If you're looking for a KVM device, you already know what you're looking for. The Arkidyn KVM 4K HDMI Switch for 2 PCs/Devices works as advertised. Note that a 4k connection depends heavily on an HDMI cable being able to transmit 4k (not all, but the latest cables are). I've been using it for over a month and no problems. The desktop controller switch is handy enough as it has already been noted that there is no hotkey switch on this computer (due to 4k compatibility).
