Using a TV as a computer monitor is a smart choice, thanks to new TVs boasting major advancements in resolution and input lag. And it’s especially helpful as powerful new laptops emerge as true PC replacements.

The best way to use a TV as a computer monitor is by casting wirelessly. Streaming devices like Roku, Google Chromecast, Apple TV, and others let you share your computer’s display output with any screen you like. There are a few key considerations to check first, however, to make the switch frustration-free.

Can you use a TV as a computer monitor?

You can definitely use a TV as a computer monitor, though even two years ago we would have said to pump the brakes. What’s changed? Today’s TVs pack more pixels into less screen-space and respond faster to inputs from a mouse or trackpad than in the past.

Another game changer in using a TV as a computer monitor is casting. Devices like Google Chromecast or Miracast can turn your living room into an at-will home office. Just drop on the couch with your laptop and cast away.

Why use a TV as a monitor?

In the digital dark ages, using a TV as a computer monitor wasn’t practical. Computers had their own rooms with dedicated desks, peripherals, and a squid-like mass of dusty wiring. Even with powerful new PC-replacement laptops like the HP OMEN 17 or HP Spectre x360, computing has been slow to break its deskbound shackles. No more.

Today’s much larger TVs with sky-high resolutions and vivid colors signal a welcome end to the days of the “computer room.” We’re free to save the spare room for Aunt Edna, and relax on the couch with a lap desk while we work or game in style.

There are a few things to consider first, though, such as PPI, lag time, streaming devices, and knowing the best TV to use as a monitor. Once you grasp the top-line facts, you’ll settle the computer monitor-or-TV debate for good.

Check your PPI

What’s PPI and why should you care? It sounds techy, but it’s just “Pixels Per Inch.” A 4K phone is about 4,000 pixels wide. A 4K TV has the same number of pixels spread more thinly over a much bigger area. That matters when using a TV as a monitor because some older TVs don’t have great PPI scores. With a sparse pixel count, your documents and web pages can look a little fuzzy.

Two years ago, low PPI was the best argument against using a TV as a computer monitor. But most new TVs in 2019 have PPI scores of 80 or above. So how do you find out your TV’s PPI? Check the manual or do a Google search for the model number and “PPI.” You can also use Noteloop’s Pixel Density chart to get a rough idea [1].

Check your lag time

Serious gamers care about delay between controller or mouse commands and on-screen actions. It’s called “input lag.” Before using a TV as a computer monitor, ask yourself if you care about it. If your answer is “yes,” find your TV’s input lag online through a database [2,3] or simply Google “input lag” and your TV’s model number.

If you’re shopping for a new TV to use as a computer monitor, pick one with low input lag. The good news about today’s new TVs is that most of them slash lag times to be quicker. Most of us can’t detect lag times of less than 40 milliseconds (ms), and there are dozens of great sets for sale with lag times in the 5-15 ms range [4,5]. Either way, all but the most serious gamers won’t be bothered by longer lag times.

How to use a TV as a monitor wirelessly

The best part of using a smart TV as a computer monitor in 2019 is the lack of cables. If you’ve always wished connector cables would vanish and leave your floors free of tripping hazards, your wish is granted. Chromecast, Roku, and other casting or streaming devices solve the TV-as-computer-monitor problem in Tony Stark levels of style.

The first step is to pick a streaming device. You can choose from several, including Google Chromecast and Roku. They are flash drive style sticks or dongles that plug into a TV’s HDMI port.

Pro tip: All the major streaming units come in 3K and 4K models. It’s vital to get the 4K version. The 3K units work fine for video, but not when using a TV as a computer monitor. A 3K streaming unit will cause a bottleneck and scuttle the image quality.

Once you’ve settled on a casting device, plug it into your TV’s HDMI port. There’s a short configuration process, but anyone who can install an app can get it done in minutes.

Use a wired setup for very new TVs or old computers

Sometimes, a wired setup is better when using a TV as a computer monitor. If you’ve got an 8K TV or an older computer, you may want to skip the screen casting and revert to the spaghetti pile of wiring.

First, you need to think twice about using an 8K TV as a computer monitor wirelessly. You paid top dollar for that extra resolution, but Chromecast, Roku, and other streaming devices will waste it. An 8K screen places 8,000 pixels across your monitor, but TV-casting devices won’t deliver anything past 4K.

To get the best benefit from using an 8K TV as a computer monitor, go back to the old wired setup.

Older TVs and computers

If you’re using an older HDTV as a computer monitor, you may suffer from some fuzziness and longer lag time. If that doesn’t scare you, use Miracast or another streaming tech to share your computer’s display wirelessly to your TV. Are you wondering, “Can I use a TV as a computer monitor with an old TV?” You can, but you may need a VGA-to-HDMI adapter.

If your computer is the weak link because it’s not compatible with casting, you’ll need to use the wired method. Do that by plugging a DVI-to-HDMI cable into your PC’s DVI port. That said, the best TV to use as a computer monitor will always be a newer, high-res unit like an 8K set. If you don’t have $5,000 to shell out for a TV just now, stick with using a 4K TV as your computer monitor. In most cases you should save that standard HDTV for Netflix or Prime Video.

A warning about eye strain

Using a TV as a computer may cause eye strain, but it all depends. For best eye health, the Mayo Clinic says TVs and monitors should be at or just below eye-level [6]. A TV high on a wall could cause eye strain after several hours of daily use. Also, using a curved 4K TV as a computer monitor could hurt your eyes [7]. Aside from that, the greater the distance from your eyes, the healthier when using TVs as computer monitors.

Can you use a computer monitor as a TV?

Using a computer monitor as a TV is easy. Because computer monitors are generally smaller, they pack more pixels into less real estate, which makes their resolution better.

Key points to remember

Using a TV as a computer monitor is easier than ever thanks to today’s high resolutions and low input lags. To do it right:

1. Check your TV’s Pixels Per Inch (PPI) and input lag time. A PPI score of 80+ is best. You’ll want an input time of 40 ms or less.

2. If you have an 8K TV, use it as a monitor with a wired setup to preserve its sharper resolution.

3. Got a 4K TV? Ditch the wires and stream via Chromecast, Roku, Amazon Fire Stick, or other streaming tech.

4. Got an older HDTV? Using a standard HDTV as a computer monitor still works, though you’ll face some fuzziness and lag time.

Can You Use A TV As A Computer Monitor?

You can connect your computer to the monitor through HDMI, VGA, or DP ports. So, if your TV has one of these ports, you can easily use it as a computer monitor.

However, there are a few factors that determine if it is a good option for you. For instance, replacing your monitor with TV is generally preferred if you wish to watch movies and stream content from your PC. But, it can be problematic to play games and do graphic designing jobs unless your TV has a higher refresh rate and response time.

Things to Consider Before Using TV as a Computer Monitor

There are a few factors you need to consider that will help you decide whether to use a TV as a computer monitor or not. Let’s discuss some of the vital factors in brief.

Portability of TV

When it comes to portability, monitors are far more portable than TVs. You can adjust the computer monitors easily with respect to your viewing position and distance. But, the size and dimensions of the TV make it difficult to change its position. However, you can use VESA mounting adapters to adjust the position of your TV easily.

Likewise, as the TVs have a larger screen size, you need to sit at a distance from them. If you position yourself too near the TV screen, it can result in eye strain.

Therefore, if you are not among the ones who frequently need to adjust the monitor position, you can use TVs as a monitor.

Pixel Density Issues

Pixel density means the number of pixels per inch (PPI) on the display panel. TVs have a lower PPI than monitors, which makes the images on the TV screen blurry and fuzzy while you watch it from a distance.

Let us take an example. The number of pixels in a full HD monitor is 1920×1080. And it is the same for a full HD TV. And let the monitor size be 24” and the TV is 43”. So, when we divide the number of pixels by the size of the display panel, we get a higher PPI in monitors while a lower PPI in TVs.

Fewer pixels per inch means the image quality will degrade drastically. Therefore, a TV with a PPI value of more than 90 is preferred if you are into graphic-intensive tasks.

Resolution Mismatch Issues

When you view the contents of your PC on a TV, chances are there that the resolution set in the PC does not match the TV’s resolution. In such cases, the images do not appear crisp like on the monitor.

It mostly happens when your PC works over a built-in GPU. So getting a dedicated graphics card for your PC would be better. After that, you should know how to make a computer fit the TV screen.

Color Precision

Since TVs aim to provide a cinematic experience more than editing and gaming, the colors you see on the TV screen and monitor can vary widely. The color precision on the computer monitor is far more realistic than on the TVs.

Therefore, if you are into watching movies and surfing the Internet only, you can choose TVs over monitors. But we don’t recommend using TVs for graphic processing tasks like photo and video editing.

Input Delays

Input delay is the next important factor you should consider if you are planning to play games or image processing tasks on your TV. An input lag of 15 ms is generally good for gaming. But to your dismay, the TVs have a higher input lag. As a result, the commands you give the TV during gameplay can lag, ultimately degrading your gaming experience.

To overcome this issue, TVs do have a dedicated gaming mode. You can activate the gaming mode to reduce the input lags. However, if your TV does not have a gaming mode, you can turn off some graphic post-processing functions like motion blur and noise reduction. It will help reduce input delays.

Refresh Rate of TV

Refresh rate is the rate at which the display panel recreates an image on the screen. Typically, TVs have a refresh rate of 60Hz, meaning the images on your TV are refreshed 60 times per second. Meanwhile, typical monitors have a higher refresh rate of 90 Hz to 144 Hz.

The more the refresh rate, the more responsiveness, and smoothness you feel in the display. It helps decrease the motion blur as well. Not only that, a higher refresh rate helps to reduce eye strain. But since the TVs have a low refresh rate value, you can have problems working on them for a long time.

How to Use a TV as a Computer Monitor?

Now that you have decided whether to use the TV as a computer monitor or not, let’s see how to do it.

As mentioned already, you can either use VGA, HDMI, or DP cables to connect your computer system to the TV. First, check the ports available on your TV and PC and get a cable accordingly. Then, simply connect the two ends of the cable to the respective ports on the TV and PC.

After that, you need to change the source on the TV. Let’s see how to change the input source on Samsung 4 Series TV.

  1. Locate the Source button on your Samsung TV remote and press it.
  2. Choose HDMI if you are using HDMI cables to connect the monitor.
  3. You will now start seeing your PC screen on the TV.

TV instead of monitor for computer


  • 1 Which is better monitor or TV
  • 2 Screen type selection
  • 3 Connecting TV to computer
    • 3.1 Via HDMI or Displayport
    • 3 .2 Via DVI and VGA
    • 3.3 Via Wi -Fi
    • 3.4 Local area network

Using a TV instead of a computer monitor allows you to watch movies, series, and play video games on a large screen. The advantages are obvious – maximum image detail, an impressive TV diagonal, a wide range of colors. However, how exactly to connect the TV to the PC? Not all users know this. Therefore, now we will consider several proven methods that allow you to set up such synchronization.

Which is better monitor or TV? To answer this question, you need to clearly formulate the criteria for evaluating a computer monitor and TV. The first criterion is convenience. Immediately, we note that monitors in this aspect are much better.

This point of view is explained by several arguments:

  • it is impossible to adjust the height or angle of the TV. Because of this, there are certain inconveniences. This drawback can be leveled by placing the TV on the wall on a universal bracket. However, such a design will take up an extremely large amount of space. Not all users have the necessary free space in the room;
  • The

  • TV is much heavier than a monitor and takes up much more space. Therefore, if you have a miniature computer desk, then placing a 40-inch TV on it will be very problematic.

If we are talking about the correct position, then the distance from the computer screen to the user should be approximately 50 cm. If a TV with a diagonal of 30 inches and above is used, then the distance should increase. Otherwise, the user will not be able to view the entire plane of the display.

Dynamic scenes create additional eye strain. Therefore, it is desirable to increase the distance. In terms of technical characteristics: color palette, functionality, resolution, refresh rate, TV dominates.

The best option is to purchase a TV with a diagonal of 26-27 inches. Screen resolution should be in the range of 1920×1080-2560×1440 pixels.

Selection of screen type

To date, manufacturers use only two display technologies – liquid crystals and plasma panels. The latter option is gradually losing relevance due to the insignificant operational period. Therefore, LCD displays are the first choice for all users.

Using a Plasma TV as a PC monitor is not the smartest choice. Liquid crystal matrices are able to provide a higher screen resolution, which manifests itself in image quality.

Of course, you can think of TV with a CRT tube, but they are long gone. Therefore, it makes sense to focus on liquid crystal models. Analyzing the pros and cons of all types of screens, it must be said that the production of laser TVs is gradually increasing. However, this is still an experimental technology. The effect of laser displays on human vision has not been 100% studied.

Liquid crystal technology also has several subtypes. Mainly changes the specifics of the backlight. Each manufacturer supplies its products with branded “chips”. For example, Samsung TVs are primarily Super AMOLED. What is the best option to choose? It is impossible to answer this question without context. You need to know what the budget of the purchase is, for what purposes the TV is being purchased, etc.

Connecting a TV to a computer

There are several ways. Conventionally, all available methods can be divided into two categories:

  • wireless – creating a local network, direct connection via Wi-Fi, using special adapters;
  • wired – connecting a TV to a computer using a cable and available interfaces: HDMI, VGA, DVI.

Important! Not all interfaces are capable of simultaneously transmitting audio and video. Therefore, some users have to use additional wires to play the audio signal.

How to connect TV to PC? Each of the available options has its strengths and weaknesses. The final choice should be made in accordance with the available interfaces and functionality of the TV. For example, if the used model does not support Wi-Fi, but is equipped with an HDMI interface, then it is definitely worth using it.

Via HDMI or Displayport

The HDMI interface was designed for use in consumer electronics. This connector is used to connect game consoles, players, projectors and other equipment. The main feature of the interface in question is that it transmits a high-quality video signal and clear sound at the same time.

Displayport was invented by VESA. This input is intended to improve, not become an analogue of HDMI. It is Displayport that can be called the final interface for connecting equipment to a computer.

Many manufacturers for some reason do not equip laptops and PCs with a Displayport connector, which is a negative point. Preference is given exclusively to HDMI. Today, such a port can be found on all types of modern technology. Although Displayport functionality is somewhat better. Especially worth noting is the extensive package of options that will be of interest to business users.

If you want to use a laptop with a separate screen, then it makes sense to pay a little extra to buy a model with Displayport support. As a result, the user will get more flexibility that HDMI is not able to provide.

Instructions for connecting a TV to a computer via HDMI:

  1. Insert one cable plug into the computer connector, and the second into the TV port.
  2. Take the remote control, and press the button “Input” , and then select the main signal source “HDMI” .
  3. The TV screen will begin to flicker slightly, and after a few seconds the computer desktop will appear.

It is possible that after the first connection, the picture displayed on the large screen will not be displayed correctly. The problem can be easily fixed by performing appropriate PC settings. Right-click on an empty space on your desktop. From the drop-down context menu, select item “Properties” . Switch to tab Options .

Press button “Advanced” . Set the appropriate resolution for your TV. The image will display correctly. The essence of setting up a Samsung TV or a device from any other manufacturer is that the user sets the highest screen resolution.

What should I do if, after connecting, the TV is not detected automatically? You must press button “Find” . Wait for the search to complete. Set the screen to the largest value. to do this, switch to the tab “Monitor” , and then select “Frequent screen refresh” .

In section “Setting screens” each can be assigned a serial number. 1 is primary and 2 is optional. Click on the button “Define” . The number 1 will appear on the TV screen, and 2 on the computer monitor. To make changes, you need in section “Screen resolution” , click on the second screen, and then check the box next to the “Make the main monitor” field. When all this is done, be sure to save your changes.

To make the most flexible settings, you need to open the properties of the video card, and then set the desktop resolution and perform color correction. Be sure to restart your PC for the changes to take effect.

What should I do if the TV does not play sound? The problem is solved by performing a system configuration. You must select the TV as the default playback device. Instruction:

  1. Right-click on the speaker-shaped icon located at the bottom right of the screen – the notification panel. Select item “Playback devices” .
  2. The window that opens will display a list of connected devices, for example, “Speakers” and “LG TV” .
  3. Right click on the name of your TV. Select command “Use as default” . Press “OK” for all changes to take effect.

This is all you need to know about connecting your TV to your computer using HDMI.

Using DVI and VGA

Practice shows that all TVs and PCs are equipped with one of these interfaces. If you compare them, it is better to give preference to DVI. The VGA connector is considered quite outdated, so it is used only in the most extreme cases. Let’s imagine that you decide to set up synchronization via VGA. However, the monitor is turned on through the only free connector. What to do?

You can purchase a special adapter – DVI to VGA. This adapter allows you to transform the video card connector into an additional VGA input. Remember that only video signal transmission is carried out through the interfaces in question. Therefore, in addition to the DVI or VGA cable, you must use a special audio cable, at both ends of which there are 3.5 plugs.

3. 5 plug – a standard connector used in classic computer audio systems: headphones, speakers, etc. You shouldn’t have any problems purchasing this cable. Cords are available for purchase at computer and electronics stores.

Connection instructions:

  1. Insert the cable plugs into the corresponding connectors on the computer and TV. Connection scheme – DVI-DVI or VGA-VGA (depending on connection type).
  2. Insert the plug into the TV’s audio output. The interface is labeled “Audio-In”. Use a dedicated audio cable.
  3. Turn on PC and TV. Set your TV as the main input source to VGA or DVI. To enter the signal source selection menu, press the “Input” button on the remote control.

To use the TV as a computer monitor, it is necessary to extend the desktop. The algorithm for performing this procedure will depend on the operating system used:

  • Windows XP – right-click on an empty desktop space. From the context menu, select “Properties”, and then go to the “Settings” tab. You must select the largest screen resolution;
  • Windows 7 – right-click on an empty space on the desktop, and then select “Screen Resolution” from the context menu.

When the screen resolution is set, content can be played.

Via Wi-Fi

Smart-TV models are equipped with a hardware module for wireless Internet connection. Therefore, the easiest way is to connect your PC and TV to your home Wi-Fi network. For this you need a router. Some models are not designed for wireless internet connection. The problem is solved by purchasing a special adapter. You can also set up synchronization between TV and PC without a router.

Wireless synchronization is carried out using one of two technologies – Miracast and Intel WiDi. The advantage of this connection is that the user does not need a router. If you are using a laptop with a 3rd generation or older Intel CPU, built-in Wi-Fi module and graphics chipset from this manufacturer, then the laptop supports WiDi technology. It is important that an operating system older than Windows 7 is installed on the PC. To set up synchronization with a modern TV, download the Intel Wireless Display utility to your computer.

Laptops that are sold with Windows 8.1 pre-installed usually always support Miracast. It is important that the TV also supports wireless technology. Modern models come with built-in Miracast support. An alternative way is to purchase a special adapter.

Connection diagram:

  1. Wireless synchronization technology must be activated on the TV – Miracast or WiDi. Practice shows that this option is enabled by default. On TVs from Samsung, the function in question will be called “Screen Mirroring” .
  2. To connect equipment via WiDi, you must first download the Intel Wirelles Display software to your computer. Look for command “Wireless Monitor” . During the connection, a security check will be carried out, you need to enter the code that will appear on the TV screen.

To use Miracast, open the Charms panel in Windows 8.1. Move the cursor to the lower right corner, after that it will appear on the screen. Select “Devices” and then “Projector”. Click on Add a Wireless Display. If this command is not available, then your TV does not support Miracast technology.


Via LAN, the screen is configured using special software. The user needs to download and configure the DLNA server. There is plenty of good quality software available for free. For example, the Home Media Server program. Let’s use it as an example.

Once the software has been installed on the computer, certain settings must be changed. The TV must be connected to the PC with a LAN cable. turn off the TV first. Instructions for setting up a local connection:

  1. Start the software.
  2. Go to “Settings” , and then select the section “Devices” .
  3. Press the button “Search” .
  4. When scanning is completed, a list of available devices will appear on the screen.
  5. Select a TV by confirming the connection to the media server.
  6. Open item “Settings” again to select “media resources” .
  7. Press button “Add” , specifying the hard disk folders that will be shared with the TV.
  8. At the bottom of the window there is a folder “My Computer” , you can immediately select all the local drives of the hard drive.
  9. Now the entire PC file system will be available for viewing from the TV, press “OK” to start scanning.
  10. Open the media server by clicking on the button “Launch” in the main menu of the program.

Synchronization setup completed. Now let’s analyze the features of playing content on a TV, which is stored on a PC hard drive. Turn on the equipment, and then open program 9 on the computer0092 “Home media server” . Start the media server by pressing the Start button .

An Internet cable has already been connected to the TV via the LAN connector. Open the source list to select “LAN” . The menu is opened by pressing the button “Source ” or “Input” on the remote control. The explorer will start, using the remote control, switch between folders and play the necessary content.

Setting up the TV to be used as a computer monitor is not the most difficult process. To achieve the result, you just need to follow the instructions described above. The choice of connection method is carried out in accordance with the functionality of the equipment.

Using TV as a monitor for a computer

Today’s TV technology works great in tandem with other modern devices, including PCs. You can safely use the TV as a computer monitor. It remains only to figure out how to connect and configure it correctly. Many beginners have serious problems with this procedure.

Synchronization features

Such a tandem has its pros and cons. Among the obvious advantages, first of all, we can single out screen diagonal . For average monitors, this figure ranges from 17-24 inches, while for TVs it is around 30-40 inches.

Enjoy multimedia content, documents and games on a big screen TV. But there are downsides to this approach as well. TV equipment in a good half of the cases is devoid of any adjustments, that is, it is static – it’s set and that’s it. While the position of the monitor can be changed – vertically and / or horizontally.

Important! If you make a monitor out of a TV, you will have to think about this issue: mount the bracket on the wall or organize some other devices to adjust the angle of inclination.

In addition, a TV is much heavier than a computer monitor, as well as overall. Using the TV as a monitor requires more desktop space . A device with a diagonal of 30 inches must be located more than 50 cm from the user’s eyes, otherwise he will not be able to see everything that happens on the screen. Not all computer desks fall under these criteria.

There are two ways to connect equipment – via cable and via wireless protocols. Let’s analyze them in more detail.


This is the most stable and easiest option. It does not require any specific settings and works great in the “as is” format. There are several ways to connect a TV to a computer instead of a monitor: via DVI, VGA, HDMI, or DisplayPort.

HDMI / DisplayPort

HDMI interface is used to connect media players, game consoles and other equipment. The HDMI port can transmit a high-quality, high-definition video signal, along with an audio track, and with an almost perfect response.

DisplayPort is the next generation of interfaces developed by VESA. To connect to the system unit, this is an ideal option that meets all modern technological trends. Both interfaces are quite common, especially HDMI. DisplayPort is found only on new technology, so not every TV can be connected to a laptop or PC video card.

How to connect TV to PC via HDMI or DisplayPort:

  1. We insert the plug into the TV on one side and into the video output on the PC on the other side (video card, laptop port).
  2. Call the technical menu on the remote control by pressing the Input key (a similar action can be performed through the TV settings).
  3. Select HDMI or DisplayPort as the main signal source.
  4. The technician needs a few seconds to accept the connection, after which the PC screen will switch to the TV screen.

Sometimes it may take longer to synchronize. It depends on the firmware of the TV and the video card of the computer. If the picture is not displayed correctly, then you should adjust the settings on the PC.

Image debugging on PC:

  1. Open the context menu by right-clicking on the desktop.
  2. Select “Display Options”.
  3. In the “Multiple displays” section, set the native resolution of the TV.

Here in the additional parameters you can adjust screen refresh rate and set other presets. If the TV is not defined as a second monitor, then you need to press the “Detect” button.


Ports have long lost their relevance, and you can meet them on old equipment. VGA-interface broadcasts only analog signal, while DVI-port can also work with digital broadcasting . The corresponding prefix indicates the possibilities of the latter:

  • DVI-I – universal option;
  • DVI-D – digital broadcast only;
  • DVI-A – analog only.

If your TV has a DVI port and your computer has a VGA port, or vice versa, you can use the adapter .

Important! It should be clarified here that only the video signal is transmitted in this way. To transmit audio, you must additionally connect another 3.5 mm mini-jack cable.

TV to PC connection via DVI / VGA:

  1. Insert the video plugs into the corresponding interfaces.
  2. Connect the audio cable to the Audio-In port.
  3. In the TV menu, set DVI or VGA (sometimes D-Sub) as the signal source.

If necessary, adjust the image on the PC according to the instructions above.

Sound problems

When connecting a TV as a monitor, sound may sometimes not be produced. Here you also need to perform a series of actions on a personal computer.

Sound setting:

  1. Right click on the speaker icon at the bottom of the interface.
  2. We find the item “Playback devices”.
  3. In addition to the PC speakers, the list must include the TV model.
  4. Select TV with the right mouse button and click on “Set as default”.
  5. Save the changes by clicking the OK button.

Wireless connection

You can also connect your phone to the TV via WiFi or LAN via DLNA server. The ideal option is to adopt Miracast or WiDi technology ( Wireless Display): there is no fundamental difference between them. For the latter to work correctly, you need a Smart TV and a PC running Windows 8 or higher. The equipment must be connected to the same Wi-Fi network.

Connecting TV to PC via Miracast or WiDi:

  1. Open the “Network” item in the TV settings.
  2. Click on the line Miracast / Intel’s WiDi.
  3. Move the slider to the on position.
  4. Download and install the Intel Wireless Display drivers (freely available) on the PC.
  5. In the utility settings, select “Devices” and “Detect”.
  6. Click on the TV model and wait for the synchronization to finish.

You can connect your TV to your computer via a DLNA server. There are more than enough special utilities for organizing the latter on the Web. The program “Home Media Server” has proven itself especially well . Consider synchronization on its example.

Connecting TV to PC via DLNA server:

  1. Install the utility on the PC.
  2. We go into the settings and click on the “Devices” item.
  3. We start searching for equipment for synchronization.
  4. Select a TV model from the list that appears.
  5. Go to the Media Resources section.
  6. Click on the “Add” button and designate all the disks or individual folders that will be given access to the TV.
  7. Save the changes by clicking “Apply”.
  8. On the main screen of the program, open the appeared media server and click on the “Start” button.
  9. On the TV, select the LAN protocol as the signal source, after connecting the cable from the TV to the corresponding connector on the PC.
  10. Now all playable content on PC from the above discs or folders will be broadcast on TV.

Wireless Disadvantages

Despite the convenience of wireless protocols, they also have serious disadvantages. When working with the above technologies, braking and freezing are often observed. In addition, the quality of the output image does not always meet the stated requirements. Unpleasant “soap” or artifacts may appear.

Tip! If we are talking about the gaming side of the issue, where a good screen response and normal visualization of dynamic scenes are needed, then it is better to stay on a wired connection. In other cases (movies, music, web surfing) you can close your eyes to these shortcomings.
