First for non-Mac Pro Apple computer
The Retina MacBook Pro is capable of displaying images on up to four screens at once, notes Other World Computing. The upgrade vendor has produced a photo to demonstrate. One person at the company comments that "Moving images and media didn't create any lag" during testing, and that they "were able to play video on all four displays simultaneously."
The OWC setup involved two iMacs used as Thunderbolt-connected monitors, and a third dedicated monitor hooked up via HDMI. In all the the test Pro is said to have pushed out about 15.6 megapixels in real time. Apple's own documentation quietly mentions support for a such a setup; this makes the MacBook Pro the first Apple computer to support four simultaneous displays outside of tower systems like the Mac Pro.
