Reading through these comments I can understand the concerns about poor picture quality on SD Channels. I have a 4K TV and Virgin 360 Box. Sky news is pretty dreadful, very grainy and annoying to watch. Since I have Freesat as well as Freeview, picture quality is noticeably better, also I have a Roku Box and sometimes watch Sky News on there and the picture is very good indeed. Of course, Roku is being transmitted via Internet and this will have some effect on a better picture quality. I do think also that both Sky and Virgin are charging too much extra money in order to receive HD Channels when they should now be the norm since the sales of 4K TV have been successful. After all, we live in a Digital Age and shouldn't have to pay through the nose for digital services.
