➢
User can install IR extender receiver near screen for easy GeoBox operation. IR receiver extender
can be extended through audio cable up to 20 meters.
➢
Click channel selection key and [Pattern] key to show grid patterns in each channel. Press [Pattern]
key again will change grid color. To set different pattern colors in adjacent projectors will be more
convenient for geometry alignment.
➢
Please follow the sequence [2x2]
→
[3x3]
→
[5x3]
→
[9x5]
→
[17x9] to do geometry alignment to
ensure entire image will have uniform scaling factor.
➢
Apply [2X2] geometry alignment and draw the corners to expected locations. It doesn’t matter to
have some image inside the screen once it covers entire screen before 4 corner adjustment. [Warp]
alignment will adjust the image position back to the required position.
➢
If user doesn’t execute VNS Excel Spread Sheet calculation, please use [2x2] alignment and try to
let all projectors have similar image size with the overlap area having the same grid number.
➢
Apply [3x3 Curved] geometry alignment to let 9 adjusting points be located at the required position
including four corners, edge center points and center line position in each projector.
➢
Please use [5X3], [9x5] & [17x9] for further geometry alignment and fine-tune. Linearity Grid Line
adjustment function is convenient for complete grid line movement.
➢
After finish the alignment, user can use [2x2] for complete image position fine tune. 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 should be stacked
together.
➢
After the above processes, if the grid pa
ttern in edge blending area still can’t stack together, user
can reduce or increase overlapped grids to change the control point positions in overlapped area
and get more accurate geometry alignment result.
➢
PC tool can provide 17x17 grid point adjustment with quicker geometry alignment.
➢
After finish geometry alignment, all grids should be matched together.
