I have a 12" Linux laptop with HDMI, DisplayPort and VGA ouputs. I can successfully export a display of a resolution up to 2048x1536 to any vanilla display or TV.
I also have a 27" Mid-2010 top of the line iMac with a Lynnfield quad-core i7, on which Linux is also installed.
I have seen that two Macs can, since OSX Lion, export display to each other.
Can I reproduce the same feat ? That is, I want to export display to my 27" Mac, is that possible ?
