I have two separate TVs that have poor (but not totally unwatchable) picture quality but are crystal clear when using a streaming services via Roku/Amazon Fire Stick. I am not sure if it is related to possibly older equipment (set top boxes or Actiontec MI424WR router) or the fact that our main box is in the basement and splits (PDI-2WMS-5 5-1000 MHz) twice before reaching the basement TV or router. Maybe it is something else entirely but it is very annoying considering how much it costs. Any help is appreciated.
