Generalized Timing Formula.  It's a VESA standard that allows mode setting
given just the horizontal and vertical resolutions, and any of the following:

vertical refresh,
horizontal frequency, or
dotclock.

Meaning, no need for mode tables, and it can support practically any combination
of xres, yres and refresh rates.

Ok.  I would presume that the model that does support digital input will also
have a different model id in its EDID block.
