The DDC protocol (see 'ddcprobe') is able to convey the capabilities of the
monitor to the host device.

'xresprobe' is currently what's used.  It is installed by default for setup
and calls many of the utilities above---including starting an X server to
grep the output for useful data-points.

It might be best to look at extending that.  It's all written in shell and
the various components are in:

  /usr/share/xresprobe/
