The Ultra HD Story

The Consumer Electronics Show in Las Vegas this month was the showplace for the new Ultra HD 4K format for home entertainment. Ultra HD is based on the Rec 2020 standard, which provides for 4K resolution and a higher color gamut than found in home entertainment today. The new color gamut utilizes a full 10-bits, vs the 8-bits of color found in standard Blu-ray, and can carry the DCI P3 color space, a first for home entertainment. It can also deliver colors that go beyond P3. The new Ultra HD Premium logo indicates that the display will also support HDR peak brightness levels of either 540 nits or 1000 nits.
