Thanks, guys. I'm just trying to pick the collective brain - I know there's a lot of clever and resourceful people here. My TV is good to go with coax, but the results are less than stellar. Rather than explore some form of improvement on my TV coax, I figured there might be some adapter + freeware solution out there to add to the spectrum of options. I run my primary TV input off a PC, so I figure that an HDMI solution seems reasonable in 2018 - ?
