Understanding the G-SYNC Borderless Issue

When experiencing G-SYNC borderless issues, it's crucial to understand the underlying mechanisms at play. G-SYNC operates by dynamically adjusting the monitor's refresh rate to match the frame rate output by your graphics card. This synchronization prevents screen tearing, a visual artifact that occurs when the monitor displays parts of multiple frames at the same time. Borderless windowed mode, also known as fullscreen windowed mode, presents an application as a borderless window that occupies the entire screen, mimicking the appearance of fullscreen mode. This mode offers the advantage of easy Alt-Tab switching between applications, but it can sometimes interfere with G-SYNC functionality, especially in multi-monitor setups.

The core of the problem lies in how Windows manages the display surface in borderless windowed mode. When an application runs in this mode, it's essentially a windowed application that's been maximized to fill the screen. This means that the Desktop Window Manager (DWM), a compositing window manager in Windows, is still involved in rendering the application. DWM is responsible for compositing all the windows on your screen, applying visual effects, and managing the overall display output. When the edge of the borderless windowed application is shared with another monitor, DWM might encounter difficulties in correctly synchronizing the refresh rate with G-SYNC, leading to the technology not functioning as expected. This can manifest as screen tearing, stuttering, or a general lack of smoothness in the game or application.

Several factors can exacerbate this issue. The specific graphics card drivers installed, the monitor's firmware, and the game or application itself can all play a role. Some games may not be fully optimized for G-SYNC in borderless windowed mode, while others might have specific settings that conflict with G-SYNC. The configuration of your multi-monitor setup, including the resolution and refresh rate of each monitor, can also influence G-SYNC's behavior. By understanding these potential contributing factors, you can begin to systematically troubleshoot the problem and identify the most effective solution.

Potential Causes of G-SYNC Borderless Problems

Several factors can contribute to G-SYNC not working correctly in borderless windowed mode when an edge is shared with another monitor. Identifying the root cause is crucial for implementing the appropriate solution. Here are some of the most common culprits:

  1. Desktop Window Manager (DWM) Interference: As mentioned earlier, DWM plays a significant role in rendering applications in borderless windowed mode. DWM's compositing process can sometimes interfere with G-SYNC's ability to synchronize the refresh rate, especially in multi-monitor setups. When the edge of the application is shared with another monitor, DWM might struggle to manage the display output across multiple screens, leading to G-SYNC malfunction.

  2. Driver Issues: Outdated or corrupted graphics card drivers are a frequent source of G-SYNC problems. Drivers are the software that enables communication between your operating system and your graphics card. If the drivers are not up-to-date or if they contain bugs, they can cause compatibility issues with G-SYNC. It's essential to ensure that you have the latest drivers installed for your graphics card.

It's worth checking the game's forums or community discussions to see if other users have reported similar issues and if there are any known workarounds.

  4. Monitor Configuration: The settings on your monitor can also affect G-SYNC's performance. Ensure that G-SYNC is enabled in your monitor's settings and that the refresh rate is within the G-SYNC range. Some monitors have specific G-SYNC settings that need to be configured correctly for optimal performance.

  5. Multi-Monitor Setup: The configuration of your multi-monitor setup can also play a role. If your monitors have different resolutions or refresh rates, it can sometimes cause conflicts with G-SYNC. Try setting all your monitors to the same resolution and refresh rate to see if it resolves the issue.

  6. Conflicting Software: Certain software applications, such as screen recording tools or overlay programs, can interfere with G-SYNC. These applications might hook into the rendering pipeline and disrupt G-SYNC's synchronization process. Try closing any unnecessary applications to see if it resolves the problem.

  7. Hardware Limitations: In rare cases, hardware limitations might be the cause. If your graphics card is not powerful enough to handle the game or application at the desired resolution and refresh rate, it can lead to G-SYNC issues. Ensure that your hardware meets the minimum requirements for the game or application.

By carefully considering these potential causes, you can narrow down the source of the problem and implement the most appropriate solution.
