I presume "EDIT WRITE PC" does EDID EEPROM [re]write on PC/VGA input.
Now, the question remains, what data Tv is using as source for EDID WRITE. Apparently threre are some EDID "templates" embeeded in exeDSP:
Four variants for HDMI inputs (LCD/PDP, HDMI 1.3/1.2), and two variants for VGA input (LCD/PDP).
Also there are *.ddc files on the flash partition (/mtd_exe/EDID/); I've checked them with moninfo, and they don't look quite right (too old, and there are too few video modes listed; "Plug and Play ID" is SAM0418). Interestingly, AC3 HDMI audio is in fact enabled in GRU-ALNH*.ddc files..
