1. DISPLAY ALIGNMENT
A. TIMING & DISPLAY SIZE
For all presetting mode shall be within the limitation:
H. WIDTH
310 ± 5mm
V. HEIGHT
232 ± 3 mm
The external control range of the data area, shall be as follows;
Max. horizontal size
: full the screen
Max. vertical size : full the screen
B. PICTURE POSITION
For all presetting mode shall be within the limitation:
H.PHASE
SCREEN CENTER ± 4 mm
V.CENTER
SCREEN CENTER ± 3 mm
C. LINEARITY
The linearity of an image displayed on the CRT must meet the following requirements, with reference to figure
4.05 for both X and Y and axis.
The measured value of linearity shall be less than 6%(p) or 8%(s) when calculated using all lattices and shall be
less than 5%(p) or 6%(s) when calculated using adjcent lattices.
Xmax-Xmin OR
Ymax-Ymin
Xmax+Xmin
Ymax+Ymin
Where: Xmax,Xmin,be Calculated Same Line
Ymax,Ymin,be Calculated Same Row
D. ALIGNMENT PROCEDURE
•
Warm up the monitor for at least 30 minutes before adjustment.
•
Set the front of CRT to the east.
•
Turn all VR set to center position.
