If you have an HD directv box then you should use an hdmi cable to connect it to the tv. IF you have a normal directv box check to see if it has component connections on the back (green, red, and blue). This would improve picture quality dramatically compared to coaxial.
I just bought this today and hooked my xbox up to it and it looks amaznig, but then when I put in on tv it looks terrible. I have satellite and my directv box is hooked up through the coaxial cable jack in the back, should I buy a composite cable and use that instead? Or is there just some settings I can change?
