So, I was mis-sold Sky Q system on the basis that you could actually watch recorded content on more than 2 Sky Q mini boxes at once. I have the call recording.
Now I find I was further mis-sold. Sky clearly say that Sky Q does UHD (4K). The web site says "Watch the widest range of entertainment in Ultra HD, only with Sky Q. With up to four times the definition of HD, enjoy more than 70 movies on demand, 124 live Premier League matches and a wide selection of natural history documentaries and original Sky dramas."
The Sky Q mini is described as "Small but powerful. Simply plug in the Sky Q Mini box to watch shows and recordings from your main Sky Q box in another room in your home."
But it turns out only the main box does UHD and not on the Sky Q mini boxes.
I cannot see this restriction on the Sky web site even in the technical details.
I am starting to get rather pissed off now.
