Adjusting; Chroma/Phase Adjustment - Sony BVM-F250 Operation Manual

Adjusting

Before adjusting
The monitor must be warmed up sufficiently.
To perform stable color reproduction, turn on the power of
the monitor, display the white signal and leave it in this
state for more than 30 minutes.
About monitor adjustment
The monitor is used as a measuring instrument and is
required to faithfully reproduce the input signal. To
measure the signal accurately, the monitor must be
calibrated correctly using a reference signal.
To calibrate, adjust the following items in sequence.

1 Chroma/phase adjustment

You can save the adjustment value in Preset1 to
Preset5. The data of Preset1 to Preset5 is set to the
channel in the Picture Preset menu (page 58) of the
Channel Configuration menu.
Adjust the picture automatically with the auto chroma/
phase/matrix function for every signal format and
signal system to display the composite signal or Y/C
signal from the BKM-227W, or analog component
signal or analog RGB signal from the BKM-229X. If
the picture is not adjusted, the picture may not be
displayed correctly.
2 Color Temperature (white balance) adjustment
You can adjust the data set to the channel in the Color
Temp menu (page 58) of the Channel Configuration
menu.
You can adjust D93, D65 or User1 to User5.
3 Brightness/Contrast adjustment
You can save the adjustment value in Preset1 to
Preset5. The data of Preset1 to Preset5 is set to the
channel in the Picture Preset menu (page 58) of the
Channel Configuration menu.
Chroma/Phase Adjustment
Automatic adjustment (with auto chroma/phase/matrix
function) is required for each signal format, signal system
and matrix to display the composite or Y/C signal from the
BKM-227W, or the analog component or analog RGB
signal from the BKM-229X.
As you can automatically adjust the chroma, phase, matrix
and also 100% (white) and 0% (black) levels of the monitor
to the same as those of the reference signal by performing
the automatic adjustment, the automatic adjustment is also
effective for the RGB signal.
Perform the manual adjustment of chroma and phase to
adjust them further after automatic adjustment or to adjust
the digital signal from the standard input, BKM-220D,
BKM-243HS, BKM-244CC or BKM-250TG.
