Basic components of computer display

There are mainly two basic components of any computer display system. These components are:

  • Graphics Card
  • Display Monitor

The graphic card is also called a GPU (Graphics Processing Unit). This hardware is installed on the motherboard of a computer system. It can be in the form of an IC (Integrated Circuit) chip soldered on the motherboard of a computer or can be installed on an expansion slot of the motherboard in the form of a card. This graphics card process the graphical data and send it to the output device which is most of the cases is TV like hardware also has a screen and is called a display Monitor.

What is adaptive sync?

The processing performance of a graphics card is called “Frame Rate” while for the case monitors; it is the vertical refresh rate of the monitor. Adaptive sync is the synchronization of the graphics card and display monitor. In other words, adaptive sync is the dynamic adjustment of the monitor’s vertical refresh rate to the frame rate of the graphics card so that processed graphics data can be shown at the monitor screen at an accurate speed. If this adjustment is not properly performed, then due to the difference between these two devices working, the display of any computer system can be slow, jerky, and lagged.

Due to the above stated different reasons, adaptive sync support is must require for a proper and smooth display of the computer system. Adaptive Sync was developed for the gaming industry and is used to eliminate the tearing, hesitating, and jerk of screen for a perfect gaming experience.
