Nowadays, the vast majority of laptops are equipped with video output. Very useful for connecting to a video projector and projecting the screen of your laptop PC during a conference for example.
How to connect a video projector to a laptop PC?
We invite you to see the different projection modes and especially to learn how to connect a video projector to a laptop PC.
Choosing the right cable: a connection story
To connect a PC to a video projector, you will have to buy a cable. Depending on the connection present on your PC and that present at the input on the video projector, it will be necessary to use an HDMI cable, a VGA cable, and possibly an adapter. We will always connect an HDMI cable to an input and an output of the same name. The same goes for a VGA cable. If on the PC or projector side, the inputs/outputs are not the same standards, then you will have to buy a small adapter/converter in order to obtain HDMI to VGA (or vice versa). Generally, all laptops have an HDMI input, so do not hesitate to use it to have an image quality superior to VGA and also the sound of your computer.
The different projection modes
Windows offers several ways to project what is happening on your computer screen. Each method has its pros and cons. Let’s take a look at the different ways to project your screen.
First, the “Screen mirroring” mode. This means that the projector will broadcast the video stream from your computer screen to the projector without changing the scale or resolution. Although it may seem practical, this mode is not necessarily the most suitable, unless the video projector natively accepts the same resolution as that of your PC. In simpler words, if your computer is set to Full HD, your projector will have to accept Full HD at native resolution, at the risk of seeing the image distorted.
Extend the desktop
Here Windows will use the projector as a second screen. The desktop will therefore be accessible on your main screen, but also on the projected image, in an extended manner. This means that you will feel like you have two desktops and can slide windows from one screen to the other. The advantage of the desktop scope is that you can set the screen resolution independently. If your projector is 720p HD and your computer is Full HD 1080p, this won’t be a problem.
Use only the second screen
The purpose of this method is to use only the screen of the video projector. Thus, your screen will go out, leaving only room for the projected image. This solution is optimal for the resolution and the non-distortion of the image. However, if the screen is behind you (such as in an oral presentation), this will not be the most convenient method.
