except they expand across displays in the defined array. See 3.7 Using Multiple
Projectors later in this section.
Figure 3.9. “Tiled” Resize Presets
“CUSTOM” RESIZE PRESETS
Custom appears in the list of available resize presets as an unnumbered
option. It occurs only when the values for Size and Vert Stretch (in the Size
and Position menu) are altered.
The values you choose for Custom will remain in the projector’s memory for
the current source, until they are modified.
NOTES: 1) When you are using your projector for the first time, Custom will
not appear in the list of Resize Presets or “Tiled” presets. This option only
appears when the values for Size and Vert Stretch are modified.
Size
Adjust Size when you want to change the image width and height
simultaneously, while maintaining the current aspect ratio of data from the
incoming signal. As you adjust the slidebar for Size, you will notice the value for
Vert Stretch changes accordingly and image proportion is maintained.
Vert Stretch
Adjust Vert Stretch (short for “Vertical Stretch”) when you want to adjust the
height of the image while maintaining the width of the image. By adjusting this
option, you will change the aspect ratio of the image. NOTE: Adjusting this
option does not change the value for Size.
Pixel Tracking
Use this option to adjust the frequency of the pixel sampling clock, indicated by
the number of pixels per line, so that all pixels generated by a particular source
are sampled. Proper pixel tracking ensures that the image quality – whether good
or not – is consistent across the screen, that aspect ratio is correct and that pixel
phase can be optimized.
Pixel tracking is adjusted most effectively using a good test pattern, such as a
smooth gray consisting of a clear pattern of tiny black and white dots, or a similar
“one pixel on, one pixel off” graphic image, such as the Windows shutdown
screen. Steady flickering or several soft vertical stripes or bands across the entire
image indicates poor pixel tracking. Adjust the slidebar until the stripes broaden
