This unit comes with a vertical and horizontal shift to suit most installations. Make sure that your installation
does not exceed 100% vertical offset and 43% horizontal offset to avoid trapezoidal correction.
This unit comes with a optical shift that features vertical and horizontal adjustment of the projection screen
position. Adjust the picture to your screen.
The Vertical Shift level is between -100% and 100% of the Screen Height (H).
The Horizontal Shift level is between -43% and 43% of the Screen Base (0.43 x B).
If the projector is not installed perpendicularly to the screen, use keystone correction to fulll your screen.

pictures, It is not recommended to use trapezoidal correction.
If you plan to use the vertical and horizontal shifts without keystone correction, make sure to not exceed the
values contained in the tab below:
Left / Right shift 0% 10% 20% 25% 30% 35% 43%
max. up / down shift 100% 87% 72% 58% 45% 22% 0%
