Matthew: these might *appear* the same "My resolution is wrong", but actual solution and problem are different for each case, particularly each make of card.
For example:
(a) The graphics card might not be detected and defaulting to 'vesa' (this requires PCI IDs adding to 'discover1-data').
(b) DDC failing on the monitor and getting the wrong capabilities.
(c) The Panelsize being wrong.
(d) The BIOS modes to program the ideal resolution not being available.
and there are going to be others. The useful stuff we need is:
/var/log/Xorg.0.log (X server log, which will show what driver is being used)
$ lspci -vn (PCI-IDs to show what the card *actually is*).
$ xresprobe ${DRIVER} (to find out if the DDC/FP size is correct).
