EXT OPTION Menu and Functions
FAN FULLMODE
Setting the cooling fan motor rotation speed
Switching ON "FAN FULLMODE", the rotation level of the fan becomes high-speed rotation (fixed). Moreover, when "FAN FULLMODE" is ON, changing "ALTITUDE" in OPTION becomes impossible (setting FAN FULLMODE is given priority more than ALTITUDE).
AUTO SETUP
Setting AUTO SETUP mode
NORMAL: To set the normal mode (the dot clock is adjusted strictly)
SPECIAL: To set the special mode (the dot clock is adjusted roughly)
Do not change the initial setting (NORMAL).
SELF CHECK
To enter the self-check mode
FLICKER ADJUST
To enter the flicker adjustment mode
525i SD
When non-standard signal of 525i/625i is inputted (AV amplifier, etc.), synchronization might be disordered according to connected equipment. In this case, set 525i SD to ON.
525p OS
When 525p/625p signal is inputted, reflection noise (vertical striated beat) might be generated according to connected equipment. In this case, set 525p OS to ON. However, the resolution decreases a little.
HPLL
When non-standard signal of VIDEO/S-VIDEO is inputted (VTR, VHD, etc.), horizontal synchronization might be disordered according to connected equipment. In this case, set HPLL to OFF.
