I spent over an hour with samsung on the phone and the remoted into the tv and after testing, they determined that it is a comcast issue. Apparently I have the X1 digital platform. It works fine but if i go into the setting and turn HDMI UHD Color on, it restarts the TV, then i get this incredible picture with no sound. It works when i use the smart functions, apps, etc. but not with regular channels. Also, to answer the other question below yours, I am using a 3D & 4K Ultra HD high speed HDMI cable. Is there a better box that is offered? It is really frustrating looking at this beautiful picture with no sound. What do you suggest?
other than a samsung app that puts out UHD comcast is not offering UHD at this time. the x1 boxes do not put out higher than 1080i/p
