Colors are messed up

[annconstantino]

Ever since upgrading my computer so I can run Lightroom's denoise without a long wait, the colors in Lightrrom have gotten weird. Way oversaturated greens, some other colors washed out. How can I fix this? Thanks in advance. This is only when I view photos in Lightroom. When I view them in photo viewer they look normal.

Either a GPU/driver bug, or a broken monitor profile (which you can sometimes get through Windows Update).

What GPU, what driver?

Does it go away if you disble the GPU entirely in Preferences?

Do you see this in both Develop and Library?

The photo viewer doesn't display the raw data, only the embedded jpeg preview put there by the camera.

Thanks for the reply! As usual, I am probably not smart enough to answer your questions, but here goes....Here is the hardware that came with the upgrade. I am a computer idiot, so I hope ths helps:                                                                       * AMD Ryzen 5 5600X 6-core, 12-Thread Unlocked
Desktop Processor
* Asus Motherboard supports new video card and up to
128GB of RAM
* 32GB DDR4 16x2 RAM
* Medium tower case with fans and cable management
* Nvidia 3050 8GB Video card
* New 600 watt power supply

At first I thought I had exposed the photos poorly, so I went ahead and edited as usual. Then when I played a slide show in Windows photo whatever I noticed everything looked dull (because I had compenstated by de-saturating the greens, etc.)  I could send a screenshot showing the two different saturations side by side if it would help. Yes, it is seen both in Library and Develop. The monitor is also new, but it displays everything else (internet images, etc.) normally. I don't know how to disable the GPU. Thanks again.

You disable (turn 'off' ) the GPU in the Lightroom-Classic's Preferences/Performance tab-

[Use Graphics Processor :] = Off

Also test your Monitor Profile as suggested in this link-

MONITOR sRGB PROFILE

"compenstated by de-saturating "  Editing in LrC only records changes in the Catalog- it does not alter the image file (including the camera jpeg preview) on the hard-drive at all. And so the comments from @D Fosse apply- "The photo viewer doesn't display the raw data, only the embedded jpeg preview put there by the camera."

Thanks for the replies. I am sorry I am so dense about this, but it just doesn't make sense that the only place on the whole computer that has these weird oversaturated colors is in Lightroom. Nothing changed when I disabled the GPU in Lightroom preferences.

I am attaching a screen shot of the two different looks. When I export without editing (I don't use Lightroom catalog, please don't judge) to the folder where I keep my pictures, the colors look normal. See attached screenshot showing the filmstrip from lightroom and the unedited exported image. If I edited the photo and got ris of the weird colors, the export would look dull. I hope I'm explaining this right. Thanks for your kindness.

If disabling the GPU doesn't help, you most likely have a defective monitor profile.

Different color managed applications (like LrC and Photos) can react differently to a bad profile, which seems to be the case here. LrC is particularly picky about the monitor profile, while other applications tend to be more forgiving.

Try setting the monitor profile to sRGB (use Adobe RGB if you have a wide gamut monitor).

With LrC and Photos closed, press the Windows key + R, type colorcpl in the box and press Enter.

In the Color management dialog that appears, add the sRGB profile, then set it as default.

If this fixes the issue, you should ideally calibrate your monitor with a hardware calibrator. This will also create and install a custom monitor profile that will be more accurate than sRGB.

Thanks. It turns out that the monitor has other issues, so I am swapping it out. If the new one produces the same problems, I will try what you suggest. Thanks very much.

This worked. Thanks so much. Just like magic. I so appreciate your input, and everyone else's.
