I just ordered the new 4k x1 box today,want to know has anyone received thiers yet.How is it.Did it come with a 4k hdmi cord or do I need to get separately.
A High-Speed HDMI cable capable of 4K should come labelled as such. If the cable or packaging is not labelled as such it is most likely the older HDMI cable only good for HD video / audio. I have never gotten a HDMI cable from Comcast with proper labelling. You can hook it up and try it (if unlabelled) but odds are against it supplying 4K signal.
I verfied the generic cable they sent with my 4k box supports 4k.
I would be nice if that could hold true from now on for all Comcast service areas.
