Notes: • Perform the following adjustments after completing the Contrast and White Balance adjustments.
• Set the SUB PICTURE ADJ. data in the Setup Menu to “00”.
• The value adjusted at the SO 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.
