How to connect two monitors to the computer

The first step is check connections of both your monitors and the computer, with the cables correctly installed, whether they are HDMI, DVI, VGA or DisplayPort, depending in each case on the necessary cable. In the case of having a computer tower (the most common), the screens (normally two) will have to be connected to the graphics card or PCI through their corresponding slots.

When you connect the second screen to the computer, Windows 10 will automatically detect it by playing the typical new device connection sound; once connected, you will see a second Windows 10 desktop on the other monitor. By default, it will be configured as a monitor located next to the other, so to access it you will only have to move the mouse towards the adjacent end of one monitor to jump to the other, as if they formed a single screen.

Of course, you must keep in mind that when you join the two desktops as one, Windows 10 will respect the resolutions of each one. Thus, if one of the monitors is 4K and the other is Full HD (1080p), the result will be a desktop of 4,480x1,440 pixels, but it will only reach 1080p on the secondary monitor.

How to switch between screens

Once both monitors are connected, you can press the key combination Windows + P to access the display mode selector. This selector will appear in a pop-up column located in the lower right corner of your main screen and will offer four options for configuring monitors:

  • Enlarge | Each monitor displays a separate desktop and you can use them at the same time, moving things from one to the other; It is the default mode.
  • PC screen only | To disconnect the second monitor and use only the main monitor; The second monitor will remain connected and can be activated at any time if desired.
  • Second screen only | To disconnect the main monitor and use only the secondary monitor; The first monitor will remain connected and can be activated at any time if desired.
  • Duplicate | The secondary monitor shows the same image of the main one as a mirror.
