CROP INPUT

The Crop Input menu is where the image’s frame is set. If there’s anything outside of the image that you want to remove, this is the best place to do it, i.e. before the image is scaled, preventing unnecessary artifacts.

Input Aspect Ratio – Auto Detect, 16:9, 4:3

The default is Auto Detect. In this mode, a 4:3 input frame is assumed if the input is standard definition (480 or 576 lines), and a 16:9 input frame is assumed if the input is high definition (720p and higher). If a forced setting is needed, select the one that displays the picture correctly – most often, this means selecting 16:9 when the source is standard-definition letterboxed. The most common aspect ratios are:

1.33:1

(4:3)

 

1.78:1

(16:9)

 

2.4:1

SDTV, classic movies

 

HDTV, widescreen movies

 

‘Scope’ movies, anamorphic projection

movies also 1.37:1

 

movies also 1.66:1, 1.85:1

 

also 2.20:1, 2.35:1, 2.55:1 and beyond

 

 

 

 

 

 

 

Custom

If the above settings aren’t suitable, select Custom and adjust Horizontal Size, Vertical Size, Horizontal Position, and Vertical Position. If using an anamorphic projection lens, set Vertical Size to 810 (even if output resolution in menu 1 isn’t 1920x1080 – the relationship is maintained to make setup easy).

Since position can be adjusted after size is adjusted, this can also be the right choice for off-center sources but in this case be sure to adjust size proportionally – you can use a geometry test pattern for a visual adjustment, or calculate the numbers by maintaining the 16:9 ratio between Horizontal Size (default 1920) and Vertical size (default 1080). If the input is standard-definition and letterboxed, use 64:27 to calculate the correct setting for a 16:9 screen. Horizontal and Vertical position defaults are 960 and 540, respectively.

Edges

This selection is independent of the preceding ones. When ‘On’ is selected, the edges of the input are trimmed. Use if you see any non-picture ‘garbage’ outside the picture, or for removing the small amount of letterboxing that results from displaying movies with a 1.85:1 aspect ratio on a 16:9 (or 1.78:1) screen when the display is not overscanning. Number of pixels removed is adjustable from 0 to 20.

Y/C Delay and Horizontal Offset

Adjust if image is not centered, or if YCbCr source needs Y/C delay adjustment. See also Sync in menu 1.
