7.8. Final image quality fine-tune
➢
The final performance will be a combination of many factors
—projector characteristics, projector
setting, screen, ambient light and GeoBox setting.
➢
Banding in overlap area under dark environment is caused by light leakage in the projector optic
system. User needs to uplift the black level in none overlap area through [Offset] menu.
➢
The projector may retain light leakage near the border (about 20 pixels) of the imager (micro
display
—DMD, LCOS or LCD). It is not possible to be fixed.

Projector:
-
To select projector display mode near 2.2 gamma setting will get the best result.
-
Ultra-short throw ratio projector is not recommended for edge blending, especially in
curved screen edge blending.
-
When using ultra-short throw projectors, the reflection angle in overlap area will be very
big. Viewer will see different color banding when watch the image from different viewing
angle especially the screen gain value is more than 1.0.
-
To reserve enough overlap area
—0.6m-1.2m in width or 20%-40% (based on single
projector native resolution) is recommended.
-
To adjust image position of the projector and reduce keystone angle.
-
Increase Overlap region & reduce off axis angle
-
