2160p is an alternative name for 4K UHD, a resolution supported by UHDTV products and which offers four times the definition of 1080p. 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. The only planned higher definition format for television is 8K UHD.
Philips has made a 3DTV with a native resolution of 4K UHD.
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. 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 Samsung Galaxy Note 3(only Snapdragon 800 version) shoots 2160p video at 30fps.
