1080p is a set of HDTV high-definition video modes that are characterized by 1080 horizontal lines of vertical resolution and progressive scan, meaning the image is not interlaced as is the case with the 1080i display standard. The term usually assumes a widescreen aspect ratio of 16:9, and square pixels, thus implying a resolution of 1920 pixels wide by 1080 high. The frame rate can be either implied by the context or specified after the letter 'p', such as 1080p30, meaning 30 progressive frames per second.

Sometimes referred to in marketing materials as Full HD, 1080p typically refers to the capability to accept 1080p signal and display it with native resolution of at least 1080 lines, as well as the capability to upscale lower-resolution material to 1080p. The HD ready 1080p logo program by DIGITALEUROPE requires that certified TV sets support 1080p24, 1080p50, and 1080p60 formats, and among other requirements, feature a native resolution of at least 1920×1080 pixels.

The filmmaking industry has embraced 1080p24 (i.e., 1080p displayed at 24 frames per second) as a digital mastering format in both native 24p form and in 24PsF form. 1080p24 has become an established production standard for digital cinematography and there is plenty of equipment capable of capturing and processing 1080p24 signals. This may be the first universal video standard, transcending continental boundaries, putting it in a category with 24-frame film.
