You would think monitor manufacturers would the brightness control go all the way to barely visible, but they don't. I have two monitors, an Asus and a Dell, both set to what they consider brightness level 0, and neither quite as dim as I'd like.

On most display devices, "contrast" controls the white level and "brightness" controls the black level. (These controls of course interact.)

For your use case, you might want to be adjusting contrast down.

You can get them to go lower at that point by decreasing the contrast. But yes, you highlighted what my problem with brighter displays is.
