This is something on tvs and even PC monitors/speakers that’s left me a little confused. Sliders/incremental input are okay for basic settings adjustments, but if you know exactly what you want your settings at…Why isn’t there a direct number input option on more devices?
E.g. brightness: slider/increment or input number within [range].
Volume: slider/increment or input number within [range].
I was helping adjust a somewhat newer tv awhile back and it brought this back to mind.
If they give the number then most people try to stick with increments of five so they’ve adopted a “stop when it looks good” ux methodology.
It’s also cheaper because you don’t have to normalize and internationalize the numbers.
