Hi, I couldn't find a thread that about this anywhere. I don't know if it is just me because I have 2 friends who have the same model as me and they could rotate their monitor with a push of a button. For me, none of the buttons on my monitor works except for the one to adjust sound and the brightness. I'm pretty sure I installed all the drivers, but maybe I missed one. If someone call tell me how to get the monitor buttons working it would be greatly appreciated. Thanks.
