Correcting On-Screen Color - Christie CP4315-RGB Installation And Setup Manual

6. Use the Convergence test pattern to assist with adjusting the horizontal and vertical lines.
Horizontal adjustments are controlled by adjusting knob 3.
Vertical convergence and rotation are controlled by adjusting knobs 1 and 2. Christie
recommends rotating a single knob a maximum of a quarter rotation before adjusting the
second knob a quarter rotation. For example, if using one hand, turn the left knob a quarter
rotation and then the right knob a quarter rotation, and so on. Adjusting a single knob for
vertical or rotational adjustment to an extreme before adjusting the second knob may result in
the convergence mechanism binding.
For the best stability, Christie recommends setting convergence while rotating the knobs in a
clockwise direction. This may require first adjusting convergence by turning the knobs counter-
clockwise, and finalizing the convergence with a clockwise approach. This applies to all knobs.
7. When complete, push in all the convergence adjustment knobs to disengage them.

Correcting on-screen color

After installation, further image adjustments may be required to correct color on the screen.
The next steps may include creating a Measured Color Gamut Data (MCDG) file and configuring a
Pureformity Color ™ Technology (PCT) file to achieve optimal color and brightness uniformity.
