How to connect a projector to a laptop

The article answers the question of how to connect a projector to a laptop. This guide will help you avoid common difficulties and synchronize two devices in a few minutes. What is such a connection, and how to solve common mistakes – below.

How to connect a projector to a laptop?

The latest generation notebooks support wireless data transmission. But there are also models that can be connected to a projector using a cable.

Common ways to connect a video projector to a laptop are:

  • HDMI;
  • mini HDMI;
  • VGA;
  • Wi-Fi.

There are no particular difficulties in how to connect a projector, for example, Acer P5327W, to a computer. But, if such an action is performed for the first time, incomprehensible moments may arise. Next, how to connect the projector to your laptop using the above methods.

Wired connection

To connect the projector to a computer without problems, you need to determine in advance which cable you will have to use – VGA or HDMI. In the first case, the video will be displayed in the usual TV or DVD resolution, in the second – in high definition, HD, or Full HD mode.

If you are just planning a purchase, it is worth clarifying how to connect an ACER or another brand projector to a laptop. It is best to use HDMI as it provides the highest picture quality.

Important: In the absence of the required port on one of the devices, you will have to resort to using an adapter. This reduces the image quality, but when watching movies or presentations, the difference is almost negligible.

Another problem can arise if one of the devices lacks both VGA and HDMI. This means that you will need to purchase a VGA-DVI adapter.

When connecting a laptop to the projector, it is important to remember that it is recommended that both devices be disconnected from the power supply before installing the cable. Plugging into the outlet can only be done after the cable plugs have been inserted into the ports. The projector is turned on first, then the laptop to ensure the correct display of the content.

Wireless connection

How to connect a projector to a Windows 7 laptop using a wireless network? This is done very simply. The Wi-Fi cable connects to the USB ports of both devices. If a laptop or video projector has a built-in Wi-Fi board, you can do without an external antenna.

In order for the synchronization to be successful, you will first have to install the projector drivers on the laptop. For the latest versions of Windows, starting with the seventh and higher, drivers for many models of video projectors are already preinstalled. Therefore, you do not have to download or read anything from the CD-ROM.

PC does not see the device

If the computer does not see the projector, the cause should be looked for, first of all, in the drivers. The problem is solved by installing them and then restarting the laptop.

How the picture is displayed

After the device (Acer X118H) has been successfully connected, the image on the projected surface is displayed through the menu: “Display resolution” – “Multiple screens” – “Extend these displays”.

Windows 8 makes video output even easier. In the control menu, select “Display resolution”, then you just need to press the button for selecting the external screen.

Difference between laptop and computer connections

When using Microsoft operating systems, the principle of operation of a laptop and a personal computer itself is very similar. The differences are only in the “hardware”. If the user does not connect the projector to a laptop, you can use the instructions for connecting this device to a PC.

Important: Many modern laptop models lack not only VGA and DVI inputs, but even HDMI. Instead, there is mini HDMI and USB. This means you have to use adapters.

Settings after connection

To connect the projector to your laptop without any difficulties, you just need to follow all the steps in the instructions in the correct sequence.

Most modern laptops have numeric keypads that let you start streaming videos or slides on a large screen with one click. The key is located in the Frow (from F1 to F12, depending on the manufacturer of the laptop).

The button must be pressed simultaneously with Fn.

Picture

The menu that appears after showing a picture on an external screen shows the user the following mode:

  1. Comp only. Everything is displayed only on the laptop display, while the broadcast from the projector is inactive.
  2. Duplicate. The broadcast from the laptop display takes place through the projector and is duplicated on the wall. It’s kind of a copying process. Most often this mode is used for teaching and working presentations.
  3. Expand. On the desktop, the screen is divided into two halves. Thus, the right side of the screen will be shown on the projector, the audience will not be able to see the left.
  4. Only a projector. The image is broadcast to the projector while the laptop screen is inactive.

Nuances for PowerPoint

Presentation of schematic images and slides through the Microsoft Office suite is done through PowerPoint. Its creators were supposed to be used in tandem with a projector, so it has a number of auxiliary functions that greatly simplify the work.

In PowerPoint, you can display different images: the text of a speech or report on a monitor, and a picture on a large screen. To do this, you need to go to the top menu of PowerPoint and select “Slide Show” – “Show Presenter View”.

In this mode, the presenter will be able to see on a PC or laptop not only his own text, but also a small window with information about which slides are now being shown on the large screen. This frees the person from having to turn around each time to control the synchronization of the display.

Manual setting

When displaying a video or other image on a large screen, sometimes an unexpected problem may arise – the picture will not be very clear. This may be due to out of focus (you will have to adjust it manually) or a dirty lens on the projector (you will need to wipe it with a microfiber).

Another problem may relate to the incorrect expansion, when the display shows a picture not in HD or Full HD, but in SD. Here the situation is corrected as follows: click on the right mouse button on the desktop. From the pop-up menu, select “Display”, after – “Screen Enlargement” and set the desired (for Windows 8 and 10 – screen options). For other operating systems, the procedure is the same.

Potential problems and how to solve them

Below are the most common difficulties associated with displaying video on a large screen:

There are no particular difficulties when connecting a video projector. Due to the fact that modern operating systems (operating systems) have basic settings (you can start displaying slides without installing additional software), the installation process is completed within 5-15 minutes. The most important thing to take care of before purchasing a projector is the presence of the required interface for the cable connector.
