I searched the forums and did not see anything on this topic. What are options for screen brightness? I know that some screens people use the back up cams type come with buttons that turn the brightness different levels. But for others that don't have a physical button. What option do we have? Is there any options in retropie? Any Scripts?

I haven't been able to find a way to change composite brightness. Unless the board comes with buttons.

Maybe someone else has. But I've really never seen it posted.
