The final performance will be a combination of many factors—projector characteristics,
projector setting, screen, ambient light and EdgePro setting.
Banding in overlap area under dark environment is caused by light leakage in the projector optic
system. It is not possible to be fixed by signal manipulation. The only way is to raise the black
level in none overlap area through [Offset] menu.
EdgePro edge blending gamma setting range is from 0.9-3.0 and default setting is 2.2 gamma
curve. Select projector display mode near 2.2 gamma setting to get the best results.
The projector may retain light leakage near the border (about 20 pixels) of the imager (micro
display—DMD or LCD). It is not possible to be fixed.
The factors affect final image quality
1.
EdgePro settings:
•
Edge Blending settings: Gamma (Transition, Gain), Shift (at “–“ value), Offset,
Color
•
Image Properties: To select Preset Mode to Neutral, sRGB or Bluish
•
Individual projector color adjustment by [Color] function under [Edge Blend]
menu.
2.
Projector:
•
Ultra-short throw ratio projector is not recommended for edge blending,
especially in curved screen edge blending.
•
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
•
To rest projectors with the same settings.
•
To select Display Mode. Usually Standard, sRGB/Neutral will get better result.
•
To disable projector Brilliant color adjustment or Dynamic color adjustment.
