Fantastic. Can you post one or two of those photos here in the thread? Also, can you test something for me? With one of the photos open in Photoshop, go to Edit>Assign profile, and assign the monitor profile to the image. Does it make it closer to the print, or further away? Or no change? Also, please confirm that your PS Color Settings are on "North America General Purpose 2". Anything else is catastrophic.

Excellent. Now we're getting somewhere. And can you confirm that this screen matched these prints when it used to be connected to the old computer?

I have to go and pick up the kids from school now, and then take them to sport. I likely won't be back online for a few hours. When I check back in, I look forward to hearing how your calibrated screen (Photoshop, nothing else) compares to the prints. Please keep it really simple: "My screen is _________________________ [colder/warmer] than my prints" That's all I need to know.

In a properly-working system, Adobe RGB and sRGB images (and any other colour space, for that matter) will display correctly and print as displayed (apart from gamut issues of course).

You have been using the terms "RGB" and "Adobe RGB" and even "Adobe sRGB" interchangeably, so I feel justified in my efforts to clarification. Please understand that changing your images' colour space DOES NOT affect calibration. There is a problem here, but that is not it. That's ok, we just need to know how it calibrates with this new system. And yes, sorry I wasn't clear - for troubleshooting purposes, it must be the only monitor connected.

And is it the ONLY monitor connected to your computer? You've disconnected the other one? No. ALL photos are RGB. https://www.damiensymonds.net/2010/11/colour-modes-vs-colour-spaces.html

I'm trying to follow this, and I'm confused. Have you, or have you not, reconnected your old screen to your new computer right now?

EVERY photo should be sRGB. There is absolutely no ambiguity about this. Adobe RGB plays no role in anybody's workflow, ever.

Good. So ... back to my question. When you calibrate the new computer with the old screen, how's the Photoshop-to-print match?

I would REALLY rather not rely on recent prints. Do you have some older prints (and their corresponding files) that you know used to match the screen just fine on your old computer?

Oh! And? How was the Photoshop-to-print comparison when you calibrated the old monitor?

That would be great. From this new computer?

Do you still have your old screen, by any chance?

You mentioned it's a new computer. Is it also a new screen?

If you suspect there's some in-system switching going on, use the "DisplayProfile" app to override it. https://www.damiensymonds.net/art_vista.html

No. Bridge shows the non-colour-managed image first, in the few seconds it takes to load the colour-managed version. What about ACR? Does it match Photoshop?

Trust me, it's VERY normal. People post dozens and dozens of screenshots for me every day in the raw class, and they're ALWAYS different from their photos. That's why I have to always make sure people post both the screenshot (so I can see their edit settings) and the actual photo (so I can see the colour).

Then the calibration hasn't been successful. Were you following my calibration instructions here? https://www.damiensymonds.net/cal_S5P_pc.html

This is perfectly normal. There is always some difference between non-colour-managed programs and colour-managed ones. The difference varies on different computers, but there is always some degree of difference. The only thing that matters is this: Does Photoshop match your pro lab prints?

What do you mean? You're still in them for months yet. Read them again whenever you like, as often as you like.

Oh gee, that's only four megapixels. Did you see the resolution guidelines at the bottom of this article?

Roughly what are the pixel dimensions of the files?

Ok, so your screen matches your prints now?

To be honest, I'm not sad about this. It will force you to clean up your computer and have much better habits with your files.

It's not about the PPI, it's about megapixels. Exactly as I said in that article.
