Package:

1 x 2 port HDMI KVM switch + 16 x HDMI cables + 4 x USB 3.0 cables + 1 x DC 5V 2A Power adapter + 1 x manual + 1 x wire remote push button switch

Tips:

1. If your devices without 4 HDMI interfaces, please purchase 8K adapters with chip. The quality of adapter will affect the function of the KVM switch;

2. If your devices with a docking station and you meet display issue, we suggest you use another docking station to have a try. The quality of docking station will affect the function of the KVM switch.

3. If you want to use 4 monitors, you should confirm that computer with 4 video output. If one of your computers with 2 video outputs, and you connect this computer into USB 3.0, A, C port of PC 1 IN, that monitors of OUT A and OUT C have display(another two monitors won’t display).

4. If you want to get 8K60Hz or 4K144Hz resolution, your devices(include computers, docking station, adapter) all should support that resolution. The KVM switch is like a bridge for transferring computers' signals to monitors, it can't change your devices' resolution. For example, all of your computers and the monitor all support 4K144Hz, but one of your computers needs to use an adapter, and this adapter only supports 4K60Hz, then this computer only supports 4K60Hz but not 4K144Hz.
