Hi everyone, I know the 2014 13 inch rMBP officially only supports 4K at 30 Hz. From everything I've read on these forums, that refresh rate is unbearable. However, I also know that there's a hack you can use with SwitchResX to get 4K screens running at 51-52 Hz using a 2014 13 inch rMBP. Given the hack with SwitchResX, do you think it's better to cobble together a 4K monitor and a 2014 rMBP or purchase a 2560 x 1440 monitor which it can run natively (no HiDPI) instead. I'm curious to hear people's experience with their set-ups; specifically how smooth and bug-free each option (particularly the 4K) is. Thanks!
