20 TEST SCREENTest ScreenTest ScreenWhen you activate the Test Screen via the OSDyou can activate a still image to test all settingsand the video performance of your TV. With thevertical color bars you can test the following:■ proper color intensity setting on your TV,■ the proper color of each bar, showing if theproper video standard is turned on: the colorsshould be (left to right): black, white, yellow,cyan (turquoise), green, magenta (purple), red,blue, black.■ proper color transition, seen as sharpseparation of the bars, S-Video will be betterthan Video, RGB best of all.■ the performance of the color filter in your TV(with ”Video” signals), bar edges should showno vertical crawling dots. Here S-Video andRGB formats usually give no problems.With the grey scale and the black/white fieldsbelow the color bars the brightness and contrastof your screen can be adjusted optimally, seechapter ”TV Picture Adjustment” below.TV Picture Adjustment withTest ScreenThese adjustments may be done now, but youcan also make them after setup has beenfinalized.Brightness adjustment:1. Turn down the color control on your TV untilthe color bars are visible in black and white.2. Adjust the contrast to the lowest level whereyou still can see all bars within the grey scalein the test picture separately and clearly.3. Adjust the Brightness so that the bars in thegrey scale are all visible. The bar furtherst tothe left has to be as black as possible ratherthan grey but the next aside must clearly bedifferable. All the bars in the grey scale have tobe gradually and evenly changing from blackto whiter, going from left to right.Contrast adjustment:1. Adjust the contrast on your TV until you see abright white bar in the right low corner of thescreen and a deep dark black bar at the left.The optimal contrast setting will depend fromyour preference and the surrounding light inthe TV room.2. If the brightness of the white bar will no moreincrease while turning up the contrast or whenthe borders of the white ”harman/kardon” textletters on top will bloom (overlight) into theblack areas, what drasticly will decrease thesharpness of the script, then the Contrast hasbeen turned up too much. Reduce the contrastuntil these effects will disappear and the videostill looks realistic.3. If you are watching TV with a usual surround-ing daylight, adjust the Contrast so that a nor-mal video picture has about the same lookingas the surroundings in your room. By that waythe eye is relazed when watching the TV pic-ture. This contrast setting may be reducedwhen the surrounding light is dimmed, usuallyimproving the sharpness of a video a lotthereby.4. The grey scale in the middle line needs to havethe same clear difference between each bar asbefore the contrast adjustment. If not, go backto the brightness adjustment and repeat step 3and then the contrast adjustments, makingonly minor adjustments each time foroptimisation.Color adjustment.1. When the Brightness and the Contrast are setoptimally, turn up the color control to the levelof your perference. Adjust to the level wherethe colors look strong but still natural, notoverdone. If the color level is too high,depending from the TV used some of the barswill seem wider or the color intensity will notincrease while the control is turned up. Thenthe color control must be reduced again. At theend you should test the color intensity alsowith a video, e.g. pictures of natural faces,flowers, fruit and vegetables and other wellknown natural articles of our life most usefullfor an optimal setting of the color intensity.2. If your TV has a Tint option (with mostEuropean TVs this is available or effective onlywith NTSC signals, not with PAL), use the largewhite bar below the Greyscale to tweak thewarmth of the picture. Every viewer has adifference in preference as how the glow ofthe picture should be. Some prefer a littlecolder picture, some a warmer glow. The Tintfunction on your TV and the white bar can beused to control this. Adjust the Tint to the levelwhere you feel the white color has the toneyou prefer.Color BarsGrey Scale100%Black/WhitefieldsSharpness AdjustmentContrary to intuition, the picture will appearsharper and clearer with the sharpness, or Edges,setting backed off from the maximum setting.Reduce the sharpness setting on your television,and the Edges setting on the DVD 29 videoadjustments menu if necessary, to minimize theappearance of any white lines between the barsin the gray scale portion of the test screen.Convergence and Edge FocusThe crosshatch pattern that surrounds the testscreen may be used to evaluate edge focus andconvergence in front- or rear-projection videodisplays. However, the controls used to adjustthese parameters are often not user-accessible.In any event, these adjustments are extremelycomplex, and require proper training andexperience to avoid worsening the situation.Therefore, it is recommended that if you areunable to improve the picture using the availablecontrols, contact the video display manufacturer’sauthorized service representative for assistance.When all desired setup and configuration entrieshave been made, use the KL NavigationButtons 9 until “Done” is highlighted at thebottom of the Video Adjustments submenu. Pressthe Enter Button 6 to select it to return tothe on-screen menu system. Then, press theSetup Button 8 to remove the menu displaysfrom the screen. The unit will return to normaloperation and you are ready to enjoy the finest inDVD or CD playback!
