, IN B ports are for HDMI Out B display.
3. Use reliable adapters for computers for non-HDMI graphic outputs like VGA, DVI, DisplayPort or USB C), simple conversion cable may not work. VGA adapter needs to be powered.
4. Try not to use adapters on both computer and monitor for a same video chain. For instance, if you used an adapter for connecting IN B port, and another adapter on HDMI Out B, it may cause display issue. 

How to Get Keyboard, Mouse and USB Peripherals Work

1. Make sure cable A connections are correct. The USB must be connected to a USB 2.0 port on each computer; the other end with only HDMI must be connected to IN A ports instead of IN B ports.
2. Some keyboard and mouse with special feature may not work well on the 2 USB ports at back panel, if so, please turn off the hotkey then these 2 USB ports will change to standard USB 2.0 port like the front USB, and use the wired remoter to switch between computers.
