■ RGB Bias and Gain
Select this submenu to fine-tune the monitor’s color balance (R, G, B). This should only be done by someone
experienced with video engineering, as this will alter the overall color shading of the screen. The purpose is to allow
color matching to other types of monitors and/or displays. Note: The Color Temperature preset will automatically
switch to USER when Color Bias settings are adjusted. It is normal for color bias adjustments to be very subtle.
When selecting the RGB Bias and Gain submenu, gain adjustment indicators will appear at the top of the screen, and
bias adjustment indicators will appear at the bottom of the screen:
Use the
▲
and
▼
buttons to select each individual bias or gain control. Press SELECT to begin adjusting the control. Use
the ▲ and ▼ buttons to increase or decrease the value.
Alternately, the image adjustment buttons (Brightness, Color, Contrast) can be used to easily adjust the bias and gain
settings as shown below. The buttons affect whichever row of controls (gain or bias) is currently selected.
■ Check Field
Use the check field modes for monitor calibration or to analyze individual color components of an image. In
Monochrome mode, all color is disabled and only a grayscale image is shown. In Blue, Green, and Red check field
modes, only the selected color will be shown.
Use the following procedure when calibrating the monitor to SMPTE color bars with the following procedure:
1. Allow the monitor to warm up for at least 5-10 minutes.
2.
Display SMPTE split-field color bars on the monitor using an external source.
3.
Enable Monochrome mode.
4.
Locate the pluge pattern (super black, black, and gray bars) at the lower-right corner of the screen. Adjust the Brightness knob until
there is no visible difference between the super black and black bars, but the gray bar is still visible.
5.
Adjust the Contrast knob until an even grayscale appears along the top bars.
