My new cable box used the same RG6 or RG59/U cables so if you used that, then you only need to replace the decoder box and viola.
I'm surprise your provider didn't answer that.
About the speakers though. Tough break. I would not call such good even in a high end TV. Example follows at link.
Not a word on the speakers.
I want to buy my first flat screen TV, but the standard TV cable was cemented into the slab (about 5 years ago), under the flooring, and cannot be changed.
Can I buy a non-HD TV somewhere? I'm looking for a 40"-42" LCD/LED set with good speakers (no home audio system for me), 1080 resolution, and really good picture quality. I don't want all the smart features, internet capability,3-D, gaming, etc.
What's my best bet?
