Apple had introduced True Tone Display is MacBook Pros and iPad Pros. This technology measures the light in a room to strike the proper color balance and intensity on-screen.
Now, Apple published a support document today that details which displays will work with True Tone. They include: Apple’s Thunderbolt Display, which uses the Apple Thunderbolt 3 to Thunderbolt 2 adapter, LG’s UltraFine 5K, and LG’s UltraFine 4K.
Not only the display, but MacBook Pro’s touchbar also has True Tone. This external display support would mean that outside companies could slowly start to support True Tone. But knowing Apple, it’ll likely be highly selective about which displays can access the technology.
