Crop to DCI 2.39:1 Aspect Ratio This option crops 111 pixels from the top and bottom edges of the frame (for 2048-wide sources, 222 pixels from the top and bottom edges for 4096-wide sources). The resultant image is then displayed as specified using the Aspect Ratio Display options described in the previous section. Show Cropped Region When this option is enabled, rather than cropping and resizing the image to the selected aspect ratio, the image is not resized, but the region outside the desired aspect ratio is instead overlaid with a partially-transparent black mask. This option is useful, for example to check the top line in a 2.39:1 aspect ratio and see what information may be available, if the headroom needs to be adjusted via reframing. Set Cropped Region Opacity This option is available when Show Cropped Region is active and allows you to specify the amount of opacity applied to the cropped region. Adjust as needed to achieve the desired balance between the active and cropped regions of the frame. Displaying 4K Source Video Though it only has a native resolution of 2560 × 1440, the Z27x can receive and display a 4096 × 2160 or 3840 × 2160 input signal. Multiple scaling and display options are provided. To provide the highest quality display of 4K source video on the Z27x the scaling algorithm has been specifically tuned to provide a naturalistic scaling without any sharpness or edge enhancement. When a 4096 × 2160 or 3840 × 2160 signal is input into the monitor, the following scaling options are available via the 4K Sources section of the Digital Cinema Options page. If DCI aspect ratio cropping has been selecting, these options are applied after the image is cropped. Obey Aspect Ratio Display Option This default option will display the image according to the selected "Fill to" Aspect Ratio Display option. Refer to Using the Z27x Aspect Ratio Management Options on page 32 for information on these options. Scale and Show Center Extraction If selected, the center 16×9 region of the frame will be displayed with the areas outside of this center region cropped, similar to the Fill to Screen Height option discussed previously. The amount of the image shown in the center extraction is dependent on whether the entire container or an aspect ratio is displayed. Scale and Show Left Side of Frame If selected, the left-most 16×9 region of the frame will be displayed with the areas outside of this left side region cropped, similar to the Fill to Screen Height option discussed previously. The amount of the image shown in the left extraction is dependent on whether the entire container or an aspect ratio is displayed. Scale and Show Right Side of Frame If selected, the right-most 16×9 region of the frame will be displayed with the areas outside of this right side region cropped, similar to the Fill to Screen Height option discussed previously. The amount of the image shown in the right extraction is dependent on whether the entire container or an aspect ratio is displayed. Working with 2K and 4K Digital Cinema Image Formats 37

Crop to DCI 2.39:1 Aspect Ratio
This option crops 111 pixels from the top and bottom edges of the frame (for 2048-wide sources, 222
pixels from the top and bottom edges for 4096-wide sources). The resultant image is then displayed
as specified using the Aspect Ratio Display options described in the previous section.
Show Cropped Region
When this option is enabled, rather than cropping and resizing the image to the selected aspect ratio,
the image is not resized, but the region outside the desired aspect ratio is instead overlaid with a
partially-transparent black mask. This option is useful, for example to check the top line in a 2.39:1
aspect ratio and see what information may be available, if the headroom needs to be adjusted via
reframing.
Set Cropped Region Opacity
This option is available when Show Cropped Region is active and allows you to specify the amount of
opacity applied to the cropped region. Adjust as needed to achieve the desired balance between the
active and cropped regions of the frame.
Displaying 4K Source Video
Though it only has a native resolution of 2560 × 1440, the Z27x can receive and display a 4096 ×
2160 or 3840 × 2160 input signal. Multiple scaling and display options are provided. To provide the

Scale and Show Center Extraction
If selected, the center 16×9 region of the frame will be displayed with the areas outside of this center
region cropped, similar to the Fill to Screen Height option discussed previously. The amount of the
image shown in the center extraction is dependent on whether the entire container or an aspect ratio
is displayed.
Scale and Show Left Side of Frame
If selected, the left-most 16×9 region of the frame will be displayed with the areas outside of this left
side region cropped, similar to the Fill to Screen Height option discussed previously. The amount of
the image shown in the left extraction is dependent on whether the entire container or an aspect ratio
is displayed.
Scale and Show Right Side of Frame
If selected, the right-most 16×9 region of the frame will be displayed with the areas outside of this
right side region cropped, similar to the Fill to Screen Height option discussed previously. The amount
of the image shown in the right extraction is dependent on whether the entire container or an aspect
