Hello, is there a way to set/modify brightness and contrast levels of my DELL U2312HM via Mac OS as I do with my primary display (Apple Cinema Display 23" HD). I found a windows software (softMCCS) to that and I was wondering if there is a solution for Mac too. I'm actually using it with a DVI cable and a DVI to DP adapter (so it is connected using display's DVI port and video board's DP port). My video board is an ATI Radeon HD 5870. Will a different connection change something? HDMItoDP? DVItoDVI?
