So I've got both a 27" iMac and a Windows gaming laptop. What I'd like to do is connect my laptop to my iMac in order to gain more screen real estate for gaming. Here are the specifics: 27" iMac: 2011 model with DisplayPort. Laptop: HDMI and VGA. If I go MiniDP to HDMI adaptor -> HDMI cable -> HDMI in on laptop, will I be able to use the iMac as a display? I'm a little iffy about the possibility of doing this while the iMac is in OS X, but I also have it Boot Camped where I have much more faith that this will work. Thanks!
