I have an early 2014 macbook air trying to connect to a Dell 27 inch QHD monitor (model S2718D)
the monitor has 2 usb SS ports, a full size hdmi, and a usb-c port.
I have a miniDp to hdmi cable that only puts out 1080p (I tried pressing option > resolution but only goes up to 1080p)
I tried a miniDp to usb-c. didnt even work at all
thinking about trying: usb 3.0 to hdmi, usb 3.0 to usb-c, usb 3.0 to usb SS, miniDp to usb SS
according to the dell website the usb SS ports are downstream ports so that might not even be an option.
the goal is to get 1440 (QHD) resolution.
