Adjusting The Keystone(Trapezoidal Distortion) - Panasonic PT-D9510E Operating Instructions Manual

Adjusting the keystone(Trapezoidal distortion)

• The KEYSTONE adjustment allows you to compensate for pictures' horizontal trapezoidal distortion.
(Keystone adjustment can not carried out in built-in test pattern.)
Adjustment procedure
–
• Adjust vertical linearity after adjusting horizontal keystone.
NOTE
The variable range of V LINEARITY changes with the H KEYSTONE adjustment setting.
• To reset H KEYSTONE and V LINEARITY to their respective factory default settings (H KEYSTONE:100
and V LINEARITY: 25), press the Standard (STD) button on the remote control.
• H KEYSTONE and V LINEARITY settings are reflected to other input signals as well.
• The keystone adjustment can compensate for trapezoidal distortion that corresponds to the projector's
elevation angle (to the screen) to within ± 10 °.
• As indicated below, two types of modes can be selected for keystone correction of luminance-
bandwidth-chrominance (YUV) signals (For the RGB system, there is only keystone correction using
digital processing).
YUV KEYSTONE:REAL: The original images are preserved as they are after keystone compensation
YUV KEYSTONE:BLANKING: Keystone correction is done with blanking, so part of the image
(In BLANKING mode, the adjustment range in blanking adjustment (page 52) is 0 to 255).
