Basic components of computer display

There are mainly two essential 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 installed on an expansion slot of the motherboard in the form of a card.

This graphics card processes the graphical data and sends it to the output device, which, in most cases, it is TV-like hardware that 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 monitor’s vertical refresh rate. 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 graphics card’s frame rate so that processed graphics data can be shown on the monitor screen at an accurate speed.

If this adjustment is not performed correctly, 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 reasons, adaptive sync support is required for a proper and smooth display of the computer system. Adaptive Sync was developed for the gaming industry and is used to eliminate the screen’s tearing, hesitating, and jerking 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 was 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 be present on both sides, including Graphics Card as well as a monitor also.


At the end of this article, after reviewing all these best gaming monitors with 4k quality displays and supporting G-SYNC adaptive sync, you must be able to clearly understand the difference between different screen resolutions and the effect of adaptive Sync.

In this list, monitors of various sizes are available for your final selection according to your requirement, required specifications, and, most important, price range.

You must go for one of these which is according to your needs. Your comments are a source of encouragement for me to improve my work which is just for you. So stay in touch and keep commenting.
