Connection overview. Check the requirements below for the exact ports, cable type and supported operating mode.
Made for high refresh
Pass 1080P at 240/165/144Hz or 1440p at 144Hz for smooth gaming, trading and CAD — with no added latency.
Four USB 2.0 ports
Two of the four receiver ports supply 1A for power-hungrier peripherals such as lit keyboards or headsets.
Tidy and simple
One-way PoC runs the pair from one 12V adapter, and a Phoenix audio port extracts sound for speakers or an amplifier.
Make sure it fits your setup.

Does not work through an Ethernet switch; for network extension use 4KIP100-KVM.
One-to-one
One transmitter pairs with one receiver.
Splitters and switches
Can be used with an AV Access HDMI splitter or switch at the source.
