2.6 Focus
2.6.1 区 Pattern
(1) If pattern can be uniformly focused (not worse than Limit
Sample), then pass!
(2) If it’s difficult to judge, then check 2.6.2
2.6.2 Defocus and Flare
Defocus: R<=3.5; G<=3.5; B<=3.5 pixel
Flare: R<=4.0; G<=4.0; B<=4.0 pixel
Slight flare is not counted as flare.

2.9 Dynamic Contrast Ratio
(DCR)
1. When RGB value of content input is smaller
than 20%, system will automatically switch to Eco mode, if
RGB value is greater than 60%, the projector will back to
Normal mode.
2. When DCR function turns on, lamp mode function is
grayed out to disable; when DCR function turns off, lamp
mode would return to setting value.
(Viewsonic agreed to take reliability and noise impact
caused by DCR function, but detailed specification of DCR
above would be finalized to suitable for reducing reliability
and noise impact by Qisda after PVT sample)
