I bought a Sharp LC32-LE600 LED-TV as replacement for the old 19" CRT which I've been using since ten years. Now, the manual says, that my 1920x1080 Full-HD TV is capped at 1360x768 when connected to a PC. Now I am totally stumped, because I didn't knew that. Not even the datasheet from the original manufacturer, sharp.com told one word, that PC-input can't display 1080. I'm unsure if I should give this LED-TV back, are they all limited to 768p when connected to a PC?
