TEST SCREENTEST SCREEN 22DVD is one of the highest quality sources ever madeavailable for in-home playback of prerecorded picturesand sound. In order to make certain that your hometheater system is fully optimized to take advantage ofDVD’s superb picture quality, the DVD 27 offers abuilt-in video test signal that makes it easy to calibrateyour TV or video display for proper playback.Test ScreenWith the test screen showing on your video display, thefollowing adjustments may be made:• The proper color intensity setting on your TV.• Proper color adjustments using the color bars, whichshould be (left to right) black, white, yellow, cyan(turquoise), green, magenta, red, blue, black.• The proper color transition, seen as sharpseparation of the bars.• The performance of the color circuits in your TV(with “Video” signals); bar edges should showno vertical crawling dots.With the gray scale and the black/white fields belowthe color bars, the brightness and contrast of yourscreen can be adjusted.NOTE: Most of the video adjustments using theDVD 27’s test screen should be made using thecontrols on your video display, with the DVD 27’scontrols set at their factory default position in thecenter. If necessary, you may tweak the brightnessand sharpness using the controls found in theDVD 27’s video adjustments menu.Figure 9TV Picture Adjustment With Test ScreenBrightness Adjustment:1. Turn down the color control on your TV until thecolor bars are visible in black and white.2. Adjust the contrast on your TV to the lowest levelwhere you still can see all bars within the gray scalein the test picture separately and clearly.3. Adjust the brightness using the DVD 27 videoadjustments control so that the bars in the grayscale are all visible. The bar furthest to the left hasto be as black as possible rather than gray, but thenext gradation must clearly be distinct from it.All the bars in the gray scale should be graduallyand evenly changing from black to white, goingfrom left to right.Contrast Adjustment:1. Adjust the contrast on your TV until you see a brightwhite bar in the lower right corner of the screenand a deep-dark-black bar to the left. The optimalcontrast setting will depend on your preference andthe surrounding light in the TV room.2. If the brightness of the white bar no longer increaseswhen the contrast is turned up or the borders of thewhite “harman/kardon” letters on top bloom (over-light) into the black areas (drastically decreasingthe sharpness of the type), the contrast has beenturned up too much. Reduce the contrast untilthese effects disappear and the video still looksrealistic.3. If you are watching TV with customary surroundingdaylight, adjust the contrast so that a normal videopicture has about the same look as the surround-ings in your room. That way the eye is relaxedwhen watching the TV picture. This contrast settingmay be reduced when the surrounding light isdimmed, thereby usually improving the sharpnessof a video significantly.4. The gray scale in the middle line needs to havethe same clear difference between each bar asbefore the contrast adjustment. If not, go back to“Brightness Adjustment” and repeat Step 3 andthen “Contrast Adjustment,” making only minoradjustments each time for optimization.Color Adjustment1. When the brightness and contrast are set optimally,turn up the color control to the level of your prefer-ence. Adjust to the level where the colors lookstrong but still natural, not overdone. If the colorlevel is too high, depending on the TV, some of thebars will seem wider or the color intensity will notincrease while the control is turned up. Then thecolor control must be reduced again. Ultimately, youalso should test the color intensity with a video –e.g., pictures of natural faces, flowers, fruit and veg-etables, and other common natural articles for anoptimal setting of the color intensity.2. Use the large white bar below the gray scale totweak the warmth of the picture. Every viewer has apreference as to how the glow of the picture shouldbe. Some prefer a little colder picture, some awarmer glow. The Tint function on your TV and thewhite bar can be used to control this. Adjust the Tintto the level where you feel the white color has thetone you prefer.Sharpness AdjustmentContrary to intuition, the picture will appear sharperand clearer with the sharpness, or Edges, settingbacked off from the maximum setting. Reduce thesharpness setting on your television, and the Edgessetting on the DVD 27 video adjustments menu if nec-essary, to minimize the appearance of any white linesbetween the bars in the gray scale portion of the testscreen.Convergence and Edge FocusThe crosshatch pattern that surrounds the test screenmay be used to evaluate edge focus and convergencein front- or rear-projection video displays. However, thecontrols used to adjust these parameters are often notuser-accessible. In any event, these adjustments areextremely complex, and require proper training andexperience to avoid worsening the situation. Therefore,it is recommended that if you are unable to improvethe picture using the available controls, contact thevideo display manufacturer’s authorized service repre-sentative for assistance.When all desired setup and configuration entries havebeen made, use the ⁄¤ Navigation Buttons nuntil “Done” is highlighted at the bottom of the VideoAdjustments submenu. Press the Enter Button sto select it to return to the on-screen menu system.Then, press the Setup Button j to remove themenu displays from the screen. The unit will return tonormal operation and you are ready to enjoy the finestin DVD or CD playback!Color BarsGray Scale100%Black/WhiteFields
