Ultra HD 8K@60Hz 3 Monitor KVM Switch Complies with DP 1.4 protocol, supports a maximum resolution of 8K@60Hz, 4K@144Hz and is backwards compatible. Only if both your computer graphics card, monitor and cable support 8K@60Hz, you can get the 8K@60Hz effect. So if you want the maximum resolution, you need to check your devices first. 3 display modes Advanced display Mirrored display Spliced display 1) The extended mode can output 3 different screens and the mirrored mode can output 3 identical screens. Note: If your graphics card has a splicing screen function, you can use the splicing screen mode. 2) The requirement for this KVM to achieve a triple screen display is that any PC you connect to has the ability to support a triple screen display. This has nothing to do with KVM. Installation steps: 1. Plug the DC/12V adapter into the KVM; 2. Connect the 3 x DisplayPort cable to the KVM switch and monitor (output) 3. Connect the 3 x DisplayPort cable and USB cable to the KVM switch and your computer/laptop (DP cables are not included) (input) DP IN 1A + DP IN 1B + DP IN 1C + USB IN 1=PC1 DP IN 2A + DP IN 2B + DP IN 2C + USB IN 2=PC2 DP IN 3A + DP IN 3B + DP IN 3C + USB IN 3=PC3 DP IN 4A + DP IN 4B + DP IN 4C + USB IN 4=PC4 Please check whether DP IN 1A, DP IN 1B, DP IN 1C and USB IN 1 match, and whether DP IN 2A, DP IN 2B, DP IN 2C and USB IN 2 match. Mixed insertion is not supported. The same applies to PC3 and PC4. 4. Plug the mouse and keyboard into the KVM switch. 5. If necessary, you can connect a microphone and audio port. Note: 1.

If the USB3.0 input ports are not connected or incorrectly connected, the USB output device will not be recognized. 3. Note: DP cables are not included.
