Use the ISF Calibration menu to perform advanced picture quality adjustments. This menu

should be used by ISF-certified technicians only.

You must enter a passcode to access the ISF Calibration menu.

Note

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 29.

•Contrast: Refer to Contrast on page 30.

•Color: Refer to Color Saturation on page 31.

•Tint: Refer to Tint on page 31.

•Sharpness: Refer to Sharpness on page 32.

•ADC Phase Adj.: This control works similarly to the Phase adjustment for RGB signals (refer to Phase on page 36). 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 32.

•MPEG NR: Refer to MPEG NR on page 32.

•Backlight: Refer to Backlight on page 32.

•Color Temp.: To choose a color temperature setting, select Color Temp. from the Picture Adjust menu and press ENTER. (Color temperature defines the “color of gray.”) The choices are 5400K, 6500K, 8500K and Custom. The default setting, 6500K, is appropriate for most situations. Higher settings produce a “bluer” picture; lower ones impart a reddish hue to the image.

Each color temperature setting has six (6) “white balance” parameters associated with it (two each for red, green and blue). (The White Balance settings for the 5400K, 6500K and 8500K color temperatures are factory-set and cannot be changed.)

To create a “Custom” color temperature, select Custom from the Color Tip Temp. menu and press ENTER. Then, press ENTER a second time to go

directly to the White Balance menu. (This shortcut is available only from the ISF Calibration menu.)

•Gamma: Refer to Gamma on page 33.

•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.

The VL-52 features a 52-inch screen size, while the VL-57 sports a larger 57-inch display, both offering expansive viewing areas ideal for home cinema setups. One of the key characteristics of these models is their use of a high-resolution CRT (Cathode Ray Tube) technology, which provides vibrant colors and deep blacks, enhancing the overall image quality. The zoned convergence adjustment allows users to fine-tune the picture, ensuring that colors align perfectly across the entire screen.

In terms of features, both models support various video formats, including 480i, 480p, and 1080i, allowing for high-definition viewing on compatible content. The inclusion of multiple inputs, such as component, composite, and S-Video, ensures that users can connect a variety of devices, from DVD players to gaming consoles, easily. This versatility makes the VL-52 and VL-57 attractive options for consumers seeking a comprehensive entertainment solution.

The technologies integrated into these models also contribute to their performance. The onboard video processing capabilities enhance image clarity and reduce motion blur, making fast-paced action scenes more enjoyable. Furthermore, both models are equipped with an advanced color management system, which ensures that colors remain true to the source material, providing viewers with a lifelike experience that is reminiscent of the cinema.

Another noteworthy characteristic is the build quality. The Vidikron VL-52 and VL-57 feature a robust and elegant design, making them a fitting centerpiece in any home theater setup. The attractive cabinet work and premium materials used in their construction reflect the brand's commitment to quality and aesthetics.

Overall, the Vidikron VL-52 and VL-57 remain iconic models, blending technology, performance, and design.
