When you have two monitors at your desk, you can easily accomplish some of the tasks that you need to perform on your computer. The question you might be asking yourself if you are using a dual monitor setup is whether or not using multiple monitors puts more load on your GPU? Below I will give you the short answer to that question.
Well, it’s all up to you what you intend to do on a dual monitor setup regarding the type of task you intend to accomplish. If you connect your GPU to more monitors, more video memory will be consumed. If you are playing a game and want to extend the display to a second monitor, then the GPU may be put under more stress. Using dual monitors for non-3D workloads, however, will not put as much stress on your GPU.”
How Does Dual Screen Setup Affect Your GPU?
Let’s say you have two monitors with a 1080p resolution, and you would like to extend the game on both of them at the same time. However, your GPU must work extremely hard to reach the 1080p resolution on both screens. The GPU will have less work to do, on the other hand, if you are mirroring the game from the first to the second screen.
You are also putting more strain on your graphics card if you connect two 144Hz monitors simultaneously. The entry-level GPUs on entry-level computers cannot render more pixels on dual displays.
Even if you intend only to have one big screen, a dual monitor setup will not strain your GPU. In case you are using your two screens; differently, this will use more power from your GPU.
It depends on the type of programs you would like to use on each screen separately. When you are gaming on one screen and watching a 4K video on another, you will notice a decrease in the overall frame rate of your GPU.
Does A Dual Monitor System Require a Dedicated GPU?
If your motherboard has an integrated graphics card that supports dual displays, it may not be necessary to purchase a separate graphics card for connecting two monitors. You can use two monitors simultaneously if you have a motherboard with more than one video output port.
Furthermore, if your integrated GPU cannot support more than one display, you should purchase an aftermarket GPU capable of handling multiple displays. Additionally, if you use dual screens for more complex tasks, you will also require a dedicated GPU.
As long as you will be handling non-3D intensive tasks or lighter tasks, integrated graphics cards with dual monitor support should be fine. You will need a powerful dedicated graphics card to use a dual monitor setup with a high refresh rate.
Now that you know whether or not a dual monitor setup will affect your graphics card, you can decide whether or not to go ahead with the setup. It should be noted that when dealing with light tasks on two monitors, you can accomplish this without putting too much strain on your graphics card. To experience the ultimate gaming experience while playing high-end games on two screens, you will need a graphics card that will be able to deliver more horsepower.
