The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio. Alternative analog video transport technologies carrying higher resolutions than 960H include HD-TVI, HDCVI, and AHD.

The Consumer Electronics Association announced on 17 October 2012 that "Ultra High Definition," or "Ultra HD," would be used for displays that have an aspect ratio of at least 16:9 and at least one digital input capable of carrying and presenting natural video at a minimum resolution of 3840×2160 pixels.

The CEA definition does allow manufacturers to use other terms—such as 4K—alongside the Ultra HD logo. [4]: 9 Since the resolution in CEA's definition is only a minimum requirement, displays with higher resolutions such as 4096 × 2160 or 5120 × 2880 also qualify as "Ultra HD" displays, provided they meet the other requirements.
