Correcting On-Screen Color; Correcting Color Convergence Using Ecc - Christie CineLife+ CP4415-RGB Installation And Setup Manual

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.
8. When complete, push in all the convergence adjustment knobs to disengage them.
If the colors at the corners of the screen require further correction, see Correcting color
convergence using ECC (on page 78).

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.
For more information on managing color settings, see the CineLife+ User Guide (P/N: 020-103073-
XX).

Correcting color convergence using ECC

Use electronic color convergence (ECC) to correct the color convergence across the screen by
correcting four discrete points at the corners of the screen.
Perform ECC only when satisfied with the position of the image on the screen.
1. In the left navigation menu, select Image Settings > ILS File Setup.
2. Use the arrow to select an ILS file to store the ECC settings.
3. On the ILS File Setup page, select ECC.
Each corner of the screen displays three separate sprites, one for each primary color. The user
interface displays the Test Pattern controls.
4. Set the Screen Type to Flat or Scope.
This sets the test pattern and the location of the sprites on the screen. Each sprite appears as
the letter L.
5. Set the Sprite Color to Move and Show.
When first opening the ECC, all Show and all Move colors are selected, so all three sprites are
displayed and all three sprites are moved by the directional pad.
6. Select a Step Size to control the granularity of the steps from coarse (1/8 pixel per step) to
fine (1/64 pixel per step) when using the directional pad.
Sprites can be moved a maximum of 20 pixels.
7. Choose a corner by selecting the circle at a corner of the dashed rectangle.
