The InFocus X-1 and NEC LT-240/60 are among the recent well-reviewed and well-regarded 4:3 projectors which have a 16:9 "mode." Unfortunately, neither owners manual explains exactly what the projector is "doing" when you select this mode. Is the X-1 simply cropping 75 rows of pixels from the top and bottom of the image and then scaling the input signal to the remaining 450 lines? Is the NEC doing the same thing but with 96 rows off the top and bottom? Could someone who actually knows please enlighten me?
