Integrator mode
17) Initial reset setting mode (total adjustment)
This function restores adjusted values for PICTURE PARAMETER and WHITE BALANCE to factory-preset values,
which are within the range of values currently held in the selected memory area. Selecting "YES" with the remote
control 2 button or operation panel + button restores factory-preset values. Selecting "NO" with the remote control 3
button or operation panel – button restores the current state. Select the following:
"YES" to restore factory-preset values
"NO" to avoid restoring factory-preset values
and press the SET button.
In either case, you are returned to the above adjustment mode when selection is complete.
18) PC-9800 mask
This function selects the color of the mask section at the top and bottom of the screen when PC-9800 is input with
input function of RGB 1 or RGB 2.
Black
or
gray
The display is factory-set to black.
This function can be set only through RS-232C commands.
Activate RS-232C adjustment mode and
Send a <MKB> command to set the black mask section.
Send a <MKG> command to set the gray mask section.
Depending on the input signal, the rate of phosphor deterioration in the masked section may differ from that in the
unmasked section. For example, a display with mask section color set to BLACK that receives PC-9800 signals and
rarely displays a 480-full-line display will suffer no phosphor deterioration in the top and bottom mask sections and
demonstrate better luminance and white-balance for the full 480-line display than for other 400-line displays.
