Notes:
• Perform the following adjustments after completing the Contrast and White Balance adjustments.
• Set the PICTURE SUB ADJ. data in the Setup Menu to “00”.
• The value adjusted at the SR adjustment becomes the reference value for the following adjustments. When this data
is changed, it is required to re-adjust the data of all of the adjustment signals (HDTV, SDTV and NTSC/PAL). When re-
adjusting the 1080/60i signal, use the SI.
• When overscan data of a signal is changed, it is required to re-adjust the underscan data of the same adjustment
signal.
• After completing the brightness adjustments, make sure that the Low-Light is not deviated. If it is, it is required to
perform the Low-Light adjustment again.
