How to mirror the screen in Windows

Duplicating the screen is an interesting resource for our computers. Thanks to it, it is possible to show exactly everything we are doing on our PC on a second screen, be it a television, a computer or any other device. In this post we are going to see how to mirror screen in windows

How useful is this function? There are many examples. It is frequently used for presentations, reproducing a laptop screen on a larger one. It is also very useful when we want to view a series or movie on a larger screen, like the TV screen, from our computer.

When we double the windows screen, both maintain the same format and the same resolution. This is not a minor detail, since it guarantees that the duplicate image on the second screen does not appear blurred or distorted.

And what about performance? That is a question often asked by those who use the computer to play. For the peace of mind of gamers, it must be said that when processing the graphics of the graphics card we will not notice any difference. Everything will be exactly the same as if we used a single screen. Of course, the process of generating the image will be duplicated, which can be problematic on some computers when we watch videos.

Duplicate the Windows screen step by step

The instructions that we present below are equally valid for both Windows 10 and Windows 11. Thanks to the key combination Windows + P We access the projection options menu of our equipment. This means that we will be able to access a series of functions such as duplicating the screen, extending it and even managing the video outputs of our computer.

In addition to the keyboard shortcut, we also have the possibility of accessing our computer's settings and configuring the duplicate screen from the display options.

The essential previous step consists of connect our equipment with the second screen or device in which we want the screen of our computer to appear duplicated. To do this, you must select the type of cable and the type of port that corresponds. Once this is done, these are the steps to follow:

  1. First of all, we press the keys Windows and R on the keyboard to open the projection menu of our computer.
  2. Then we use the mouse to select the screen mirroring option. In the image above, the second one shown in the menu on the right of the screen.

There is another alternative method to duplicate the screen in Windows, which we can put into operation from the settings panel. In the same way as in the previous example, the first thing to do is connect the device in which we want to duplicate the screen, using the corresponding cable and port. Then we proceed as follows:

  1. To start, we do right-click on any empty part of the desktop.
  2. In the box that opens, we select the option of "Screen settings". When doing so, the projectors, screens and monitors that we have connected are shown, with their corresponding numbering.
  3. Next you have to select home screen and access the section "Multiple Screens".
  4. Finally, we open the dropdown and select "Duplicate These Screens".

Whether we use one method or the other, after the final step both screens (the original and the duplicate) may flicker or turn off for a few seconds before the configuration settings are finally established.

These same methods that we have explained also serve to extend or project the screen of our computer to two, three and more devices, multiplying the possibilities. The limit is set by the number of independent video outputs in our equipment.

Split screen in Windows

There is another way to take advantage of the versatility of Windows with the split screen feature. The idea is to keep a single active screen, that of our computer, but split it into two or four windows to work simultaneously with several applications at the same time. For example, writing an email while talking to someone via Skype and doing Google searches.

In Windows 10 there is no specific hack to design this configuration. All we have to do is open two or four browser windows and, with the help of the mouse, adjust their size to position them to our liking.

In Windows 11 the system is somewhat more sophisticated. This operation can be carried out with the mouse as in Windows 10, or through the option snap-assist as follows:

  1. To begin we use the key combination Windows + i to access the setup menu.
  2. Then we will "System", where we select the option "Multitask".
  3. Then we display the menu "Adjust windows".
  4. To finish, we activate the option "Show snap layouts when I move the mouse pointer over a window's maximize button."
