Thanks for your honest reply. I am surprised that the BBC HD pictures are not that great. Are you watching them through SKY? I mostly watch Netflix and free to air channels and Blu Ray. no 4K films as of yet. Have you contacted Hisense for settings?
For its price it sounds pretty good or one has to stump up some big money to go for a Samsung or OLED LG.
I run a Satellite and aerial company in Berkshire, and my engineers when they install large TVs always say that BBC pics through SKY services are poor. Its something that SKy do for some reason. Much better straight into the back of the TV for terrestrial services.
