Would the performance of my GPU, a GTX 1080, be negatively impacted by using dual monitors?
Using dual monitors should not significantly impact the performance of your GTX 1080 GPU. The GTX 1080 is a powerful graphics card that is designed to handle demanding tasks, including multiple displays.

When you use dual monitors, your GPU needs to render graphics for both displays simultaneously. However, modern GPUs like the GTX 1080 are designed to handle multiple displays without significant performance impact. In fact, many gamers and professionals use multiple displays with their high-end GPUs to increase productivity and enhance their gaming experience.

That being said, running more applications or processes on your dual monitors may consume more system resources, such as CPU and RAM, which may impact overall system performance. But this is not directly related to your GPU's performance.

So, in short, using dual monitors should not negatively impact the performance of your GTX 1080 GPU.
Would adding more than just one extra monitor impact my performance any further than a single monitor, or dual monitor would? or would it be the same as having one or two?
