Connected converter to my small (14") LCD TV (resolution 640x480) and had a great picture immediately. Text is blurry, but if you want to watch dvd, downloaded movies, or one of the streaming networks (like HULU) on your TV using the component video inputs, it's great. from Amazon.com I'll bet the three complainers didn't pay attention to the RANGE....30 meters!!! I had this across the house and had the same problem...moved to a PC that was in the next room and the picture (and SOUND!) was perfect. from Amazon.com The picture quality was poor. Poor brightness-contrast. from Amazon.com This unit is junk! In my application, I have a video card with an S video output and a TV with S video as well as hi def component inputs. from Amazon.com Excellent product. Very good alternative to installing expensive video cards. from Buy.com
