The projectors meeting the following conditions are applicable :

Minimum optical power no less than 1500 Lumen, which can be sele cted in accordance with the size of
a room.
Why is the image projected by the projector in the shape of the
wrong size or distorted and how to adjust it?
If, after orienting, you find that the projected image does not properly fill the screen, or suffers from
distortion or shimmering, the resolution settings of your projector and your computer may not match.
It’s very important that the computer and projector resolutions correspond exactly.
Ensure that the projector is set to its optimal image resolution. Refer to your projector’s manual for the
true resolution of your projector and reset it if necessary. While the projector manual instructions may
indicate that resolutions other than the optimal one are permitted, you should not set the resolution to
any of these other settings.
When the projector is not placed properly, the image projected on the whiteboard may turn out to be
a keystone. When the projector is placed front higher or rear higher, a vertical trapezium is projected.
