Pattern
(1)If pattern can be uniformly focused, pass!
(2)If not, check 2.6.2
2.6.2 Defocus and Flare
Defocus:
R<=3.0
; G<=2.5; B<=2.5 pixel
Flare:
R<=4.0
; G<=3.5; B<=3.5 pixel
Slight flare is not counted as flare.

2.8 Image Quality
2.8.1 DMD Image Quality
See Appendix D
2.8.2 Image Imperfection
See Appendix D Blemish
2.8.3 Image Shadow or Blur
Procedure:
1. 53” (Diagonal at 2m, Wide) image size.
2. Default preset mode “ Dynamic”
3. Full white pattern to check the image.
Let the projector on the desk (don’t move it up/down or left/
right) and just inspect the pattern. It is OK If the shadow or blur
can not be observed obviously.
4. If there is blur obviously, Measure brightness of point A and
brightness of point B. A/B must larger than 80%.detail
