AUTO 
SETUP H-POS/V-POS, H-SIZE/V-SIZE, DOT CLOCK and CLOCK PHASE are automatically adjusted when the 
RGB or PC signal is received.
This setting only operates when a PC signal or RGB signal is input, and \

h to a bright image  with borders and other objects are clearly shown, and then try auto setu\
p again.
•  Depending on the signal, out of alignment may occur after AUTO SETUP. Carry out  fi ne tuning for the 
position/size as required.
• If AUTO SETUP cannot set properly for vertical frequency 60Hz XGA signal (1024×768@60Hz and  1366×768@60Hz), pre-selecting the individual signal in “XGA MODE” (see page 39) may results in correct 
AUTO SETUP.
•  AUTO SETUP does not work well when a signal such as additional information is supe\
rimposed out of  valid image period or intervals between synchronizing and image signals \
are short.
•  If AUTO SETUP cannot adjust correctly, select “NORMALIZE” once and press ACTION (
) then adjust 
POS. /SIZE manually.
