With VRR, the monitor refreshes the screen only when a new frame is available, resulting in smoother and more responsive gameplay with reduced screen tearing, stuttering, and input lag. This technology is particularly useful for gaming, where fast-moving scenes and unpredictable frame rates can cause visual artifacts and input lag, impacting the overall gaming experience.
VRR is available on some newer gaming monitors and compatible graphics cards, such as AMD FreeSync or NVIDIA G-Sync, which synchronize the monitor’s refresh rate with the graphics card’s output to provide a smoother gaming experience. VRR is also becoming more prevalent in the TV industry, with the introduction of technologies such as HDMI 2.1 and VESA Adaptive-Sync.
What is Adaptive Sync?
Adaptive Sync is an open standard developed by the Video Electronics Standards Association (VESA), which means it can be implemented by any display manufacturer and is not restricted to a single graphics card manufacturer. This technology is designed to eliminate screen tearing and stuttering in video games, resulting in a smoother and more responsive gaming experience.
Adaptive Sync works by synchronizing the monitor’s refresh rate with the frame rate of the graphics card, which ensures that each frame is displayed at the right time. This technology is especially useful for gaming, where fast-moving scenes and unpredictable frame rates can cause visual artifacts and input lag.
To use Adaptive Sync, you need a compatible monitor and graphics card that support the technology. The latest versions of HDMI and DisplayPort standards support Adaptive Sync, and many newer gaming monitors and graphics cards are compatible with this technology.
What is FreeSync + FreeSync premium?
In traditional displays, the monitor has a fixed refresh rate, and the graphics card produces a varying number of frames per second, which can cause screen tearing, stuttering, and other visual artifacts. FreeSync eliminates these issues by allowing the monitor to change its refresh rate dynamically, ensuring that each frame is displayed at the right time.
FreeSync is an open standard and is supported by a growing number of monitors and graphics cards. To use FreeSync, you need a compatible AMD graphics card and a monitor that supports FreeSync. Once both components are connected, FreeSync is automatically enabled and synchronized to deliver smooth, tear-free gameplay.
FreeSync Premium is a certification program developed by AMD to indicate that a monitor meets certain requirements for variable refresh rate (VRR) technology.
To qualify for the FreeSync Premium certification, a monitor must meet or exceed the following specifications:
- A variable refresh rate range of at least 120Hz at the monitor’s maximum resolution
- Low framerate compensation (LFC) support, which allows VRR to work effectively even at lower framerates
- A minimum 300 nits of peak brightness
- Support for at least 8 bits per color channel
- Minimum refresh rate support at 2.5:1, ensuring that the VRR range is wide enough to provide a smooth experience
Monitors that meet these requirements are certified by AMD as FreeSync Premium and are expected to provide a high-quality gaming experience with smooth, tear-free gameplay and reduced input lag.
It’s important to note that not all monitors that support FreeSync technology will have the FreeSync Premium certification. However, monitors that have the FreeSync Premium certification will offer the best possible experience when used with compatible AMD graphics cards.
What is G-SYNC?
G-SYNC uses a specialized module installed in the monitor to synchronize the monitor’s refresh rate with the output of NVIDIA graphics cards, ensuring that each frame is displayed at the right time. This technology also provides additional benefits, including reduced input lag, decreased motion blur, and improved image quality.
G-SYNC is available on a growing number of monitors and graphics cards from NVIDIA, and it is typically more expensive than AMD’s FreeSync technology. However, NVIDIA’s G-SYNC provides more advanced features, such as ULMB (Ultra Low Motion Blur) and HDR (High Dynamic Range) support, which can provide even better image quality and performance. To use G-SYNC, you need a compatible NVIDIA graphics card and a G-SYNC compatible monitor. Once both components are connected, G-SYNC is automatically enabled and synchronized to provide a smooth, responsive, and tear-free gaming experience.
Each of these technologies has its own unique features and benefits, and choosing the right technology for your gaming setup depends on your preferences, graphics card, and monitor. Some monitors and graphics cards are compatible with multiple VRR technologies, allowing you to choose the technology that best suits your needs.
