Does Dual Monitor Use More CPU? [Updated-Guide]

Using two monitors on the same computer is what is known as a dual monitor. This setup is possible with the presence of two graphic cards. The task can also be achieved by using one graphic card on two ports. Sometimes, this dual monitor usage affects the performance of the processor and also hampers the overall productivity of the system. But to be authentic the whole working of a dual monitor primarily depends upon the working of the GPU. So, if you are enabling your dual monitor then you should check on its GPU performance and especially the monitor’s display.

This article discusses the performance of the CPU when one uses a dual monitor. Just read the points to ponder upon the effect of the dual monitor on the CPU.

Does Dual Monitor Use More CPU?

The thing that decides the performance of a dual monitor’s CPU is the way the CPU is attached to the monitor. Whether the connection is in extend mode or in mirror mode. Always remember that connection to the monitor in the extended mode adds more load to the CPU. This causes low productivity in the system.

CPU is generally not affected by the presence of a dual monitor. But yes, a small fluctuation is seen in the graphics. The graphics are disturbed to a large extent sometimes when the load on your CPU is much more.

The next thing to keep in mind is that when you play 3D movies or films on your TV then you may notice a bit of lag in graphics and showdown on your screen. But when you have a single monitor attached to your CPU then it becomes an easy task for you to play any range of graphics and video channels at any speed.

 So, always remember to check on the performance of your system when you connect it with a dual monitor. If the CPU is working efficiently with a single monitor it is okay at all but if the processor becomes slow then you should remove one of the monitors and let the other monitor be connected as it is.

So, these were some pointers to be kept in mind while processing your connectivity of the CPU with a dual monitor.

Frequently Asked Questions (FAQs)

Why do games have 2 monitors?

Gamers usually have 2 monitors as it makes the visual experience more enjoyable and enthralling. The other screen that is present along with the previous one is used as another desktop for viewing other useful applications simultaneously.

Does dual monitor affect RAM?

No dual monitor does not affect the performance of the Random Access Memory. The playing back of multiple videos simultaneously would not affect the storage allocation of the videos.

Conclusion

Always first analyze the performance of the CPU when you connect it to a dual monitor. Although the processor is not much affected by the presence of a dual monitor but then also it is better to be on the safe side and then allow further connectivity of the dual monitor with the CPU.
