TV Pixelation

@XfinityDuron​ Still getting pixelation on HD live programs on Popular TV cable channels, but not when streaming on my TV, HD programs on apps like Prime Video. 

You have tried exchanging boxes and or HD cords if they are being used? @user_grqspw

On March 4, I exchanged an old X1 TV Box for a new one at an Xfinity store and spent 45 minutes on the phone with an Xfinity tech the same day.  I also replaced the HDMI cable with a new one that came with the old X1 TV Box but had not been used yet.  It did not solve the pixelation problem.  If it makes any difference, I do not have a smart TV nor a 4k TV.  Are there different types of HDMI cables?  If so, maybe I do not have the most up-to-date version???

I will be more than happy to help with your request. To begin, would you mind sending me your name and the address to your account in a Direct message?
