Network capabilities of Epson projectors. Ways to connect a smartphone and phone to a projector - simple techniques with and without wires

". I often come across the question from the title. It would seem like a simple question, but not all people communicate with computers for a long time, and for them this can really become a problem. Often, this concerns teachers in schools who were given a laptop or desktop PC, installed a projector in the classroom, but were not taught how to use it - well, training was not included in the budget, and that’s it (this does not happen everywhere and not always, of course, but there are plenty of facts ).

This article will also be useful to those who do not know how to connect a monitor or TV to a computer or laptop as a primary or secondary output device, because connecting a projector, monitor and TV is similar.

So. Let's consider several possible options.

Connecting the projector to a desktop PC as the main and only display device.

The simplest option. Does not require additional hardware settings. The only possible problem is that the screen resolution set on the PC is higher than the projector can “chew.” In this case, it will display a message like: “signal not supported,” or something like that, depending on the projector. In such a situation, before connecting the projector, you will have to connect a monitor to the computer with the highest possible resolution and in the screen properties set the resolution corresponding to the “native” one for the projector, after which you can connect the projector (how to set the resolution is described below). Why “native”? After all, projectors support reception of both lower and higher resolutions than “native”! In the case when the signal and the projector have different resolutions, the projector has to recalculate the image, stretching or compressing the original image points, which often leads to minor, but still distortion, which is especially noticeable on texts - letters become uneven, and small text is generally difficult disassemble.

And so, everything is simple - connect the VGA or HDMI cable (depending on the video card and projector) to the computer and projector, and turn it on. If the video card only has a DVI output, but the projector does not have such an input, you can use an adapter to HDMI or VGA. The first option is preferable (of course, provided that there is an HDMI input on the projector), because DVI is actually the same as HDMI, only with a larger connector and the inability to transmit audio over the same cable, so there will be no additional digital-to-analog conversions and possible interference over long distances. If the projector does not automatically find the signal, press the button on the remote control or housing with the appropriate name (HDMI, VGA, DVI) or the source search/selection button (often called Source or Input).

Connecting the projector to a PC as an additional monitor.
In this case, you need a computer with a video card that has a second video output.
Accordingly, to work in a dual-monitor system, you need to take the following steps:
Windows XP— connect the monitor to the main output and turn on the PC. After loading Windows, right-click on the desktop and select “Properties”.

We connect the projector to the second output and see that we have a second monitor in the system (if this does not happen, reboot the PC, do not turn off the projector). Click on it (the second monitor) with the left mouse button and at the bottom of the window check the box “Extend the desktop onto this monitor.” Set the native resolution for the projector and click “Apply”.

Windows 7/8- right-click on the desktop and select “Screen Resolution”

The simplest option is ready. There are also options when we make the projector the main “monitor” or “clone” the image on the monitor and projector (as in the picture above), but there is a nuance. If you are interested, write in the comments, the configuration options are individual and may depend on your video card.

For those who demonstrate PowerPoint presentations on a projector, I’ll tell you a little trick, many people don’t even know about it (in fact, I know a lot of people who often give presentations and don’t know about it). In PowerPoint 2003, click on “Slide Show” in the top menu and select “Presentation Settings.”

Here on the right there is an item “Multiple monitors”, where we select the connected projector.

After you complete the steps described, your presentation (by pressing the F5 key) will be displayed on the projector, and you can solve some parallel tasks on the main monitor.

In addition, if you check the “Show presenter view” checkbox in the specified location of the settings

— during the presentation, which will be displayed on the projector, we will see auxiliary elements on the monitor, for example: notes for the current slide and the time that has passed since the start of the presentation (you need to control yourself). Here, on the left, you can see which slide will be next, and on the right you can temporarily turn off the image or end the slide show.

In PowerPoint 2010, enabling these functions is similar, only the “Presentation Settings” button is not in the drop-down menu, but just below “Slide Show”.

For those giving presentations, I have an article on my blog about how to prepare for a presentation, create it in PowerPoint, and give it. It is located at.

Well, now we come to connecting the projector to a laptop.
In principle, a laptop is the same PC, only mobile, so you can connect a projector to it by following the steps indicated in the previous paragraph, with the only exception that you do not need to connect a monitor, because it’s already there – it’s a laptop screen. Otherwise, everything is the same. But there may be nuances, plus there is an easier way to display an image from a laptop to a projector.

I am sure that all owners/users of laptops paid attention to the additional inscriptions on the function keys (F1...F12). On one of them, each manufacturer has a CRT/LCD type inscription or an icon similar to a monitor and laptop. And at the bottom of the keyboard there is an Fn key, the color corresponding to this inscription/icon. So, by holding down the Fn key and pressing the corresponding function key, we alternately switch the image display to one of three modes:
- only an external monitor (projector) - the laptop screen is black, the image is shown on the projector;
- cloning - the same image on the laptop screen and the projector. If the laptop screen and the projector have different “native” resolutions, the picture on one of them will be a little blurry. Configured in screen properties;
- only internal monitor - the image is shown on the laptop screen, the projector shows something like “No signal”.

Thus, if we just need to display an image on a projector or clone what is happening on the laptop screen, we can press this key combination. To expand the desktop, you must follow the procedure described in the paragraph Connecting the projector to a PC as an additional monitor.

Possible keyboard shortcuts for laptops from different manufacturers:
Acer or Aspire Fn+F5
Asus eee mini Fn+F8
Dell Fn+F8
Gateway Fn+F3
HP or Compaq Fn+F4
HP mini Fn+F2
Lenovo (IBM) Fn+F7
Samsung Fn+F4
Sony Vaio Fn+F7
Toshiba Fn+F5

There is another option for connecting the projector to a laptop (well, to a PC in principle) - via WiFi. But this option works with a very limited list of projectors. What is this list? I'll answer in the comments if interested. I can only say that when working with Windows 7, you most likely will not even need to install any drivers or utilities, but will only need to “connect to the projector.”

That's basically all. Nothing complicated if you know where to look. Now you know how to connect a projector, monitor, TV to a laptop or computer. If you need to connect a projector to a Mac, then you. If you want to install the projector correctly, see one of the following articles:

If you need to give a presentation from an iPad or simply connect your iPad to a projector wirelessly, read on .

There was a time when manufacturers of smartphones and other mobile gadgets tried to include a projector in the functionality of their devices. Then it might seem that you won’t need to constantly look for a projector for your smartphone.

For example, the famous Samsung Galaxy Beam model had a built-in projector for a mobile phone. But the phone itself has long been discontinued. Of course, they tried to make such attempts further, but they could not provide a truly high-quality picture.

Therefore, a reasonable question arises: how to connect your phone to a projector, which we will talk about in more detail.

Why do you need a portable projector for a smartphone - there are different situations

Situations can be completely different - an urgent presentation, an interesting video, a useful seminar for your colleagues or friends. After all, we all strive to optimize our lives, so we no longer always take a laptop on the road - often you can limit yourself to a tablet computer or phone.

Their functionality allows you to always stay in touch, solve the most urgent problems and quickly receive the necessary information. And the problem of watching videos and presentations on a big screen also fades into the background - today there are effective ways to connect for mobile devices.

We connect the projector for mobile devices as standard - using cables.

The simplest and most affordable option is to connect using a cable. Projectors have an HDMI input, and tablet computers usually have an HDMI output. If we talk about phones, here you can use an adapter from microUSB to VGA - in the worst case it will cost 100 rubles, but it will make life much easier.

How to connect a projector to a mobile phone wirelessly is more difficult, but more interesting.

Increasingly, modern models support connecting laptops and. A very convenient option when there is no opportunity or desire to work with wires. But it still requires more time and patience compared to a direct wired connection.

  • Turn on the projector, select Wi-Fi (DLNA) in the signal source settings. Here we will see the name of the network and the password for it.
  • After that, turn on Wi-Fi on your smartphone and connect.
  • Open the phone settings, here select “Screen”, then “Wireless Projector”.
  • Then, depending on the specific smartphone model, select enable signal transmission in the menu or simply select the appropriate projector from the list that appears.

This is where our efforts end - these four simple steps should be enough to fully demonstrate films or. It should be added right away that depending on the specific brand of the manufacturer, you can download thematic applications to your smartphone. For example, Casio calls it “C-Assist”, Epson calls it “iProjection”, etc. They will allow you to connect faster and provide additional functionality for setting up image display on the screen.

You can connect a huge variety of devices to your computer. All PC users should know about the features of each process. Today we need to figure out how to connect a projector to a computer. In fact, bringing your idea to life is not as difficult as it seems. The main thing is to know about some connection nuances. What should users pay attention to? What will help bring your idea to life?

Connection methods

First of all, it is important to understand that there are several options for the development of events. How to connect a projector to a computer? The user can use the following connection methods:

  • wired method via VGA;
  • wireless method;
  • using HDMI.

Accordingly, the first option is used on and the second - on laptops. There is nothing special about the process. The main thing is to act correctly. How exactly?

Preparation for the process

For example, prepare everything necessary to implement the process. You can bring your idea to life only if you have certain things. As a rule, all users have them. In any case, after purchasing the projector for sure. Therefore, there are often no problems with preparation.

How to connect a projector to a computer? To do this you will need:

  • projector;
  • computer;
  • monitor;
  • VGA wire,
  • power connection cable;
  • driver disk.

This is the most common equipment used to accomplish the task. Additionally, you need to have a separate outlet to which the projector is connected.

Instructions for working with VGA

The simplest connection is considered to be using a VGA cable. How to act in this situation? When the user has all of the listed components, a certain algorithm of actions will need to be followed. Moreover, no matter what operating system is installed on the computer.

  1. Place the projector in the desired location.
  2. Attach it to it and plug it into an outlet.
  3. Take 2 VGA wires. Connect them to the projector.
  4. Insert one of the cables into the monitor, the other into the system unit, instead of the monitor.
  5. Turn on the projector, then the computer.
  6. Install drivers for the connected device.
  7. Set the projector as a monitor in the operating system settings.
  8. Save changes.

This is all. No further special actions need to be taken. Sometimes questions arise regarding how to set up a projector instead of a monitor in the operating system. But this will be discussed later. First, you should understand all the nuances of connecting the device.

Via HDMI

You can also use an HDMI cable to work with the projector. This is a higher quality way of transmitting images. But how to connect a projector to a computer?

To do this, you will have to use the previously proposed algorithm of actions. The only difference that it is recommended to pay attention to is that the VGA cable will be replaced with HDMI. Otherwise, the instructions remain the same.

An important point is that you will initially have to work with the equipment turned off. Otherwise, there is a risk of malfunctions and problems with the projector.

Without wires

However, the methods listed are only relevant for desktop computers. You won't be able to work with a laptop this way. How to connect to a computer?

It has already been said that you can use a wireless connection. In fact, there is nothing special or incomprehensible in the process. The main thing, again, is to follow a certain sequence of actions. This is the only way to fully realize the task at hand.

To connect a projector (monitor) to your computer, you need to do the following:

  1. With the equipment turned off, insert special USB signal receivers into the laptop, as well as into the projector.
  2. Turn on the equipment. As soon as the green light on the projector lights up, synchronization with the computer will occur.
  3. Install drivers to work with the equipment. In Windows 7 they can be detected automatically.
  4. Install a program called "Connect to a projector". It is usually available on the device driver disk.
  5. Launch the installed software.
  6. Accept the existing hardware settings.

Everything is easy and simple. Now it’s clear what you need to connect the projector. The computer (Windows 7 or any other operating system - it’s not so important) must have a set of new drivers for it. Otherwise, it will not work properly.

System settings

Now a little about how to correctly display data from a computer on a projector. It is important to know about this feature. Otherwise, the projector will be connected, but it will not work.

Generally, the user should adhere to the following steps:

  1. Launch the operating system.
  2. On the desktop, right-click on any free area.
  3. Select "Screen Resolution" from the list that appears.
  4. In the "Screen" section, check "Screen 2, projector." The inscription may differ, but the meaning does not change.
  5. Save changes.

After this, the image should be transferred from the computer to the connected equipment. It doesn’t matter whether the user has Windows 7 or Windows 10 installed. How to connect a projector to a computer? From now on, the answer to this question is clear. In reality, everything is not so difficult. The main problems may arise precisely with the output of images from the computer to the projector. But fixing the situation is not difficult.

Wireless signal transmission for projectors

With the development of modern technology, the ways to reproduce a signal through a projector are becoming more and more inventive and flexible. The traditional way of transmitting the signal is to use a cable between the source and the projector,

Typically, a VGA or HDMI cable is used, or for high-performance projectors, a network cable.

Using a wired cable provides the most stable data transfer or video signal transmission, however, in a number of circumstances, using a wired connection is not convenient or possible. In today's flexible world, wireless data transmission is increasingly becoming the new standard for video playback. Every day this question becomes more and more relevant.

There are several ways to stream content wirelessly to your projector:

To choose the right method or device, you need to understand the features of these devices and select the best option to solve your problems.

The most common methods and devices for transmitting content wirelessly to a projector:

Wi-Fi adapters

Wireless HDMI kit

Wi-Fi adapters for projectors

If your current projector or the projector you are considering purchasing has a USB Type A input, chances are that projector will be compatible with an optional Wi-Fi dongle from the manufacturer. Usually it is an additional accessory to the projector. Rarely, but still happens, it comes with a projector (for example, BenQ projectors).

Not all manufacturers offer additional Wi-Fi adapters (Wi-Fi dongles), but brands such as Benq, NEC, Vivitek and Hitachi definitely have them. Typically, the cost of a Wi-Fi adapter (Wi-Fi dongle) for a projector does not exceed $100.

This form of wireless transmission is most suitable for transferring data such as Microsoft Word documents, Excel, PDF, photos, PowerPoint presentations, web surfing and short, non-capacious videos. To fully transmit a high-quality video signal and watch movies in high resolution, you should choose a Wi-Fi adapter (Wi-Fi dongle) with Full HD support.

To use wireless content transfer via a Wi-Fi adapter (Wi-Fi dongle), you need to install software from the manufacturer on your computer (a disk with the software is usually included in the kit, or you will need to download it from the manufacturer’s website). Then the Wi-Fi adapter (Wi-Fi dongle) is inserted into the USB type A port on the projector. Next, you need to establish a WiFi connection between your computer and the WiFi dongle in the projector. This is done by selecting the SSID from the list of available Wi-Fi networks on your computer that matches the WiFi adapter (WiFi dongle) in the projector.

Once connected, simply launch the already installed wireless content sharing software, it will find the projector and display the contents of the computer screen on the projector.

It is worth keeping in mind that there is a slight delay when using wireless content transfer between the projector and the signal source due to the processing time and interpretation of the data over the wireless network. This has a very minor effect for most speakers, but it's worth keeping this in mind when creating animations on PowerPoint slides, as well as live video broadcasts.

What about safety when using a Wi-Fi adapter for a projector?

You may have heard concerns about wireless technology security and information privacy. This is a completely natural concern. What if your competitor is sitting outside the building with a laptop? Can he download a presentation over a wireless network and get inside information?

Luckily, you can encrypt the signal. This is a function of the projector software. You can usually choose between 64-bit or 128-bit encryption. However, while this protects your data, it also slows down your screen refresh rate a bit. And the laptop and projector work in enhanced mode, encoding and decoding the signal. Although protecting information is sometimes a prerequisite for making a presentation.

Coverage of Wi-Fi adapter for projector

Typically, wireless transmission via a Wi-Fi adapter (Wi-Fi dongle) is limited to 10 meters, but this figure can vary significantly depending on environmental factors, the strength and speed of the WiFi signal between the source and the projector.

Apple TV is an accessory measuring 9.8 x 9.8 x 2.3cm (small enough to fit in the palm of your hand) that connects to the projector using an HDMI cable. Everything on your iPhone, iPad or Macbook can be streamed in up to 1080p resolution to Apple TV using Airplay.

Airplay lets you wirelessly stream 1080p Full HD content that's on your iOS device to a projector or "mirror" (that's what's displayed on the projector screen). Wirelessly stream photos, stream videos, spreadsheets, presentations, and the web. pages to the projector from Apple devices is possible with Apple TV.

To stream content wirelessly, your Apple TV and iOS device must be connected to the same Wi-Fi network.

Apple TV coverage

Like additional WiFi adapters (WiFi dongles), wireless signal transmission distance will vary depending on environmental factors, settings and WiFi signal.

Wireless HDMI kit

The wireless HDMI kit allows you to send content using WHDI technology. Currently, using WHDI technology, it is possible to transmit streaming video over a radio channel with a resolution of 1920 × 1080 (Full HD) at a frequency of 60 frames/s over a distance of up to 30 m at a speed of up to 145 Mbit/s. Wireless HDMI kits can
support 5-channel audio and various 3D formats.

A wireless HDMI kit consists of a transmitter and receiver, which require separate power connections for each unit. The transmitter has two HDMI inputs so you can connect multiple sources. The HDMI output on the transmitter displays the selected source on the local screen. The receiver is connected to the projector using an HDMI cable.

Most wireless HDMI kits support infrared data transmission. If the source device has a remote control, such as BluRay or HD SKY, you can use the remote control for those devices in the receiver.

Corporate or consumer?

With its expanded resolution range, 128-bit encryption, and advanced functionality, this wireless HDMI kit is suitable for professional AV applications in conference rooms and boardrooms. It can also be used in offices, schools and homes to receive signal transmission without the use of cables.

Wireless HDMI Kit Coverage

Modern wireless HDMI kits have a coverage range of up to 30 meters. Wireless sets typically use dynamic frequency selection (DFS) to select an available channel for transmission.

Wireless transmission of uncompressed Full HD video is perfectly possible using the BenQ Wireless Full HD Kit WDP01 wireless HDMI kit.

To install the Wireless Full HD kit you only need a few simple steps. Once installed correctly, the transmitter and receiver will automatically connect to the projector. By the way, the receiver, which is installed on the right side of the projector (W1070+, W1080ST+), does not require an additional power outlet. You won't have any connection problems. Please follow the instructions below if you have one of the following BenQ projector models: W1070+, W1080ST+ or W1350. If you purchased a projector that is not on the above list, you will find information on how to connect the receiver to the projector in the user manual.

Devices for wireless content transmission can be purchased from Inter Systems. Our managers will provide you with qualified advice on wireless devices and help you choose the right one based on your tasks and requirements.

Connecting a projector to a laptop is carried out through simple manipulations, but, unfortunately, difficulties are often encountered along this path. When devices refuse to pair automatically, this means that the default system settings have been lost, or that these devices simply “do not understand” each other. How to connect a projector to a laptop in this case? The connection is configured manually: for this purpose, the operating system provides certain key sets. In the absence of such, setting parameters is carried out by forcing changes in configurations.

A multimedia projector, regardless of model, connects to a computer or laptop via VGA orHDMI cable. For high quality content, HDMI will be preferable.

The connection algorithm is elementary:

  • Before turning on the projector, unplug both devices;
  • insert the plug into the corresponding connector;
  • turn on the projector, then the computer.

In cases where the required connector is not available, you can use special adapter. This can happen when the video card only has a DVI connector, but the projector has VGA or HDMI. Using an adapter slightly reduces the quality of the content. The projector turns on first, otherwise the computer does not see it.

Special adapter

Wireless connection

You can also synchronize devices via the Wi-Fi protocol; today this method is gaining popularity. To activate you need install drivers, but in the case of Windows 7, usually the standard ones are sufficient.

If the disc is lost, the application can be downloaded online from the projector brand website.

Before you connect the projector to your laptop, you need to install Wi-Fi antennas in the USB connectors of the projector and PC; in appearance, they resemble a small flash drive. The green indicator light informs you that the connection was successful.

It is worth noting that not all projectors that supportWi-Fi, they will project video. Some models can only be connected to control equipment; this nuance must be clarified when purchasing. A wired connection is more reliable and practical: the HDMI plug, for example, is designed to transmit excellent quality video without interference.

Displaying content in the required mode

Theoretically, after connecting the cable to the appropriate connector, the picture should be displayed automatically. In some cases, when the settings are incorrect, the user must make the necessary changes to display the content. It is known that each version of the operating system has its own characteristics, therefore there is no uniform procedure for action.


Then, the user has access to four picture display modes connected projector.

  1. Duplication (repetition) – when video from a computer or laptop is duplicated on an external screen.
  2. Computer only - content is played on the laptop display, and the external screen is not used at this time.
  3. Expansion - the desktop is divided into two parts, its left side is displayed on the PC monitor, and the right side is displayed through the projector.
  4. Projector only – information will be projected only on a large screen.

Useful tips for Power Point

The office program Power Point is “tailored” for presentations; it is often used because it is simple and convenient. This has its own operating features, for example, you can display slides on a large screen, and the text of a report or lecture on a PC display.

The settings don’t take much time: after synchronizing the projector with the PC, go to the program and in the top panel look for “Slide show” - “Show presentation”. Check the box next to “Projection equipment”. Here you can find “Speaker Mode”; if you activate it, various auxiliary tools for conducting lectures will be displayed on the screen - additional buttons or notes.

Manual image debugging

Sometimes pictures or letters are blurry or “floaty” - this happens when the monitor resolution settings on the PC are incorrect. To maximize quality, set your computer's resolution to match the projector's specifications. In this case, the projector settings do not change.

How to change settings on a computer/laptop (for the platform Windows 7/Vista):

  • to go into the computer settings, you need to open the menu with the right mouse button (click on the desktop);
  • select “Screen resolution” and set the correct value (like the projector);
  • Save the settings by clicking the “Ok” button.

OptionsWindows 10 slightly different, here the “Resolution” item is located in the screen settings section. Click "Start" and find the "System" tab, on the right side of the window, scroll to the bottom of the page and open "Advanced display options." Then everything is simple: select the desired value and save the settings.

This completes the task of how to connect a projector to a computer. After connection, the user can select a convenient output mode for holding a presentation or watching a video at home.
