Support XFINITY TV Add TVs to Your Location

Introduction

When you're adding TVs to your service, we don't recommend cable TV splitters.

Due to potential "noise" or interference, we require the installation of a data outlet instead of a cable splitter when adding a TV to your service. We may also need to adjust your main cable.

Schedule data outlet installation

To schedule the installation of a data outlet, contact us.
