I have Xfinity cable with the X1 Platform and have an LG TV. I got the TV about 3-4 years ago. It seems when I watch NFL Redzone the screen goes pixelated a lot. This doesn't happen with any other channel besides this one. My wires and and connections are great I'm not sure what else I can do. Please help TIA!
Channels come in on different frequencies, that's why one channel could be affected and not others. You probably should get a tech out to troubleshoot further to see the cause.
You can also check how your cable outlets are configured, any amp or splitters. Your dvr is a little out of spec as is your modem.
Your new cable-box should be connected to the television using a newer high-speed HDMI cable.
Check your coaxial cable from house outlet to your cable-box. Check for both tight connections and good connection of cable to cable connector on each end of the cable. If wiggling the coaxial cable near either end of the cable causes picture problems you need a new cable. Are you still using an older HDMI cable?
I'm using a brand new HDMI cable that came with the X1 box they gave me a few weeks ago.
Unfortunately, the Comcast HDMI does not support 4k. That may not make a difference since the X1 box is not capable of sending a 4k signal.
But if I were you (I'm just a user) I would TRY a 4k HDMI cable.
The problem may be between cable terminal box and the cable coming into your house (Comcast problem),
Were you able to check this first inside location? Do you have a cable splitter used before connecting to this cable-box? Is this the only television being used on cable tv?
