Strange monitor behaviour when calibrating it with the colorimeter
I'm trying to correctly calibrate my wide gamut
Acer Nitro XV273K
using an X-Rite i1 display pro colorimeter and i1 profiler software.
Something strange happen on this monitor that I never experienced before on other monitors.
I can easily achieve 6500K moving the Red or Blu gain but moving the Green gain seems to not influence the measured color temperature even if I can see the temperature changing with my naked eyes.
This is bad because I have one gain control less to achieve the temperature I want. It's like calibrating the monitor using red and blu only.
Why I have this problem?
