I knew nothing about any of this 2 weeks ago, and this was what I found trying to figure it out. Likewise, the 'Early 2013' MacBook Pro 'Core i7' 2.4 15' and 'Core i7' 2.7 15' are just 4 and 3 faster, respectively, than the 'Mid-2012' Retina Display MacBook Pro 'Core i7' 2.3 15' and 'Core i7' 2.6 15' that each replaced. I'm not sure how the other commenters are getting 4K 60Hz, but I think I've tried everything, and the results I've got are in line w/ the specs I could find. Also according to Dell, late 2013 rMBP has DP 1.2, which should be able to do 4K 60HzĪnd according to Wikipedia, DP 1.1a is limited to HBR, which is limited to 30 Hz at 4K / 3840 × 2160. I think it's because the early 2013 rMBP is limited to DP 1.1a, according to Dell. I am now using 2304 x 1296, HiDPI, at 30Hz. SwitchResX did help me get more resolution options than the standard display settings would. The cable I'm sticking with is the Startech mDP to DP, and the HDMI cable I tried was a 4K Belkin HDMI cable from the apple store. Does it mean the Early 2013 MacBook Pro won't be able to run macOS Bi. This LG monitor has DisplayPort 1.2 and HDMI 2. I read on macOS Big Sur Preview page that the upcoming release will support only the Late 2013 and later models of MacBook Pro. I could not get 60 Hz on any cable at 4K.

On my early 2013 15" rMBP and LG 27UD88-W 27" 4K UHD Monitor, and SwitchResX, I tried mDP to DP, HDMI to HDMI, all 4K compatible cables, and finally active mDP to HDMI 4k 60Hz cable.
