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: https://elinux.org/Developer_Certificate_Of_Origin 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: --[-tileX] 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: ----- The test directory contains some special input files to verify the edid-decode parser and hand-crafted EDIDs to test rarely seen EDID features. I host a simple website where you can paste an EDID and get the full edid-decode output here: https://hverkuil.home.xs4all.nl/edid-decode/edid-decode.html This is updated regularly with the latest edid-decode. It uses emscripten and the html file is maintained in the emscripten directory of edid-decode. To build edid-decode.js/wasm run 'make edid-decode.js'. This assumes that emscripten is installed, of course. You can use the konqueror browser to run it locally: konqueror emscripten/edid-decode.html For other browsers you need to serve the files using a local webserver. See also https://emscripten.org/docs/getting_started/Tutorial.html You can find a very large collection of EDIDs here: https://github.com/linuxhw/EDID This collection has been used to test edid-decode.
