ASPECT RATIOS EXPLAINED
Rev B June 2016
Aspect Ratios Explained
The appearance of a projected image on the screen depends on:
•
the DMD™ resolution, which is
4K
with a 4096 x 2160 resolution, corresponding to an aspect ratio of 256:135, or approximately 1.9:1.
•
the aspect ratio of the input signal, which is
1.9:1
for 4K and 2K images, or
1.78:1
for UHD or 1080p images.
2K and 1080p are automatically scaled by the projector to fill the height of the DMD™.
The 4K and 2K resolutions have a slightly wider aspect ratio. UHD and scaled 1080p do not fill the width of the DMD™, so they appear
centered, with pillarboxing at the sides, as shown in the illustration.
Notes
Pillarboxing on UHD and 1080p images
