I fail to understand why the Surface Pro has a Mini Display Port instead of just an HDMI. I have read many of other members theories but they seem just that. That being said does a thunderbolt cable work on the Surface Pro? I plugged mine into my Alienware from my Surface and couldn't get anything. Everything I see is Mini Display Port to VGA or HDMI which is completely confusing to me. Also does anyone know if or how I can use the Surface Pro as a digitizer drawing pad for my main rig, or even use it as a second screen? I'm just trying to figure to figure this strange device out.
