The analog input issue depends definitely on your monitor's way of dealing with that input. basically, it has to sample the analog input to fill the digital framebuffer and your lcd is designed to do both hfill and vfill it seems.
on my sunray 1 (and sunray 2 i later tested) in 1600x1200 it would display with black bars on each side on 24 inch lcd 1920x1200. after a while i switched to a pair of 1g. i was using dvi. i have not tried a 1920x1080 monitor but i would expect the same scenario to play out (black bars on each side).
