Okay, so Dell finally solved the monitor UI usability problem by placing a joystick on the back of the device and I cannot tell you how happy I am! 🙏 The person deserves a medal.
I agree, adjusting displays is a big pain. A long time ago all those adjustments used to be done using analog controls (like potentiometers) so you just had a separate knob for each (brightness, contrast, color, tint) and it was very simple and easy.
Requiring users to press buttons a gazillion times just to adjust something is crazy.
I had one device that used an analog-type wheel with hard-stop positioning (as you turned the wheel it clicked) and each click would advance the menu items. That was a compromise, but I still think analog controls are best for analog-type adjustments.
@trinsec On every single monitor (as in display device), I've had very awkward buttons somewhere at the bottom, front or side of the housing that in some way related to navigating the menu (e.g. selecting inputs, changing contrast, ...).
E.g. my LG at home has a row of capacitive buttons (so they are very, very sensitive to proximity) *under* the device (so you don't see them) and are coded like: left, right, cancel, okay. Guess what happens ;-)
My last Dell at work hat similar mechanical switches but you had to always match their meaning to what was displayed.
