Using the default profile and then a calibrated profile (not with a colorimeter, just with the built-in wizard) the ACD 23" is extremely bright. I currently have the brightness nearly all the way down. Is it supposed to be like this? I came from a Samsung TN panel which I used to use on 'internet mode' which was like a compromise between the too-dark text mode and the too-bright gaming mode. I don't know if my eyes just need to get adjusted or what, but it comes absurdly bright.
