My neighbor asked me to help her select and install a new TV. My experience is with DTV, she has Dish. It appears to be a simple configuration, replace the small existing TV with a new 40 – 48” flat screen. However, when Dish installed her system she wanted the receiver to be located on a wall where there was a network junction box and the TV on the opposite wall. I have not looked closely at the configuration yet but it appears there are 3 coax between the dish and the receiver then 1 coax from the receiver to the TV. Replacing the old TV will be simple enough but will she receive HD using coax between the receiver and TV instead of HDMI? Are TV manufacturers phasing out coax connectors? Thanks in advance for your help.
