CKL Dual Monitor HDMI KVM Switch 4 Port is designed to control 4 dual-output computers or laptops and other applicable devices, using one set of keyboard, mouse and 2 monitors for extended, duplicated or spliced display at the same time.

How to Get Dual Monitor Display: 
Make sure to connect both cable A and B from each computer to IN A & IN B port on the KVM Switch.

Reliable adapters are needed but not included for DVI, VGA, Display Port (DP) and USB C video outputs, please be aware of the adapters you might need for your set-up before order. 

Avoid using adapters on both computer and monitor side simultaneously for a same video flow.

How to Get Keyboard & Mouse Work:
Make sure the USB of Cable A is plugged into each computer, the other end with HDMI only goes to IN A port on KVM not IN B port.

Scenario 1:Standard wired or wireless 104-key keyboard and 3-button mouse:
Connect them to rear USB mouse and keyboard port respectively. Wireless adapter goes to USB keyboard port.

Scenario 2:Gaming, multimedia, mechanical, optical keyboard and mouse that are not well supported on rear USB ports:
Turn off the hotkey by pressing the Hotkey On/Off (do not hold on to it), the rear USB ports will turn into standard USB2.0 HUBs, so there will be 3 USB2.0 HUBs for connecting your special keyboard, mouse and other USB devices. Next plug in the wire remote switcher and use the convenient one-button wired remote selection instead.
