EDID Handshake

What is an EDID Handshake and When Do You Need One?

EDID (Extended Display Identification Data) is the information a TV or display sends to a connected source device to describe what resolutions, colour formats, and audio formats it supports. The source device reads this and decides what signal to output.

When new equipment is introduced to a Neo Matrix setup, or when changes are made to the system, the matrix may not have correctly read the EDID from all connected displays. This can result in:

A blank picture on one or more outputs
Incorrect resolution being displayed
Audio not passing through correctly
A source outputting a resolution the TV cannot handle

Performing an EDID Handshake forces the matrix to re-read the EDID from all connected displays in the correct sequence, which often resolves these issues.

How to Perform an EDID Handshake

The order of this sequence matters. Follow each step carefully and do not rush between steps.

Turn off the matrix and all source devices (Blu-ray players, set-top boxes, games consoles, media players, etc.).

Turn on all TVs and displays. Ensure they are not in standby — they must be fully powered on and displaying their input selection screen.

Wait 45 seconds to allow all displays to fully initialise.

Power on the matrix. Wait until you see 3 solid green lights on the front panel, indicating the matrix has fully initialised.

Wait a further 45 seconds.

Turn on all source devices.

Test each output to check whether the picture has been restored.

If the EDID Handshake Does Not Resolve the Issue

If you are still experiencing picture problems after performing the handshake, the issue may be a deeper EDID compatibility problem rather than a timing issue. See: General EDID issues and how to identify them
