G-Sync is a proprietary adaptive sync technology developed by Nvidia aimed primarily at eliminating screen tearing and the need for software alternatives such as Vsync. [1] G-Sync eliminates screen tearing by allowing a video display's refresh rate to adapt to the frame rate of the outputting device (graphics card/integrated graphics) rather than the outputting device adapting to the display ...
A typical video tearing artifact (simulated image) Screen tearing [1] is a visual artifact in video display where a display device shows information from multiple frames in a single screen draw. [2] The artifact occurs when the video feed to the device is not synchronized with the display's refresh rate.
LCD's definitely experience tearing when playing PC games. I can turn off v-sync in Bioshock and within moments I'll notice the hideous screen tearing and have to turn v-sync back on. It's already been covered that if you want to fix tearing, use v-sync. I will always turn on v-sync if the option is there, no question.
Sets 1, 2 and 3 represent the operation of single, double and triple buffering, respectively, with vertical synchronization (vsync) enabled. In each graph, time flows from left to right. In each graph, time flows from left to right.
Raster-scan CRTs by their nature must refresh the screen since their phosphors will fade and the image will disappear quickly unless refreshed regularly. In a CRT, the vertical scan rate is the number of times per second that the electron beam returns to the upper left corner of the screen to begin drawing a new frame. [ 3 ]
A vertical blank interrupt (or VBI) is a hardware feature found in some legacy computer systems that generate a video signal.Cathode-ray tube based video display circuits generate vertical blanking and vertical sync pulses when the display picture has completed and the raster is being returned to the start of the display.

1135×624 4fsc decoded frame (Luma) from a Composite 4fsc decode of a LaserDisc via ld-decode.. In a raster scan display, the vertical blanking interval (VBI), also known as the vertical interval or VBLANK, is the time between the end of the final visible line of a frame or field [1] [2] and the beginning of the first visible line of the next frame or field.
