20 TEST SCREENTest ScreenTest ScreenWhen you press the TEST button on the frontpanel or on the remote you can activate a stillimage to test all settings and the video perform-ance of your TV. With the vertical color bars youcan 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 sharp separa-tion of the bars, S-Video will be better thanVideo, 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 been final-ized. They can also be made at any time whenthe player is in Stop or Resume mode, simply bypressing TEST on the remote control or on thefront panel.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 lot there-by.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 for optimisa-tion.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, depend-ing from the TV used some of the bars willseem 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 a dif-ference in preference as how the glow of thepicture should be. Some prefer a little colderpicture, some a warmer glow. The Tint functionon your TV and the white bar can be used tocontrol this. Adjust the Tint to the level whereyou feel the white color has the tone youprefer.Color BarsGrey Scale100%Black/Whitefields
