I have an Ott Tv Box and trying to hook it to an older Mitsubishi CRT 65" HDTV... it has a DVI port on the tv and I have an HDMI cable that connects to it (HDMI one side, DVI other) however, I can't seem to get the resolution right. The HDMI to DVI works just fine with HDTV tuner and DVD player. I was able to hook the tv box up to my computer LED screen in order to unselect automatic resolution... as hooking it to the tv prior gave an unusable signal.... When I select the 1080i 60Hz (DVI port only allows 1080i, 480i and 480p), the screen looks bad... 50Hz selection does not work. With 60Hz, I get some flickering horizontal lines every few inches and just not easily readable.... 480p seems to distort color a bit but no flickering lines soooo 480i looks about best but I'd really like to use my 1080 resolution! What gives?
