EDID management: 3D when using EX50 50m extender set

If you’re looking to distribute a 3D source device using the EX50 50m extender set, then carry out the following steps.

1. Before you connect your 3D source device to the transmitter, locate the SimplEDID dial on the side of transmitter, which is labelled with the figure 3 below:

2. On the SimplEDID profile table in the EX50 manual, there are three choices of 3D EDID profiles (highlighted below). Pick the profile that suits the audio format that you wish to distribute.

3. Now use a small screw driver to turn the dial manually to the desired 3D EDID profile, which are lettered / numbered on the dial, as show below.

4. Finally, connect your 3D source device to the transmitter via HDMI cable. Connect the transmitter to the receiver using a single run of Cat cable and connect the receiver to the display using a HDMI cable.

If distributing to a local display via the HDMI loop out on the receiver, then also connect the receiver to the local display using a HDMI cable.

Power the source device on and the TV(s) should be showing the 3D video and outputting the chosen audio correctly.

IMPORTANT: With EX50s, changes EDID profiles are only recognised once the transmitter is powered off then on again.  

If you need to change the EDID profile of the EX50 extender set once the extender is up and running then you must disconnect / power off the transmitter. Next, manually change the EDID profile once again. Connect up the EX50s as step 4 recommends. You cannot change an EDID profile whilst the transmitter is connected / on.

 

Troubleshooting: Mixing 3D and 2D on a matrix or splitter

In order to route 3D content easily via a matrix switch or splitter, ALL connected displays need to be 3D compatible. Even, if just one of the displays is not 3D compatible, the 3D source player will NOT output the 3D content. The HDMI handshaking process will trigger the source player to drop it’s resolution output so that all displays can show content.

The problem is HDMI is designed such that the source ‘polls’ the EDID data (EDID is a display’s identity card stating what it’s capabilities are, a bit like a top trumps card) from all connected Sink devices (your 3D enabled display and non-3D enabled AVR) and outputs the lowest quality video signal all devices support (2D in your case).

To ensure 3D IS routed via the Matrix Switch or Splitter, the non-3D compatible display device must not be ‘active’. Sometimes turning the display into standby will be sufficient and sometimes full power off is required.

Essentially, the 3D source player must not be able to ‘see’ a 2D only display connected to the Matrix Switch or Splitter.

For best results when using 3D Blu-ray – HD Connectivity recommends… not actually connecting your 3D Blu-ray (BR) player to the Matrix. As Blu-ray 3D content is generally only viewed at a single ‘main’ TV location, in this instance it is better to have a direct connection between source and display, bypassing the Matrix completely. This will avoid any potential for ‘black screen’ situations at the other TV locations. It will also ensure that absolutely the best 3D format is selected for use on that display, not a potentially reduced quality 3D format that a lower 3D-capable display, connected to the matrix can influence the 3D BR to output. (Plus wearing those massive 3D glasses all around your house is really not cool and could result in you bumping into doorframes! – Ed)
