With a DCI-P3 display gamut, I am surprised and disappointed that even the high-end GPU in the 2016 MacBook Pro supports only 8-bit video.
With a wide gamut display, 10 bits is important to rendering subtle gradients seamlessly. Looks like we have to wait another generation for proper video support. Still, the alleged DCI P3 gamut is a big plus—that to be checked on soon.
MPG has not yet checked whether the 2016 MacBook Pro can deliver 10 bit color to external displays. It seemed unlikely given the half-hearted 8-bit video on the built-in screen, but Apple specs say it is so:
Simultaneously supports full native resolution on built-in display at millions of colors and:
One display with 5120-by-2880 resolution at 60Hz at over a billion colors
Up to two displays with 4096-by-2304 resolution at 60Hz at over a billion colors
Thunderbolt 3 digital video output
Native DisplayPort output over USB‑C
VGA, HDMI, and Thunderbolt 2 output supported using adapters (sold separately)
This is particularly disappointing having paid for the fastest GPU.
