@Dariuz, oh ok, I see, systemd has its own import/db and changes on top, you
forgot to mention that in your report/bug description. I found back to info and
it has been fixed in systemd in that commit
https://github.com/systemd/systemd/commit/c6d7a5e9 and indeed there has been
not systemd
seb128: I checked and sadly none of the releases (including disco)
contains the hwdb fix - looks like it hasn't been released yet upstream
- latest systemd release (239) has been published before the fix has
been comitted.

that's already present in Bionic.

I've updated hwdata in disco, but looking at the gnome-desktop code it
seems to query the info from udev/hwdb nowadays and not hwdata. Could
you test on >= bionic if the vendor is still buggy (Goldstar instead of
LG)? The fix does make sense for xenial though so I'm going to SRU there

It's still valid. hwdata fixed the "vendor name" part of the issue.
u-s-d needs to be patched to fix the "nonsense diagonal calculation"
part.

Title:
Incorrect information about display shown in unity-control-center
In case it helps, I've seen comments regarding some TVs encoding the
aspect ratio (16/9 or 16/10) as though it was the size:
https://github.com/linuxmint/slick-greeter/blob/master/files/usr/bin
/slick-greeter-check-hidpi#L24-L29
Not sure what is the actual source of this information, though.

After examining raw EDID data from 2 different LG TVs I can see that both of
them set bytes 21 and 22 of the EDID data in a wrong way.
They both state that the display size is 160x90 cm which in turn corresponds to
a approximately 72" diagonal.
So unity-settings-daemon does its job correctly
