Most porthole sets feature a switch to change the aspect ratio (i.e. stretch the vertical). As a kid looking at old magazine ads for Zeniths, I always wondered just how the picture would look on a porthole screen. I found out about the switch the first time I saw one of these sets actually operating at an old repairman's shop. The upper and lower portions of the screen were black while a picture of normal proportion filled the width of the screen. When I asked him why he didn't make the raster fill the screen, he told me about the switch, mumbling something about "distortion." So does anybody watch their porthole set with the switch in the "normal" position?
