Haha no - retina = double pixel count in screenshots

Damnit, you got my hopes up that there was some modern version of the big-bertha or something.
Eizo makes a pretty awesome ~4k x 2k display but my budget is closer to $3,000 than $30,000.
I could have sworn the biggest retina display was 2880 x 1800 hence the question.
