moved beyond the bottom-right corner of the output are removed. For the size TOPL and
BTMR commands, the appropriate image corner is moved toward the center of the screen,
to allow the size to be set accurately.
The size SIZE and POS (position) commands can be used in conjunction with, or in place
of, the size
TOPL
and
BTMR
commands. The size
SIZE
command scales both horizontally
and vertically. The size POS command moves the input image like size TOPL . However,
the image is shown in its normal position, without repositioning it toward the center as
with the size
TOPL command.

Y/C Delay (Formerly called CPHASE)
Adjust the horizontal Chroma timing in relation to Luma. It is suggested that the Y/C-
delay calibration image on the Video Essentials™ disk (title 17, chapter 24), or the AVIA
Y/C-delay test image in the Special Tests section of Advanced AVIA, be used to
calibrate the Chroma phase.

Sharpness
This command is used to adjust the sharpness of the input image. It is almost always best
to leave this at the factory default setting, especially for SVideo and component inputs.
The command format is:
MENU → IN → ADJ → SHARP →

Input Black Pedestal
Note:
For best video quality, the Input Black Pedestal must be set correctly. For Composite and
SVideo sources, 7.5 IRE is generally correct. Many component sources use 0 IRE. Check
the manual of the source device to be sure which setting is correct. If unsure, use 0 IRE.
This command specifies if there is an input black pedestal. The command format is:
MENU → IN → ADJ → PDSTL →
(
7.5 IRE, 0 IRE
),
OK
Input Black Enhance
This command expands the lowest 2% of the input range (0 to 2 IRE) slightly. This can
help to make black backgrounds appear darker verses the 4 IRE level used in some
PLUGE patterns. The command format is:
MENU → IN → ADJ → ENHNCE →
(
BLACK, OFF
),
OK
