X1 and new 4K tv

we upgraded out tv to a basic  4K tv to get a better picture quality with the X1 cable box. The picture quality is terrible. YouTube has a better picture quality when streaming to the tv.  The setting is set for 1080 16:9 and I still see a black bar top and bottom. The picture quality is not even HD.  We have basic expanded service. Is anyone else having issues with picture quality? Do I need a different cable box for the Tv? It's hooked up via HDMI from the box to the TV. Any help would be appreciated to get a better picture on the new tv.

Hi @Ervtoth , thank you for reaching out to us here on our forums. I can help you with  your aspect ratio which is causing the screen to look the way it does. Do you have your Xfinity remote near you. Try these steps below. 

 

  1. Press the xfinity button on the remote.
  2. Select HDMI Setup, then press OK.
  3. Select TV Output Resolution. Depending on your TV, not all options will be available.
    • To use the recommended output setting, select Auto.
    • For an SD TV, select 480i.
    • For an HD TV, select 1080i or 720p.
    • Select Apply within 10 seconds.
    • If you lose the picture, the resolution will automatically go back to the last setting in 10 seconds.
  4. Next, select the TV Aspect Ratio. If 1080i or 720p is being used, only the 16:9 option will be available.
    • To use the recommended aspect ratio setting, select Auto.
    • For a square-shaped TV, select 4:3.
    • For a rectangular-shaped, widescreen TV, select 16:9.
  5. press exit on the remote

@ComcastAshley We have tried all these settings and had multiple signal tests sent to the tv from chat and phone calls with no luck.  I now have to pay $59 to have a service technician come out on Saturday to look at this issue. I think there is a problem with the line, not the TV and X1 box. The picture quality on the old tv and new tv is the same. The old tv was a 1080 hooked up to a digital antenna and had a better picture than what I am getting now.

adding... except for a cathode ray picture tube (old analog) use 1080p never 1080i as the conversion process destroys the picture data and forces the flat panel digital display panels to convert back to 'p' (progressive).
