Installation steps:
1. Insert the adapter into the KVM
2. Connect the 2 x DisplayPort cable to the KVM switch and monitor (output)
3. Connect the Displayport cable and USB cable to the KVM switch and your computer/laptop (DP cables are not included) (input)
DP IN1 A + DP IN1 B + USB IN1 = PC1
DP IN2 A + DPIN2 B + USB IN2 = PC2
DP IN3 A + DPIN3 B + USB IN3 = PC3
DP IN4 A + DPIN4 B + USB IN4 = PC4
4. Connect the mouse and keyboard to the KVM switch.
5. If necessary, you can connect a microphone and audio port.
Note:
1. Most of the reasons why only one video output works are due to the wrong port. Please make sure each computer with 2 DP cables and a USB cable is connected to the KVM.
2. If the KVM switch does not work, you can turn off the switch on the control panel and turn it on again after 2-3 seconds, then it will work normally again.
3. Before you buy this DP dual monitor KVM switch, please make sure your computer supports the direct connection of two DP monitors, otherwise the KVM switch will not work.
4. Note: DP cables are not included.
