This function is not available in split screen display of the TWO WINDOW function. (CROSS HATCH is not
affected.)Underlined values indicate factory defaults.
*1 This setting is turned “ON” when receiving marker control in REMOTE operation. (GPI, if set, has priority.)
*2 These settings are disabled when the GPI function ( Jpage 48) is used to control the marker setting. 
They are also disabled in split screen mode. 
*3 This setting is enabled only for HD and SD signal input in 16:9 aspect ratio mode. 
*4 TYPE1 and TYPE2 area marker size depends on the “MARKER TYPE” setting ( Jpage 23).

■CALIBRATION
The CALIBRATION function in this unit measures LCD panel characteristics from low to high brightness values
and internal monitor processing handles CALIBRATION. 
CALIBRATION does not rely on image quality settings since internal signals are used for a calibration.
CALIBRATION in this unit is made at D65 color temperature and calibrations for other color temperatures are
results calculated from this value.
■ Equipment required for calibration
Konica Minolta CA-210 display color analyzer
 Konica Minolta CA-PU12 or CA-PU15 standard measurement probe
 RS-232C cable (male to male, straight)
 Connect the RS-232C terminal on this unit to the RS-232C terminal on the CA-210 display color analyzer using a straight cable.
 Be sure to set the following calibration values on the CA-210 display color analyzer. The analyzer will not produce a correct calibration unless it has been calibrated. For details on setup procedures, refer to the CA-210 Users
Guide.
 Turn on this unit and perform adequate aging (about 1 hour) before starting calibration.
 Turn off the lights in the room and make sure that no external light can enter the standard measurement probe before starting the calibration. External light that enters the probe will prevent correct calibration of low brightness
characteristics.
 LCD panel characteristics and instrument error in the display color analyzer may sometimes result in small differences in values after calibration. 
In a fine tuning of the monitor, also set GAIN and BIAS for R, G and B in the COLOR TEMP. VAR mode.
 Do not apply the probe to a WFM/VECTOR display on the screen.  CA-210 side
