On my 2010 mac pro I have a 5870 video card with of its mini displayports (mDP's) driving a 27" ACD and a VGA monitor. I want a switch so that I can connect one of the mDP's to either the VGA or an HDTV. Basically an "A/B switch". Currently the only way I can do this is manually by unplugging the VGA and plugging in the HDTV and vice versa. Over time this can be a little hard on the connectors so a switch would be nice. But does such a switch exist? I've done a lot of google searches but turned up nothing. One search turned up the Atlona AT-MDP21 KVM which I thought maybe I could run in "reverse" but a quick call to Atlona tech support killed that idea. So I'm wondering if anyone has any ideas.
