I have an Alienware Alpha v1 i7 with 16gb of ram. I can alter the resolution of windows to 4k and it outputs fine to my 4k monitor. 

Within Zwift it only gives me the option to bump the res up to 1440 and when I do this it outputs 1080p back to the monitor. 

The graphics card is a Nvidia GTX 800 series.

why can I not see the option or run Zwift in 2160p
