Hi everyone Some monitors have problems in deep shadows zone: from max black to some level of grey no detail is seen on display. Please tell me algorithm, that help me to fight this problem. Try to manipulate screen brightness/contast with grey step chart on screen? Or try to increase black level during calibration (via video card LUT)? If yes, how to determine brightness of black point that I must to set? Too high black point will reduce my screen contrast and too low black level will not help me with this problem. I'm using ArgyllCMS with Eye One Display 2 Thanks for attention, and sorry for my English
