Seagull correction
Use this correction only if, after adjusting the vertical lines with the
side bow or side keystone, still a ‘S’ deformation is visible on the
left and the right side of the image.
The default value on the bar scale for this correction is 50.
Push the control stick forward or backward to highlight SEAGULL
CORRECTION on the Left-Right menu and then press ENTER.
Eliminate the deformation by pushing the control stick to the left or
to the right until a straight line is obtained.
Left Side Correction
Left side corrections affect only the vertical lines of the set up pat-
tern. Only the green image is displayed while making the left side
adjust-ments. The red and blue images will automatically be cor-
rected in the same manner.
Convergence corrections are automatically disabled for the duration
of these adjustments.
Look only to the left side of the image while adjusting these fine
tunings (bow and keystone). Before starting the left side correction,
insure that the side bow and keystone adjustments are done prior
to these fine adjustments!
The following adjustments can be executed:
-
Left keystone
- Left bow
Push the control stick forward or backward to highlight LEFT SIDE
CORRECTION on the geometry menu and then press ENTER.
All adjustments are indicated on the screen with the function name,
a bar scale and a number between 0 and 100.
Adjust the next alignments until the vertical lines on the left side are
straight.
To enter an alignment, push the control
stick forward or backward to highlight a
function and press ENTER to activate this
function.
