Whenwide-screen signals 3 are input, they areconverted by the PT-D5600U to the 4:3aspect ratio and displayed. With the PT-DW5000U, the images are reduced insize and displayed without convertingtheir aspect ratio so that they will fit ontoa screen with a 4:3 aspect ratio.S4:3 : Select this setting when using a 16:9screen.HV FIT : At this setting, the images are displayedto fill the entire screen.If the aspect ratios of the input signalsand screen differ, the images areconverted into the screen’s aspect ratio(4:3 for the PT-D5600U or 15:9 for thePT-DW5000U) and displayed.1 S1 video signals are 16:9 video signals towhich is added the detection signal output fromthe video deck or other unit which supports thewide-screen format.2 Here, the standard signal means 4:3 or 5:4input signals.3 Here, the wide-screen signals means 16:9,15:9 or 15:10 input signals.Adjusting the pictureAIGray scale control is exercised to suit the images,and optimal images with a clear contrast areprojected.ON : AI compensation is enabled.OFF : AI compensation is disabled.TV-SYSTEM(For S-Video/Video signals)The setting that corresponds to the TV system isselected here.AUTO1 : Standard settingAutomatically selects the TV standardthat matches the input video signal, outof NTSC, PAL, NTSC4.43, SECAM andPAL60.AUTO2 : Automatically selects the TV standardthat matches the input video signal, outof NTSC, PAL-M, and PAL-N.• Normally “AUTO1” or “AUTO2” should bechosen for this option.• If the video signals are not displayed properlydue to signal deterioration, choose the TVsystem that matches the input video signals.Automatically selected by detecting thehorizontal/vertical scan frequencies and color sub-carrier listed in the table below:SYSTEM(For RGB/YP B PR signals)This enables the RGB system or YP B PR system tobe selected.For the signals which are supported, refer to page58.SignalSystemNTSCNTSC4.43PALPAL-MPAL-NSECAMPLA60H.
