Transmit 4K60 HDMI signals up to 100 meters over CAT5e, CAT6 and CAT6A cable. Use the KVM Extenders to send high-resolution 4K at 60Hz (420 8-bit) video as well as signals for USB keyboards mice and other human interface devices (HID) and power and control signals. The extender includes a local unit that attaches to the CPU and a remote unit that connects the user's KVM console. But you can also plug in a monitor on the local side - which is great for monitoring and administration right at the computer. Requires only one power supply.
