South Korean tech giant Samsung literally rolled out the gigantic 85-inch ultra-high definition TV on Wednesday night in Sydney. The $40,000 device, soon to be available in retail outlets in Australian this month, features an Australian accent.

However, buyers such be aware that the TY has limited content available, thus Samsung is expect to sell an average of only one unit weekly, said Philip Newton, vice president of Samsung Australia.

It does not offer free-to-air content or cable or Internet TV programmes. The only content, so far, available is on hard disk drives. But Samsung said it is talking with movie producers in a bid to have more agreements that would add more content to owners of the ultra-high definition TV.

Because of its size, the gadget would definitely not fit into the family car of buyers, so part of the deal us that the company will deliver and fully install the set, offer half a day tutoring session on its use and make available a unique phone number for support.

It also has a smart evolution kit which is a slot for a circuit board that could be plugged in over the next five years to fully update it to the model of the day.

The screen is one inch bigger than Sony's 84-inch Bravia KD-84x9000 that costs $24,999 and LG Electronic's 84-inch 3D TV that costs $15,999.

Brad Wright, Samsung Sydney director, said the launch of larger TV sets is in response to consumer demand since people treat the TV as part of their design identity.
