43 Basic OperationS4:3The size of the input signal iscompressed to 75% and projected.(This is useful for projecting apicture with a 4:3 aspect ratio onto a16:9 screen.)When a 4:3signal is beinginput[AUTO(S-VIDEO only)When an S1 video signal is input tothe S-VIDEO terminal, the aspectratio is changed automatically toproject a 16:9 picture.4:3The input signal is projected withoutchange.16:9The picture is compressed to a ratioof 16:9 and projected.When asqueezedsignal is beinginput. (Theprojectedimage iscontractedvertically)[quality will deteriorate, and the harder itwill become to achieve a good level offocus. To obtain the best picture quality,set up the projector and screen in sucha way that the amount of keystonecorrection required is as minimal aspossible.B The picture size will also changewhen correction of keystonedistortion is carried out.B The range of keystone correctionvaries depending on the type ofsignal being input. If you make anadjustment that is outside theallowable range, the setting will notbe changed. In addition, if the inputsignal changes after keystonecorrection has been carried out, thecorrection setting may be cancelled.This indicates that the currentcorrection setting exceeds theallowable range for the new inputsignal.B If you correct both vertical andhorizontal keystone distortion at thesame time, the allowable range ofkeystone correction becomessmaller. If you make an adjustmentthat is outside the allowable range,the setting will not be changed.OSD POSITIONPress the I or H buttons to movethe OSD position.ASPECTThis setting is only valid for an S-VIDEO/VIDEO signal and a YP BPRsignal in 525i (480i), 525p (480p)and 625i format.AUTO4:316:9S4:3
