I am looking at purchasing a SamsungĀ UN40KU6300, will I be able to get 4k @ 60hz with my early 2015 13″MBP as well as power a smaller 24 inch monitor?
Hello iop909,
Yes a MBP early 2015 supports 4K 60Hz output over its thunderbold2 output.
Setups with TV’s normally work best by making a custom resolution for 3840×2160 at 60 Hz with TIming Standard set to CVT_RB (Reduced Blanking). You will need a progrma like SwitchResX to do that timing standard setting.
