Is it possible to create or extract the Extended Display Identification Data (EDID) for/from a monitor. I have some issues with my monitor with the VGA and HDMI cables and I would like to test if by adding the EDID to the Nvidia Settings it could help in solve this issues.

With the VGA cable I get a black out error and with the HDMI I get some EDID errors (bad EDID). So how can I create the EDID or extract it from the monitor by detecting its capabilities.

Got it. Was wrongly searching in the apt search box for ESID instead of EDID. Found the read-edid app which comes with 2 programs, get-edid which is the one I need to extract the data from the Monitor and then parse-edid which reads the binary output from get-edid (In the same pipeline) and parses it in a human readable format. After this I can include it in the Nvidia Settings and test out the outcome but at least I can extract the EDID from the Monitor.

The how to use it is also here: http://manpages.ubuntu.com/manpages/oneiric/man1/get-edid.1.html

but basically is what I just did:

get-edid > filename then parse-edid < filename or just do get-edid | parse-edid

Also the nvidia-settings includes a "Adquire EDID" button that saves into binary or text format.

I will leave this here although this question might not come out a lot, it will help anybody that is looking for something related to extracting the EDID.

    parse-edid had problems reading the dump that nvidia-settings creates. edid-decode worked though.
