From the Output Menu, select Output Adjust to scale the entire output to fit the theatre’s
physical setup (e.g., curtains, drapes, and off-axis projection).
Figure 4-19. Output Adjust Menu (sample)
This adjustment must be performed while you view the projector’s output on your screen.
When you enter this menu, a solid white raster box appears at the size and position
specified within the menu. The selected input is temporarily turned off, and the output
video is black. As you adjust H and V size and position, the raster box adjusts accordingly.
When you exit the menu, the raster box is cleared, and the selected input will be scaled to
fit within this exact size and position.
The following functions are available:
• H Size — adjusts the horizontal size in pixels.
• V Size — adjusts the vertical size in lines.
• H Position — this field is bracketed when H Size is 2048. When you adjust H
Size below 2048, this field becomes active, enabling you to adjust horizontal
position in pixels. Positioning is limited to the overall 2048 “space,” and the image
cannot be moved off screen.
• V Position — this field is bracketed when V Size is 1080. When you adjust V
Size below 1080, this field becomes active, enabling you to adjust vertical position
in lines. Positioning is limited to the overall 1080 “space,” and the image cannot
be moved off screen.
• Reset All — resets H and V Size to 2048 x 1080, and H and V Position to [0].
