I'm finally taking the plunge and upgrading to HD Dish. I've got the HD TV's already which have HDMI inputs but they receive the TV signal right now through coaxial inputs from the old Dish boxes which are in the basement. I have each Dish box going to 2 TVs. I would like to connect the new boxes in the same manner. They will be connected to the TV's with HDMI cables and I will probably move the box to a location closer to one of the 2 TVs. The question I have is will I be able to split the output from the new box to feed video to 2 TVs? I'd like to be able to have the 2 sets on at the same time, obviously they will be tuned to the same channel, but simultaneous viewing would be nice.
Along with the splitting, what would be maximum cable length be to transmit HD television channels? I would hopefully be able to put the boxes in a central enough location that I won't exceed 50ft spans per box, but will that work? And even better, is it possible to use the 100ft HDMI cables on monoprice with Dish boxes?
