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.
Note
* The keystone adjustment values can be overwritten and saved. See “Keystone” on Page E-53.
* 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.
