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),

Ok, after messing with this for several days I finally have an
/etc/X11/xorg.conf.d/10-monitor.conf file that allows allows use of the
recommended display set up.

However despite selecting 1680x1050 in the Display GUI menu nothing
changes until I do xrandr -s 1680x1050.
I can probably live with that by adding it to my routine set up
procedure it would be nice if I could make it come up that way after I
do "startx."
More help needed there, suggestions and criticism invited.
