Xfinity X1 Cable Boxes Conflicting With 4K UHD Players

Let me try to explain this as best as I can.

 

Recently, I purchased my first 4K UHD Blu-ray player, connected it directly to my 4K Vizio Smart TV. I have 3 HDMI ports on my TV, I have my XBOX One connected to one port, my Xfinity cable box connected to the second port and my Sony 4K player connected to the third port. None of these are connected to the cable box. Unfortunately, when I try to switch over to watch my Comcast channels, sometimes I get weird connection problems where the video looks like its shorting out, soometimes the audio wigs out. This would happen several times a day. Then, something occurred to me and I unplugged my HDMI cable from my 4K TV and the errors stopped happening.

 

There is something with Comcast's cable boxes that is conflicting with 4K players. I'd like to know if Comcast has fixed this conflict, because it appears to be a hardware conflict between 4K UHD players and the cable box. I never have this problem with my XBOX One or my previous standard Blu-ray player.

 

I'm at a loss and looking for some answers.

Well, I was able to figure it out with some help from some techies over on the Blu-ray.com forums. Plug and Play should have corrected the issue but it didn't. Had to go into the setting and ensure that the HDMI ports were properly configured for the new 4K device.

What device did you unplug the hdmi from? Have you tried a different hdmi port? Change hdmi cord? Swap the box out?

I unplugged the HDMI cable from my Sony 4K player. I've also tried changing the HDMi cables for each device and switched which cables are plugged into which ports. The Vizio 4K TV I purchased about 18 months ago so it's fairly new. It's a 55" 4K Smart TV.

 

I'm just trying to figure out how to fix this conflict. Honestly, I don't feel like resetting my cable box, unplugging my 4K player every time I want to watch a 4K movie or when I want to watch some cable station or Amazon Prime.

Well, that's what I figured out but is there a fix for it? Because my Comcast cable box is conflicting with my 4K Blu-ray player. I don't want to have to unplug my 4K player every time I decide I watch to watch something on Comcast, because I actively use both.

It’s possible the 4K player is backfeeding something to the cable box, since unplugging the hdmi is the cure
