So the EDID is being read.
This readout can mean two things: either your monitor is reporting only
these resolutions as supported (and X chooses the highest one
available, 1024x768), or the radeon driver is probing only for these
resolutions (probably as a consequence of a config file).
So we need two more pieces of information: (1) the exact make and model
of your monitor, and possibly a link to its instruction manual or
technical specifications or similar (google is your friend),

and (2)
the contents of /etc/X11/xorg.conf.d/ directory (the files should be
small, copy-paste them directly into the e-mail).

If your monitor is too old or has a broken EDID information, we'll
probably set up manual modelines for your desired resolution in the
config files. But first we should see the current configuration.
The monitor is old, perhaps 4 years, but little used, an artifact of the
last Windows computer in the house, replaced by an iPad, etc. Still too
good to toss overboard ...
Thanks,
