Quick question:

If HDMI and DVI are strictly digital signals (00110100111101101), is there any benifit to going with a more expensive cable? I fully believe that cables make a world of difference and that you do need good shielding on any analog signal - but digital? Seems kinda like a gold plated USB cable - really no use at all.

Also, what is the signal drop off length for an HDMI cable?
