I think the cable is the correct one, otherwise, you wouldn't have gotten anything. As for the black fuzz (I just can't picture it in my head what you are talking about).
I have a Samsung upconverter, using a dvi cable with an adapter; and the only time I have video is when the resolution is set at 480p. I suspect my tv just cannot handle 720 or 1080. I consult the manual (but nothing!). Anyway, a little more experimentation is needed, hehe.
i have a sony 70 series upscale dvd player and a 52in rca tv from walmart- i got a dish network cable that has hdmi connection on one side and dvi connection on the other , i hear about a hdmi-dvi adapter and was wondering if this cable is the proper cable to use here. my picture is no better than the regular dvd i had. i set it on all resolution settings and notice no difference between them. my picture has like a black fuzz in the background anyone know how to fix this???????????
