I am using the Spyder4pro to calibrate my MacBook pro retina display and it asks what my display's gamut and backlight are.

Choices for gamut are: Unknown, Normal, and Wide. Choices for backlight are: Unknown, Fluorescent (CCFL), White LED, and RGD LED.

Which of these should I select to match my built in screen?

  • Well, seems like Unknown is what you have, given you do not know. The calibration is unlikely to be less accurate, just take longer to account for more possibilities. – Itai Dec 30 '15 at 22:13

Spyder's software is probably going to suck horribly, you should be using Dispcal GUI.

It's going to be sRGB (normal gamut) -- see post 5, here: http://www.notebookcheck.net/Review-Apple-MacBook-Pro-15-Retina-2-3-GHz-Mid-2012.78959.0.html

Backlight is LED, third post here: https://www.ifixit.com/Answers/View/190272/No+backlight+after+LCD+replacement

.. I don't know if it's RGB or white. I assume the latter, but I don't think dispcal will even ask between the two.
