Dell Projector to Displays Upwards Instead of Horizontally Level




Verify the projector height is consistent with the projector throw.

Some projectors use a telecentric throw, meaning the image is projected directly horizontal to the position of the projector. Dell projectors have a non-telecentric throw, which positions them to be in use for the business presentation environment. A non-telecentric throw displays the image at an angle up from the lens of the projector. (Figure 1)

NOTE: If the projector is mounted too high, the image may be displayed on or near the ceiling. This is normal and the height must be lowered to display correctly. If additional mounting height is needed, the projector should be mounted with a Dell-approved ceiling mount kit.

NOTE: Because of the lens design, measurements may vary slightly from projector to projector. The exact measurements are stated in the Users Guide.


Verify the Distance From the Projector to the Display

Viewing the projector image at the correct distance will allow optimal clarity with the image.

To view at the correct distance, perform the following steps:

Note:
Viewing the image closer 1.5 times the width of the image can be attempted but an appearance of a blurry image may occur.
  1. Measure the diagonal width of the image that is being displayed by the projector.
  2. Verify the viewing distance from the display is at least 1.5 times the diagonal width of the image.
