EDID Handling in UHBX-SW3
Version 1.0
Introduction
This document explains the EDID data available at each of the 3 input connectors of the UHBX-SW3.
Products Covered
This information is applicable to the following models: UHBX-SW3-WP and UHBX-SW3-S.
Setup Diagram for a Typical Installation
In order to explain where EDID comes from first let’s look at a typical setup.
The above diagram shows the three inputs on the UHBX-SW3 (one VGA and two HDMI), as well as
the Receiver (UHBX-R-PSE) to which the TV is connected.
This Receiver passes through the EDID data from the concerned TV upstream.
Unlike the direction of video flow going from the source to the TV, the EDID information travels in
the opposite direction. So in the above diagram the TV has its own EDID which gets to the Cat5
output of the UHBX-SW3-WP.
What the UHBX-SW3-WP does with that EDID data that comes from the TV is explained below.
