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)
1. System setting (“Setting -” System setting””)
Condition setting for C330/C430
9 Sample-hold pulse
delay amount adjust-
ment
1) Input the black signal of XGA mode.
2) Select the following.
Group: OUTPUT3
Adjustment item: ENBR-DLY
G: ENBG-DLY
B: ENBB-DLY
1) Check the blur and ghost of characters of OUTPUT3.
2) Raise the ENBR-DLY value until pre-ghost appears on the left of
characters of OSD.
3) When the value is reduced by 1 to 2 points, pre-ghost disappears.
Set to the value reduced by 3 from the value where pre-ghost dis-
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.
10 RGB counter voltage
adjustment
1) Input the counter voltage adjustment
signal. (XGA)
2) Select the following.
Group: OUTPUT1
Adjustment item: R-COM
G-COM
B-COM
R-COM2
G-COM2
B-COM2
1) Adjust flicker using the operation SW or button on the remote con-
trol so that it becomes minimum.
2) When flicker appears on the screen unevenly, adjust the center
area considering the whole balance.
11 RGB white balance
adjustment
1) Input the RGB 50% gray signal.
(XGA60Hz)
2) Select the following.
Group: OUTPUT1
Adjustment item: R1-BLK (R)
B1-BLK (B)
1) 1. Adjust R1-BLK and B1-BLK so that the following chromaticity
values are obtained in the middle of the screen using CL200.
x = 294 ± 5, y = 327 ± 5
12 sRGB white balance
adjustment
1) Input the RGB 50% gray signal.
2) Select the following.
Group: OUTPUT1
Adjustment item: S-G1-BLK
S-B1-BLK
1) Adjust S-G1-BLK and S-B1-BLK so that the following chromaticity
values are obtained in the middle of the screen using CL200.
x = 322 ± 5, y = 341 ± 5
13 Auto keystone initial-
ization
1) Select the following.
Group: LINE
Adjustment item: Calibration
1) With the set placed on a level surface, press the ENTER key and
check that K-Sensor value is 0 ± 3 (125 - 3).
Check that keystone is caused by tilting the unit.
14 Model name writing 1) Write the model name with RS232C
command.
1) C430: MF_10000 (default)
C330: MF_10001
15 Tracking check 1) Input the RGB 10-step gray scale sig-
nal (inversion on top and bottom).
2) Select the following.
Group: OUTPUT3
Adjustment item: GAMMA
1) Check the lower gradation tracking.
When it is improper, optimize the GAMMA value.
1: Default (normal)
2: Red and blue down
3: Red and blue up
NOTE: When changing the GAMMA value, readjust the white bal-
ance.
16 Auto color shading
correction
1) Perform the auto color shading correc-
tion using the color shading correction
system (ccdc).
1) Check that remarkable color shading is not found on the screen.
System option
Simultaneous writing of 3D correction value: No (not checked)
Char transmission interval: 0 ms
Binary interval: 2 ms
Creation of correction value by linear correction factor: No (not checked)
Number of image captures (during adjustment or measurement): Twice
