I am planning to buy a new monitor, QHD resolution (1440p) and 60Hz, for a desktop computer. Ideally, it should also be possible to use the same display with a couple of laptops: A late 2016 XPS 13 (9360) and a late 2016 MacBook pro, both of which have Thunderbolt 3 ports. I am ok with connecting and disconnecting a cable or two when changing the display from desktop to laptop and back, if needed.
I have found Thunderbolt 3 docking stations that solve the connectivity issue for the laptops, but these are expensive (over 200 euros). I have also found Thunderbolt 3 and USB-C to HDMI adapters, but these seem to be unable to drive a QHD display at 60Hz. I have not found any Thunderbolt 3 or USB-C to Displayport adapters -- do they exist?
What are my options for connecting the laptops without degrading the resolution or refresh rate for the monitor? Keep in mind that I have not chosen a monitor yet, so if specific connectors on the monitor are helpful, that may be possible to achieve.
EDIT: Corrected XPS 13 version.
