This utility is maintained here:

https://git.linuxtv.org/edid-decode.git/

To build this do:

git clone git://linuxtv.org/edid-decode.git
cd edid-decode
make
make install

Patches and bug reports can be sent to the linux-media@vger.kernel.org
mailinglist (see https://www.linuxtv.org/lists.php). Please make sure
that 'edid-decode' appears in the subject line and don't forget to
add a 'Signed-off-by' line when submitting patches!

If you don't know what that is, then see:

New sample EDIDs are welcome. Please note that these must be real
EDIDs read from real hardware, so no artificially constructed EDIDs.

The naming of EDIDs in the data directory is:

<vendor>-<model>-<port>[-tileX]

<port> is one of dp, hdmi, vga, dvi
When a tile is also specified, then dp should include the DP connector
number, e.g. dp1-tile0, dp2-tile1.

All lower case.

If the EDID was modified by other devices in the chain (e.g. AV Receivers),
then name the EDID as:

<TV vendor>-<TV model>-<TV port>-<AV vendor>-<AV model>-<AV port>

The test directory contains some special input files to verify the
edid-decode parser and hand-crafted EDIDs to test rarely seen
EDID features.

You can find a very large collection of EDIDs here:
https://github.com/linuxhw/EDID

This collection has been used to test edid-decode.
