Working with 2K and 4K Digital Cinema Image Formats
The Z27x has direct support for the 2048×1080 and 4096×2160 image formats (containers) as
specified in the Digital Cinema Initiatives (DCI) - Digital Cinema System Specification. The following
table lists the supported formats.
DCI Level Horizontal Pixels Vertical Pixels Frame Rate
1 4096 2160 24.00
2 2048 1080 48.00
3 2048 1080 24.00
TBD* 2048 1080 60.00
* At the time of this document’s release, the 60.00 fps 2K format has not yet been formally codified by the DCI. Support for it
has been included in the Z27x in anticipation of future use and codification.
In addition, the display supports aspect ratio masking for the two standard aspect ratios, 1.85:1 and
2.39:1, within the DCI image container. When DCI aspect ratio masking is selected the source video
is masked to only show the pixels within the specified aspect ratio. The following table lists the active
pixels that will be displayed for each image container and aspect ratio.
DCI Container Size Aspect Ratio Horizontal Active Pixels Vertical Active Pixels
