EDID CLI tools - tiny-pilot/tinypilot GitHub Wiki
Displays share their capabilities with other devices with a message called an EDID. The EDID contains the display's manufacturer name, product name, and other metadata.
You can use some helpful CLI tools to dump and decode the current connected display's EDID on Linux-based systems. However, these tools don't allow you to edit the EDID. If you need to edit an EDID, you can use AW EDID Editor. You can install AW EDID Editor on Linux-based systems using Wine.
Install the packages
Install the read-edid
and edid-decode
packages using apt

sudo apt install read-edid edid-decode -y
Usage examples
Dumping the current display's EDID
Grab the EDID and hex dump it to stdout
:
sudo get-edid --quiet | hexdump -e '16/1 "%02x" "\n"'
Grab the EDID and dump it as a binary file:
sudo get-edid --quiet > current-edid.bin
Decoding an EDID
Grab the EDID and decode the information into human-readable text:
sudo get-edid --quiet | edid-decode
Decode an EDID from a binary file:
decode-edid < edid.bin
