    Xbox One losing TV signal - Comcast Xfinity X1

    I keep losing my TV Signal with the Comcast Xfinity X1 cable box. I have set the cable box to 720p, tried multiple HDMI Cables, and disabled the screensaver. I can get picture but when I do lose signal I have to go through the settings again to regain
    the picture.

    Anyone have any luck with the Xfinity X1 system? If so can you tell me what settings you used when walking through the wizard for live tv setup as I don't believe the X1 is there by default.

    Thanks

    X1 Platform/Xbox One Set Up

    I have the X1 Comcast DVR box too. Trying to set it up with XBOX ONE. The HDMI Out from the comcast box is going into the HDMI IN for XBOX ONE. I see no signal. Comcast confirms me that they are able to ping the box and signal is fine. Am I missing a setting
    that I have to do in XBOX ONE to make it working? Asking for help?

    Trouble with Xbox One Guide

    Set up Comcast box manually. Type in Xfinity instead and see that gives you more choices. I have a x1 box from Comcast, could not find it until I typed Xfinity.

    X1 Xfinity cable box not able to change channels

    Hi Swanlee,

    Try setting make=Comcast (or xfinity), model=X1. That should work.

    hdmi splitter/cable box/TV/Xbox One

    Curious to hear if the SithLordBlack was successful. Bought a SSIG 1x2 HDMI Ampified Splitter and both TV and Xbox One could not get signal. Checked HDMI cables and they all work if Xfinity X1 device is hooked directly to Xbox One but didn't work through
    splitter. In fact, couldn't even get signal on TV so neither split worked. Spent $90 on it at MicroCenter so it's going back. Saw a Rocketfish Splitter at Best Buy I may try next. Please let me know if you have had success splitting the signal. Trying
    to split Comcast signal so wifey can watch TV normally through AVR or I can watch football though Xbox One with the NFL App.

    Comcast X1 and Xbox One trouble

    I am having the same trouble using the standard X1 box. During setup - I've tried selecting Comcast or Xfinity (no Comcast X1 option available) and the Channel up / Down features don't work. I can continue forth however when watching TV I can't use the
    pause / ffwd functions, nor can I select a channel to watch from the OneGuide. Any Ideas? My Kinect is sitting on top of the cable box...not sure if this contributes to that issue?
