I have recently moved country with my retina MacBook Pro 15", and will be picking up a Wii U this December. I'm not here for too long so don't really want to commit to buying a TV if it can be avoided.
Is there any way I can use my MacBook Pro as a target display for the Wii U?
Unfortunately that's not good enough for gaming; the lag would be unbearable or settle for no HD. I researched this extensively when I got my MBPr and there isn't anything available right now (not even for the Thunderbolt Apple Cinema Display either).
