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. Unfortunately, all the fonts and objects are unbearably blurry compared to my MacBook Pro. I have connected the two with thunderbolt. You'll also need an active (Mini-)DisplayPort to HDMI 2.0 adapter. Hi, I just purchased the LG 34UM95 external monitor for my MacBook Pro (Retina, 15-inch, Mid 2014) running on Yosemite (10.10.2). 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. The MacBook Pro 'Core i7' 2.8 15-Inch (Dual Graphics/Force Touch - Mid-2015 Retina Display) originally was only available as a 'configure-to-order' configuration of the MacBook Pro 'Core i7' 2.5 15-Inch (Dual Graphics/Force Touch - Mid-2015 Retina Display), but Apple later added it as a standard option, as well. 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. things like overheating, freezingmacbook pro 2015 bluetooth problems. 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.

For me, the sweet spot is to set the scale at 100, then open Universal Access settings. 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. I find the default setting of 2880x1800 at 200 scale to be too big. 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. ![]()
