Hello to Everyone!

Cant find information about working macbook pro retina 2015 and monitor with resolution 2560x1440 (Dell P2416D)
What refresh rate will be?


This is what apple says:

Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 3840 by 2160 pixels on up to two external displays, both at millions of colors

Thunderbolt digital video output
Native Mini DisplayPort output

HDMI video output
Support for 1080p resolution at up to 60Hz
Support for 3840-by-2160 resolution at 30Hz
Support for 4096-by-2160 resolution at 24Hz

Don't know about using the HDMI port, but you can definitely get 60hz+ with Display Port.

60Hz using HDMI.

Simply put: 3840x2160x30 > 2560x1440x60
