Need help with calibration.

[Julio Zabre]

Hi and hope you are having a nice day. I’m opening this topic to whoever can help me out. I recently purchased the Spyder5Elite and the results that I got where awful. thankfully I found DisplayCal and the difference I got is night and day, yet since this is such an advanced piece of software I’m unsure if I’m getting the most accurate result that I can. Can anyone tell me which setup/configuration I should use to calibrate? here is what I got:

1. Datacolor Spyder5 colorimeter.
2. iMac 27″ 5K late 2017.

These are my main doubts:

1. What Mode should I select for the instrument? I believe my iMac is a wide gamut and DCI-P3. is that something that I can select or which is the right option?
2. If I do the calibration at 120 cd/m2 is to dim for my eyes. If I raise it to something that is brighter does that affect the accuracy of the calibration?
3. When the tools pop up the interactive display adjustment I can’t do anything but adjusting the brightness since I have an iMac. Does that affect the process?
4. I have not found anywhere in the web a correction that suits with the iMac 5k and the Spyder5. Not sure how much this affects the process.
5. Does it matter what color profile is selected during the calibration? I mean if the iMac has the DisplayP3 profile when I start the calibration, does that matter? is it recommended that I start with a different profile?

Any help advice that you can send is welcome. Thanks in advance for your time.

Hi and welcome to the forum.

1. The Spyder5 does not have a matching measurement mode for the P3 iMac displays, but there is a correction ‘Apple iMac 27″ 2017 mid’ in the online corrections database which should be a reasonable match.
2. You can (and should) use whichever target brightness is suitable for your lighting situation. I’d recommend not setting a brightness target.
3. That’s fine. Aim for a brightness that is neither too dim nor too bright for your lighting. Ignore the bars.
4. See 1.
5. No.

Hope this helps!

I downloaded the correction you note above to calibrate ny new iMac withe my  Spyder5; however, when I try to load it DisplayCAL does not recognize it (greyed out).

Any ideas?

Did you click the correct button (“choose…” next to the corrections dropdown)?
