I`am using dual monitors Huawei Mateview GT 27'', VA, QHD, 165Hz, 1500R, HDR, Display on my working PC. They are connected to AMD Radeon RX5500XT video card with HDMI (one monitor) and Display port (second monitor).
The problem is that Gnome Night Light works only to one monitor (connected to DP). There is no matter whether you are using Wayland or Xorg session. The result is always the same. I have tested Redshift which works only with Xorg session.
