Hi,
I've found this old but useful freeware utility that the lazy ones
should appreciate :-)
http://www.nirsoft.net/utils/dump_edid.html
So, my EDID dumps for two DELL monitors. They seem to use a funny EDID
Mixed serial.

Hello happy fusioninventory users.
While dealing with a bug about a specific kind of monitor, I
discovered an issue the way our code (happily borrowed from mandriva
parse-edid set of tools) interpret the value dedicated to monitor
serial number in EDID information.
Basically, the specification just says than the four bytes 12 to 15
are dedicated to this information, but doesn't says anything about
their interpretation. The code currently consider then as a single
decimal number, whereas the number printed on monitor label consider
them as a list of hexadecimal digits.
For instance, for a given raw bytes input "90 32 90 71", the value
could be interpreted either as:
- 1905275536 (single decimal value)
- 71903290 (the same hex values in reverse order)
Before taking a decision about this issue, I'd like a bit more
feedback about the real world situation. If you have some monitor with
printed serial number, can you check if they are plain decimal number,
or rather something like a fixed-length list of 8 hexadecimal digits ?
Even better, could you compare their value with raw EDID information
(1) ?
Thanks.
[1] useful way to extract EDID information:
- xrandr --prop under unix,
- HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\DISPLAY\*\EDID
value under windows
See http://en.wikipedia.org/wiki/EDID page for other suggestions
