How to display an image from a laptop. How to display an image from a computer to a TV? How to display test pictures on TV

As a rule, all modern TVs have quite pleasant and convenient picture settings, which most users never change at all. In most cases, the default settings actually turn out to be optimal and provide quite acceptable image quality. However, there are situations when the factory settings do not allow you to fully enjoy the picture of a film, video or program. Then there is a need to set your own parameters. But how to do this? In this article we will figure out how to adjust TV images. Let's get started. Let's go!

Modern TVs have quite nice and convenient picture settings

Let's start with the image modes that are found in every modern TV of any brand (LG, Samsung, Philips, Sony, and so on). There are at least three of them:

• Standard;
• Dynamic;
• Movie.

In almost all models, the best picture is provided by the “Cinema” (or “Cinema”) mode. In this mode, gamma and brightness are most pleasing to the eye, especially when watching movies or shows in the dark.

As for the correct color temperature, it would be best to set the “Warm” mode, since, as a rule, it is closest to the standard value of 6500 K. Some models provide several options for the same color mode, for example, in Samsung TVs: “Warm1”/“Warm2”. Here choose which one you like best, but usually the second option is the most pleasing to the eye.

If you set your TV's picture settings yourself, it is recommended that you disable all automatic picture adjustment functions and modes on your TV. We are talking about parameters such as:

• Dynamic contrast;
• Energy saving;
• Light sensor;
• Dynamic backlight.

It is advisable to disable all this and not use it.

Basic Settings

Now let's deal with one of the key and most important parameters images, namely by contrast. If contrast is considered to be the ratio of the white field level to the black level, then on TVs you will only adjust the brightness of the white field; in fact, this is the level maximum brightness pictures. If you have a plasma panel, then it is best to adjust the contrast with the lights off. Open an image with a white level window on your screen. You can download it from the Internet. Then set the contrast value close to the maximum and begin to gradually reduce the contrast until the picture with the white level is most pleasing to the eye.

Samsung TVs have a “cell brightness” item - it is this that most affects the overall brightness.

If you have a liquid crystal or LED screen, then everything is done the same way, only here a different parameter is used - “backlight brightness” or “backlight contrast”. This difference in names is due to the different design of LCD and LED TVs from plasma panels.

Please note that if the image is too bright, your eyes will tire much faster.

If “Contrast” adjusts the white level, then “Brightness” adjusts the black level. To correctly adjust the brightness level, you will need the “Plugepattern” picture. Download it and open it on your screen.

Everyone who uses a laptop in everyday life has at least once wondered how to display an image from a laptop to a TV. It is much more convenient to watch movies and images on huge screen TV.

Not all TVs have Internet access, which is why it becomes necessary to use a laptop to watch. Today I will tell you in detail how to do this.

There are many options for viewing videos stored on your laptop on your TV. Let's talk about each in more detail.

The TV screen can be used for the following purposes:

• Second monitor.

If your TV is not Smart, this mode will connect automatically. On a Smart TV you can choose the mode yourself.

• External file storage.

The laptop is used as a flash drive, and all files are managed on the TV. In principle, all methods come down to how to connect a laptop and a TV, and differ only in the type of connections.

You need to determine which of the methods described below is appropriate in this particular case. What types of connectors do your devices have?

USB cable

A USB cable is required for connection.

Find on TV USB connector, for flash drives and connect the laptop using a cable. The laptop will in this case work as an external memory card. Once the connection is established, you will see the desired image on the TV screen.

WI-FI

There are laptops and TVs that do not support Wi-Fi. If this is your case, purchase an adapter specifically designed for this purpose. Such adapters do their job perfectly.

There are two types of Wi-Fi connection:

1. Direct connection;
2. Router.

Almost all Smart TVs have WIDI technology. If the technology is not available, purchase an adapter and insert it into the HDMI connector. For correct operation, you must have the following program installed: Intel Wireless Display. Then, in the network settings on the TV, activate WiDi.

Using a router, the TV is connected to the Internet in a standard way, just like a laptop. This method described in my article:
« «.
Produce simple network settings on the TV, enter the Wi-Fi password.

If you decide to use this method, remember that speeds may vary depending on your Internet connection.

Local area network (LAN)

This connection method is preferred by many users, considering it the most convenient. Lan allows you to take advantage of all the functions of a smart TV.

As a rule, the TV setup takes place automatically. If automatic setting does not occur, you will have to configure the parameters manually or seek help from a specialist.

Network folders will become available after installation DLNA programs. There is a large selection of such programs on the Internet.

HDMI

This method is the simplest and most convenient. You can transmit both audio and video using one cable. If your devices have these ports, then by purchasing the appropriate cable, you will connect your laptop to your TV.

There are two types of HDMI cable: Standard and High Speed. Any cable works smoothly on short distances. If there is a need to increase the distance, you can purchase an amplifier.

DVI

DVI-D can easily transfer files in FullHD quality and 3D format, but without sound.

To transmit sound, you will need to use additional devices. The cable can be of different lengths. Before purchasing, it is better to check its performance.

VGA

This connector is found on many TVs older than three years.

The VGA connector has been used for a long time and has not lost popularity. However, sound is not transmitted with this connection. The cable can be found in different sizes.

This type of connector was used many years ago. Yes, and at present it is best option transfer files to old TVs. For example, view photos.

Although the image quality will not be as good top level. Laptops with an S-Video connector have long been discontinued. But if your laptop has such a connector, you can use an adapter.

RGB

This exit is often called a “tulip”.

In this case, the image appears on the TV using three channels (red, green, blue). New TV models continue to be released with such connectors. Connect to a laptop using an adapter to the VGA port.

SCART

The connector was developed many years ago, but is still found on many devices.

If there is an option to use more in a modern way file transfer, you should not use SCART, since a high-quality cable of this type is expensive, and the quality of the transmitted content is quite low.

The reasons why you want to get an image from a small computer monitor onto a large diagonal HDTV can be very different. Someone would like to know what their favorite computer game looks like on a big screen, and someone would not mind watching their favorite movies on discs comfortably and comfortably, sitting on the couch, but does not have a DVD set-top box.

All this is quite easy to solve if you know how to display an image from a computer to a TV. In principle, there is nothing complicated about this. You just need to understand a little about the standards of image input/output ports, if necessary, purchase additional equipment, connect it and configure it, taking into account some of the nuances.

1. Look at what image input/output connectors your computer and TV have. Computers and laptops usually use a 4-pin or 7-pin S-Video port, or a 15-pin standard VGA video connector for image output. Their appearance is shown in the image.

   

   
   Almost all TVs of recent years have tulip-type connectors (RCA) for video signal input. Often it can be divided into color channels and designated 3RCA (RGB). To connect a computer to a TV in this case, you will need an S-Video to RCA adapter (tulip).

   

   
   But it’s not always possible to find such an adapter, and with its help you can only get SDTV standard definition images.

   Therefore, check your availability TV VGA entrance. If it is present, then the task in this case is simplified and the computer and TV can be connected with a standard VGA-VGA cable from the monitor.

   To obtain high-definition HDTV images, computers and laptops are equipped with HDMI output ports, and televisions are equipped with similar input interfaces. In this case, the TV and computer are connected with an HDMI-HDMI cable of a suitable length.

   Since televisions can be equipped with a large number of similar appearance input and output ports, always pay attention to the direction of the signal in the connector. The signal input is always indicated English word IN and the output is OUT. To avoid damage to electronic devices, connections must be made with the TV and computer turned off.

2. After establishing a “physical” connection, it requires making some software settings.

   Turn on the TV and in its settings, specify the video source corresponding to the connection established in the previous paragraph (Component, PC, or HDMI).

   Start the computer and after it boots into the operating Windows systems Vista or Windows 7 click right click mouse anywhere on the desktop and select “Personalization” from the menu that appears.

   In the window that opens, go to the “Display Settings” component and launch it. In the Display Settings window, you should see a second inactive (gray) monitor numbered 2.

   

   
   Click directly on it and check the “Extend the desktop onto this monitor” and “Use this monitor as the main” options that become available.

   

   
   Click the “Apply” and then “OK” buttons. When prompted to save the changed display settings, click Yes.

   

   
   As a result of these steps, an image should appear on the TV screen.

   If the resolution of the connected TV is automatically determined incorrectly and black unused bars remain on the screen, you will need to launch “Display Settings” again and change the resolution on the now active second display to the required value by dragging the corresponding slider.

3. After the settings have been made, you can work with the TV screen as with a regular monitor. Run games on your computer, watch movies in a video player program, while receiving an image on a large TV diagonal.
   

Additional tip
When you disconnect your computer from your TV, be sure to set your computer screen as your primary screen again. Otherwise, you will get a blank desktop when you launch it.

There are several desktop display modes:

1. Laptop screen only
2. Only external monitor
3. Laptop screen and external monitor.
   a) Clone (duplication) mode;
   b) Desktop extension mode.

“Laptop screen only” and “External monitor only” modes

With these modes, as a rule, everything is extremely clear and understandable. If the video card drivers are installed correctly, then:

• in the “Laptop Screen Only” mode, the resolution on the laptop screen should be native, and the fonts should be perfectly straight;
• When switching to External Monitor Only mode, the native resolution of the external monitor must be set, even if it exceeds the resolution of the native display. If the monitor is connected to the laptop via the VGA port, then the only thing that may be required from the settings is to press auto-tuning button on the monitor.
  For example, a 2006 HP nx6310 laptop with an outdated 1024x768 matrix resolution should produce a 1920x1080 resolution absolutely without problems when connecting a modern monitor via a VGA connector.

Modes for combining the laptop screen and external monitor

1. Cloning (duplication) mode

If not produced additional settings, as a rule, the image cloning mode is turned on. As you understand from the term itself, all connected monitors (or projectors) will display the same image with the same resolution. In this mode (cloning or duplicating), the lowest resolution of all screen resolutions is taken as the basis. If the laptop screen has a resolution of 1366x768 and the monitor has a resolution of 1920x1080, then both screens will have a resolution of 1366x768. However, in some cases the image on the external monitor may not stretch to fill the entire screen:

Duplication mode on an Intel video card

If you have a laptop with integrated video from Intel, the setup can be done using the Intel utility.

1. Graphics options;
2. Output to;
3. Additional displays;

2. Desktop extension mode

Extended Desktop Mode requires initial setup. Sign in Control Panel and select setting Screen:

In the next window, you can configure the resolutions of all displays connected to your computer (laptop, netbook).

1. Select Expand these screens.
   When you switch modes, it doesn't matter which display is currently selected.
2. Select an external monitor.
   In our case it is number 2.
3. Please indicate its native resolution.
   Typically this is the maximum resolution available. In Windows 7 and 8, you need to move the slider all the way up.
4. Click OK to save screen sharing settings and resolutions.

Desktop Extend Mode on Intel Graphics Card

If your laptop has integrated Intel video, you can enable extended desktop mode using the Intel utility.

Right-click on an empty field on the desktop and select the following menu items:

1. Graphics options;
2. Output to;
3. Extended desktop;
4. Built-in Display + Monitor:

Later (that is, after you have configured the layout of the displays and screen resolutions), you can switch modes very conveniently Internal-Dulbbing-Expansion-External using the laptop's function key. Usually this is the keyboard shortcut FN+F4:

This is an Acer netbook:

This is a Samsung netbook:

Below we provide a screenshot of what the display manager looks like on an HP G62 laptop.

After connecting an external monitor, we select the duplication mode, desktop extension or image output to an external monitor (projector), depending on what mode we need:

When we want to turn off the output of any image to the external display, we select Computer only:

Attention! The display manager program, which is controlled by the function keys in the top row of the keyboard paired with the FN key, will look different on different laptops. In addition, different manufacturers may have different function keys for switching displays.

The idea of ​​connecting a computer or laptop to a TV may be quite reasonable if, for example, you often watch movies stored on your hard drive, play games, want to use the TV as a second monitor, and in many other cases. By and large, connecting a TV as a second computer or laptop monitor (or as the main one) is not a problem for most modern TV models.

For your computer, the connected TV is simply a second monitor, and accordingly, all settings are made in the monitor settings. On Windows 10 you can do necessary settings as follows:

In general, the setup can be considered complete at this point, except that you should make sure that the correct resolution is set for the TV (i.e. the physical resolution of the TV screen), the resolution is adjusted after selecting a specific screen in the parameters Windows display 10. If you do not have two displays, the following instructions may help: .

How to adjust the image on a TV from a computer and laptop in Windows 7 and Windows 8 (8.1)

In order to configure the display mode on two screens (or on one if you are going to use only the TV as a monitor), right-click on an empty space on the desktop and select “Screen Resolution”. The following window will open.

If you have both a computer monitor and a connected TV working at the same time, but you don’t know which one corresponds to which number (1 or 2), you can click the “Detect” button to find out. You will also need to clarify the physical resolution of your TV, as a rule, on modern models it is Full HD - 1920 by 1080 pixels. The information should be in the operating instructions.

Settings

1. Select the thumbnail corresponding to the TV with a mouse click and set the “Resolution” field to the one that corresponds to its real resolution. Otherwise, the picture may not be clear.
2. If you use multiple screens (monitor and TV), in the “Multiple displays” field, select the operating mode (more details below).

You can select the following operating modes, some of which may require additional configuration:

Apply the settings and enjoy. The best option, in my opinion, is to expand the screens. At first, if you have never worked with multiple monitors, this may not seem entirely familiar, but then you will most likely see the benefits of this use case.
