running a 1440p monitor on MBP13“ early 2011

[WetTeddy]

Dear all,

I am struggling to run a 1440p monitor (BenQ BL2420PT) of my MBP13“ early 2011.

According to Apple my MB should be able to output a video signal up to 2560x1600. 

I managed to run the monitor just fine at 60Hz 1080p via HDMI using a MDP to HDMI adapter. However, that is not the resolution I am looking for.
Connecting the MBP via MDP to full sized DP cable (no adapter) won’t work at all. The monitor does not recognize a signal, no matter what resolution I set on the MB. The MB is recognizing that it is connected to a BenQ with the native resolution of 2560x1440p.
In the monitors menu I can choose between DP 1.1 & DP 1.2, but neither works at any resolution. The monitor always says „no signal“. 


Anyone who has a setup like mine working? 

Any suggestions what I can do? Should the HDMI be able to handle more than 1080p?

Thanks,

Frido

MBP is running 10.11.6

I can only suggest trying a different cable. Stick to a certified cable from a reputable manufacturer. Read this over:
