This question already has an answer here:
I recently got a 4K 60Hz monitor for my 13" MacBook Pro Late 2013. It supports both HDMI and DisplayPort, but since the included cable is a full-sized DisplayPort cable, I'm currently using HDMI. Back when the rMBP Late 2013 came out, an article wrote about how it could support 4K@60Hz, but only on Windows because of a driver issue. I was wondering if that issue has since been fixed, and if it is possible for me to run my monitor at 60Hz.
I also tried to run it at 1440p@60Hz, using both System Preferences and cscreen, but neither of them worked. If it is impossible for me to use 4K@60Hz but it is with 1440p@60Hz, could you please let me know how? I am willing to purchase a MiniDP to DP cable if necessary.
Thanks in advance!
