Whether you are in a video game or in a very important meeting, it is always useful to add a second screen or simply to outdoor project on the wall. Only here, you plug everything and everything works but nothing comes out ...

Most screens or projectors work with a VGA jack, recognizable by its blue color. This almost universal plug is very popular thanks to its reliability but has a big defect, it only transmits the image. To carry video as well as audio, prefer HDMI. The first step is of course to connect your projector (or your monitor) to the video jack of your computer, VGA or HDMI. The computer must emit a small sound when it sees your connection. It may also be that he is looking for drivers on the internet. Leave it alone and wait.

Most of the time, during the first connection, nothing happens. And that's normal. A small manipulation is required. Just press the Windows + P button at the same time. A menu appears: it is in the center of the screen under Windows 7 and on the right side on Windows 8 and 10.



As you can see, you have 4 choices:

PC screen only: this is the default option. With it the signal is transmitted only on the main screen of your computer and not on the projector (or the second screen).
Duplicate: Usually the most practical option. With it, the projector (or the second screen) transmits exactly the same image as your screen. So what you see on the screen is a copy of what is projected
Expand: This option may be useful if you want to keep one display and project another. The second screen becomes an extension of your main screen. Usually he goes to the left of your screen to you. You can drag windows and keep your computer screen anonymous. Very useful if you want to continue a job while planning something else.
Second screen only: similar to the first option but this time the signal is transmitted only on the second screen.
