    This little potentiometer adjust display contrast, not its brightness / backlight intensity. I have an issue where two QCon devices look very different side by side - one has bright blue screen, another has much darker blue screen. Any advices? I can solder rome resistors or add potentiometer if needed, just direct me a bit, dont want to waste a life with figuring it out by myself.
