When it comes to 3D TV, bigger is always better. At 60 inches, Samsung's UE60D8000 is one of the largest screens you can get in your house before going into 3D projector territory, and is backed by an impressive array of connected TV features. However, it's also one of the most expensive sets we've ever tried, nearly £1,000 more than its 5-inch smaller stable-mate at around a whopping £3,350. Does the TV perform well enough to justify the price tag?
