Refresh rate

Index Refresh rate

The refresh rate (most commonly the "vertical refresh rate", "vertical scan rate" for cathode ray tubes) is the number of times in a second that a display hardware updates its buffer. [1]

Active shutter 3D system

An active shutter 3D system (a.k.a. alternate frame sequencing, alternate image, AI, alternating field, field sequential or eclipse method) is a technique of displaying stereoscopic 3D images.

Film

A film, also called a movie, motion picture, moving pícture, theatrical film, or photoplay, is a series of still images that, when shown on a screen, create the illusion of moving images.

Frame rate

Frame rate (expressed in or fps) is the frequency (rate) at which consecutive images called frames appear on a display.

FreeSync

FreeSync is the brand name for an adaptive synchronization technology for LCD displays that support a dynamic refresh rate aimed at reducing tearing and stuttering caused by misalignment with content's frame rate.

Horizontal scan rate

Horizontal scan rate, or horizontal frequency, usually expressed in kilohertz, is the frequency at which a CRT moves the electron beam from the left side of the display to the right and back, and therefore describes the number of horizontal lines displayed per second.

Interlaced video

Interlaced video is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth.

Jerkiness

Jerkiness, sometimes called strobing or choppy, describes the perception of individual still images in a motion picture.

Least common multiple

In arithmetic and number theory, the least common multiple, lowest common multiple, or smallest common multiple of two integers a and b, usually denoted by LCM(a, b), is the smallest positive integer that is divisible by both a and b. Since division of integers by zero is undefined, this definition has meaning only if a and b are both different from zero.
