This could be caused by a defective monitor profile.
As a diagnostic too,l and possibly a temporary fix, try setting the monitor profile to sRGB.
If this fixes the issue, you should calibrate the monitor with a hardware calibrator.
This will create a new profile that accurately describes your monitor.
Press the Windows key+R, enter colorcpl, and hit Enter.
Add the sRGB profile, then set it as Default profile.
Thank you for your prompt reply, it has helped at this time.
The Color Management Window in Windows 7 was empty, although recently my EIZO Color EdgeCG 241W monitor with the X-Rite i1Display Pro was calibrated and Windows after the calibration saved the created profile.
Few days ago did not want to start up Adobe Photoshop CS6 because the Monitor profile was damaged. How is that possible? This so-called damaged profile is no longer recall.
How can I prevent a damaged Monitor Profile?
Thanks for your reply, greetings, Kati
I don't know what causes monitor profiles to be damaged, but sometimes a Windows update can replace the profile with a manufacturer's profile, and they are surprisingly often bad out of the box, so to speak.This happens with Windows 10, but I've never seen it reported with Windows 7.
I have Windows 7 myself, and nothing bad has ever happened with my monitor profile.
So i can't tell you how to avoid damaged profiles, but you should calibrate regularly, and if you have the slightest suspicion that something is wrong, calibrate as soon as possible. Using sRGB is only a temporary fix.
A bad profile can manifest itself in different ways in LR - no image in Develop, like you experienced, different colors in Library and Develop, a brownish yellow cast on the histogram in Develop, and different colors in Lightroom and Photoshop.
Photoshop will sometimes tell you that the profile is damaged, but as far as I know, Lightroom will never do that.
