Re the HS50, I've read: "When HDTV or Computer signals are displayed, no aspect ratio choices are available. All HDTV is 16:9 aspect ratio, so this is done to simplify use and prevent improper user choices. Some computer users will complain about the lack of flexibility and wish that aspect ratio choices were allowed in computer modes." The statement is slightly ambiguous, so my question is, can this pj project a 4:3 computer image without distorting it to 16:9? I want black sidebars! Having been wooed by DLP contrast, but underwhelmed by talk of rainbows, a theoretical contrast ratio of 6000:1 in an LCD has to be worth thinking about. I just need accurate computer display just as much as I need cinema input.
