USB-C and HDMI inputs.

A USB-C port ensures compatibility with MacBooks as well as PCs exclusively with USB-C for video output. With an optional power supply, the device can be charged over USB-C.

Supports 4K/60 with 1080p downscaling.

The OME-ST31A supports 4K/60 4:2:0 over the HDBaseT output, and full 4K/60 4:4:4 over the local HDMI output. 4K to 1080p downscaling is also available through the HDMI output - ideal for a secondary HD display as a confidence monitor.

Flexible powering.

The OME-ST31A comes out of the box for remote powering by an HDBaseT receiver or switcher. For standalone operation (local HDMI output only) or USB-C device charging, just add the optional power supply.
