The Asus GT 610 uses an Nvidia graphics processor whereas the Gigabyte
SKT-1156 Q57M-S2H has an Intel GPU.  My guess is it's the Xorg graphics
driver for Intel that's the problem.  I would recommend going the Nvidia
route, I have two mythTV systems both with an Nvidia GPU one as a
separate graphics card the other on the m/b.  I've always had least
problems with Nvidia GPUs and Xorg.  I know there are issues with their
drivers not being opensource but at least they provide them.  Nvidia
also provide a set of gui tools for setting up their driver and saving
and using the EDID.  If you go this route make sure you've got or
install the Nvidia Xorg graphics driver (why not try the Asus GT 610
from the desk top first if it physically fits for height?)
