2160p

From Wikipedia, the free encyclopedia
Jump to: navigation, search

2160p is an alternative name for 4K UHD, a resolution supported by UHDTV products and which offers four times the definition of 1080p.[1] The number 2160 stands for a display resolution which has 2160 pixels along the shortest side, while the letter p stands for progressive scan or non-interlaced. In a progressive image, the lines of resolution of the image go from the top of the screen to the bottom.[2] The only planned higher definition format for television is 8K UHD.[3]

Overview[edit]

2160p or 4K UHD is 3840×2160 (8.3 megapixels in the 16:9 aspect ratio) and is one of the two resolutions of Ultra-high-definition television.[4][5][6][7]

History[edit]

  • Philips has made a 3DTV with a native resolution of 4K UHD.[8]
  • In June 2012, Toshiba launched the world's first 3D TV without glasses with 9 parallax images. The images pass through special lenticular lenses to deliver 3D effect without glasses on a 55" Toshiba Regza RZ1.[9] However, because it delivers 9 parallax images at the same time, the 3D image will only be seen as HD 720p (1280x720), since 3840x2160 = 9x1280x720.
  • Sony plans to launch a 4K UHDTV in December 2012 and more in 2013- 2020 along with 8K UHDTV.
  • The NOKIA LUMIA 930 shoots 2160p video at 30fps.
  • The NOKIA LUMIA ICON shoots 2160p video at 30fps.
  • The NOKIA LUMIA 1520 shoots 2160p video at 30fps.
  • The Samsung Galaxy Note 3(only Snapdragon 800 version) shoots 2160p video at 30fps.
  • On June 12, 2014, the 2014 FIFA World Cup became the first ever to be shot in 4K UHD, thanks to FIFA's partnership with Sony.
