Here's my situation in a nutshell. I've got a 2011 13" MBP and an XBox and a PS3. My parents don't want me having a gaming console in my room, but they're okay with the laptop. Since I have both consoles, I plan on keeping one in my room, but I only have one monitor (I play consoles on my 24" monitor). I'd leave the monitor where it is, and hook up my PS3 to my HDMI->mini display port and use my MBP as the monitor. I know this sounds crazy, and its an output only port, but I think there's an easy enough workaround. Unfortunately, I'm 14 and don't have the programming skills. Since Thunderbolt is hooked up directly to the core of the system, and doesn't have to run through an operating system and drivers to function, I think it could be used as a display input port. Using a HDMI -> mDP adapter, I could use the thunderbolt port as a HDMI input for my PS3. Since this would be extremely difficult to incorporate into a Mac App (I think...), it would make more sense to write a Linux build specifically for 720p thunderbolt input. I know Linux is used in TV's, so I see no reason why it wouldn't agree with HDCP. What I'm hoping for is for somebody superior to me to come up with a dead simple Linux build dedicated to video input. Sound isn't necessary, a GUI isn't necessary, even a command line isn't necessary. Set the only resolution to 1280x720 (720p), and have the display input send the picture to the MacBook's monitor. Googling "use macbook as monitor" brings on a boatload of "not possible" answers, and I just came up with this idea. I'm really hoping it would work, because it would be pretty awesome. If you have anything to say about this, positive, negative, and whatever else, post a reply or email me at email@example.com. Thanks.
