No I think you are doing things properly, if Fedora cannot detect the
correct modes for the monitor (as shown by the output) then xrandr will
not help.  I would look in /var/log/Xorg.0.log for clues.  If you are
using KVM switches, that might also be a reason.

Here is an excerpt from my Xorg.0.log on my ThinkPad to give you an
idea:

intel(0): EDID for output LVDS1
intel(0): Manufacturer: LEN  Model: 4011  Serial#: 0
intel(0): Year: 2009  Week: 0
intel(0): EDID Version: 1.3

[...]

intel(0): Printing probed modes for output LVDS1

Hope this helps,
