I am considering an LCD TV and I have a question regarding the aspect ratio. A 23" (16X9)diagonal Sony, for example, when being fed a tv signal in 4X3 mode, I guess it will have the dark bars in the sides. Can the aspect ratio be changed to 16X9 with a proportioned image, i.e. not vertically shrinked? I am more interested in TV viewing, for this LCD TV, so maybe I would be better with a 20" diagonal 4X3 unit, I guess, if the TV viewing requires the bars in the sides, I will have a bigger 4x3 picture. I have been diconnected from this forum for a while, so I don't know how are these things lately. thanks.
