Hello Some people have encountered the same problem: The screen brightness in Windows 8.1 (bootcamped) is way too low. I've seen the solution to turn off adaptive brightness but it doesn't help. The only thing that weirdly helps, at least temporary, is to close the lid and reopen it (with settings that makes sure that nothing happens except the screen turns off), because then it brightens up to maximum, but once I run a fullscreen application or something else that makes the screen "flick" it dims to a less bright state. Anyone have another solution than just adaptive brightness? Btw, I use a late 2013 rMBP. Thanks in advance!
