Gentlemen: I have been laboring under the delusion that I was receiving a digital signal for my TV through Spectrum(formerly Time Warner). I got rid of a newer tube type TV in the bedroom and replaced it with a 42" LEDTV. When I turned it on after setup my picture was not real sharp and thought I had a problem with the TV or cable connections. Ruled that out when accessing Netflix on my WIFI, TV was sharp as a tack. Cleaned cable connections to the TV, no joy. Called cable co. and was informed cable was analog and only going through cable co. box could I get digital signal to TV ($5./mo.). Is there some kind of item that I can purchase 1 time to get the digital signal to this tv and avoid a monthly rental fee?
