I received the display today and connected it to my MacBook Pro (13-inch, 2016, four Thunderbolt 3 ports) via the USBC port. Unfortunately, I cannot select the correct screen resolution 3440x1440. A maximum of 2560x1440 is possible. The display is distorted accordingly. When connected via HDMI cable, the resolution is correct. What do I have to do to set the correct resolution with a USBC connection?
