Digital cinema aspect ratio masking
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 digital cinema masking is enabled, the source signal is masked to only show the
pixels within the chosen aspect ratio. The following table lists the active pixels that will be displayed for each
image container and aspect ratio.
