Does A Second Monitor Affect FPS? ( Correct Answer Is Here )
Running the same thing on two monitors does not affect your game’s framerate (FPS).
This is because, technically, no more frames are being rendered; in this case, the game places only one frame on each screen.
However, if you “extend” your display using a second monitor (to create what is called a “Surround” setup), then the FPS will drop.
A common question among gamers is whether playing video games on two monitors will affect their performance.
There won’t be any change in the graphics card output when you run the same thing on both screens.
But when you use a second monitor to extend your screen (in other words, to make it seem like the two monitors are in different parts of the room), there will be a drop in Frames Per Second (FPS).
Why Does FPS Drop When Playing A Video On second Monitor?
When playing a video on the second monitor, FPS drops because your graphics card has to do

multiple things at once. This can result in a lower FPS.
It is recommended that when playing videos on the second monitor, you close all other programs and browser tabs.
Games with an in-game FPS counter should be minimized to avoid distraction from the game, and you should check to make sure no viruses or malware are running in the background.
Two Main Causes Of FPS Droppage
- Several applications are running simultaneously on the computer that may be using up bandwidth or processing power, such as other games or video editing software.
- The graphics card has to do multiple things simultaneously, like decoding videos and displaying them on the second monitor, leading to fewer frames per second (FPS).
Does The Size Of The Monitor Affect FPS?
The size of the monitor does not affect the computer’s FPS (frame per second) count.
What matters is the resolution power of the monitor. The higher the resolution, the higher the FPS count will be.
A bigger monitor with a higher resolution will have a higher FPS count than a smaller one with a lower resolution.
Do 2 Monitors Use More GPU?

Teasing out the idea that there is a direct correlation between the number of monitors and GPU usage. The reality is that the GPU usage will vary depending on:
- Screen resolution
- Game settings
- Other factors
Simply hooking up a second monitor to your computer will cause the power draw to go up.
This increase in demand may result in fewer FPS (frames per second) or other game-related performance issues if your system cannot keep up with two screens simultaneously.
Do Dual Monitors Cause Lag?
Yes! Playing video games and watching high-quality videos require a lot of processing power. Dual monitors can cause lag when playing video games and watching high-quality videos unless both monitors are the same resolution.
The higher the resolution, the more processing power it requires, resulting in problems for your computer.
In recent years, Dual Monitors have become more widespread as they have been used by several businesses and offices to increase productivity.
If you need to play games on both screens, it is best to connect identical monitors or reduce the resolution of one monitor, so they are equal.
Final Thoughts
Using a second monitor will not affect the frames per second. It will, however, decrease FPS when you try to run the same thing on both screens.
Adding a second monitor may cause a drop in FPS, but the speed you play is not affected. It’s more important to have a wider view of what’s going on than it is to get all the details and reaction times.
This article investigated the difference between using just one monitor and using two monitors for gaming. The single-monitor has higher frame rates than two monitors, but having two monitors means you can see more of the map.
