I carry my iPad everywhere, and now that I've got the new one with the high resolution display, I'd like to use it as a second monitor for my Macbook Pro. It would be great if I could occasionally use it as a second display for my various windows computers as well, but primarily the Mac.
I'm not terribly interested in using the touchscreen or moving the audio - in other words I don't need to control the computer with the iPad. I just want to extend the desktop with the retina display and give myself a ton more space with a tiny monitor.
What iPad secondary monitor apps support the high resolution retina display?
If there are several, preference would be given to the one that uses the least network bandwidth, if known. I won't be watching videos, but when I'm just showing a static image on the iPad (such as a document) I don't want it using 20% of my wireless network.
