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.
