ISF Calibration Use the ISF Calibration menu to perform advanced picture quality adjustments. This menu
should be used by ISF-certified technicians only.
Picture Adjust: The controls in this menu are identical to those in the main Picture Adjust
menu, but are accessible only by entering the ISF Calibration menu passcode. This makes it
possible to restore the picture quality settings to what they were when the DView was
installed, simply by recalling the “ISF Night” or “ISF Day” preset.
•Brightness: Refer to Brightness on page 31.
•Contrast: Refer to Contrast on page 32.
• Color: Refer to Color Saturation on page 33.
•Tint: Refer to Tint on page 33.
•Sharpness: Refer to Sharpness on page 34.
• ADC Phase Adj.: This control works similarly to the Phase adjustment for RGB signals
(refer to
Phase on page 38). Use it to improve the apparent sharpness of 720p and
lower-resolution Component, S-Video or Composite sources. For best results, adjust ADC
Phase while displaying a “Sharpness” pattern (
Figure 4-5).
• DNR: Refer to DNR on page 34.
• MPEG NR: Refer to MPEG NR on page 34.
• Backlight: Refer to Backlight on page 34.
• Color Temp.: Refer to Color Temperature on page 34.
• Gamma: Refer to Gamma on page 35.
• Black Level: This control compensates for incoming elevated black levels present in
certain video signals. The default setting (32) results in a minimum black level of
approximately 0
IRE. Adjust as needed to match the dynamic range of the source; increase
the value if blacks appear elevated (dark gray). If blacks appear “crushed” (too dark), use a
lower settting.
