I don't get this.
Why do you need an HDMI cable at all?
If you are plugging your 4K TV into a broadcast signal, all you need is an aerial (or sat) fly lead.
OTOH if you are using your 4K TV as a display for an external STB/DVD/whatever source then surely the punter expects the required cable to come in the box with the STB/DVD device, not in the box with the TV?
(FTAOD, I do know that the rip off versions of cables are not necessary - I am making a separate point)
