just bought DisplayLink to start using on macOS Big Sur 11.0.1 using MacMini m1 16GB RAM with Dell 27" 4k monitor and DisplayLink does NOT support rotation - the apple system preferences shows the monitor as being rotated, but the imagery is very much still looking like landscape when screen is portrait making editing long word documents extremely painful.
