Is your 55-inch telly just not cutting it? Fear not - Sony has all your home cinema desires realised in its new 84-inch 3D TV. The giant set boasts a 4K LCD panel, four times the resolution of a full HD set, with the ability to upscale non-4K video automatically. As for sound, you'll get a three-way 50W 10-speaker system installed on the sides of the TV - so no disappointing LCD TV sound here. Price point is still not clear, but one thing's for sure, you can expect this to be a pretty penny.
