Runco VX-60d, VX-40d, VX-50d, VX-80d manual You must enter a passcode to access the Calibration menu

Operation

Use the 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 Calibration menu.

Note

To recall the ISF Night or ISF Day settings, select “ISF Night” or “ISF Day” from the ISF Presets menu (see above).

ISF Night - Display Color: Use the Display Color settings to adjust the projector lamp intensity. These settings are saved independently for each input.

•Lamp Power: Select Lamp Power from the Display Color Menu to adjust the lamp output level. You can choose to run the lamp as bright as possible (“100”), at its lowest power level (“0,” which equates to approximately 700 watts; this is the default setting) or choose a setting in between. Generally, lower lamp output prolongs the life of the lamp, but decreases brightness.

ISF Night - Input Image: The Input Image controls are similar to those in the Picture menu, but are accessible only by entering the Calibration menu passcode. This makes it possible to restore the picture quality settings to what they were when the projector was installed, simply by recalling the “ISF Night” preset.

ISF Night - Input Color: Use the Input Color controls to adjust the color balance of the incoming signal. These settings are also saved independently for each input.

•Gain: Use the Gain controls to correct color imbalances in the bright areas of the image. A good way to do this is to use a test pattern consisting mostly of solid white areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red, green or blue, decrease the Gain for that color.

•Offset: Use the Offset controls in the White Balance sub-menu to correct color imbalances in the dark areas of the image. A good way to do this is to use a test pattern consisting mostly of dark gray areas, such as a 30 IRE “window” pattern. If the gray areas contain traces of red, green or blue, decrease the Offset for that color.

•Chroma Delay: Use the Chroma Delay control to correct a mis-aligned image from a Composite, S-Video or Component video source. Chroma delay in an image causes color shifts to occur to the left of the vertical edge transitions, producing artificial shadows or a “halo” effect. If necessary, adjust this setting to eliminate them.

•Phase: Adjust the phase if the image (usually from an RGB source) shows shimmer or “noise.” Pixel phase adjusts the phase of the pixel sampling clock relative to the incoming signal. The effect of this control is similar to that of a tracking control on a VCR.

For best results, use a good test pattern such as a smooth gray consisting of a clear pattern of black and white pixels, or a similar “half on, half off” graphic image. (You may notice that you can stabilize the image at more than one point. Use either setting in this case.)

•Noise Filter: To apply noise filtering to the input signal, select Noise Filter from the Input Color menu. The Noise Filter is useful for clearing up noisy images from 480i video sources.

Use the left- or right-arrow buttons to select the desired amount of noise reduction, keeping in mind that higher settings (which reduce high frequencies) may also “soften” the image.
