So the calibration unit actively adjusts the monitor settings based on the ambient light in the room?
If so, then the issue I'm having right now is that I'm editing in an area that has a lot of window light...during the day its pretty bright in here. I have an LG ultrafine monitor that will torch up to 500nits, which is great when its bright, but there have been several occasions where I am editing when its a bit darker and when I look at the output later, the exposure is much darker than I was targeting.
I never ran monitors on high brightness. I keep shaded on my computer room and the BenQ came with addition shades to block light.
