I have been experiencing this on my 2k monitors as well (Also BENQ). I tried every "fix" under the sun, eventually it stops after enough voodoo (reboots, unplugs) and cursing.

One of the many random issues on the OS with the best UX in the world (lol). Like music sometimes stopping and sometimes switching to speakers when turning off Bluetooth headphones, mouse speed going bananas randomly requiring mouse off and on, terminal app (iterm2) reliably crashing when I dare to change any keybinding, and many other things that never happened in years of working on Linux.
