Screen Tearing issues may be unknown for most of the users. But those who are facing the issue may know how strange and annoying that while using your computer. So here we are, just pointing out what screen tearing is and the possible way to avoid that or fix them.
What is Screen Tearing
We will explain screen tearing without all the calculations regarding the screen and its refresh rate, but make it simple, we can say that the screen tearing issue causes multiple image patterns simultaneously. So you can see pictures on the screen with broken separations.
Now, a bit more detail about the screen tearing problem. As the title says, the screen tearing issue occurs in monitors, and most cases happen while playing games or some highly graphical visuals are viewed on the screen. The screen tearing is caused because of the improper working between GPU(Graphics Processing Unit) and the monitor. If an image came from GPU to monitor, and the monitor is still generating the image that has already been received, the monitor will generate the new image before completing the old one. This causes screen tearing.
So, in short, it happens due to the syncing issue between Monitor and the GPU. The monitor normally displays pictures once it received the newly refreshed signal from the GPU, Normally the screens available in the markets have a refresh rate of 60Hz, 90Hz, or 120Hz. That means each screen can refresh 60, 90, and 120 times in a second once it receives a picture from GPU.
And due to the syncing issue, the GPU continuously sends new pictures to monitor before the previous request is completed. As a result, users may notice the screen tearing issue.
How to Fix the Screen Tearing Problem
To solve this problem, we have to make sure that the sync between monitor and GPU.
If you need to completely remove the screen tearing problem, there are two options: GSync and FreeSync. Both are working based on VESA’s Adaptive V-Sync technology.
G-Sync helps you solve screen-tearing effectively, which only needs an NVIDIA graphics card in its motherboard. In addition, the G-Sync works so that it will make sure not to send a new image request to the monitor from the GPU until the monitor completes the previous request.
So with G-Sync, we can make sure that the new image will get processed by the monitor only the previous one was processed completely, which will ultimately eliminate the screen tearing issue.
Another solution to screen tearing is FreeSync, almost the same as G-Sync, but it needs an AMD graphics card instead of NVIDIA in G-Sync. However, it solves the screen tearing not in the same way as G-Sync did.
It automatically adjusts the sync by adjusting the sync rate of the monitor with the actual refresh rate of the picture processed by GPU. So, for example, if you are playing a game, the Free Sync will adjust the monitor’s refresh rate with the refresh rate of the game you are playing. In addition, it will fix the screen tearing issue on AMD Graphics Card.
To conclude, we can say that the screen tearing issue can be fixed using G-Sync on devices with NVIDIA graphics cards and using FreeSync on AMD devices.
