I calibrated my monitor after doing everything I noticed in black level test on logam lcd test, the first two squares were crushed ( http://www.lagom.nl/lcd-test/black.php) I didn't want to mess with all the calibration, so out of curiosity I decreased the contrast from nvidia panel from 50% to 47% and now I can see both missed squares without any problems in the other departments, my monitor is an amva+ panel with static contrast ratio of 3000:1 so does decreasing the contrast by 3% cause any problems in terms of fidelity of color? or am i good to go....thanks so much
