I've bought a cheap, old, second hand Targus docking station that supports the DisplayLink drivers.
- colors are a bit different on the monitor connected via DisplayLink compared with the first monitor connected natively via an ordinary cable. I compensated the difference to some extent by tweaking the hardware settings in the monitor.
- the Night Shift mode, reducing blue light, is not supported via DisplayLink (nor 3rd party tools like f.lux)
