How to Calibrate

  1. Black Level: Adjust your monitor's brightness until square 1 is barely visible against the black background.
  2. White Level: Adjust contrast until square 254 is barely visible against the white background.
  3. Gamma: Use your graphics card control panel or monitor OSD to adjust gamma to 2.2 (standard).
  4. Test in Dark Room: For best results, calibrate in a dimly lit room.
