OPERATION
Changes made to the Scaling Parameters menu are applied immediately and are saved when you exit the menu (press Exit 
or Menu 
).
H & V Scaling: Controls the image width and height in tandem, maintaining the orginal aspect ratio (proportion) of data from the incoming signal.
Vertical Scaling:
Vertical scaling adjusts the height the image while keeping the width constant. Use Vertical Scaling to display data from the incoming signal in a different aspect ratio.
Total H Dots:
(SHORT CUT: Press Pixel 
and adjust the top slidebar.)
Total H Dots adjusts the frequency of the pixel sampling clock, indicated by the number of pix- els per line, so that all pixels generated by a particular source are sampled. Proper pixel tracking ensures that the image
NOTE: By default, the projector will sample at the correct frequency for most sources.
Total H Dots is adjusted most effectively using a good test pattern, such as a smooth gray con- sisting of a clear pattern of tiny black and white dots, or a similar “half on, half off” graphic image, such as the Windows shutdown screen. Steady flickering or several soft vertical stripes or bands across the entire image indicates poor horizontal dots. Adjust the slidebar until the stripes broaden to the point where one large stripe fills the image. Again, the image may still exhibit some noise. See Fine V Dots.
Fine V Dots
(SHORT CUT: Press
Pixel | and adjust the bottom slidebar.) |
Fine V Dots adjusts the phase of the vertical dots sampling clock relative to the incoming sig- nal. It is used primarily for adjusting RGB inputs.
NOTE: Adjust Fine V dots after Totat H dots is properly set.
Adjust Fine V Dots when the image (usually from an RGB source) shows shimmer or “noise”. Fine V Dots adjustment is done most effectively from within a proper test pattern, such as a smooth gray consisting of a clear pattern of tiny black and white dots, or a similar graphic image. Adjust until the image is stable and each dot is clearly defined. Using the numbers on the slide- bar as a guide, you will notice that you can actually stabilize the image at more than one point- i.e., you may find that the image appearance at “11” is identical to the image appearance at “38”, thus you can select either setting.
