When buying a gaming monitor, it’s important to lớn compare G-Sync vs FreeSync. Both technologies improve monitor performance by matching the performance of the screen with the graphics card. And there are clear advantages & disadvantages of each: G-Sync offers premium performance at a higher price while FreeSync is prone lớn certain screen artifacts like ghosting.

So G-Sync versus FreeSync? Ultimately, it’s up khổng lồ you khổng lồ decide which is the best for you (with the help of our guide below). Or you can learn more about’s professional gaming monitors here.

In the past, monitor manufacturers relied on the V-Sync standard khổng lồ ensure consumers & business professionals could use their displays without issues when connected khổng lồ high-performance computers. As giải pháp công nghệ became faster, however, new standards were developed — the two main ones being G-Sync & Freesync.

Before we discuss G-Sync & FreeSync technologies in-depth, let’s cảm ứng on V-Sync which was one of the earlier standards created khổng lồ address the disconnect between the graphics card và display manufacturers.


What Is V-Sync? & Why Does It Matter?

V-Sync, short for vertical synchronization, is a display technology that was originally designed khổng lồ help monitor manufacturers prevent screen tearing. This occurs when two different “screens” crash into each other because the monitor’s refresh rate can’t keep pace with the data being sent from the graphics card. The distortion is easy khổng lồ spot as it causes a cut or misalignment lớn appear in the image.

This often comes in handy in gaming. For example, GamingScan reports that the average computer trò chơi operates at 60 FPS. Many high-end games operate at 120 FPS or greater, which requires the monitor to have a refresh rate of 120Hz khổng lồ 165Hz. If the trò chơi is run on a monitor with a refresh rate that’s less than 120Hz, performance issues arise.

V-Sync eliminates these issues by imposing a strict cap on the frames per second (FPS) reached by an application. In essence, graphics cards could recognize the refresh rates of the monitor(s) used by a device và then adjust image processing speeds based on that information.

Although V-Sync technology is commonly used when users are playing modern clip games, it also works well with legacy games. The reason for this is that V-Sync slows down the frame rate đầu ra from the graphics cards lớn match the legacy standards.

Despite its effectiveness at eliminating screen tearing, it often causes issues such as screen “stuttering” và input lag. The former is a scenario where the time between frames varies noticeably, leading to lớn choppiness in image appearances.

V-Sync only is useful when the graphics card outputs clip at a high FPS rate, và the display only supports a 60Hz refresh rate (which is common in legacy equipment and non-gaming displays). V-Sync enables the display to limit the đầu ra of the graphics card, to lớn ensure both devices are operating in sync.

Although the công nghệ works well with low-end devices, V-Sync degrades the performance of high-end graphics cards. That’s the reason display manufacturers have begun releasing gaming monitors with refresh rates of 144Hz, 165Hz, and even 240Hz.

While V-Sync worked well with legacy monitors, it often prevents modern graphics cards from operating at peak performance. For example, gaming monitors often have a refresh rate of at least 100Hz. If the graphics card outputs nội dung at low speeds (e.g. 60Hz), V-Sync would prevent the graphics card from operating at peak performance.

Since the creation of V-Sync, other technologies such as G-Sync and FreeSync have emerged lớn not only fix display performance issues, but also to lớn enhance image elements such as screen resolution, image colors, or brightness levels.

Those things in mind, let’s take a closer look at the G-Sync & FreeSync standards so you can choose the monitor that is right for you.


What Is G-Sync?

Released lớn the public in 2013, G-Sync is a technology developed by NVIDIA that synchronizes a user’s display to a device’s graphics thẻ output, leading to lớn smoother performance, especially with gaming. G-Sync has gained popularity in the electronics space because monitor refresh rates are always better than the GPU’s ability to output đầu ra data. This results in significant performance issues.

G-Sync ensures that when the GPU speed is out of sync with the monitor refresh rate, the graphics card adjusts its output rate.

For example, if a graphics thẻ is pushing 50 frames per second (FPS), the display would then switch its refresh rate to lớn 50 Hz. If the FPS count decreases khổng lồ 40, then the display adjusts lớn 40 Hz. The typical effective range of G-Sync công nghệ is 30 Hz up lớn the maximum refresh rate of the display.

The most notable benefit of G-Sync công nghệ is the elimination of screen tearing và other common display issues associated with V-Sync equipment. G-Sync equipment does this by manipulating the monitor’s vertical blanking interval (VBI).

VBI represents the interval between the time when a monitor finishes drawing a current frame and moves onto the next one. When G-Sync is enabled, the graphics thẻ recognizes the gap, & holds off on sending more information, therefore preventing frame issues.

To keep pace with changes in technology, NVIDIA developed a newer version of G-Sync, called G-Sync Ultimate. This new standard is a more advanced version of G-Sync. The bộ vi xử lý core features that set it apart from G-Sync equipment are the built-in R3 module, high dynamic range (HDR) support, & the ability to lớn display 4K quality images at 144Hz.

Although G-Sync delivers exceptional performance across the board, its primary disadvantage is the price. To lớn take full advantage of native G-Sync technologies, users need to lớn purchase a G-Sync-equipped monitor and graphics card. This two-part equipment requirement limited the number of G-Sync devices consumers could choose from It’s also worth noting that these monitors require the graphics thẻ to support DisplayPort connectivity.

While native G-Sync equipment will likely carry a premium, for the time being, budget-conscious businesses & consumers still can use G-Sync Compatible equipment for an upgraded viewing experience.

What Is FreeSync?

Released in 2015, FreeSync is a standard developed by AMD that, similar to G-Sync, is an adaptive synchronization công nghệ for liquid-crystal displays. It’s intended lớn reduce screen tearing and stuttering triggered by the monitor not being in sync with the nội dung frame rate.

Since this technology uses the Adaptive Sync standard built into the DisplayPort 1.2a standard, any monitor equipped with this input đầu vào can be compatible with FreeSync technology. With that in mind, FreeSync is not compatible with legacy connections such as VGA và DVI.

The “free” in FreeSync comes from the standard being open, meaning other manufacturers are able to incorporate it into their equipment without paying royalties to lớn AMD. This means many FreeSync devices on the market cost less than similar G-Sync-equipped devices.

As FreeSync is a standard developed by AMD, most of their modern graphics processing units tư vấn the technology. A variety of other electronics manufacturers also tư vấn the technology, và with the right knowledge, you can even get FreeSync lớn work on NVIDIA equipment.

Although FreeSync is a significant improvement over the V-Sync standard, it isn’t a perfect technology. The most notable drawback of FreeSync is ghosting. This is when an object leaves behind a bit of its previous image position, causing a shadow-like image khổng lồ appear.

The primary cause of ghosting in FreeSync devices is imprecise power management. If enough power nguồn isn’t applied to lớn the pixels, images show gaps due lớn slow movement. On the other hand when too much nguồn is applied, then ghosting occurs.

The Next Generation of FreeSync

To overcome those limitations, in 2017 AMD released an enhanced version of FreeSync known as FreeSync 2 HDR. Monitors that meet this standard are required khổng lồ have HDR support; low framerate compensation capabilities (LFC); and the ability to toggle between standard definition range (SDR) & high dynamic range (HDR) support.

A key difference between FreeSync and FreeSync 2 devices is that with the latter technology, if the frame rate falls below the supported range of the monitor, low framerate compensation (LFC) is automatically enabled lớn prevent stuttering & tearing.

As FreeSync is an open standard – và has been that way since day one – people shopping for FreeSync monitors have a wider selection than those looking for native G-Sync displays.

G-Sync vs FreeSync: Solutions khổng lồ Fit a Variety of Needs

If performance and image unique are your vị trí cao nhất priority when choosing a monitor, then G-Sync & FreeSync equipment come in a variety of offerings to lớn fit virtually any need. The primary difference between the two standards is levels of đầu vào lag or tearing.

If you want low input lag & don’t mind tearing, then the FreeSync standard is a good fit for you. On the other hand, if you’re looking for smooth motions without tearing, and are okay with minor input lag, then G-Sync equipped monitors are a better choice.

For the average individual or business professional, G-Sync và FreeSync both deliver exceptional quality. If cost isn’t a concern and you absolutely need vị trí cao nhất of the line graphics support, then G-Sync is the overall winner.
