This happens because your Windows operating system does not provide a valid ICC profile for your laptop's screen.
Do the following to overcome this problem:
- From the main menu, select 'Edit > Color Management Setup'.
- On the ColorManagementSetup tool, click the System Settings section.
- For New Monitor Profile, select the 'sRGB IEC61966-2.1' standard profile.
- Click the Apply Global button, or press F6, to execute the tool.
- Exit PixInsight.
- Run PixInsight. The Application will inform you that the monitor profile has been changed.
This will let you work in a color-managed environment with normality. The sRGB profile will characterize well your laptop's screen for most practical purposes.
