I have Dish TruHD, a 32inch LCD TV, with 720p picture resolution. I have two HDMI cables, one is a standard HDMI Cable, and one is a high speed HDMI cable, my Dish TruHD is currently connected with the standard HDMI cable. I was wondering whether connecting my Dish TruHD with the high speed cable will make a difference? And if it will, how significant a difference will it make?
