HDR and Display Port problem

[Xenobius]

I connected Air M1 to LG 32UK550 monitor using Display Port cable (via Akitio Dock Pro).
The colours are washed out, HDR is enabled by default and there is no "High Dynamic Range" checkbox available.
I tried DP to HDMI adapter but it doesn't work.
Does anyone have any idea how to turn off HDR?

Fixed. I bought a BENQ EW3270U. Now I can switch HDR off.
Do not buy LG 32UK550 crap.
