I cannot see how to change the resolution of my recently purchased Acer B276HUL 27" AHVA WQHD 2K Monitor from its present meeting of 1920x1080 to match the resolution of the iMac which is 2560x1440.

 

The iMac and Acer monitor are connected via a CSL 2m (metres) Mini DisplayPort (miniDP) to DVI cable.

 

The iMac System Preferences/Displays shows only 1920x1080, 1600x900 and 1280x720 settings for the second display.

 

I shall be grateful for any help to change the Acer to match the iMac resolution.
