Yes, I have this option. I am attaching a screenshot with this.
Unfortunately, I can’t check the sidecar, because my iPad Pro 10.5 about is still at iOS 10.3.4
Also, you can observe strange display frequency values (74.88 instead of 75 and 59.88 instead of 60Hz). This becomes returns to 75 and 60 when changing to 1080p (You can also see this in the screenshot).
I noticed the same behavior.
For the monitor connected via HDMI, the refresh rate is 60HZ on all resolutions.
For the monitor connected via DP, 60HZ is the default for 2048*1080, 1080p, 1080i, 720p.
59.88HZ is the default for 2560*1440, 2048*1152, and 1600*900.
But I am not sure whether this is an issue, because sometimes the refresh rate cannot be an integer due to some reasons that I am not sure of. There are some discussions on the internet.
