We were told that the max length of the DVI cable is 25'. In our showroom we mounted the switcher/scaler with the 6' cables in the basement below the screen and ran 12'component cables to it. The picture is a little grainy and I don't know if this is due to the cable length or not. I suspect that at 12' it is not the cables fault but I have seen great reports on the picture quality of the Pioneer in this forum. Has anyone else noticed grainy plasmas from Pioneer?
