53Cross Color Suppressor: Turn this setting on to remove cross colorartifacts, which can occur when high-frequency luminance (brightness)signals are misinterpreted as chroma (color) signals, which can causeunwanted flickering, flashing colors or rainbow patterns.Film Mode Detect: While normally left off, turn this setting on to com-pensate for authoring errors in the process of converting film programsto video.How to Adjust the Custom Picture SettingsSet the Video Mode to Custom to display the picture settings as shownin Figure 73.Figure 73 – Video Modes Custom ProcessingWith a color bar test pattern screen from a test disc or other sourceshowing on your video display, the following adjustments may be made:• The proper color intensity setting on your TV.• Proper color adjustments using the color bars, which should be (leftto right) black, white, yellow, cyan (turquoise), green, magenta, red,blue, black.• The proper color transition, seen as sharp separation of the bars.• The performance of the color circuits in your TV (with “Video” signals);bar edges should show no vertical crawling dots.With the gray scale and the black/white fields below the color bars, thebrightness and contrast of your screen can be adjusted.Brightness Adjustment1. Turn down the color control on your TV until the color bars appearin black and white.2. Adjust the contrast to the lowest level where you still can see all grayscale bars separately and clearly.3. Adjust the brightness so that the bars in the gray scale are all visible.The bar farthest to the left has to be as black as possible rather thangray but the next gradation must clearly be distinct from it. All thebars in the gray scale should be gradually and evenly changing fromblack to white, left to right.Contrast Adjustment1. Adjust the contrast on your TV until you see a bright white bar in thelower right corner of the screen and a deep-dark-black bar to theleft. The optimal contrast setting will depend on your preference andthe surrounding light in the TV room.2. If the brightness of the white bar no longer increases when the con-trast is turned up or the borders of white letters bloom (overlight) intothe black areas (drastically decreasing the sharpness of the type), thecontrast has been turned up too much. Reduce the contrast untilthese effects disappear and the video still looks realistic.3. If you are watching TV with ambient daylight, adjust the contrast sothat a normal video picture has about the same look as the surround-ings in your room. That way the eye is relaxed when watching theTV picture. This contrast setting may be reduced when the surround-ing light is dimmed, thereby usually improving the sharpness of avideo significantly.4. The gray scale in the middle line needs to have the same cleardifference between each bar as before the contrast adjustment. Ifnot, go back to “Brightness Adjustment” and repeat Step 3 and then“Contrast Adjustment,” making only minor adjustments each time foroptimization.Color Adjustment1. When the brightness and contrast are set optimally, adjust the colorcontrol to the level of your preference. Set the level so that the colorslook strong but still natural, not overdone. If the color level is toohigh, depending on the TV, some of the bars will seem wider or thecolor intensity will not increase when the control is turned up. Thenthe color control must be reduced again. Ultimately, you also shouldtest the color intensity with a video – e.g., pictures of natural faces,flowers, fruit and vegetables, and other common natural articles foran optimal setting of the color intensity.2. Refer to the large white bar below the gray scale to tweak thewarmth of the picture. Every viewer has a preference as to how theglow of the picture should be. Some prefer a colder picture, somea warmer glow. The Tint function on your TV and the white bar canbe used to control this. Adjust the Tint to the level where you feelthe white color has the tone you prefer.Sharpness AdjustmentContrary to intuition, the picture will appear sharper and clearer with thesharpness backed off from the maximum setting. Reduce the sharpnesssetting on your television, and the setting on the AVR 354 if necessary,to minimize the appearance of any white lines between the bars in thegray scale portion of the test screen.Convergence and Edge FocusThe crosshatch pattern that surrounds the test screen may be used toevaluate edge focus and convergence in front- or rear-projection videodisplays. However, the controls used to adjust these parameters areoften not user-accessible. In any event, these adjustments are extremelycomplex, and require proper training and experience to avoid worseningthe situation. Therefore, it is recommended that if you are unable toimprove the picture using the available controls, contact the video displaymanufacturer’s authorized service representative for assistance.When you have finished making any video adjustments, press theBack/Exit Button to back out of the menu system.ADVANCED FUNCTIONS
