I am using a Roku streaming stick with an LG TV (model 50PQ30).
My image displays correctly with other devices, but through the Roku (with Netflix app) the image is stretched vertically off the screen, so the top of the image and the bottom doesn't show. You can still watch Ok, though subtitles and sometimes the progress bar (showing how much video is left) is off the bottom and therefore not visible. Also, the people look odd when stretched a little too.
My resolution is just autodetected at 1080p, I have tried a couple of other settings but it changes nothing.
