Windows Monitor Calibration Issue

Calibrating your monitor is important because most monitors are not calibrated by the manufacturer, and do not display accurate color. See Calibrate Your Monitor.

But even after you've calibrated your monitor, it may not display accurate color, especially if you are running Microsoft Windows and have uninstalled the calibration software.

If you research this issue you're likely to be told that Windows doesn't load the calibration CLUT (Color Look-Up Table) properly, and advised to keep calibration software installed. But even then your monitor may not stay calibrated, shifting between calibrated and uncalibrated for no apparent reason. The truth is that monitor calibration can be made to work properly under Windows if you take the necessary steps:
  1. Stop Losing Display Calibration with Windows 7 details how to configure Windows to use a calibration color profile. But that may work for you at first, only to shift back again. Something may seem to be fighting with Windows. If so, check the article again, and see the note regarding Intel display drivers, which will lead you to:
  2. Intel’s Video Drivers Kill Display Calibration, which explains how Intel interferes with display calibration, and how to solve the problem by disabling the Intel Persistence module. If you use Sysinternals Autoruns to disable Persistence, your monitor should then stay calibrated even without calibration software installed!
