Confirming the full white luminance

Carry out the following confirmation in FACTORY mode (as the back raster luminance of Euro-
pean model declines in NORMAL mode).

2.5.1.14

Confirming CONVERGENCE compensation function

Confirm that CONVERGENCE changes by varying HORIZONTAL and VERTICAL BASIC CON-
VERGENCE.

Lluminance/color
indicator
coordination uniformity
The luminance ratio between the center and periphery must be 80% or more with timing No. 12
(106.25kHz/85Hz, 1600 x 1200) COLOR 1.
The color coordination difference between the center and periphery must be ∆x, y < ±0.012 at
COLOR 1 / sRGB / 5.
2.5.1.17

Confirming the full white color coordination

Carry out the following confirmation in FACTORY mode (as the back raster luminance of Euro-
pean model declines in NORMAL mode).
Confirm that the color coordination at the center of the full white is within the following range at
timing No.12 (106.25kHz/85Hz, 1600 x 1200).
