sethismyfriend,
I was very excited about Galileo, until I found this stumbling block of 'no easy way to connect a display'.
For such a large company, I would of liked a full range recommended hardware coming from the developers; but it seems like just a Wifi card is listed as 'known to work'. I know this is very early in Galileo's development, but this doesn't look good.
I am now looking at Udoo Quad, as this offers LVDS and HDMI, Sata, etc... as well as all the Arduino shield compatibility.
Obviously, I am very disappointed not to be able to use Galileo; but I will have to wait and see what development boards Intel releases next, after they have learnt from the Galileo success or failure.
Good luck with your application !
