Simple Monitor Calibration Let your monitor warm-up for 30 minutes before calibration. The proper calibration is using a software . Make sure your monitor is in 24-bit or high-color mode. Use your normal room lighting but avoid reflections or glare from lights or windows. Locate the Contrast and Brightness controls for your monitor. These may be buttons right on the front of the monitor or you may have to pull up an on-screen menu to make these adjustments. 1) Turn the "contrast" control (usually marked with a circle divided vertically, one half filled in) up all the way. 2) Turn the "brightness" control (usually marked with a little sun-like image) all the way down--but finish reading these instructions first! (On a few monitors, turning the brightness down all the way may completely blacken the screen.) 3) Slowly turn the brightness up until you can just discern clearly each of the differently-shaded boxes in the black-to-white strip below; pay especial attention at the left (dark) end. When you can just discern, without straining, the leftmost box and the one just right of it, stop. Be sure to initially run the control past that point a bit, then run it down and up a few times; you want to get this one right. You may be tempted to set the control higher than what I have described; if you do, true black will be faintly gray and, worse, subtle differences in some colors will be hard or impossible to discern. 4) Try backing the "contrast" control off a little, keeping an eye on the image below. If the picture seems to improve with a little reduction of "contrast" from maximum, leave it set there. Note that you must see the whole range of colors 21 each line.Download my icc profile
