The new 4K ultra HD format provides a resolution of 3840 x 2160 pixels. Combined with HDR (High Dynamic Range) technology, the viewer is provided a truly stunning and immersive viewing experience.

Currently, the 4K physical disc format is the only way to view true 4K originated content on today's 4K television monitors. The 4K UHD BD Disc format supports both Dolby Atmos and Dolby:X HD audio formations.

In essence, 4K UHD Blu-ray discs are like HD Blu-ray discs but with superior resolution, color, playback and dynamic range capacities as well as much larger storage capacity.

4K discs are available in three capacities, with a 50GB version at an 82Mbps read rate, a 66GB version at 108Mbps and a 100GB version at 128Mbps.

Masters for 4K UHD replication must be submitted in Cutting Master Format (BDCMF or Sony CMF) on removable USB 2.0 hard drives formatted for Windows or submitted as BDCMF or Sony CMF image on BD-R.

NOTE: subject to capacity/availability of this format, OMM Inc. may support UHD replication and mastering through OMM Inc. established offload channels.
