I recently signed up for Prime HD, but notice a diminished HD quality and picture seems to "pixelate" or "tile" at during sports or action movies (all channels). Definately a step down from Dish.. Is there something I need to do, such as replace a coax cable or get a signal booster??
Anyone experience this?
I have never had tiling issues with FIOS. Had it all the time with cable which is why I switched.
If you didn't have the problem with Dish it is highly unlikely that your coax cables are the problem. And I doubt a signal booster would help. The FIOS signal should be just as strong as the Dish signal.
I recommend you call tech support. It sounds like a bad connection during installation.
