The high-quality monitor is the requirement of all gamers as well as other common peoples also which mostly use their computers for general computational needs. The reason behind this is a comfortable display of information. A high-quality monitor is necessary for all professionals also which required to use a computer most of the time in a day. Because a proper sized and high-quality display monitor does not put extra pressure on the user’s eyes.
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.
Two very famous adaptive syncs are VESA adaptive sync and NVIDIA G-Sync. AMD support VESA adaptive sync with the name of FreeSync. On the other hand, G-Sync is developed by NVIDIA which is a very famous and very specialized manufacturer of graphic cards. To use G-Sync, it is required that this sync must present on both sides including Graphics Card as well as a monitor also.
