2. Cautions for 3D color shading correction/adjustment
The following measurement and adjustment must be performed under the same conditions using the following:
• Dark room (Block out stray light.)
• Diffuse reflection (mat type) screen
The setting of the projector must be performed under the following conditions:
• Power save disabled (to keep the lamp stable during measurement)
• Auto search canceled (to fix to INPUT1)
• RGB mode of the input terminal COMPUTER1 (component mode canceled - just to be sure)

appears.
(Set to 16 in the following case: When the ENBR-DLY value is 20, 
pre-ghost appears; when it is 19, pre-ghost disappears.)
4) Adjust green and blue in the same way.
NOTE: EPSON panels may vary by 1 to 2 points from lot to lot. To 
improve the ghost quality, perform this adjustment.

2. Teaching
Basically, teaching should be measured only once from model to model. However, if the optical characteristics of the set are changed significantly,
it is necessary to reset the conditions according to changes and to perform remeasurement.
Measurement method of correction factor
1) Determine the standard set of C330/C430. Each one unit (n units)
2) Switch the set to the RGB mode of the input terminal COMPUTER1.
3) Execute teaching of the standard set under the following conditions.
Condition setting for C330/C430
3. Color shading correction (adjustment)
Condition setting for C330/C430
Correction method
Select the model name created in the section (2) and perform color shading correction/adjustment.
If the set has significantly different optical characteristics from the standard or shows color shading or line dropouts, execute teaching and adjust it
using the correction factor.
