I have a MII 12000 and had a similar problem. I had to install the graphics drivers from via and I was able to select what freq I wanted in windows under advanced. Then I just set it to 75hz and it displays ok on my xenarc. The only problem is 75hz seems to be a bit fuzzier than 60hz and there is some strange very faint lines in light colors. I'm also wonder what others have done with their xenarc and these embedded graphics cards?
