Projection Operations z Note that auto keystone correction is possible within a range of about -30 degrees to +30 degrees. Screen Up to about 30 degrees Up to about 30 degrees z Auto keystone correction is performed by detecting the elevation angle of the projector. This means that the surface you are projecting onto needs to be standing straight up. If the surface you are projecting onto is not straight, use manual keystone correction to correct the image. z You can turn auto keystone correction on or off as required. For details, see "Option Settings J Auto Keystone Correction" on page 89. z Note that auto keystone correction is not performed for horizontal keystoning. Use manual correction for horizontal keystoning. z Performing manual horizontal keystone correction and then automatic keystone correction can cause the manual horizontal keystone correction value to change, and can magnify horizontal keystoning. This occurs when vertical keystone correction narrows the allowable manual horizontal keystone correction range, causing the manually specified correction value to be outside the correction range. If this happens, rearrange the projector and screen so the lens is pointing straighter at the screen, and then perform manual keystone correction or auto keystone correction again. 51

Projection Operations
Note that auto keystone correction is possible within a range of about
–
30 degrees to
+30 degrees.
Auto keystone correction is performed by detecting the elevation angle of the projector.
This means that the surface you are projecting onto needs to be standing straight up. If
the surface you are projecting onto is not straight, use manual keystone correction to
correct the image.
You can turn auto keystone correction on or off as required. For details, see
“
Option
Settings
Auto Keystone Correction
”
on page 89.
Note that auto keystone correction is not performed for horizontal keystoning. Use manual
correction for horizontal keystoning.
Performing manual horizontal keystone correction and then automatic keystone correction
can cause the manual horizontal keystone correction value to change, and can magnify
horizontal keystoning. This occurs when vertical keystone correction narrows the allowable
manual horizontal keystone correction range, causing the manually specified correction
value to be outside the correction range.
If this happens, rearrange the projector and screen so the lens is pointing straighter at
the screen, and then perform manual keystone correction or auto keystone correction
again.
