Not on 4k (whatever that is) but I watched most of it on a lil' 'ol' 24in HD enabled TV as I had several bets on the outcome. As an aside, my Virgin Box was not switched on for several weeks over the C*s period. So, I had to go through a reactivation routine to get my TIVO box to work again and lo-and-behold I've now got a cornucopia of extra channels I did not have before including BT Sport! Still can't get the premium sky sports channels though, but appreciate Virgin's goodwill gesture as I am a very loyal customer.
I'm looking forward to the football World Cup Finals from Russia where I hope England will do well.
