They are empty as far as I can see.
I switched to the nvidia driver to see what is displayed for the same files.
They are however not to be found. Nvidia must have adifferent way of accessing the
monitor information.

Depends I guess on the interaction between the driver and monitor and the
get-edid command. could be some context that are not properly setup for
the command to succed. Don't know the relationship between monitor information
and the kernel and the driver.
Is it something the driver has todo and provide to the kernel?
