Hi everyone! I just updated to windows 10 and I can't seem to change the screen brightness, it seems to be always at max, and when I start bringing it down(light is always at max anyway), the screen is turned off at a certain point and I have to turn it up again. Anyone knows how to fix this? Thanks
"The adaptive brightness feature taps into the ambient light sensors to automatically adjust your display to match surrounding lighting conditions. Thus, adaptive brightness is useful in conserving battery life since the display is a pretty power-hungry component."
This might happen due to a driver malfunction. In my case, Windows was using a driver from TeamViewer Foundation (checked on Driver Details) in each of my 2 screens.
To solve it, I had to Uninstall (checking the option to delete the driver) twice for each screen (uninstall, uninstall, rescan, uninstall, uninstall, rescan). After that, Windows was back using it's own driver and the brightness adjustment was back.
Sometimes, when Windows install a major update, the TeamViewer driver comes back and I have to do all this again.
