A lot of monitor firmwares always report the same size even when
there are many different models of the monitors with different sizes.
This can screw up gnome DPI computations and give you
funny sized fonts.
I bodged the EDID info for my samsung 46 inch TV
that reported its size as 9 inches and used the kernel
parameter to point to my new EDID:
drm_kms_helper.edid_firmware=edid/zootyrgb.bin
Now all modesetting video drivers always get the dadgum
DPI correct (of course the binary nvidia driver
doesn't do modesetting, but you can create an
xorg.conf.d file for it to explicitly set the DPI).
Thanks, Ed, Rick and Tom. Notwithstanding the reported problem,
everything seems to working fine.
EDID reports the following in my case:
