41 Basic OperationNOTE:• S1 video signalsS1 video signals are a type of videosignal with an aspect ratio of 16:9which include a detector signal. Thisdetector signal is output by somesources such as wide-vision videodecks. If the AUTO setting above isselected, this projector will recognizethe detector signal and automaticallyswitch the aspect ratio to 16:9 in orderto project the picture.• This projector is equipped with anaspect ratio selection function.However, if a mode which doesnot match the aspect ratio of theinput signal is selected, it mayaffect the quality of viewing of theoriginal picture. Keep this in mindwhen selecting the aspect ratio.• If using this projector in placessuch as cafes or hotels with theaim of displaying programs forviewing for a commercial purposeor for public presentation, notethat if the aspect ratio (16:9)selection function is used tochange the aspect ratio of thescreen picture, you may beinfringing the rights of the originalcopyright owner for that programunder copyright protection laws.• If a normal (4:3) picture which wasnot originally intended for wide-screen viewing is projected onto awide screen, distortion may occuraround the edges of the picture sothat part of the picture is no longervisible. Such programs should beviewed in 4:3 mode to give properconsideration to the aims andintentions of the original program’screator.RESIZINGThis should normally be set to “ON”.(This setting is only for signalswhich have lower resolutions thanthe LCD panels. Refer to page 60for details.)ONThe pixel resolution of the inputsignal is converted to the sameresolution as the LCD panels beforebeing projected. For signals withlower resolutions, gaps in the pixelsare automatically interpolated intothe picture before it is projected.This may sometimes causeproblems with the quality of thepicture.OFFThe picture signal is projected at itsoriginal resolution, with no pixelconversion. The projected picturewill be smaller than normal, soadjust the zoom setting or move theprojector forwards or backwards toadjust the picture size if necessary.If set to “OFF”, some features, suchas D.ZOOM (digital zoom) orkeystone distortion correction willnot function.AUTO SETUPThis item functions in the same wayas the AUTO SETUP button on theremote control unit. (page 15)FRAME LOCKIf the picture’s condition is bad whilea RGB moving picture signal isprojected, set the FRAME LOCK to“ON”. Refer to page 60 oncompatible RGB signals.
