Ordered and installed four Digital Transport Adapters for our TV's, two LCD's and two CRT's. The picture quality after installation on the LCD's is noticably worse than before the install. The LCD pictures appear to be no better than analog. We had much better pix on the LCD's before the transition; some visitors said near-HD quality. A Comcast rep confirmed on the phone my understanding that the transition is to implement a pure wall-to-wall digital signal all the way to the customer's TV, but it would require installation of the new equipment. So, after all of this, I get an ANALOG picture on my LCD's? Added channels are nice, but at the expense of picture quality? Is the next step having a technician come take a look? Or are others experiencing the same thing? What am I missing here?
Thanks for the helpful comment. Your comment was much clearer than Comcast's letter to me: "You should check each TV in your home to see if it's connected to to a digital set-top box, digital adapter, or CableCard device (like a Tivo)". They didn't make any distinction between LCD and non-digital TV's.
The Free dta boxes convert the digital signal to analog thats why your picture is bad. You should not put a DTA box on an lcd tv if you want a good picture, the DTA boxes are meant for two scenarios only.
1. You have an old tube type tv that cannot get digital.
2. You can't afford or don't want a digital box and still want to receive cable.
The DTA boxes are not meant for newer type tv's as they are just converting the digital signal to anolog, so you need to rent a ditial box if you want good looking tv, if those lcd's are HD you need to rent an HD box to see HD.
