Laptop connecting a larger external monitor. Connecting two monitors to a laptop. How to connect a monitor to a laptop depending on the installed operating system
If the display on your laptop does not work or you want to display the desktop wide screen, then look at how to connect a monitor to a laptop. We will also consider what settings to use to, for example, turn off sleep mode when closing the lid.
Connecting a monitor to a laptop may be necessary in different situations. If we spend most of the day, for example, in the office, then connecting to a large display will make our work easier and allow us to use the laptop more comfortably. The monitor will also be indispensable if display damaged in the laptop. Depending on our preferences, the laptop can be configured so that we can use both screens at the same time or just one monitor (even with the laptop lid closed).
The laptop has a video output for connecting a monitor.
Depending on the model and age, they may be different, that is, the following connectors:
- D-Sub (VGA);
- DisplayPort;
- HDMI.
Before connecting an external monitor to your laptop, you need to make sure that there are compatible connectors. You should carefully check what type of connector it is, especially since in the case of DisplayPort, the video inputs differ in size (Mini DisplayPort or full DisplayPort).
If the connectors on the devices are different, then in this case you need a special adapter (the so-called “adapter”) or a ready-made cable. With their help you can connect the VGA input to DVI or DVI to HDMI. The cost of the “adapter” depends on what combination is used - the most expensive adapters connecting the D-Sub (VGA) and HDMI inputs. In the case of VGA-DVI or DVI-HDMI, the price is usually a couple of dollars. In addition to those listed, there are also USB adapters, with which you can connect multiple displays.
Let's move on directly to the process of how to connect a second monitor to a laptop. The connection itself does not require any special procedures– when you have the appropriate cable or adapter, you just need to connect the devices and only then turn them on. The monitor should be automatically detected when the system starts. By default, the same content will be displayed on both screens. Now you can do this - expand your desktop onto two screens or display a picture only on an external monitor.
Expanding your desktop to two screens
If you want to use your monitor as an additional screen, you need to enable desktop extension for two screens. Thanks to this, you can drag windows between displays and adjust them arbitrarily.
If you have Windows 10 installed, right-click on your desktop and then select "". For older systems, right-click and select "".
The settings window will open. Here go to the field called " 
» - using this menu you can select how the image will be displayed when two screens (or more) are connected.
Select the option " 
" Now the desktop will occupy the laptop and monitor screens, and you can configure other windows on each - to do this, simply drag them over the first screen so that they appear on the second.
Above these parameters there are pictures showing the connected displays. The monitor icon can be grabbed and moved anywhere to match its actual installation. Correct position monitor in the figure is done by moving windows between screens using the corresponding edges of the screen.
View image only on external monitor
For example, if the display in a laptop does not work or you just want to use it as a desktop computer and view the picture only on the monitor, then this is also not difficult to do. To do this, you will need to display the image only on the monitor, and also turn off sleep mode after closing the lid.
First, right-click on your desktop and open "" (in Windows 10) or resolution (in Windows 8.1 and earlier OSes). Then you will see pictures showing the connected displays. Your main laptop display is probably number 1 and your monitor is number 2.
Expand the field " " and select the option "Only show on 2". But, if you have monitor number 1, then select “Show only on 1”. Now the display in the laptop is completely deactivated and the image will only be displayed on the connected monitor.
Next step is the power option - set the parameters so that when you close the lid the system does not go into sleep mode. To do this, right-click on the Start button, go to Control Panel and find the “Power Options” function.
On the left, go to “action when closing the lid.” Specific meal plan options will appear.
In the “When closing the lid” section, select “No action required” in sections where the laptop runs only on battery power and, accordingly, on mains power. Save your changes. Now you can close the lid and the device will not go into sleep mode. You've learned how to connect two monitors. You can also connect a keyboard and mouse via USB and work with the device as if it were a desktop computer.
There are several variations of the connection: HDMI, VGA (also called D-Sub), DVI. Each method of connecting devices has different characteristics. Connectors differ in the following indicators:
- Bandwidth - the speed at which information is transmitted through the cable.
- Maximum allowed resolution. Measured given value in pixels and directly depends on the first indicator. The higher it is, the more pixels the image contains.
- Type of signal to be transmitted. It includes analog and digital.
In past years, a standard VGA connector was used to make the connection. Over time, the interface could no longer cope with signal transmission due to the increasing power of the latter. This entailed the need to create new connectors.
VGA (Video Graphics Array). It dates back to 1987 and is still used in technology today. The interface reproduces images with a maximum resolution of up to 1280×1024 pixels.
Initially, the connector was designed to work with, and later began to be used for liquid crystal displays.
The disadvantages are:
- inability to transmit images with quality higher than 1280×1024 pixels;
- lack of resistance to interference of natural origin;
- unclear transmission of brightness and colors.
DVI (Digital Visual Interface) is the most famous socket. The image is transmitted through it with a resolution of up to 7.4 Gbit/s.
There are several variations:
1. DVI-D transmits only a digital signal.
2. DVI-A transmits an analog signal.
3. DVI-I contains two types of transmission.
A large number of devices recognize this connector.
HDMI ( High Definition Multimedia Interface) - characterized by the ability to broadcast clips and sounds and through which you can easily connect a monitor to a laptop. This type is present on the following equipment: speakers and other devices.

Selecting cables and adapters for connection
Before you purchase an accessory cord, you need to know the type of connector. On modern devices, as a rule, HDMI is found, but there are others. In addition to the connector itself, various indicators are taken into account. To transmit high quality images from clear sound, should choose modern versions and cable specifications.
This will allow you to transfer pictures and documents, as well as stream movies and games without freezing or other problems.
USB stands out separately, which is also capable of connecting to the screen. The wire of this type will also allow you to transfer information to others electronic gadgets. In a situation where you need to connect two monitors to one PC, you should use extension cords, splitters or adapters.
We connect the monitor via HDMI to a laptop (computer)
The process of connecting the auxiliary display is carried out according to one scheme. First of all, you should be sure that all components have the same connector and select a cord for it. How to connect a monitor to a laptop via hdmi:
1. Turn off screens. Many users do not use this advice, but in vain. This action will save the equipment from damage. It happens that due to non-compliance with this simple rule or another part burns out.
2. Connecting the monitor to the device using a cable. One end of the cord is inserted into the laptop connector, the other into the screen. At making the right choice connecting wire there will be no problems with the connection. If you can't get it HDMI cable, then you can use adapters.
3. The final stage is turning on the equipment. After downloading operating system The image appears on both monitors.
The advantage is that you don’t need to go into additional settings and spend a lot of time synchronizing. Modern maps, such as Intel HD, Nvidia (for example), or AMD do not require additional adjustment.
If the picture is not displayed on the monitor automatically, then you need to manually reconnect. Hotkeys are used for this. They can be F4, F8 or others - it depends on the gadget model.
Types of projection and setting up a second monitor
After connection, adjustments must be made. The connection is made quickly and without interfering with the configuration. However, it is possible to establish a connection so that the pictures on the monitor and the connected screen are not synchronous. For example, be a continuation of the desktop or transmit a completely different picture.
Reproduction of different pictures can be obtained as follows:
- Right-click at any point on the surface. In the window, find “Settings or Screen Resolution”.
- The next step is to select a projection method. There are several types.
- Another simple and in an accessible way launch serves hotkey. It has an image of a monitor on it. For example, the F8 or F11 button depending on the keyboard brand. To activate, press in parallel with the FN key.
After opening a menu where you are asked to select a projection method, the user should click one of 4 options. The following types of settings are distinguished:
1. Play only the computer screen. And the second monitor will be turned off, but remains connected to the PC display via a cord.
2. Duplication. Both screens display the same image. This is convenient when you need to make a presentation. After all, on small screen laptop (for example, model), not all parts and details will be visible.
3. Expansion. This is the most popular transfer method. This method significantly increases working space, allows you to move the cursor from one screen to another. This makes it possible, for example, to work and play video at the same time.
4. Only the auxiliary screen functions. In this case, the other display remains black.

- Connect two gadgets with a cord with a specific interface. will help you find the attached screen.
- Searching for “Display Options”. After this, you need to click on the “second display” line and carry out the setup work.
- An important step is the choice of projection. Several options are offered. Required user selects independently depending on the purpose of the screen.
By connecting a monitor, you can adjust the brightness and clarity of images, resolution and other parameters. This can be done through the settings menu.
Connecting an external monitor in Windows 8
Each device has an output to connect to other screens. This is necessary in order to increase the working surface or simultaneously monitor two different displays. On OS 8, the connection scheme is similar to other systems.
This process has a number of advantages:
- simultaneous execution of multiple tasks;
- making a presentation using a monitor;
- the ability to display different images needed for work on the screen.
Connecting an external monitor to a laptop in Windows 7
After the connection is completed external monitor subsequent format adjustment is required for the laptop. The display attached to the device automatically adjusts to the resolution. But if this does not happen, then you need to perform the following operations:
- There is a key combination that depends on the computer model. For example, on a laptop, to switch screens, use the F8 button, which is pressed in parallel with Fn.
- Distinctive feature What Windows 7 does is that the developers have simplified the settings when using two screens. One way is the combination of the "Win+P" buttons.
- Another connection is to use the Screen Resolution menu. To do this, use the mouse to open a window, install required parameters and projection method, click “OK”.
Connecting an external monitor in Windows XP
After connecting through the cord, the image or operation is adjusted. To do this, do the following:
- Opens context menu– Properties – Screen – Options.
- The resolution is set and the number of shades is selected. There are several options: 16, 24 and 32 bit color.
- The transmission of shades is selected depending on the diagonal. The larger the monitor size, the higher the acceptable resolution.
- After the configuration, you are prompted to save the changes and click “Yes”.
32-bit color is used when the monitor itself and the video card are powerful and guarantee natural color reproduction when watching movies or playing games.
Today, monitors with a diagonal of 18 and above are popular. Detailing the pictures will help you not to miss the details in the image.
Today, many laptops are almost as powerful as desktop computers. In addition to this, they are much more mobile. However, if on the road small dimensions and weight are the undoubted advantages of a laptop, then when using it at home they are practically not felt. But it becomes obvious, perhaps the most main drawback — small display laptop. However, this problem can be easily resolved by connecting an external monitor to the laptop.
Connectors
Before purchasing, inspect the laptop to determine what interfaces (connectors) it is equipped with for image output.
The laptop may have a VGA connector, which is considered obsolete.
HDMI is a more modern connector. Often used in conjunction with the previous one. It is also used in smartphones and tablets.
HDMI connector and HDMI cable
A DVI connector is another option for connecting a monitor. Today it is considered the standard.
DVI connector and DVI cable
DisplayPort is the most new interface to display the image. It is increasingly used in laptops.
DisplayPort connector and DisplayPort cable
The next step is to select a monitor that will have the same interface as the laptop. After this, all you have to do is connect two identical connectors with a cable. If the monitor has an interface different from the one the laptop is equipped with, buy an adapter.
Setting up the connection
After connecting the monitor to the laptop, you will need small tweak. It comes down to choosing the image output option. There are three options in total:
- Outputting images to an external monitor
- Outputting images to a laptop and an external monitor simultaneously
- Outputting images to a laptop
To configure a laptop with the Windows 8 operating system, select the “Devices” button and set the appropriate display settings.
If the laptop is running Windows control XP, right-click on the desktop. In the menu that appears, select “Screen Resolution”. In the Multiple Screens tab, you will see the following options:
— “Duplicate screens.” In this mode, both the monitor and the laptop display will work simultaneously, producing the same picture;
- “Expand screen.” This mode Allows you to move windows between your monitor and laptop display;
— “Display desktop only on 1 (or 2)” -c in this case you will only be able to select one of the screens.
If you have a Windows 7 operating system, select “personalization” in the menu and go to the “screen” section. Next, we perform the settings as in Windows XP.
Even in Windows XP or Windows 7, you can use the key combination on the laptop keyboard to select image output options: Fn+ F3, F4, F5, F8 or F9. The keyboard shortcut may vary depending on the laptop model.

It would seem that it could be simpler than connecting a monitor to a computer. Here's a cable, plug one end into the connector on the monitor, the other into the computer and the job is done. But in reality, everything is not that simple.
Instructions
Previously, connecting a monitor to a computer was only possible via analog interface VGA. But a few years ago new types of connectors appeared. DVI, HDMI, Mini-HDMI and DisplayPort were added to the existing VGA. New connectors make it possible to improve the quality of the transmitted image; all that remains is to understand all this diversity, then connecting the monitor to a computer will not be a big deal.
Most worst picture allows you to connect the monitor to your computer via the VGA interface. The deterioration in quality becomes noticeable already at a screen resolution of 1024x768 pixels, and most 17-inch monitors have this resolution, so for them, and even more so for large monitors, connecting through a larger modern ports would be preferable.
Carefully examine the ones available to you to see if they have interfaces designed to connect the cable through which data will be transmitted. Both the computer and the monitor must be turned off. HDMI and DVI cords can simply be plugged into the existing connectors; the VGA cable is equipped with two screws at both ends, allowing you to securely secure the cord to prevent it from falling out during operation. After making sure that the cable fits well in the connectors, turn on the computer and monitor at the same time. If the monitor does not receive a signal, this may indicate either a faulty cable or the fact that you have plugged the cable into the connectors. Therefore, check the connection points again.
Once it starts, you can configure your monitor. If a disc with drivers was included with the monitor, it is better to install them. Most monitors function perfectly using drivers already in the operating system, but it is still better to prefer native drivers, which will significantly expand the capabilities of the monitor, for example, allow you to produce more high-quality tuning widescreen screen. After installation necessary drivers you can start working with, you have successfully connected the monitor to the computer.
To anyone modern laptop You can connect a monitor, thereby expanding the capabilities of the screen. And by putting the laptop aside and also connecting a keyboard and mouse to it, you will get regular computer with a familiar keyboard and monitor.
Instructions
By connecting to, you can not only display the image on a larger one, but also expand your desktop using the display and in your work. This is especially convenient for designers, planners, and those who need to work in several applications simultaneously.
To connect the monitor, you need to connect it to the power supply, and connect the VGA cable to a similar connector on the laptop body.
Once you have connected the VGA cable, right-click on the desktop and select "Properties" or "Personalization". Go to the “Display properties” or “Options” section and select one of the image output options: “Only”, “Monitor only”, “Monitor and laptop” (image duplication) or “Extended screen”.
By selecting only the monitor as the image output device, the image will be transmitted. If you need same picture and on the monitor, select “Monitor and Laptop”. If you need to extend your desktop, select Extended Screen.

Tip 5: How to connect your TV to your computer wirelessly
When connecting a computer to TV The problem arises - how to hide all the wires. It is necessary to take into account the placement of the computer and TV, as well as the length of the cables for connection. This problem can be solved by adding a wireless signal converter from your computer to your TV. Such a converter consists of a signal transmitter and receiver and is designed specifically for broadcasting a computer screen to analogue or digital TVs.
You will need
- VGA cable
- Wireless signal converter from computer to TV
Instructions
Connect the video output of your desktop or laptop monitor using a VGA cable to the signal transmitter.
Also connect the audio output of your computer or laptop to the signal transmitter using the included audio cable.
Turn on the signal transmitter.
Almost all laptops support connection additional monitor. Usually in two ways: via VGA or HDMI port. Less often via DVI (usually using an adapter to VGA).
Connection via VGA cable
The VGA port or, as it is also called “DB15 connector”, is present in the vast majority of both old and modern monitors, as well as in projectors.An example of a VGA connector for a computer monitor and a VGA port on a laptop is shown below.
The port can be located on the left, right, or back side of the laptop. Once connected, your laptop will likely automatically switch to the new external display. If this does not happen, you may need to press a key or key combination to switch to the external display.
The keyboard sequence may vary depending on the laptop model, but the most common keyboard shortcuts are: Fn + F3, F4, F5, F7, F8 and F9. For example, pressing and holding "Fn + F7" can switch between the laptop screen and an external display. The monitor switching feature may be labeled on the keyboard as "CRT", "LCD", or have images of two monitors next to each other.
Unfortunately, keyboard shortcuts for switching displays depend on the model and manufacturer of the laptop. If none of the above keyboard sequences work, consult your laptop's documentation or contact its manufacturer.
Note: for computers with operating system Mac system OS X version 10.8 or higher if you have a connection problem external display to your computer, open the menu, select " System Settings" and then the "Display" option. Press and hold Option key. In the lower right corner of the window you should see a “Detect” button. Click this button to force Mac OS to search for devices that are connected to your computer.
Some laptops can display video on both its own screen and an external display, or on two displays at the same time. Laptops with this feature switch between modes by pressing the appropriate function key.
Connections via DVI, DisplayPort and HDMI
New laptops and monitors can use DVI or HDMI connection. If your display has a DVI port, but your laptop only has a VGA port, you can use a video converter (or more simply put, an adapter) that converts VGA to DVI.
Newer laptops may also have a DisplayPort connector, which can be used to connect external devices display with DisplayPort cable. If your external display uses VGA, DVI or HDMI, you can also connect it to Laptop DisplayPort through a special adapter.
With the development of technology and the entry of LCD panels into the market, laptops of new models began to integrate an HDMI connector, which allows you to transmit images to high quality, as well as sound.
Connecting via HDMI is carried out in the same way as through other connectors. When connected, the image from the laptop screen will automatically be transferred to the display. The only difference is that the image quality will be much higher than through the same VGA.
