Check that the HDMI wall plate and the connected display or downstream equipment support your source’s resolution and format, since some models support video up to 4K at 60 Hz with 4:2:0 chroma. For audio, confirm that the plate carries embedded HDMI audio or supports the separate audio input your setup needs, and that the receiving equipment can handle that signal.

Choose an HDMI wall plate with built-in switching when users need to connect and select between multiple sources, such as HDMI, USB-C, or VGA. Choose one with signal extension when the display or AV equipment is farther away and the system uses compatible HDBaseT equipment to carry the signal over a longer cable run.

Confirm whether the HDMI wall plate requires a single-gang or two-gang wall box, and check the specified box depth and available space before installation. For transmitter-style plates, plan a category cable run to a compatible receiver, then connect the source using the supported input, such as HDMI, USB-C, or VGA, and follow the model’s cabling and distance requirements.

HDMI wall plates with an HDBaseT transmitter send video and embedded audio from an HDMI source over category cable to a compatible receiver connected to the display. The receiver converts the signal back for display, and the supported cable type and transmission distance depend on the equipment and installation.
