I have a LG 37450 IPS and I'm using a Giada CUBE-N3-D2OB Intel Atom 330 CPU NVIDIA ION
connected with HDMI and it seems like the resolution is wrong.
Here's what I'm talking about. I also had this same problem when I connected my old PC system using DVI-HDMI.
I'm not sure what the problems is but I've been to AVS forums and it seems that none of them has the same problem as me. So I'm guessing it might be a driver problem.
