My only assumption on this would be that when using the usb to hdmi connector it does not support the resolution applied to the game. Have you tried and going into the game settings and turning the resolution down or up? I know with my tv I run a HP dv7 laptop with an HDMI connector to my tv. If I turn down the rez from 1600 x 900 to lets say 800x600 than it will take the screen down and turn black. I would test that out and see if changing that will help at all. Other wise i would invest in a vga to hdmi or dvi to hdmi if that is an option because you are not going to want that lag when your gamming, it will piss you off trust me. Good Luck!!!!
