Some color displays have a wide dynamic range and are capable of producing very dark blacks with very low luminance. When using a spectrophotometer, such as the i1Pro 2, lower luminance can produce noise in dark color measurement that may have a subtle impact on profile quality.

i1profiler includes a special measurement mode for i1Pro 2 called High Precision Mode. When this mode is enabled, i1Profiler will extend the measurement period for darker colors, allowing the i1Pro 2 to collect more light and deliver a more precise measurement.

Please note: Using High Precision Mode will significantly increase your overall measurement time. In most cases, the difference in profile quality is negligible. However, if your display is capable of producing blacks with very low luminance, you may wish to enable this option.
