New Retina MacBook Pros can drive 4K displays at 60Hz – when running Windows, Mac OS needs new drivers

Tests by French site Mac4Ever.com found that current model Retina MacBook Pro machines can use their Thunderbolt 2 connections to drive the Sharp PN-K321 4K display at 60Hz when running Windows 8.1 with the latest NVidia drivers, rather than the 30Hz possible with OS X. This suggests that OS X will be able to do the same when Apple updates the rMBP video/Thunderbolt 2 drivers.

While 30Hz is good enough for movies, our own Seth Weintraub found on his bargain Seiki that it gives a poor experience when scrolling webpages, and is of course completely unusable for games. 60Hz, in contrast, gives a smooth experience when using a computer. The mystery had been why the latest Retina MacBook Pros, with Thunderbolt 2 support, were limited to 30Hz when the specs should have made them capable of double this – and the video drivers appear to be the answer …

It’s possible, of course, but I strongly suspect not. As I argued in October, the launch of the Mac Pro would have been the obvious point at which to announce an Apple 4K display – and current MacBook Pros can’t drive 4K displays at decent frame-rates, so I can’t see Apple launching a display that would leave the bulk of Mac owners disappointed.

The far more likely explanation is that Apple plans to sell the Sharp displays alongside the Mac Pro once it launches – as I suggested it might in that same opinion piece in October. The displays were inadvertently made live on the store before the Pro was launched, and have been removed until the Pro is available …  Read more
