I've been searching around on the internet, and can't find an answer that makes me confident. I've seen examples of the rMBP driving 3 displays, plus the rMBP. Will 4 displays with daisy chained DisplayPort work? I apologize that I don't have the model rMBP. This is for a client of our A/V company, and I am doing some research to make sure this will work. Here's a promising link, which also references manufacturers artificially limiting the number of possible displays. Any experience is appreciated.
