Read is not enough. If you have connected one /dev/fbx to two
monitors, you must find highest common denominator for them, and use
this one.

Err, i don't understand this ? Do you mean you are outputing to two
monitors at the same time ?

Yes. With matroxfb you can output same signal to all three outputs.
It is default if you have g450 or g550 with recent driver.

If that is so maybe you mean, speaking in graphic card terminology, and
not in fbdev one, that you are sharing one common framebuffer between
two outputs, right, possibly doing mirroring tricks or something such ?

Classic example is a SiS 6326 driving monitor and TV. You need to keep the
display to TV acceptable ranges.

You mean, driving both display with the same ramdac ?

See http://www.bglug.ca/matrox_tvout/g450.jpg. Two inputs, three outputs,
and almost any possible connection between them.
