Selecting the Correct Backlight Technology

FAQ Scenario

Products affected:

In response to the following question:

Q. I don’t know which ‘Technology Type’ to use for my display; can you advise which one best for my monitor?

Q. How do I profile to the full P3 gamut of my Apple XDR Mini LED Display?


The Solution:

When calibrating an LCD using ccStudio or ccProfiler, the software will give the option to optimise your measurement for different types of LCD backlight technologies. Both applications offer various backlights, including; CCFL (Cold Cathode Fluorescent), Wide gamut CCFL, White LED, RGB LED, OLED, Plasma and GB LED. To ensure the most accurate profile results, please make sure to set this option correctly for each of your displays.

It is always best to consult your monitor’s documentation or go to the manufacturer’s website for more information about the backlight technology used on your display. However, we have provided some additional assistance below for your convenience.


For general use desktop monitors not made by Apple visit:


Windows laptops – Generally use White LED unless otherwise indicated on the manufacturer’s website.


Apple display technology types:

– Mini LED – Current M1 and M2 series Macbook Pro systems and the Apple Pro Display use a Mini LED XDR Liquid Retina Display. On these systems a full P3 gamut is only achievable using the Calibrite Pro HL and Plus HL devices. For other devices and to limit display gamut to sRGB, select ‘PFS Phosphor’.

– White LED – Apple displays manufactured after 2009, including the new 27″ Apple Studio Display (see exceptions below)

– PFS Phosphor – Intel based Macbook Pro 15″ and 16″ manufactured in and after 2016 and Macbook Pro 13″ manufactured in and after 2020.

– GB-LED – iMac 4K 21.5″, 4.5K 24″, 5K 27″ Retina displays in and after late 2015.


Please note: spectrophotometer-based products (i.e., Calibrite ColorChecker Studio or X-Rite i1Studio) do not require a technology type.
