Thanks to the dual Thunderbolt ports and new HDMI connector in the Retina display equipped MacBook Pro, for the first time ever, a MacBook can power three external displays. Other World Computing today posted this image of a new MacBook Pro powering three high res displays, all at native resolution. This is quite an impressive feat, especially for a mobile video card.
The MacBook Pro pictured is connected to two iMacs running at 2560×1440 over Thunderbolt, with an additional LG monitor connected over HDMI running at 1920×1200. Not only can the MacBook Pro now push nearly 15 million pixels- more than ever before, but the new MacBook Air has also received an update that allows it to power two external displays, also a first.
Before now, the only Macs capable of driving more than two external displays were the iMac and Mac Pro, thanks to the Mac Pro’s expandability, and the iMac’s dual Thunderbolt ports.
OWC reports that the MacBook Pro was able to play video simultaneously on all four displays without any lag. Very impressive.
