No exactly. See examples: "Smooth" (U2410 Standard mode with 255-255-255): http://img12.tar.hu/janos666/img/82927235.png "Immediate" (l220x with 255-255-255): http://img12.tar.hu/janos666/img/82927237.png ; "Crossing" (U2410 sRGB mode with 255-255-255): http://img12.tar.hu/janos666/img/82927236.png (Ignore the starting sections on these examples!) The Standard mode may worth to be optimized with OSD Gains because the lines don't cross each others. These curves will be nearly coherent after RGB Gain setup. The l220x is questionable. I didn't waste my time to test it. RGB Gain controls are useless in sRGB mode because the curves cross each others. So, these curves won't be coherent after you set the white point with the Gains. (But the maximum achievable contrast ratio will be lower.)
