Seagull Correction; Left Side Correction - Runco DTV-1101 Owner's Operating Manual

Seagull Correction

Use this correction only if, after adjusting the vertical lines with the side
bow or side keystone, an 'S' deformation is still 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 disk up or down to highlight SEAGULL CORREC-
TION on the Left-Right Menu and then press ENTER.
Eliminate the deformation by pushing the control disk 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 pattern.
Only the green image is displayed while making the left side adjust-
ments. The red and blue images will automatically be corrected 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,
ensure that the side bow and keystone adjustments are done
prior to these fine adjustments!

TION on the Geometry Menu and then press ENTER.

alignments until the vertical lines on the left side are straight.
