XV273K hdr issue? my graphic / display settings it says hdr is off

Cfcboy

I'm having a weird problem with this monitor and not sure if its linked to my 1080ti.. hope someone can help.

When I set the monitor to its hdr setting (via the osd or the Acer widget) it pop very nicely and assume it to be a nice hdr. When I go into my graphic / display settings it says hdr is off (odd as screen looks amazing). So I turn on the hdr via windows and it looks awful, totally washed out and like the brightness has gone through the roof.

Do I already have hdr by setting it in the monitors osd? So by turning it via windows is having some kind of nasty double negative impact?
Same with the ps4 pro, looks nice but when I turn on hdr within settings its horrible to look at..

Any ideas as at a bit of a loss
TIA

I have this issue as well. I believe the monitor has a dynamic tone mapping feature that is always on and cannot be turned off sadly.
