➢
Please use [5X3], [9x5] & [17x9] for further geometry fine-tune and let all the grids in overlap area
with good grid stacking from two projectors.
➢
For curved screen, if there will be some difference in the grid size in adjacent projectors, user can
use Linearity Grid Line adjustment (in next section) to adjust the line gap and finish the image
position fine tune within shorter time.
➢
After finish Warp alignment, user can use [2x2] for complete image position fine tune without
changing the Warp result. If user executes [9x5] alignment again after [17x9] alignment, [17x9] grid
position will be reset and only keep [9x5] grid point information.
➢
In ideal condition, all grids in edge blending area between two adjacent projectors shall be aligned
together. In some special case, the vertical lines in edge blending area have some gap and can
’t
match 100%. Please try to align the grids near center of overlap region with good stacking. It
allows small image shift in both sides of the overlap region because edge blending will reduce the
effect of the mis-alignment in side borders. User can also adjust [Overlap] value in video wall
settings to compensate this deviation and keep reasonable image quality.
➢
After the above processes, if the grid p
attern in edge blending area still can’t stack together, user
can reduce one or two overlap grids from adjacent projectors to separate the adjusting points in
each projector and get more accurate geometry alignment result. If the result is still not good,
please use PC tool to apply 17x17 grid point adjustment. The adjusting result in remote controller
can be further adjusted through PC tool directly.
➢
Geometry alignment range from remote controller can be up to 600 pixels in [2x2] + 600 pixels
more in [3x3] for one corner/edge. If the adjustment range is too big, it is possible to get crashed
image, please try to execute some geometry alignment through projector geometry function of
minimize the image distortion through installation position shift.
➢
If geometry alignment range is too big, please adjust projector installation position or use projector
geometry alignment function to cover some adjustment.
➢
Ultra-short throw ratio projector is not suitable for curved screen display due to big image
distortion. Once user can execute geometry alignment to required position, the image quality will
be reduced, especially in the Text mode.
➢
After geometry alignment, all the grid patterns in overlap region should be stacked together.
