I am planning on upgrading my lcd tv (about 5 years old) to a more upscale hd one. I'm doing a "self-install" fios tv (I have had fios internet and phone for close to a year). From an old Time Warner cable installation, there is existing RG59 cable, which I'[m using as a conduit for the wiring to stb. This gives acceptable tv viewing. But when I upgrade my tv, will the RG59 cable give me good hd? Should I be using RG6 instead?
