The Sharp LC80LE646E is one of the biggest television sets commercially available in the UK, but it does come with a rather steep price tag.
It is available from a number of online retailers for under £4000 but you should be able to get it from John Lewis for around £4001 by quoting the price from Appliance Direct (£4001 including delivery).
As is normally the case, John Lewis will add four additional years of warranty to the television set for free. The device comes with a Freeview HD tuner, a 100Hz refresh rate, a Wi-Fi dongle with access to Aquos Net+, DLNA compatibility, USB Timeshift+, Dolby Digital Plus, an A++ energy label, four HDMI ports, a memory card, a rated power consumption of 182kWh/year, one SCART socket, three USB 2.0 ports and two 10 Watt speaker sets.
With a visible screen diagonal of 203cm and a weighing in at nearly 60kg, you will need two people to carry it around and probably another chap to help fix it to the wall. Sharp also produces smaller 70in and a 60in television sets.
Next year will probably see the rise of smart, large screen displays that can turn full HD content into 4K2K, using proprietary algorithms and onboard processing hardware.
