Chapter 4—Setup Adjustments
HJT Model 100 User's Guide 4-35
Recheck the Sensitivity adjustment to locate this specific area, if
possible, and increase or decrease its level accordingly. If this is not
possible, the Shading procedure may have to be repeated.
4. If necessary, recheck and readjust threshold color balance.
To adjust the Threshold Offset for the best color balance:
1. Toggle the RGB
KEY
and select the color that is too prominent in the
dark bars .
2. Access T
HRESHOLD
O
FFSET
from the C
ONVERGENCE MENU
.
3. Use the up/down arrow keys to slightly increase or decrease the
Threshold Offset so the darkest bars in the test pattern are without
color, i.e. grey. Make a note of the offset setting before making any
adjustments in case an error is made and original setting is needed.
Recheck the test pattern for a normal, gradual transition from bar to
bar. If increasing the Offset, avoid overadjusting any of the colors.
Leave a normal, gradual brightness transition between the two
brightest bars.
NOTE: The two (2) numbers that appear in the box on the screen
represent the lowest and highest Threshold settings on the screen. If
either of these settings is at the minimum (0) or maximum (255) there
will be no adjustment range available to adjust the Offset. This means
that one (1) area on the screen has been adjusted too high or too low
during the Threshold adjustment and is restricting the Offset
adjustment.
Before the Offset can be adjusted, this area must be increased or
decreased to allow for more range to perform the Offset adjustment.
Recheck the Threshold adjustment to locate this specific area, if
possible, and increase or decrease its level accordingly. If this is not
possible, the Color Balance procedure may have to be repeated.
4. If necessary, recheck and readjust the Sensitivity Color Balance.
4.9. Picture Settings
Picture settings affect the image quality. Brightness and Contrast can be
adjusted for any type of source. Color Tint, and Sharpness are only active with
non RGB-type VICs. Complete color balancing before adjusting these settings.
