Red image non-uniformity
In certain circumstances, the projection lens may have tolerance deficiencies that cause the normal
red image over-sizing to become slightly non-uniform. This non-uniformity generally appears on the
lower-right of the image causing a perceived clockwise twist in the lower-right corner only. The other
three corners appear normal.
•
To minimize the effect on the bottom of the screen, twist the image slightly counter-clockwise.
Keep the subtitle zone as converged as possible.
•
If the problem appears to be more than an extra 1/2 of a pixel out of uniformity, you may
need a new lens/prism assembly.
