Digital is digital is digital.
It doesn't matter at all. With digital signals, it either goes through or doesn't. There is no such things as a difference in quality. Say you use a $0.50 HDMI cable, if the picture is showing, you're already getting all the quality you're going to get. Paying more for a cable is just for the fit and finish or look, there will be zero performance difference.
Analog signals on the other hand (VGA, for example) can benefit from a better cable if your cable runs are long or there is a lot of possible interference around.
