My Benq monitor also has built-in speakers that can't be adjusted.

A lot of displays do not support volume controls via DDC. If brightness control works only until 50% (if this is what you mean by the max brightness issue) then it is a good indication that DDC control generally does not work (it might be your dock) as the 0-50% range of the brightness slider is by default software dimming, not hardware backlight control.
