Early 2013 Macbook Pro with 4K From what I'm reading online it sounds like 4K displays like Seiki displays will work correctly with a late 2013 MBP or later. I have an early 2013 MBP and am not finding much of any evidence that a 4K display will work with this model. Will a 4K display work at 3840x2160 with at least 30 Hz on a early 2013 MBP? Does anyone have this or a similar setup that could provide feedback or any issues that have? I'm interested in an external display with a high resolution and 4K seems like the best option.
Yes, it is possible to drive a 4k Display with an early 2013 and even 2012 Retina Macbook.
