Does Having Two Monitors Affect FPS? Explained

For many gamers and professional users, dual monitors have become a staple setup for enhancing productivity and gaming experiences. However, a common question arises: “Does having two monitors affect FPS (frames per second)?” This concern is especially significant for those who prioritize performance in fast-paced gaming environments or in professional scenarios requiring high graphical fidelity. This blog post delves into whether using dual monitors impacts FPS, under what circumstances, and how to mitigate any negative effects.

Understanding the Impact of Dual Monitors on FPS

When it comes to multi-monitor setups, the potential impact on FPS largely depends on how the additional monitor is used and the specifications of the user’s hardware.

How Dual Monitors Can Affect Performance

Running two monitors can influence FPS in several ways:

  • Increased Load on GPU: More screen space increases the number of pixels your graphics processing unit (GPU) needs to render, which can strain the GPU if it’s not powerful enough.
  • Depends on Usage: If both monitors are used for gaming, especially if running different games or applications that are graphically intensive, the impact on FPS can be significant. However, if the second monitor is used for less demanding tasks like browsing the web or streaming video, the impact might be negligible.

Examining the Role of Hardware

The key to understanding how dual monitors affect FPS lies in the capabilities of your hardware, especially your graphics card.

Graphics Card Considerations

  • GPU Power: High-end graphics cards are better equipped to handle the additional load of multiple monitors without a significant drop in FPS. These cards typically have more processing power and higher VRAM, allowing them to manage multiple displays more efficiently.
  • VRAM Usage: Video RAM (VRAM) is crucial because it stores the texture and pixel data for your screens. More monitors mean more VRAM is needed to maintain performance levels.

Case Study: Gaming with Dual Monitors

Consider a gamer who uses one monitor primarily for gaming while the second monitor runs a chat application and streams media. If their graphics card is mid-range, they might notice a slight reduction in FPS during high-intensity gaming scenarios. However, upgrading to a graphics card with higher VRAM and better processing capabilities can mitigate this issue.

Actionable Tips to Optimize FPS with Dual Monitors

To ensure optimal performance when running dual monitors, here are some practical tips:

  1. Invest in a Stronger GPU: If you’re serious about maintaining high FPS while using multiple monitors, consider upgrading to a more powerful graphics card.
  2. Adjust Graphics Settings: Lowering the graphics settings in your games can help alleviate the extra load on your GPU and improve FPS.
  3. Monitor Configuration: Set your primary monitor for gaming at a higher refresh rate and resolution, and adjust your secondary monitor to lower settings since it doesn’t require as much graphical power.
  4. Use Gaming-Focused Hardware: Monitors with higher refresh rates and gaming-optimized settings can help maintain a smoother experience.

Does Having Two Monitors Always Decrease FPS?

Having two monitors does not necessarily decrease FPS, but it can if your system isn’t equipped to handle the increased load. The extent of the impact also depends on whether both monitors are being used for heavy-duty tasks simultaneously.


While having two monitors can affect FPS, the impact depends largely on the specifics of your setup and how you use the additional display. By ensuring you have a sufficiently powerful GPU and adjusting your settings appropriately, you can enjoy the benefits of a dual-monitor setup without sacrificing significant performance. Remember, the key to a successful multi-monitor arrangement is balancing your hardware capabilities with your performance requirements to achieve the best of both worlds.
