Does Dual Monitor Lower Fps?

Dual monitor setups have become increasingly popular for PC gaming enthusiasts. This trend has led to a common question: does having two monitors negatively impact FPS? FPS, or frames per second, is an important factor in gaming as it determines the smoothness and overall quality of gameplay. In this article, we will explore the potential effects of a dual monitor setup on FPS and whether the benefits outweigh the drawbacks.

While having two monitors can enhance your overall experience and productivity, it may not always be the best choice for gaming. Many gamers report a decrease in FPS when running games on dual monitors. This can be attributed to the added strain on the graphics card, which can lead to lower frames per second. However, this does not always hold true, and there are instances where running games on a dual monitor setup has no impact on FPS. Let’s take a closer look at the factors that determine whether a dual monitor setup will lower FPS or not.

Does Dual Monitor Lower FPS?

Dual monitor setup is a common practice among computer users who require an expanded workspace for multitasking purposes. However, some users are concerned that using dual monitors may lower their computer’s FPS (frames per second) and affect gaming performance.

Here are some points to explain the relationship between dual monitors and FPS:

– Dual monitors can lower FPS if the graphics card is not powerful enough to handle the increased workload of rendering two separate displays.
– The number of pixels on both displays increases with a dual monitor setup, which can affect system performance as the graphics card needs to work harder to keep up with the increased demand.
– If users are using different resolutions and refresh rates on both monitors, it can cause additional strain on the graphics card and lead to a drop in FPS.
– However, if the graphics card is powerful enough to handle the increased workload, users may not experience any noticeable drop in FPS.
– It is essential to ensure that the graphics card and the driver software are up to date and optimized for dual monitor setups to avoid any performance issues.
– If users experience a drop in FPS when using dual monitors, they can try closing any unnecessary programs or applications running in the background to free up system resources.

In conclusion, a dual monitor setup may lower FPS if the graphics card is not powerful enough to handle the workload. However, if the graphics card is powerful enough and the setup is optimized, users may not notice any decrease in FPS.


1. Will using two monitors decrease my FPS?
Answer: It is possible for dual monitors to decrease FPS if your computer is not equipped to handle the added workload. However, with a quality graphics card and sufficient RAM, a dual-monitor setup should not significantly impact performance.

2. Does using an external display affect gaming performance?
Answer: Yes, playing games on an external display can affect performance. The more pixels the game has to render, the more work the graphics card has to do, which can result in lower FPS.

3. Is it possible to increase FPS with a dual monitor setup?
Answer: While a dual monitor setup does not directly increase FPS, having a second monitor can free up resources for gaming. For example, you could use your second monitor to check system diagnostics or run additional programs without closing your game.

4. Are some monitors better for gaming than others?
Answer: Yes, certain monitors are specifically designed for gaming and offer features such as higher refresh rates and lower response times. These features can help reduce input lag and improve FPS.

5. What should I look for in a monitor for gaming?
Answer: When choosing a monitor for gaming, prioritize a high refresh rate (at least 144Hz), low response time (1ms), and a resolution of at least 1080p. Additionally, consider the size and panel type (e.g. IPS or TN) based on your personal preferences.


In summary, using dual monitors that have different resolutions or refresh rates may lower your FPS while gaming. However, with the right hardware and settings, it is still possible to maintain a smooth and enjoyable gameplay experience while using dual monitors. Ultimately, the impact on FPS depends on various factors and can vary from game to game. As such, it’s best to experiment with different setups to find what works best for you.
