Sure there is -- you have a mechanism to tell the driver to re-probe
(whether that be BIOS for most laptop panels, or DDC), and return an
appropriate list of resolutions, and then use XRANDR to change them;
this is quite probably a candidate for an extension to RandR.
But that's non-trivial to achieve, and would be hell painful.
