Duplicate screen in Windows, basic and useful

Screen mirroring is one of the most useful functions of our computersbecause it allows to present the content that we are seeing in it exactly the same on another screen, projector or device. This function is especially useful for making presentations and that other people can see the slides on another screen, or to watch videos or movies from our computer on our television among many other uses. But, although it seems like a basic and simple task, it is not always like that, since there will be various details which it will be a good idea to pay attention to when doing it. One of the most important details of the process is the resolution: when mirroring screen, both will have the same format, the same resolution and many other common features to duplicate the content between them. This is especially relevant when duplicating a screen with different formats and resolutions, and it may happen that when duplicating, on the other screen the image is displayed at a lower resolution or in a different format, distorting it or cutting off parts of it.Samsung Odyssey G9 Monitor Another thing to keep in mind when duplicating is the performance. If, for example, we duplicate the screen playing a video game, the performance when processing the graphics of the graphics card it will be the same as if we only used the main screenbut things change when generating the image, since in this case the graphics card will have to generate the same image twiceand that especially on older devices and at high resolutions can cause performance issues when mirroring the screen and even more issues when play content such as a video.

Beyond duplication

Mirroring screens as we have just seen is a perfect option to increase the functions of our computerbut not the only one, since apart from duplicating we can extend or project on different screensand on some more advanced systems with powerful graphics supporting up to 3 or 4 independent video outputs at the same time to play video games in surround mode on multiple monitors at once or more professional assemblies.

But screen mirroring it is not usually used in those powerful computers, but in laptopssince those will be the ones that we will move to different places and that, due to their small dimensions, we will sometimes have to connect an external monitor to work with it more comfortably or connect it to a projector or large screen if we want to show other people what we are seeing on the screen. This today it is not a problemsince most computers have high-performance graphics like the graphics of the Ryzen 5000 processors in laptops, with which it is even possible to play without the need for an additional graphics cardbut it was not always like this and it is that, above all, old or very low power laptops could have problems when mirroring on high-resolution screens, and when playing content on them.
