Windows 10 Version 1903 causes image distortion and color display is not accurate

Recently, some user feedback that Windows 10 Version 1903 may cause distortion of the image or incorrect color display on some monitors. If you have such a problem, it is most likely caused by the Windows 10 v1903 update. In the feedback of many questions collected by WindowsLastest, Windows 10 Version 1903 and some GPUs are considered to be compatible, and the ICC configuration file may not work properly for the user. As a result, the image quality is poor, abnormal gradient patterns appear, and weak vertical lines at regular intervals.

This error also affects color accuracy when loading a color profile or calling the Calibration Loader task. In the Reddit community and the NVIDIA Forum, several Windows 10 users have confirmed color distortion issues. A Reddit community user wrote:

“I’ve been slowly driven insane by a bug for the last few months where my custom ICC profile and the default Windows profile will switch back and forth under certain reproducible conditions.”

In the support documentation, screen and display manufacturer Eizo has confirmed the bug, confirming that upgrading Windows 10 May 2019 (Version 1903) will affect the screen and display. After the latest feature update from Microsoft, calibration device manufacturer DisplayCal also confirmed color distortion.

According to DisplayCal, calibration loading may stop working in Windows 10 version 1903. This error affects the Windows internal calibration loader and the third-party calibration loader. Loaders that use the Windows SetDeviceGammaRamp API are also affected.
