I'm currently on the road with my mac mini 2012. A friend I'm staying with has an iMac 2008 which I'm using as a terminal for my mini via screen sharing mode. However, running a mini headless ends up in poor graphics. They also have an old 15-inch DVI monitor that I can hook up to the mini to get the graphics chip going, but I'm still limited by the monitor's 1024 x 768 resolution. Is there any way to remedy that and have mac mini running full screen (1680x1050)?
