XGA: 6, 7, 9, 10

,
12 (no 8 grids);
WXGA: 7, 8, 9, 11, 12, 13, 14 (no 10 grids);
1080p: 9, 10, 11, 12, 13, 17, 18, 19, 20 (no 15 grids).
Please calculate the pixel number based on 1 grid=32 pixels.
-
Please ensure
the grid between
the
two adjacent projectors
are aligned
together,
this will esure great
results on the final output
. Horizontal lines
in the grid alignment s
hould be 100% match together.
The vertical lines are allowed to be separated. However these vertical lines should keep the same gaps
between two adjacent projectors.
User can adjust
Video Wall
[Overlap] value to compensate the gap distance and get crisp image.
[
Edge Blend
]
•
T
o merge the images from multiple projectors to become one seamless image.
•
Ensure t
he scaling factor between two adjacent images shall be the same. Otherwise,
the image will
be
blurred.
T
he image size
should be related to the input
resolution.
•
Geometry alignment before edge blending is required:
- To let the image has the same grid size (same scaling factor in both horizontal and
vertical directions)
-To let the images overlap together in horizontal lines
•
Sub-menu under [Edge Blend] menu
-
[Edge]: select the right edge and set overlap pixels
-
[Gamma]: select correct gamma for overlapped area and [Offset] compensation
area to eliminate
banding effect.
- [Offset]: to do black level uplift in non-overlapped area to compensate light
leakage in projectors.
- [Shift]: shift the location in edge blend area. In some case, it may help color fine-tune.
- [Corner]: to do precise [Offset] location alignment.
- [Color]: to do discrete color adjustment for individual projector.
[
Edge Blend
]
- Selection and Settings
•
[Edge] is to select the edge for edge blend
ing
and set
the
overlapped pixel number.
•
The unit can perform
edge blending
on
any edge.
N
ote: Max. edge blend pixels are
8
00.
I
f over this number, please consider using image stack or change
aspect ratio in projector to shrink projection image.
