Correcting Keystone Distortion Of The Projection Screen; Adjustment Method - Olympus VP-1 - Data Projector - DLP User Manual

General Operation

Correcting Keystone Distortion of the Projection Screen

This adjustment is used when the projection screen is dis-
torted.
Note that extreme distortion cannot be corrected and in such cir-
cumstances the projector should be placed to face the screen
straight on beforehand.

Adjustment Method

(1) To adjust up-down distortion (e.g., Screen Example 1), press
the HKSTN button. The horizontal keystone adjustment dis-
play will appear.
H Keystone
To adjust left-right distortion (e.g., Screen Example 2), press
the VKSTN button. The vertical keystone adjustment display
will appear.
V Keystone
(2) While viewing the screen, press the (+) button or the (–) but-
ton and adjust the vertical or horizontal edges to be parallel.
In Screen Example 3, horizontal and vertical keystone distor-
tion should be adjusted.
(3) To close the display immediately, press the CANCEL button.
In the absence of operations for a period of about 10 sec-
onds, the display will close automatically.
Note
* The keystone adjustment values can be overwritten and saved. See "Keystone" on Page E-53(C).
* Overcompensation of the horizontal keystone correction value will result in a narrowing of the vertical
keystone adjustment range. Likewise, overcompensation of the vertical keystone correction value results in
a narrowed horizontal adjustment range.
* Note that the adjustment range will differ depending on the adjustment conditions.
* The screen examples have been depicted in an exaggerated form to aid in description.
