Most monitors have a pixel order of (from left to right) red, then green, then blue, but some do it backwards and OS X doesn't seem to be able to handle it sometimes.Īlso, sometimes it goes black for a second or two, and sometimes it shows green lines and plays a strange sound.

While running Windows 10 it looks better but is still at 30 Hz.

The active part is needed because otherwise it will pipe the same 1.4 as the HDMI ports if you use a "dumb" cable/adapter. The HDMI ports on the MBP are 1.4 and not fast enough, but the Mini-DisplayPort ports are fast enough. You'll also need an active (Mini-)DisplayPort to HDMI 2.0 adapter. You'll have to disable System Integrity Protection (which normally prevents system files from being modified - mostly for security purposes) to add custom "supported" resolutions to the Mac, which involves a reboot once to turn SIP off and again to turn it back on, all the while being more vulnerable than normal to viruses, although probably not vulnerable enough to worry too much as long as you remember to turn it back on.

I'm using a Sony 43" 4k TV with HDMI 2.0 right now.įor some reason the MBP insists it can only run it at 30Hz, but with a piece of software such as SwitchResX you can manually add your resolution/refresh rate combination to the list of "supported" resolutions. If any reader has a logical explanation and/or solution for this, please post your answer.Ĭan I do with my early 2015 MacBook Pro Retina?

This result has persisted despite restarting my Mac but I do not know if this behavior is limited to my example. The refresh rate on the 4K screen is dropped to 30 Hz if it's one of only two active displays. To sum up, this means that my early 2015 rMBP 13" will only display 4K 60 Hz on the screen capable of doing so if either all 3 displays are active or the 4K display is the only active display. Scenario 3 = 2 desktops without builtin screen:ĭisplay 1 (old) is connected with 900x1440 60 Hz,ĭisplay 2 (4K) is connected with 3840x2160 60 Hz Scenario 2 = 2 desktops with builtin screen:ĭisplay 2 (4K) is connected with 3840x2160 only 30 Hz RMBP Early 2015 with macOS 10.12.6 and 16 GB RAM ĭisplay 1 (old): 900x1440 via mDP-DVI adaptor and DVI cable Display 2 (4K): 3840x2160 via mDP-DP cableĭisplay 2 (4K) is the only desktop displayed at 3840x2160 Hz

Also, MacOS does not let me choose the refresh rate for the 4K screen when it's connected through the Mini DisplayPort to DisplayPort cable - other than feeling the difference, I only see the refresh rate in the system profiler. However, there are anomalies on my side when it comes to the refresh rate depending on my screen setup. I have a similar device (Early 2015 rMBP with 16 GB running macOS Sierra 10.12.6) and can confirm that it will power an external 4K display at 60 Hz - it's supposed to power two external displays at 4K (3840x2160) in addition to the builtin display, in fact.
