So I'm contemplating buying a 19" LCD monitor from the large computer company where I work. But, I decide to check the online reviews first. I see lots of people complaining that the display is too bright in a dim room and that the brightness control barely works and doesn't adjust the brightness sufficiently. So, I go and find a sample in the building to check out. Duh, we've followed the television convention of still calling the controls "Brightness" and "Contrast". So if somebody is looking at a mostly white screen and adjusts the "brightness" control, almost nothing happens. Ah, but the Contrast control adjusts the "brightness" and always has. I bet almost nobody except TV nuts like us even know this.
