HT211z Projection Throw Distance
Thank you for choosing Knöll projectors! The HT211z projector uses digital light processing chip to give
bright clear images. Its lens allows for a limited amount of zooming.
When ceiling mounting the HT211z the Knöll C 21 mount kit is easy to install and swivels for exact
placement. It drops the projector about 3" and the projector lens is about 5" from the ceiling. If more of a drop
is needed, the C 20+6 extender adds an extra 6" drop. As many C 20+6 can be added as needed.
The most frequently asked questions concerning HT211z DLP projector is:
How much can the projector be tilted up or down (when ceiling mounted or floor mounted)?
About 10 degrees. The HT211z projector features adjustable keystone. Ideally the projector should be as near
to level as possible with the screen drop as shown below.
Is the width of the 4:3 image the same as the 16:9 image?
Yes. When changing from a 4:3 to a 16:9 image the width stays the same, just the 16:9 image is on the 4:3
image with black rectangular boxes above and below the 16:9 image.
Projection throw distances are the distances from the projector lens to the screen. If the
projector is mounted level (this is recommended) the image will drop (ceiling mounted
projector) or rise (floor mounted projector). The drop or rise is the vertical distance from
the projector lens to the bottom (floor mounted projector) of the image or the top (ceiling
mounted projector) of the image. The center of the image will be tilted up 13 degrees if the
projector is floor mounted, level and the keystone is set to 0.
