Determine available connections
To transfer an image from a laptop to a TV, you need to find out what methods are available for this. First, you should see what ports are present on the TV and laptop, and then decide how best to duplicate the laptop screen.
ways to transfer an image from a computer to a TV screen
The laptop is very convenient for work with its dimensions and low weight. But when it comes to watching videos or playing games, you want to replace a small monitor with a larger screen. If you have a TV with a large diagonal, you can connect your device to a TV or home theater. In the article, we will consider how you can display an image from a laptop on a TV.
S-Video is an analog interface. It can only transmit video files of standard definition television (576i and 480i), which means that modern speech quality formats are out of the question. TVs are rarely equipped with such a port, therefore, in order to project an image from a laptop, an S-Video to RCA adapter is additionally required. Also, do not use an S-Video cable longer than 2 meters, as this will degrade the signal quality. To transfer audio to TV, similar to DVI, you will need to use a “minijack”.
After connecting the cable, you always need to install the video source on the TV
Let’s look at how you can output an image to a TV via USB. In this case, when connecting USB-USB, it will be impossible to view video, since this standard is not designed to transfer video data. In this option, you can view images, presentations, text documents. With this connection, the TV will see the laptop as a USB flash drive.

But to duplicate the laptop display, you can use the output to the TV’s HDMI port. To do this, you need an adapter, which is an external video card. You will need to install the driver from the video card to the laptop. When purchasing such an adapter, you should pay attention to the characteristics of the transmitted video (Full HD support) and sound.
We have already examined the connection using a local network wirelessly. Lan is a network but wired (Ethernet) connection. If the TV does not have a Wi-Fi module, then you can use this method. To mirror the computer screen to the TV, you will need to follow the same steps as for the WI – FI connection. Namely:
- Connect TV to the router using a network cable. In this case, the Dynamic Host Configuration Protocol (DHCP) must be configured on the network device. Otherwise, you will have to manually register the network settings in TV;
- Connect your laptop to the same network. Wired or wireless. it doesn’t matter;
- Install the program on the laptop to output files to TV. We’ve already covered the Home Media Server application, which is easy to set up and install;
- Share the required folders. That’s it, now you can transfer images and send video for playback.
How is it possible to transfer an image from a computer to a TV using VGA? The VGA standard only allows the transmission of an analog signal without sound. To reproduce sound, you will need an additional adapter with the so-called “tulips” or “minijack” plug. Another option is to leave the sound playing on the laptop or through the speakers connected to it. To do this, you can use the function keys of the laptop. It should display 2 screens, for example, F10Fn (function enable key). It is now possible to display videos from a laptop on a TV. When setting up display on a laptop, you can increase the resolution to get a better picture.
With any cable connection, you will have to adjust the screens on a laptop or PC
The color image is formed by means of three main signals: Red, Green, Blue. If the image is output from such a connector, then it is logical to use the same TV input. RGB replaced Scart when Scart became impossible to use in thin TVs. Mostly RGB is available on older models. Compatible with Scart and composite RCA (tulip) cables. Videos or games from the computer monitor to the TV will be broadcasted as with any other cable connection.
Ways of displaying images from a laptop to TV
There are wireless and wired methods for displaying images from a laptop to a TV. With a wired connection, you do not need to have the same ports on both devices. If they are different, then you will need to use adapters. If you need to translate digital data to an analog input, you will need additional converters or attachments.
The disadvantages of a wireless connection are limited bandwidth and possible signal interruption. The disadvantage of connecting via a cord may be the presence of the cord itself, as well as the cable length limit for different standards. However, if you need to connect a laptop and enjoy viewing, this drawback is completely weightless and will not cause inconvenience.
All modern TVs are equipped with DLNA technology, which allows devices to exchange data within the home network. This can be done both via cable and WI-FI. If there is a connection via WI-FI, then both the laptop and TV must be connected to it. But the TV will only “see” the shared folders. In order for the TV to have access to all the information, you can open shared access to all folders in the “Network” settings on the laptop. But this is not recommended for security reasons. After all, in this case, everyone who will be connected to your network will be able to use your data. Another option is to make a specific folder publicly available.
But for a more convenient display of the image on the TV, it is better to download the program. One of the recommended ones is Home Media Server. It is free and universal for different TV models, and also has wide functionality. To install on a laptop, just download the application (preferably on the official website) and run the installation file. After starting the program, in the settings window, you can select the category of media resources and already specify access to the folders there.
If your devices support Miracast or Intel WiDi technologies, then it is enough to enable these functions on the TV. Then he will be able to connect wirelessly to your laptop without a router, directly. On the laptop, however, you need to install the appropriate application. But when connected, you can display any picture from a laptop.
If the TV does not have a WI-FI module, then you can use various adapters that can be connected to the HDMI port. For example, one such device is the Google Chromecast, which looks like a USB flash drive. The gadget is designed for streaming multimedia content.
The connection via HDMI can be called optimal in order to transfer media data from one equipment to another. This standard provides high-speed transmission, even of ultra HD-quality files, and transmits not only video, but also multichannel audio.
How to output images from a computer to a TV using HDMI? It is enough to connect the two devices with a cable. Then switch to TV AVI mode and select the port to which the cord is connected. On a laptop, you need to call the screen settings and set the required resolution there, as well as select the display of displays. This means that on a laptop you will be able to control both screens, and you will need to select a display for the TV screen. The options are:
- Duplications. the same image on both screens;
- Display on 1 screen. the second one will be turned off;
- Screen Enhancements. TV will become a second monitor.
Settings may vary depending on the version of the operating system.
For any wired connection, the devices must be disconnected before connecting them
The next way is how to transfer the image via DVI. The DVI standard was developed for transferring video content to digital devices. Predecessor to HDMI. And, unlike the latter, it does not transmit sound. In this case, you will need a TRS connector or adapter, otherwise called “minijack”. a very popular audio connector, probably familiar to many as an input for connecting headphones. To duplicate the screen of a computer or laptop, you will need to follow the same steps as for HDMI. Once connected, transferring the playing file is easy.
Scart is a European standard for transmitting analog and digital signals. It has different specifications, therefore, it can transmit different signals (audio channel, video, control). The convenience of the interface is that it makes it possible to connect a high-quality RGB video source to the TV without intermediate coding.
To broadcast a movie from a PC or laptop, it is better to use a VGA-SCART adapter. This is due to the fact that a large number of TVs are equipped with a SCART connector, and computers. VGA.
If you have a large number of connectors, it is better to choose a wired connection from the latest technologies. The best option is HDMI. In general, setting up your laptop and TV is straightforward. The main thing is to select the input signal on the TV, and on the laptop perform the settings that are required for the corresponding technology.
How to open media stored on your computer using the TV app
You can open media stored on your computer using the TV app, but you need to enable sharing.
Next, go to the “All networks” tab, mark all the buttons that are on permission and find the “Select streaming options” tab
Next, check the boxes for permissions
You also need to enable in the parameters “Network and Internet Wi-Fi” “Additional parameters” download via metered connection.

How to display picture or video from phone to LG TV
Modern gadgets and home appliances have long become complementary devices due to their ability to connect to the Internet and synchronize. And this is very convenient, as it allows you to expand the functionality and make the use easier and more convenient. For example, you can control your LG Smart TV with your smartphone (turning it into a remote control) or display images and videos from your smartphone on your TV screen.
What is it for? Pros of connecting a smartphone to an LG TV:
There are many benefits to syncing your smartphone. And here are the main ones:
- You can watch photos and videos from the “Gallery” of your smartphone on a large TV screen in high quality.

- It is very convenient to browse various sites, as well as read documents and view presentations.
How to connect a smartphone to an LG TV: step by step instructions
Displaying images and videos from a smartphone to an LG TV is possible in several ways, both using a cable and using wireless networks.
Screen Share is a program specially designed to synchronize your phone and LG Smart TV and watch content on the big screen. The transfer of images and videos is carried out using
Miracast standard (Wi-Fi Direct technology). The connection can be made with 100% probability if you have an LG TV and a smartphone. Option may not be supported with smartphones from other manufacturers.
In order to start the synchronization process, you need:
- Press the Home button on your LG TV remote control.

Also, different models of smartphones can be connected to an LG TV using different connectors. For example, a number of LG phone models (including the LG 2X) are equipped with a dedicated Micro HDMI port or the more modern USB Type-C port. Also, a number of smartphones of democratic models support the MHL standard (Mobil High Definition Link), with the help of which the signal comes directly from the data transfer and Micro-USB charging port. MHL analog. SlimPort standard, implemented in many LG smartphones, allowing video transmission in 1080p resolution.
All of these methods are suitable for older models of smartphones. For newer models, it is recommended to prefer wireless data transfer methods.
Image on TV from laptop or smartphone via Wi-Fi
I noticed that many people want, for example, to launch an online movie on a tablet, in a browser and display it on the TV. But in order to broadcast a movie via DLNA, you must first download it. Not everyone likes this, and not everyone knows how to download movies on a tablet or smartphone. If you have a Smart TV, then you can watch online movies directly from your TV, and you do not need any additional devices for this. How to do this, read this article.
There are two main technologies that allow you to wirelessly duplicate everything that you see on the screen of your laptop or mobile device on a TV. These are Intel Wireless Display (Intel WiDi) technologies. and Miracast. Chances are, you’ve already heard about these technologies, or seen them in the settings of your devices.
If you explain their work in your own words, then everything happens like this: the image that is displayed on the screen of your computer or mobile device is compressed and transmitted via Wi-Fi to the TV. All this happens very quickly, and the delays are almost invisible.
You just turn on Miracast, or Intel WiDi on the TV (if it supports this technology, if not, then you need a special HDMI adapter). and on a mobile device, or on a laptop using a special program, start the broadcast. The devices are connected and the picture is transmitted to the TV. By the way, a Wi-Fi network (router) is not needed at all, the TV itself creates a network to which you just need to connect. Something like Wi-Fi Direct.
At first glance, everything is very simple. But, at the moment, not all devices support these wireless technologies. Although, I think that in a year, this will no longer be a problem.
By the way, Intel WiDi (starting from version 3.5) is compatible with Miracast. Therefore, the technology from Intel can be considered universal.
How to display an image on a TV from an Android tablet, or a phone using this technology, you can read in this article.
Intel WiDi and Miracast on TVs
We figured out the devices that will transmit the image over the air, now with regard to the TVs that will display this very image. The TV must either have built-in support for Intel WiDi / Miracast, or you will need to buy a special receiver that connects to the HDMI connector of your TV.
As far as I understand, almost all TVs of popular manufacturers: LG, Samsung, Toshiba. starting from the line of 2013, and which have support for Smart TV, have built-in receivers and are able to work with the Intel WiDi / Miracast standard.
If the TV does not have built-in support, then, as I already wrote, an external HDMI adapter will help. By the way, the image goes through it even better than through the built-in.
For example, the LG 32LN575U TV is an inexpensive model with the Smart TV function, there is support for Intel WiDi / Miracast. It looks like this:
Perhaps, somehow I will demonstrate the work of this technology, but this will already be in another article.
Which devices support Intel WiDi and Miracast?
As for computers (laptops). then Intel WiDi technology requires a 4th generation Intel processor, Intel graphics, and an Intel wireless Wi-Fi adapter. As you already understood, not every laptop can boast of such a configuration. Or, you need a special attachment.
If we talk about mobile devices, then they should also support Intel WiDi, or Miracast. If you plan to use these technologies, then see the characteristics of the devices and check the availability of these technologies before buying.
You can see detailed information on devices that support this technology on the official website http://www.intel.ua/content/www/ua/uk/architecture-and-technology/intel-wireless-display.html.
How to display an image from a laptop, smartphone, or tablet to a TV over Wi-Fi? TV as a wireless monitor [Intel WiDi and Miracast]
I very often have to answer questions that sound something like this: “Is it possible to use a TV as a wireless monitor for a laptop or smartphone?” “How to display an image on a TV from a tablet, computer, or phone, but not via cable, but via Wi-Fi?” “How to make it so that everything on a tablet or smartphone is displayed on the TV, and that everything is in the air?”.
In this article, I will try to answer the questions posed. We will figure out whether it is possible to display an image on a modern TV without a cable, and how to do it using Intel WiDi or Miracast technologies.
Before proceeding with the main part, in which I plan to tell you how you can still turn a TV into a wireless monitor, you need to understand something:
It can slow down by air, use a cable
If you want to display the picture on TV from your laptop, in order to play games, or watch movies, then it is best to do it via HDMI cable. There should be no problems with a computer, since now almost every laptop or every video card has HDMI, and even in TVs this is far from uncommon. How to connect all this, read the article How to connect a TV to a computer (laptop) using an HDMI cable? TV as a monitor.
No wireless technology will provide the picture quality you get with a digital HDMI cable (at least not yet). Yes, I want it without wires, but with wireless technology, there will be slowdowns, albeit not great. And it’s not very pleasant to play games, or watch movies with some kind of delays in the image.
You can display video and photos on TV without special technologies
In this article we are talking about dubbing absolutely everything that happens on the screen of your device to the TV.
But, in order to simply broadcast photos or videos from your computer, smartphone, or tablet to TV via Wi-Fi, no special technology is needed. Almost every modern TV supports DLNA technology (if there is a Smart TV, then it definitely does). Computers and mobile devices can also transfer media content using DLNA technology. Android can do it for sure, and iOS can do it too (if I’m not mistaken). and in Windows Phone, such an opportunity will appear after updating to version 8.1 (at the time of this writing, the official update will wait about a month).
To set up the broadcast of photos and films over the air from your computer to your TV, see these instructions:
If the first article is suitable only for LG TVs, then the second one can be called universal.
Well, if you still need to completely duplicate the picture on the TV, and even without wires, then read on.
Let’s summarize. If you want to use the TV as the main monitor or the second monitor for your computer or mobile device, and you do not have an urgent need to connect them over the air, then it is best to do it with a cable. It’s cheaper, and the quality of the picture will be better.
Do not forget that using DLNA technology, and via Wi-Fi, you can broadcast photos and videos to your TV. But you won’t be able to display the image by running the game while in the browser or on the desktop.
If you still want everything that is displayed on the screen of your computer, smartphone, or tablet to be displayed on the TV screen, then look towards Intel WiDi and Miracast technologies. If your devices do not support these standards, then you will have to buy special set-top boxes and receivers.
If you are just planning to buy new devices and are going to use these wireless technologies, then before buying, see if they support these standards.
I also recommend watching the video Review of Intel WiDi technology from Natasha.
How to connect speakers to your LG TV
Modern LG TVs boast high-quality sound. Nevertheless, many equipment owners want to further improve the audio system by connecting speakers to the TV. This allows you to enjoy the highest quality surround sound.
Before you start connecting speakers, you need to clarify what audio jacks your LG TV model is equipped with. The most common. digital HDMI-connector, line-in (MiniJack) or specialized acoustic SCART or RCA connectors.
LG TV models with Smart-TV have the ability to connect wireless speakers via Bluetooth.
HDMI. Found in most modern TVs and home theaters. Allows you to transfer information without loss of quality.
If you are going to connect a powerful audio center with built-in amplifiers to your TV, it is recommended to use HDMI connectors.
MiniJack, SCART (hairbrush) and RCA (tulip) are not designed for high-power audio systems. When using these connectors, you need to be especially careful, since if you connect speakers with a more permissible power to the TV, there is a risk of damage or even damage to the equipment.
The second thing to look out for is the speakers themselves. Acoustic systems are active and passive, and the connection method depends on their type.
Active speaker system assumes the presence of a built-in amplifier and is connected to the mains for power. In the overwhelming majority of cases, such speakers are connected to the TV using 3.5 mm inputs, designated MiniJack or TRS. In the event that your LG TV does not provide such connectors, you can solve the problems by purchasing an additional adapter “MiniJack / RCA”.
Passive speaker system is not equipped with an amplifier, it must be purchased separately and the speakers must be connected first to it, and only then through the amplifier to the TV. In this case, there is a possibility that the sound quality will not be optimal.
Here’s what to look for when choosing an amplifier:
- Its power should not be more than a third higher than the power of the speakers. (Carefully read the User’s Guide for the speakers, this information is sure to be there).
- The impedance of the amplifier and speakers must be equal.
- The wire with which the amplifier will be connected to the TV is very important. Experts recommend not to use a cord with a cross section of less than 2 mm.
How to connect speakers to a TV using wires: step by step instructions
- Having decided on the type of connector, connect the HDMI, RCA or MiniJack cable to the corresponding jack on the back of the TV.
- If you are connecting computer speakers to your TV, use your TV as a power source. To do this, plug them into any available USB port on the rear panel.
- Adjust the sound settings on your TV.
How to connect wireless speakers to your TV: step by step instructions
- Turn on the TV using the remote.
- In the “Menu” find the Bluetooth section and make sure that this option is active.
- In the list of available devices, find the Bluetooth speaker you want to connect.
- Sync your devices.
After you have successfully connected the speakers to your LG TV, you need to complete the process by adjusting the sound settings on the TV itself.
- In the menu, select “Home” (Icon “Home”).
- Go to the section “Settings” (Icon “Gear”).
- In the upper right corner, find the icon with three vertical dots, and in it the “Sound” section.
- In the subsection “Audio Out” select “Audio Out (Optical / HDMI ARC)”.
- Activate SIMPLINK mode.
If you are using a speaker that supports LG Sound Sync:
- In the menu, select the item “Home” (Icon “Home”).
- Go to the section “Settings” (Icon “Gear”).
- In the upper right corner, find the icon with three vertical dots, and in it the “Sound” section.
- In the subsection “Audio Out” select “LG Sound Sync (Optics)”.
If you are connecting an audio system that supports LG Sound Sync using Bluetooth, select “LG Sound Sync (Wireless)” in the settings.
