i have been able to shift the vertical position on other sets i have owned and this minimized the noise without having a black bar on the bottom so why should this set be any different.
You're correct in the fact that Stretch does zoom the picture in a bit. However, like I mentioned previously, if you're watching HD satellite/cable/Uverse/FiOS, there is
no way you're getting effective 1080x1920 picture resolution. No broadcast source measures detail that high. That might be the format (1080i), but not the effective resolution. Probably closer to 900x1600. The picture may look a bit sharper on dot-by-dot, you're not losing resolution.
If you're using Dot-by-Dot on another 1080p set and shift the picture up even a few pixels, there's no way to
not have a black/blank area on the bottom of the image, when you have a 1080i source. If you shift the top 2% off of the picture, where does the bottom picture information come from?
