magenta overcast in lightroom 6 preview window

[nikan64]

Hi,

After I reinstalled Lightroom 6 on my computer, all pictures in a preview window have magenta overcast. If I export any of the photos from the library to jpeg then this overcast disappears.

What exactly do you mean by "preview window"? Library? Develop?

Do you get this cast in both Library and Develop?

Please post a screenshot showing the problem.

Right off it sounds very much like a broken display profile. Your photo viewer is probably not color managed and so doesn't use the display profile at all.

But yes, a screenshot would make things much clearer.

I include two screenshots of lightroom and  1 screenshot of a jpeg  file in window viewer exported with no developing whatsoever

Yes, definitely a defective monitor profile - the magenta cast in the gray areas of the histogram confirms it.

The bad profile was probably installed with a Windows update.

Since the Photo viewer doesn't use the monitor profile, it's unaffected.

As a (temporary) fix, set the monitor profile to sRGB (Adobe RGB if you have a wide gamut monitor).

You should then ideally calibrate the monitor with a hardware calibrator, which will create a profile that accurately describes your monitor.

Press the Windows key+R, type colorcpl in the box, and hit Enter.

Add the sRGB profile, then set it as Default profile. See screenshot (from Windows 7) below.
