i have no time for testing this monitor with more details, also i'm not an expert.
i suggest you to go through the belows links if you really want to know more...
one thing i'm glad about that the OSD provides how many hours the backlight has been on, it is good for anyone who periodically conducts a calibration for monitor. I don't know if other models have this function at the same class, anyway it is a useful function for me~
