I have the Macbook Pro 13" 2017 non-retina. I am using a CalDigit Thunderbolt mobile dock to connect to 2 Dell monitors using HDMI cord. The dock supports up to apx. 4000x3000 display. In display settings my only options are 1600x900, 1080p, 720p. The 1600x900 sucks and the 1080p is still a little fuzzy. Can the Macbook not support any higher resolutions?
