Hello there. I bought this model and there is something awkward happening. Whenever I see a page full of white (like this one), the screen has a certain bright. However, if I switch to another tab on my browser, something darker such as a picture or alike, the brightness drops a little. Is this normal? Does it has something to do with any setup? I know some has the power saving and light adapting functionality, but since I haven't found them on Display configurations, I'm assuming it is not related to it. It is a Win11 model, i7, Nvidia MX350, 8GB RAM and 256 SSD.
