The frustrating thing about lowering brightness is that on a great number (probably the majority) of computer displays, lower brightness comes with lower contrast and color vibrance as a side effect of the pixels and backlight being separate layers in traditional LCDs. Because of this, for me the biggest benefit of upgrading to a phone with an OLED display was that it enabled me to adjust my phone's brightness without such dramatic loss of contrast and vibrance. Unfortunately I don't think OLED panels will ever become practical for desktop monitors… they're just now becoming somewhat available in laptops and even then sometimes come with issues similar to those seen in early OLED phone screens. We're probably going to have to wait for microLED tech to mature to get this benefit in full sized monitors.
