Adjust the Default Scan rate slider in the Projector Settings window so that the circle is just touching
the sides of the square. Note that sometimes the circle may touch only the sides but may be over on the
top and bottom, or vice versa. Just adjust the slider for the best overall appearance of circle touching the
square.
Using the ILDA Test Pattern to set the Color/Blanking shift
Just below the purple Y in the ILDA Test Pattern, there is a set of long horizontal lines around short
vertical lines. The ILDA tuning standard dictates that the horizontal lines should be approximately
centered around the vertical lines.
Color shift too low: Color shift correct: Color shift too high:
Horizontal lines Horizontal lines Horizontal lines
shifted too far left approximately centered shifted too far right
As you are projecting the ILDA test Pattern, look very carefully at the horizontal lines below the letter Y.
Adjust the Color/Blanking shift slider in the Projector Settings window so that the horizontal lines are
approximately centered around the vertical lines. Since the Color/Blanking shift is a somewhat coarse
adjustment, it may not be possible to get the horizontal lines perfectly centered around the vertical lines.
It is acceptable that the top set of horizontal lines be shifted slightly to the right -- lining up under the
letter Y.
Better scanners provide better results
Although QuickShow will work with any scanners and scan speed, QuickShow provides the best results
with 30K or faster scanners that are tuned perfectly. Please make sure that the low frequency damping
and high frequency damping are adjusted properly for "critical damping."
