• Aspect Ratio - Paste Settings: To apply the Output Shift and Image Alignment
settings on the clipboard to a different aspect ratio and/or screen, do either of the
following:
• Switch to another aspect ratio (for example, from 16:9 to Cinema).
• Switch from Screen 1 to Screen 2 or vice versa.
Then, select Paste Settings from the Copy/Paste Aspect Ratio menu. The new settings
are saved automatically.
Output Shift: The controls in the Output Shift menu are similar to those in the Input
Position menu, except that they change the characteristics of the output signal. These
settings are saved independently for each aspect ratio.
Image Alignment: The Image Alignment menu provides precise, nine-point control over
the displayed image geometry. Use these controls as (and only if) needed to re-position
the image corners, mid-points and center to eliminate “keystoning” (mis-aligned corners)
or “pincushion” distortion (mid-points not aligned with corners). See Figure 4-8.
