Dear All,
I have just bought a monitor, which is detected by Fedora 24 as a
Goldstar company Lda 22",
but the monitor is a LG of 27".
How can this be fixed?
I am not an expert. But this sounds like a faulty EDID, or path to
read the EDID. Fedora / linux reads the information about the monitor
directly from the monitor itself. I think this can be overridden by
putting a configuration file in /etc/X11/xorg.conf.d/ with the
information needed. A search should turn up samples. Is it possible
that you already have an override file there, for a 22" Goldstar
monitor? Or that the connection to the LG is flaky, so the EDID can't
be read properly?
I vaguely recall that it is possible to dump the EDID into a file, and
point to it in the kernel start line somehow. Could be a faulty
memory, though.
