Lightroom Previews Colour Incorrect

[stephenb44252687]

So why does Lightroom Classic one day show the correct colours on previews, the next day not?

When this started, nothing updated, nothing was installed, one day it was working the next day not.

Everything has a brown cast. I've looked at the endless posts on this community, tried all the suggestions and nothing fixes the problem. I've tried the specific monitor profile, the sRGB profile, set them as default, loaded the latest graphics drivers, rebooted/restarted endlessly.

The only place to see the correct  colour is in the develop module full screen.

So what do you have to do to get this to work. Trying to sort through photos and can't see the correct colour in the library module is frustrating.

This sounds like a defective monitor profile.

Did you restart LrC after setting it to sRGB?

Please post a screenshot of the Windows Color management dialog after having set the profile to sRGB.

Also post a screenshot of the entire Lightroom window with an image open in Develop (not full screen mode), and make sure that the histogram is visible.

Do not attach the screenshots, use the Insert Photos button in the toolbar to insert them directly in your post.

LrC has been restarted and the computer rebooted numerous times.

If I go to Preferecnes and disable the Graphics Processor, the full screen picture in the Develop Module becomes the same colour as the filmstrip.

The only place to see the correct  colour is in the develop module full screen.

So are the colors in the main image in your screenshot (which is not full screen) wrong, or are they correct?

If I go to Preferecnes and disable the Graphics Processor, the full screen picture in the Develop Module becomes the same colour as the filmstrip.

Do you mean that disabling the GPU leads to wrong colors everywhere in Develop?

The colour in the large preview screen is correct, the preview filmstrip is incorrect.

Yes, If I disable the Graphics Adaptor the main large preview screen changes colour to the saem as the filmstrip previews. (which is incorrect)

I see no problems in your system info, except that the LogiOptions plugin in the past was known to cause very long startup times. I doubt that it's the culprit here, but it doesn't hurt to disable it to check. (File > Plugin manager)

Your issue is a very strange one, I have never seen anything like it.

Have you changed any settings in the Nvidia control panel? If so, try to reset them to default.

The only other thing I can suggest at this point is to try resetting the preferences.

I guess Lightroom just isn't meant to run on a PC. It's horribly slow, now this colour problem, and I haven't changed anythign to casue any of this to happen.

Shame that we have to pay to use it and get a slow buggy piece of software ported from Apple.

[Per Berntsen]

I gave you several suggestions in my previous post. Have you tried any of them?

LrC runs perfectly fine for most of us, also on Windows computers, which is what I have.

I'v been using it since version 2 (2008) without major issues.

Something particular to your computer is causing this.

[stephenb44252687]

Yes I have done all that you asked.

[D Fosse]

As Per says. This has nothing to do with platform. You have some specific problem on your machine that the rest of us don't have. We need to find out what. Adobe's user base is roughly 50/50 Windows/Mac, so they obviously don't "favor" one over the other.

Do you have HDR enabled?

BTW - I googled the Aorus FV43U, and it's a P3-type display. So sRGB IEC61966-2.1 is in any case the wrong monitor profile to use. Try Image P3 instead. Of course, the real solution is to use a calibrator to make a custom profile based on measuring your display.

[stephenb44252687]

HDR is not enabled.

There is a specific FV43U monitor profile which I have tried as well.

Funnily, Photoshop runs fine, Davinci Resolve runs just fine, Blender runs just fine, NX Studio works just fine...so go figure...

Is this a preview problem? You could try renaming/deleting the "XXX Previews.lrdata" file, forcing LR to rebuld the previews.
