Bought this cable specifically to run between an HDTV (a 46" Samsung) and an upconverting DVD player (a Toshiba DVD recorder). After installation, the signal sent from the DVD player (a regular DVD upconverted to 1080P) was displaying static noise all over the place. Rechecked connections to make sure everything was plugged in correctly, but nothing helped. On a hunch, I set the DVD player to send a 1080i signal to the HDTV: no more static. Researching online, I found other people had the same problem with other cables from other companies: their problems were solved when they replaced their cheaper HDMI cables with more expensive ones. Since my HDTV also upconverts to 1080P, I ended up letting the DVD player upconvert only to 1080i, but this is not what I was expecting to do when purchasing this cable, and there is no reason why this cable should not be able to carry a 1080P signal.
