@potatosubwoofer @MotoWiZ MY PROBLEM: The lower monitor will change contrast/brightness (using some total luminosity of pixels metric). So what happens is if i am on a page with a light background the lower monitor will increase its brightness (hurts the eyes when using in dim conditions), on the other hand if the page has a lot of dark pixels the lower monitor will instead decrease brightness (make it hard to read), Its very counter-intuitive in the way it works.
CAN YOU CHECK A DIFFERENT SETTING: Windows Settings>System>Display>Brightness>
There is a drop down if you click on brightness with a toggle for " Help improve battery by optimizing the content shown and brightness"
I only have this for the upper monitor, the lower monitor doesn't contain this settings. Can you check if you have it for both or only one.
