Connecting a TV to a laptop via hdmi. Connection port malfunction

The compact size of a laptop is convenient on the road or at work, but at home a diagonal of 14-17 inches is usually not enough for comfortable viewing of videos and other entertainment. Why not transfer the picture from your laptop display to your modern widescreen TV using HDMI? In practice, this is easier than it sounds. In general, first things first.

General information

Connecting a laptop to a TV using an HDMI cable allows you to transfer sound and picture. This does not require any specific knowledge and complex settings. The only prerequisite is support for HDMI interfaces on both devices.

In this example, we will connect an old 10-inch asus laptop to a samsung TV with a diagonal of 81 cm.

Preparation

So, to connect a laptop to a TV via HDMI, we need:

• 10-inch laptop;
• widescreen samsung TV;
• special HDMI cable;
• quite a bit of time

It remains only to find the necessary connectors (usually signed) and connect both devices, but where to get the cable?

We connect the TV

For TVs of the Korean brand Samsung, an HDMI cable is often included in the package. In other cases, you will have to go to a computer hardware store.

Connecting hdmi cable to laptop

The only drawback of HDMI technology is the different quality of the cables sold. Therefore, the purchase must be approached responsibly.

Important: connect two devices to each other only after turning them off.

Setting up your TV

The difficulty lies in the impossibility of compiling a universal instruction for setting up all TVs. Even in different models of the same brand, the steps for connecting external devices sometimes differ.

In short, you need to go to the choice of the source of the image. Usually this is a button on the remote, which is popularly called "exit", located in the upper rows.

Click on it and you will see a list of all possible sources for displaying images on the screen: antenna, USB flash drives, card reader (if any) and HDMI.

So you need to activate it by highlighting and pressing the selection button (usually this is "OK").

Laptop settings

Since the laptop is already turned on, and the default HDMI cable turned out to be of high quality, the TV will probably immediately display the picture from its display. That is, the settings as such are not required.

Now you can view photos on a large screen, stream video files from your hard drive, run games.

If something went wrong

Difficulties occasionally arise. For example, the TV set distorted the resolution or there is no image at all, and instead of it there is a black screen (the logo of your TV brand floating on it confirms the absence of a signal from the laptop). What can be done in this case?

On Windows 7, hold down the keys Win + P... This action will display a menu of ways to display the picture on the TV screen.

In this menu, you need to choose the most convenient option for displaying the picture.

If it doesn't work, follow these steps:

1. Right-click on the desktop to bring up the context menu
2. From the list go to "Screen Resolution"
3. In a new window, next to the "Screen" label, set the value "Multiple monitors"
4. Opposite the inscription "Multiple screens" set "Duplicate these screens"

This is usually enough for the picture to appear. You can also adjust the resolution right there.

If you want the sound to come from the TV speakers, then in Windows, right-click on the speaker icon in the lower right corner and open "Playback Devices". There, just select your TV.

Using such a system, you are probably an advanced user and know the peculiarities of its configuration. Since the sound from the TV itself is usually needed to watch video directly from the laptop, you can simply select the audio output device in the video player. Such features are supported, for example, by the VLC player.

Output

Connecting a laptop to a large screen with an HDMI cable is easy and opens up great possibilities for using the computer for home entertainment and work. In most cases, no configuration is needed. All you have to do is select HDMI from the list of devices available to your TV and you can enjoy your laptop's workspace on an enlarged scale without loss of picture and sound quality.

Today, any user using an HDMI cable can, as well as a desktop computer, to a flat-screen LCD TV, and then enjoy an expanded image. Such a connection is not always successful: for example, it can. But there are times when the computer does not see the TV connected via HDMI at all, although you just purchased the wire in the store, where it was tested in various ways. There are many reasons for the cable malfunctioning, and the search for the true problem must be done consistently.

We carry out diagnostics

What should be done if the TV cannot see the laptop via HDMI? Video cards of all modern products support such a connection: HDMI is installed on the TV on almost every model. If the laptop was connected in accordance with all the rules, but still there is no image, then we connect the laptop to the TV, while sequentially checking all possible problems.

Cable check

Not a single product, even the most reliable brand, is immune from factory defects, especially when assembled by hand. When buying, the image quality and sound are checked, but they never check specific connectors and connection jacks on the TV - at best, they make sure they are available, and even then not all buyers. It often happens that the cable itself does not work, although it has not been used for so long. It is necessary to connect the same cable, but to another device, if it functions normally, then the reason that the computer does not see the TV lies in the latter. It is necessary to diagnose the TV in order to recognize similar signals.

Checking the signal source

On the remote control (RC), press the button to select the external input option. The specific model of the product depends on which button on the TV remote control you need to press: “source”, “input” or “HDMI” (LG, Sony or Samsung). After pressing, a menu appears on the screen with detailed list of active inputs... We select and confirm by pressing OK or Enter, it is the desired input, into which the cable from the laptop was previously connected.

Working with the monitor

If the laptop does not see the TV when multiple monitors are connected at the same time, then it is necessary to carry out additional settings... These simple manipulations can be performed by any user without special education:

• hover the cursor over any free space on the desktop;
• for the menu to appear, click on the right mouse button;
• we find the section "screen resolution" - Windows 7, and if there is WindowsXP, then "graphic characteristics";
• then you need to choose an acceptable option to duplicate the screen.

Any laptop has a specific F4 key, if you press it together with the Fm button (located to the right of Crtl) repeatedly, you can select the desired option for the external screen - this is how the computer starts to see the TV.

Graphics card and drivers

Open the "Device Manager" of your laptop to check the driver versions of the installed video card. Outdated software is the main reason why the TV does not see the laptop. In this case, you need to go to the manufacturer's website, where you can download new "firewood" - the video card will be updated, you can establish the required connection.

Perhaps the fault lies in the fact that the operating system was infected with viruses or there was an unauthorized entry of malware. Using a powerful antivirus (computer protection program) capable of finding all spyware of any level, we thoroughly scan your computer and reconnect.

Some experts strongly advise you to check the version for your Smart TV platform: sometimes a laptop cannot be connected via HDMI for this very reason. and maybe the problem will go away.

Connection port malfunction

Any connector can have mechanical damage or burn out during a power surge, which are not uncommon in our electrical networks. Experienced craftsmen advise connecting the HDMI cable when disconnected devices, even the antenna cable is recommended to be disconnected for this time.

There is also such a very rare reason why the TV does not see HDMI: it simply does not have additional power on the video card, and without this the connection will not work.

All details and connection options can be viewed using this video:

Troubleshooting Algorithm

If you know the reason why there is no image on the TV screen, then the elimination of various violations is already a solvable task. This is how the approximate procedure for eliminating the detected faults looks like:

1. Check the quality of the connection, visually check the external condition of each connector or connecting cables, if the laptop stopped seeing the TV.
2. Then the configuration of the computer systems is checked: check what selection was made in the menu items responsible for connecting devices.
3. Check for updated graphics card drivers.
4. In some cases, it doesn't hurt to check the settings of the video card itself once again.
5. Re-scan the entire computer with a Smart Scan to ensure no malware.
6. Check visually the condition of the multimedia ports, their proper operation - a positive result will be immediately visible when connected to another device, for example,.

If you have tried your best and the laptop still has no signal to the TV, try other connections. Use the rule of thumb when all existing connection methods are used consistently. The due diligence process will look like this:

• first, we determine the available connections and connectors that are used by our selected household appliances;
• disconnect TV and laptop from the network;
• we connect the laptop to the TV using a proven HDMI cable;
• turn on the TV, setting up its connection to the computer using the remote control;
• we activate the laptop, if the signal passes, then a picture should be displayed on the TV screen, similar to the loading of the operating system;
• no signal - go to the "Device Manager" section, find out what active types of connection are available;

• if it is possible to install VGA connection, then you need to connect a similar cable to the products;
• then we carry out similar actions as with HDMI, only press the "VGA" button on the remote control;
• if you decide to make a connection via DVI, then we connect the cable to the corresponding connectors, select the same option in the TV settings.

If the technician did not start working together, the reason lies in an internal breakdown, which can only be diagnosed and eliminated by a master. Of course, if you have knowledge of the electronic stuffing of devices, you can give it a try.

The compact laptop is ideal for work or on the go. However, at home, a regular screen is not enough to comfortably watch a movie. The way out is quite simple - connect the laptop to the TV via hdmi. The procedure is simple, no special knowledge is required, it will be enough to follow the recommendations presented below.

Some useful information about HDMI

Nowadays, HDMI technology is used everywhere. It provides high-quality video and audio transmission. This uses only one cable.

At the moment, several standards are available to users:

• standard 1.0,
• standard 2.1.

Between themselves, they differ in transmission speed, as well as the number of supported audio channels.

Today, many companies produce HDMI cables for connecting a laptop to a TV. Branded products are quite expensive, but there are also budget models on the market with an acceptable price. Although many modern TVs are immediately equipped with a similar wire.

We understand the intricacies of connecting a laptop to a TV

Any user can figure out how to connect a laptop to a TV via hdmi. To do this, we adhere to the following plan:

In general, four modes are available to the user, and regardless of which version of Windows operates on the PC:

• only computer - signal transmission to TV is not provided;
• duplication - a picture from a PC is displayed on the TV screen;
• expand - two screens open, from one there is a signal to the TV, on the other you can perform any manipulations;
• projector - the signal will not be displayed on the computer, only on the TV.

Usually the resolution is automatically adjusted. You can make changes yourself, go to the screen settings on your computer.

We provide sound transmission

Even after figuring out how to connect hdmi from a laptop to a TV and getting a picture, there may still be no sound. In order for the sound to start working, you will need to refer to the settings in the operating system. Click on the speaker icon in the notification panel, go to the "playback devices" item.

A menu will launch, it will contain a list of devices capable of playing sound. Find the TV, right-click on it and activate the "use by default" item. After these actions, a sound will appear.

Why can't I connect

Oddly enough, connecting a laptop to a TV via hdmi can be extremely difficult. You may encounter certain problems that require immediate solutions.

Let's consider the most common:

1. The laptop cannot see the TV. Such a malfunction can occur for two reasons - a broken cable or connector and an error with the video card drivers. The latter are the easiest, they just need to be updated. You can check the functionality of the cable using another. With the connector, everything is much more complicated, without special equipment it is difficult to do this at home.
2. The laptop does not see the TV. This happens very rarely, for example, on Samsung TVs because of Smart TV. The issue is resolved with a software update. An incorrect signal source may also be selected. While it is of the utmost importance to check the cable, it is this cable that is the main source of problems.

How to connect to an old TV

HDMI is a fairly young format, old TVs are simply not equipped with such a connector. However, there is a connection option. Next, let's figure out what to do in a similar situation. First, we inspect our TV and examine all the available connectors. There may be such options:

1. Composite.
2. Component.
3. SCART.
4. S-Video.

You can connect to all of these connectors; all you need to do is visit the store and purchase an adapter, for example, HDMI-VGA or any other option. Please note that connectors such as composite, component and SCART provide the ability to transmit sound. The rest are adapted only for broadcasting images.

What to do if your laptop is missing an HDMI connector

In general, it is quite difficult to find a laptop that does not have this connector. It is possible that it is not working. In any case, the connection can be made. Any PC has a USB connector, and almost everything can be connected through it. Also, many modern TVs support Wi-Fi.

There are two ways to act. The easiest way is to purchase a USB to HDMI adapter. Although it is quite rare and not cheap, it allows you to connect with the least difficulty.

You can also connect wirelessly using Wi-Fi Direct or WiDi. But it will be difficult for an ordinary user to make the necessary settings.

In conclusion

As you can see, connecting a laptop to a TV via HDMI is quite simple. There is no need to make serious adjustments, just connect the cable to the devices and activate the required signal sources. After that, endless possibilities for entertainment and work will open up.

Today there is no need to buy expensive discs to watch your favorite movies. The Internet offers free online multimedia. For convenient viewing, advanced users use a TV screen as a monitor. In this article, we will analyze how via HDMI.

The main advantage of this interface is the support for high resolution, which the VGA-connector cannot boast of. In old TVs, a tulip is most often used to connect external devices, and new ones already have a jack for HDMI.

To connect an old TV model, you will have to try, since the search for a suitable cable with the necessary interfaces does not always end successfully. In any case, special adapters will always come to the aid of users. Keep in mind, however, that the fewer connections, the better the image. Therefore, if it is possible to buy a cable with the necessary connectors, then it is better to exclude the use of adapter devices.

Since it is easy to connect HDMI, we will not consider the order of connection by colors (if a tulip is connected to the TV). After the devices are connected, the TV turns on, then the computer. While the operating system is loading, a flicker will appear on the screen. This means that it is connecting to an external device. It is necessary to switch the TV to audio and video input (on the remote control this is the AV key). Thus, an external signal is connected to the input.

In the properties of the video adapter, you must identify the new monitor. If you are using a new operating system Windows 7, then right-clicking on the desktop with one click brings up a window where you need to select the parameter item. In the menu that appears, click the "Find" button. And the TV will show the picture.

We've covered how to connect a laptop to a TV via HDMI. With the help of such a connection, the need to huddle at a computer monitor with the whole family disappears by itself, because now you can watch your favorite online program on a large screen. Some users manage to hide the cable from the computer to the TV behind the baseboard, conveniently placing it in a special compartment. However, this will have to sacrifice image quality, because in order to hide the cable, you need to use a long cord.

In recent years, the HDMI connector has gained more and more popularity because, unlike other ports, it has the ability to carry audio. Absolutely all laptops are equipped with such a connector, thanks to which you can easily connect to a TV and display the image on a large screen. Consider what you can do if HDMI is not working on your laptop, depending on your situation.

What's the first thing to do?

First, you need to determine what caused the problem, since the methods for solving it may differ depending on the situation.

A common occurrence is that HDMI does not work on a Windows laptop, that is, after the connection has been made, you only see an empty desktop on the screen. The problem here is not the connector or the cable. The fact is that the TV here acts as an extension of the laptop screen, i.e. it becomes an additional area of ​​the desktop. To see the window in this situation, it will be enough just to move it to the left or right.

This is not enough for correct operation, so you need to switch the display to full duplication of the desktop. To do this, proceed as follows:

If the HDMI output on your laptop is not working, this method will fix the problem.

The laptop sees the connection, but there is no picture on the TV display. First of all, you need to check the connection. The wire must sit firmly, carefully inspect it for damage and kinks. If they are present, the cable will have to be replaced.

If everything is in order with the cable, there is no damage, then you need to check whether the correct socket has been selected. Often TVs have several ports at the same time, but the signal reception in the settings is set to only one port.

Everything is fine with the picture, but there is no sound. In this situation, your task is to route the audio signal correctly. To do this, do the following:

If HDMI stopped working on a laptop, while all the above steps did not help in any way, then you should check if the port itself is in working order. Sometimes they burn out - of course, you have to carry the laptop to a service center. To avoid such a problem, it is imperative to disconnect the cable and satellite dish from the TV before connecting. If the outlet that supplies power is not grounded, disconnect power from all devices before connecting.

It is worth noting that troubles of such a plan can appear both with the TV port and with the laptop connector. To find out exactly where the problem lies, connect another gadget using HDMI. If you find a problem with one of the devices, it is best to seek professional help.
