I recently purchased a new PC laptop and I've been migrating over to it. I edit my photos on a dell unltrasharp 27" monitor connected with a usb-c/displayport cable. I've calibrated both the laptop and the monitor with my spyder x pro, and the profiles seem to be installed properly, and my screen saver image looks about identical on the 2 screens.
My problem is that when I open Lightroom on the external monitor, the colors are dull and undersaturated. These are previously processed images using my old machine on this same monitor. If I move LR to the laptop screen, the colors become lively again. I can see the shift happen as I move lightroom from screen to screen. The same Jpeg I use for a screensaver looks about the same on the laptop whether it's viewed in LR or googlepix or windows photos. And while the screensaver image on the external monitor looks like it should, the colors fade if viewed in LR or googlepix of windows photo. Very strange.
I've tried plugging the cable into the different alt/displayport usb-c ports. The one on the right connects directly to the Nvidia rtxa3000, while the one on the left connects through the Intel Iris iGPU. No difference.
I've tried disabling first the Iris iGpu (when it's plugged into the right port), and I've tried disabling the Nvidia GPU, the only difference is that when the machine is running strictly on the Nvidia a3000, google pix jpegs look like they should, but lightroom is still dull and washed out.
I don't think it's a color managed application issue, though. Why would the calibrated laptop screen show no difference between the same image viewed in LR and in googlepix. I've also viewed the images on my apple macbook air in safari, and they look like they do on the new laptop.
I even bought a new cable to rule that out, and the issue persists.
Any assistance would be greatly appreciated. Thank you,

Hi MIke
Quite a pain when there are color management issues.
- As a start, it would help to know the specific PC model as well as the specific Ultrasharp model to understand your issue.
- When comparing images only use images that have an embedded icc profile, otherwise color management software can display incorrectly
- When doing your comparisons, only use know color managed software such as LR, Photoshop, etc. Screensaver programs are not color manage and are not a good indicator that the color management is working properly.
- What is telling in your summary above is when you move the image from the external monitor to the laptop screen and seeing a big difference in the colors. To separate out the issues, please use an image that has an embedded color profile only and use a color managed application such as you were doing with LR. If the image does not have an embedded profile then change to an image that does have an embedded profile and see if the issue still persists. If the image you are using does have an embedded color profile and you still see a difference between you external monitor and laptop screen (supposedly color calibrated), than either the monitors are not calibrated or the system color management is not properly handling color management of two monitors properly. Most likely that would be incorrect settings in the color management or some limited capability for handling two monitors (less likely).
Just some suggestions
