Hi this is my first post. I got my sp4 pro around the middle of December and it has been working really well for me overall. The one thing that continues to bug me is the screen will change its brightness even though I have disabled the auto brightness in the settings. where it shows up the most is if I run acdsee with a dark background interface after a few seconds the screen will dim, if I then open up a file explorer folder over top of the interface the screen will brighten back up until I bring acdsee back to the front then it dims again. Is there anyway to disable the constant dimming of the screen with dark backgrounds that are full screen.
