Operation 34 Runco CL-420 Owner’s Operating Manual Picture Adjust Use the controls in the Picture Adjust menu to calibrate your CL-420 for optimum picture quality. The CL-420 has been designed to incorporate setup and calibration standards established by the Imaging Science Foundation (ISF). The ISF has developed carefully crafted, industry-recognized standards for optimal video performance and has implemented a training program for technicians and installers to use these standards to obtain optimal picture quality from Runco video display devices. Accordingly, Runco recommends that setup and calibration be performed by an ISF certified installation technician. All signal types require separate processing. Therefore, you need to calibrate each input separately. Runco recommends calibrating the CL-420 inputs in the following order: 1. Component 1 / Component 2 2. S-Video 3. Video 4. RGB-HD 5. DVI Although it may be possible to obtain satisfactory picture quality using the naked eye and regular program material, Runco recommends using the following calibration tools for best results: External test pattern source -- Sencore VP401 Multimedia Video Generator, Ovation Multimedia test DVD or equivalent. A blue filter (provided with many test DVDs), for color level and tint adjustments. Connect your test pattern source to the input that you are calibrating and proceed as follows. Perform the adjustments in the order listed here.

Operation Runco CL-420 Owner’s Operating Manual 35 Brightness: On your external test pattern source, select a PLUGE pattern. (PLUGE is an acronym for “Picture Line-Up Generation Equipment.”) Figure 4-5 shows a typical PLUGE pattern. Figure 4-5. Typical PLUGE Pattern for Adjusting Brightness PLUGE patterns vary but generally consist of some combination of black, white and gray areas against a black background. The example above includes two vertical bars and four shaded boxes. Select Brightness from the Picture Adjust menu. Using the left- and right-arrow ( ) buttons, adjust the brightness so that: The darkest black bars disappear into the background. The dark gray areas are barely visible. The lighter gray areas are clearly visible. The white areas are a comfortable level of true white. The image contains only black, gray and white (no color). Below Black Above Black
Operation 36 Runco CL-420 Owner’s Operating Manual Contrast: On your external test pattern source, select a stepped, gray-bar pattern like the one shown in Figure 4-6. Figure 4-6. Typical Gray Bar Pattern for Adjusting Contrast Select Contrast from the Picture Adjust menu. Using the left- and right-arrow ( ) buttons, adjust the contrast to a point just below which the white rectangle starts to increase in size. Color Saturation: On your external test pattern source, select a color bar pattern like the one shown in Figure 4-7. Figure 4-7. Typical Color Bar Pattern for Adjusting Color Saturation and Tint Brightness and contrast controls are interactive. A change to one may require a subtle change to the other in order to achieve the optimum setting. Note gray yellow cyan green magenta red blue
Operation Runco CL-420 Owner’s Operating Manual 37 Select Color from the Picture Adjust menu. While looking at the color bar pattern through a blue filter, adjust the color saturation level until the outermost (gray and blue) color bars appear to be a single shade of blue: Tint: Tint or “hue” is essentially the ratio of red to green in the color portion of the image. When tint is decreased, the image appears redder; when it is increased the image appears greener. To set the tint, select Tint from the Picture Adjust menu. While looking at the color bar pattern through a blue filter, adjust the tint level until the cyan and magenta color bars (on either side of the green bar) appear to be a single shade of blue. 1. Like the brightness and contrast controls, the color and tint controls are interactive. A change to one may require a subtle change to the other in order to achieve the optimum setting. 2. Color and tint controls are not available on the DVI or RGB-HD inputs. gray yellow cyan green magenta red blue Note
Operation 38 Runco CL-420 Owner’s Operating Manual Sharpness: “Sharpness” is the amount of high-frequency detail in the image. To adjust sharpness, select Sharpness from the Picture Adjust menu and press ENTER. On your external test pattern source, select a pattern like the one shown in Figure 4-8. Adjust as needed, looking for white edges around the transitions from black to gray and different sized lines in the “sweep” patterns at the top and bottom. Lower the sharpness setting to eliminate them. Figure 4-8. Typical Test Pattern for Adjusting Sharpness Gamma: The Gamma control determines how gray shades are displayed between minimum input (black) and maximum input (white) for all signals. A good gamma setting helps to optimize blacks and whites while ensuring smooth transitions for the “in-between” values utilized in other grays. Unlike brightness and contrast controls, Gamma allows you to lighten or darken the overall tone of your images without changing the extremes. All images will be more vibrant while still showing good detail in dark areas. The default Gamma setting of 2.2 is appropriate for most typical home theater environments.
Operation Runco CL-420 Owner’s Operating Manual 39 Color Temperature: To adjust the color temperature, select Color Temp from the Picture Adjust menu and press ENTER. (Color temperature defines the “color of gray.”) The range is from 5,000K to 10,000K, in increments of 500K. The default setting, 6,500K, is appropriate for most situations. Higher settings produce a “bluer” picture; lower ones impart a reddish hue to the image. For more precise control over the color temperature, you can adjust the x and y coordinates for gray. These define its location on the standard CIE chromaticity graph, shown in Figure 4-9. (CIE stands for “Commission Internationale de l’Éclairage” (International Commission on Illumination), the organization responsible for color measurement and management standards.) Changing either or both of these numbers changes the hue of gray, within a narrow range above or below the selected color temperature; refer to Table 4-2. To restore the default color temperature, select Reset Color Temp and press ENTER. Press ENTER again to confirm. Figure 4-9.

Operation 40 Runco CL-420 Owner’s Operating Manual ICC Select: Choose ICC Select from the Picture Adjust menu to specify the color space (Standard, NTSC, HDTV or PAL) that is appropriate for the source signal, to achieve optimal color balance. If you select NTSC, HDTV or PAL, you can make further adjustments to individual color space characteristics in the ICC Adjust sub-menu under the ISF Setting menu, described later in this section. (The Standard color space is factory-set and not adjustable.) White Balance: To remove any trace of color from the white areas of the projected image, choose White Balance from the Picture Adjust menu and press ENTER. •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. Save Settings: The CL-420 lets you save image quality settings for each input and supported resolution to a preset. You can recall this preset at a later time by simply pressing a button on the remote control or using the Restore Picture Settings menu command (see below). You should save changes to any of the following settings to a preset; otherwise they will be lost when a new input source or resolution is selected: Aspect ratio Picture adjustments (brightness, contrast, color saturation, tint, sharpness, gamma, color temperature, ICC selection and white balance settings) Image options (SDTV adjust settings, brightness enhance, lamp power) Restore Picture Settings: To recall a preset, choose Restore Picture Settings from the Picture Adjust menu and select “Custom1,” “ISF Day” or “ISF Night.” Or, use the corresponding buttons on the remote control. Image Option Use the controls in the Image Option menu to perform advanced image quality adjustments, obtain information about the projector or perform a factory reset. HD/RGB Adjust: To improve the quality of projected images from a computer or other analog RGB source, select HD/RGB Adjust and press ENTER. • Clock: If you notice flickering or vertical noise when displaying computer images, adjust the Clock setting to correct the issue. • Phase: Adjust the phase if the image shows shimmer or “horizontal” 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.) To restore the original Clock and Phase settings, select Reset and press ENTER, then press ENTER again to confirm the reset.
