Is 4k TV the Future?
What is 4k television?
4k television, also known as 4k ultra HD, is a display technology with a horizontal resolution of approximately 4,000 pixels per line. A 4k display creates an extremely sharp and vividly lifelike image which is being heralded as the wave of the future in broadcast television. Many industry insiders expect that 4k TV resolution is more likely to become the standard than 3D TV, owing to the fact that it creates an incredibly realistic image without the use of additional accessories.
How 4k Ultra HD Works
Technically, 4k ultra HD displays images in a 16:9 or cinematic aspect ratio, at a resolution of 3840 x 2160 pixels. This extremely dense resolution has four times more pixels than 1080p resolution, and it doubles both the horizontal and vertical resolution of the image. Thus, it is sometimes also known as 2160p resolution.
As digital broadcast and projection technologies continue to become more affordable thanks to rapid technological innovations, it is expected that 4k television will more or less become the standard within the next decade or so. Incredibly, though, it is not the only ultra-high definition resolution on the horizon. 8k TV, which offers double the resolution of 4k TV, is already in development and will likely supplant 4k TV as the standard of the future.
Though 4k TV is not yet widespread, it is already available on the market. However, though they come at a considerably inflated cost compared to lower-definition alternatives. 4k TVs cost, on average, several thousand dollars; five-figure prices are common with larger models. However, as with most new technologies, the initial prices are very high but come down rapidly with each passing year.
Numerous high-profile companies and broadcasters are already preparing for the 4k TV revolution. In 2013, Sony also revealed that its upcoming gaming console, the PlayStation 4, will support this ultra-high definition resolution for both photo and video output. Broadcast standards organizations including the Advanced Television Systems Committee (ATSC) also recently announced the adoption of standards that will support the widespread broadcast of 4k TV video at a minimum frame rate of 60 frames per second.
