NETFLIX - via the Internet on your Smart TV ... tons of 4K / HDR stuff ... you just need to stream it over a High Speed Router via that TV, not your XFINITY box. If you just do NETFLIX via your Xfinity box, you won't get 4K.
acdtually if you are using a 4k set top box you will get Neflix on an X1 set top box in 4k. (xg1-v4 DVR for example).
If some has a 4K television with apps built in, They really don't need the 4k DVR box yet. Things work better for us using the television 4K Apps directly over the Internet.
Until Comcast starts linear cable in 1080P and 4K, why should we waste our time with a X1 and a 4k DVR box that have known problems not fixed yet? The DVR is currently only needed with cheaper 4K televisions that are not "smart" and don't contain the apps.
I am waiting until that time.
