The 4K TV set is ultra-high definition with unbelievable clarity. It packs twice the horizontal and vertical resolution of full HD TVs, the 1080p ones. It has a resolution of 3840 x 2160 pixels, compared with the 1920 x 1080p of a full HD set. These TVs had sizes of 82 inches plus to accommodate high pixel density. They are too large for most households. Broadcasters are still struggling with full HD channels. It is not possible for them to beam 4K content, which is four times heavier, right now. This is changing. Sony’s 4K models are 55 to 65 inch, priced at Rs 3 to Rs 4 lac respectively. It is likely that Samsung and LG will follow suit. However, the chances of  of a 4K channel in India are not so good. Elsewhere, the content is supported by a pre-loaded 4K media player. There is also 8K in the offing which is 16 times the number of pixels of full HD. It is difficult to say that this will be future TV.
