Hello,

i am using the i1 Display Pro to calibrate and i have noticed that when i compare my old profile to the new one, the new one has a grey/greenish tinge.. does anyone have a guide to properly calibrate an iMac 5k with the i1 Display Pro?

Thank you

That looks like a good and comprehensive guide.

I'd just like to add that if this is one of the new DCI-P3 panels (Apple's variety of wide gamut), it's possible that it uses "GBr LED" backlighting, not "White LED", and the software should be set accordingly. This will affect the measured white point.

Most traditional wide gamut panels use GBr LED.

Generally, the calibration targets should be set to match the paper/final output (not the other way round). The numbers aren't important, D65 or otherwise. Let the numbers fall wherever they want. Just get that monitor white=paper white match.

Temperature is just half the story. That's just the yellow/blue axis. There's also a green/magenta axis to consider, and if this can be adjusted do so.

Hello, GB-LED is indeed selected (cant see GBr LED) and i still have the weird look. Could it be the lighting in the room that affects the profile too and how it is made? i have changed lighting setup.. my old profile from my old light setup displays true whites, but the new profile i made with the new lighting setup shows a grey/green tinge.

trshaner do you mean instead of GB-LED try selecting RGB-LED?

when i calibrate the brightness.. i set it for 120 and my display either does 113 or 142.. should i be selecting 120 instead of 142? doesnt seem bright enough lol

how do i get the white=paper match?

theres still a greyish/greeny tinge in my opinion.. if i switch to the standard iMac.icc inbuilt the whites are much whiter than when i switch back to my profile and a greeny/grey tinge flows across the screen.

the lamp is to the side (see attached pic). so i should edit in complete darkness?

now i have adjusted my screen brightness down it seems pics are blown out on other peoples computers.. do i need to edit photos and drop the exposure now?

The lamp location appears to be the primary light source and looks fine. With this ambient lighting a 120cd/m2 Luminance setting shouldn't cause you to adjust images so they appear excessively bright on other's monitors. Of course if they have the Brightness cranked to maximum then that might be the case, which also means other photographic images will also appear too bright. Please post one of the exported to JPEG images that appear too bright to a files sharing site and post the share link here. We can then provide more advise. You can also simply use insert image here in your reply.
