Has anyone tried building a platform for a RPTV? I have a new Toshiba 55HX70, 55" HDTV and the height seems a bit low when seated about 13 feet away. I like the feeling of looking up slightly at the screen, sort of like what you get in a theater or front projection screen, rather than looking straight across. It seems to make the picture bigger and envelopes you more into the scene. Anyone tried this ?? Thanks.
