Section 3: Operation

Tiling Full Screen, Tiling Full Width, Tiling Full Height and Tiling Anamorphic. These options are essentially the same as the ones described above 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
