Unsupported mode keeps popping up

The last couple of days it started.
Is this a Comcast issue or my tv. Everything is connected, nothing changed

Which X1 box?  At what point does the message appear?


I am not a Comcast Employee.
I am just a customer, volunteering my time to help other customers here in the Forums.

It sounds like a dhcp compatibility issue between your tv and the cable box (without seeing if it’s a cable box message or tv message). You may have to find an alternate way to get a connection to your tv besides hdmi
