The 8k HDMI and display port 4 PC KVM switch allows you to directly control 4 computers and 3 monitors using a single mouse and keyboard.
If you need multiple PC to share 4 USB 3.0 ports, you need to connect a USB cable to each PC (4 USB 3.0 cables are included with this product).
USB 3.0 is faster than USB 2.0
Note: If you need to use 8K resolution, it is recommended that you use a 4K@120Hz/8K high refresh rate cable within 3ft or a high quality docking station/adapter.
