As an report by The Verge, Apple published a support document today which lists three external displays that can use True Tone the Apple Thunderbolt Display, the LG UltraFine 5K Display, and the LG UltraFine 4K Display.
True Tone is a feature which adjusts your display’s white balance to match ambient lighting, it was introduced to macOS for the first time with Apple’s new Macbooks. But now it turns out that its coming to external monitors as well.
For those who are not familiar with it. True Tone aims to make displays easier on your eyes by subtly shifting the colors to match the light around you. For example, if you’re in a room with very warm light, your gadget’s displays will tend to look relatively blueish. True tone will make your display warmer to compensate. If you’re in a room with very cool light a rarer, but still possible situation True Tone will do the opposite.
In essence, it tries to make whites on your screen match the way a sheet of white paper would look in the same room. The shifting white point does have an effect on color accuracy; you wouldn’t want to do color critical work like photo editing or color correction with True Tone on. But it can make general computing – reading text in particular – much more pleasant.
Apple mentions that TrueTone works on these screens when connected to your MacBook Pro. Presumably, the technology works using sensors in the MacBook Proitself, which means that it might not work if you want to use an external monitor with your laptop lid closed.
We don’t know when it will start rolling to the market but one thing is sure that it will be a great thing to checkout.
