I’m sure by now you’ve heard of 4K Televisions, or sometimes, as they’re referred to, ‘Ultra High Definition’ televisions. Somewhere else you’ve probably heard about 4K is through TV broadcasters advertisements, when they’re talking about showing programmes in Ultra HD.
4K simply means ‘four thousand’ and it gets its name from the approximately 4,000 pixels width of the footage being filmed. To be precise, a 4K image has a horizontal dimension of 3840 pixels and a vertical dimension of 2160 pixels.
