This 3 Displayport+1 HDMI 4 monitor KVM switch is perfect for 4 computers to share 4 monitors and 4 USB 3.0 devices.
To make 4 monitors working, each computer will need 1 HDMI cable + 3 DP cables + 1 USB cable connection. Please buy good HDMI and DP cable yourself, if HDMI cable and DP cable is not good enough, the screen will flicker or unstable.
At least 1 or 2 USB 3.0 cable must be connected to the computer, otherwise USB devices such as mice and keyboards will not function properly
By using the wired control you can hide the kvm switch under the table and keep the desk tidy.
Please connect the 12V DC power adapter to provide sufficient power. Using a shorter 8K HDMI + DP cable can make the KVM switch more stable (It is recommended not to exceed 2 meters).
