Crestron HD-TX-4KZ-201

The Crestron HD-TX-4KZ-201 is a DM Essentials transmitter (marketed by some resellers under the earlier "DM Lite" name) with two plain HDMI inputs and automatic switching between them — distinct from the HD-TX-4KZ-211-2G-B wall-plate transmitter, which instead pairs a single HDMI input with a USB-C DisplayPort input.

It extends 4K60 4:4:4 video with HDR10, HDR10+ and Dolby Vision over a DM 8-pin RJ-45 connection to a DM Essentials receiver or DMPS Essentials switcher, which is required for configuration and control.
