Problems with Image From Mini-display Port to Display Port Connector

[Lekron]

Hello,

 

I just got a new asus monitor (ASUS ROG Swift PG279QZ 27" WQHD 1440P IPS 165Hz) and I am trying to connect it via a thunderbolt (mini-display port) to a regular display port on my monitor to utilize the full refresh rate (HDMI only supports 60hz).

 

When I connect the DP cable to the monitor it responds by flickering on and off, but then it says that DP signal is not detected and turns off. When I use HDMI there are no problems with the display.

 

I have the MacBook Pro (Retina, 15-inch, Mid 2015), Processor 2.5 GHz Intel Core i7, Memory 16 GB 1600 MHz DDR3, Graphics Intel Iris Pro 1536 MB.

 

Thank you in advance for any help,

 

Ryan
