Modern televisions based on Android TV have turned into powerful multimedia centers that can replace a traditional monitor. The need to display images from a desktop or laptop on a large screen arises regularly: whether it’s watching movies, presenting a business project, or running demanding games. Fortunately, technological progress offers many solutions, from classic cables to advanced wireless protocols.
In this article we will analyze in detail all the available connection methods. You'll learn how to set wireless broadcasting lag-free, which cables will provide maximum 4K picture quality, and how to use built-in Windows features and third-party tools. Choosing the right method depends on your purpose: minimal latency is important for gaming, and connection stability is important for watching videos.
Before you start setting up, make sure that your devices are compatible. Most modern Smart TV support Miracast and Google Cast standards, which simplifies the process. However, older models or specific applications may require additional adapters or software. Let's look at each method in detail.
Wireless broadcasting via Miracast and Wi-Fi Direct
The most popular method that does not require the purchase of additional equipment is the use of technology Miracast. This standard allows you to stream high-definition video and audio directly between devices if they are on the same Wi-Fi network or connected via Wi-Fi Direct. In the Windows operating system, this function is often called “Connect to a wireless display.”
To get started, you need to activate signal reception on the TV itself. Depending on the manufacturer (Samsung, LG, Sony), the name of the function may differ: Screen Mirroring, Smart View or simply “Broadcast”. After activating standby mode on your TV, go to Windows settings. Press the key combination Win + Kto open the connection panel.
⚠️ Attention: When using the wireless method in busy Wi-Fi networks (offices, dormitories), picture instability or sound desynchronization may occur. For mission-critical presentations, it is better to use a wired connection.
The system will begin searching for available devices. As soon as your name Android TVappears in the list, click on it. A request to confirm the connection may appear on the TV screen - you need to accept it with the remote control. After successful pairing, the desktop image will be completely duplicated on the big screen.
Using built-in Chromecast in Android TV
Since we are considering devices based on Android TV, we cannot ignore native support for the technology Google Cast. Unlike Miracast, which simply mirrors the screen, Chromecast allows you to “cast” content from your browser or apps directly to your TV, freeing up computer resources. This is especially convenient for watching videos from websites.
To implement this method, you will need a browser Google Chrome on your computer. Open your browser and make sure your PC and TV are connected to the same Wi-Fi network. In the upper right corner, click on the three menu dots and select “Cast”. If you want to broadcast the entire system, select "Broadcast desktop" from the drop-down list.
The advantage of this method is stability and support for high resolutions, up to 4K HDRif network speed allows. In addition, playback control (pause, volume) is often available directly from the phone or tablet, which acts as a remote control. However, this method may not be suitable for games due to a higher input lag compared to a direct connection.
Why does the sound disappear when broadcasting via Chrome?
Sometimes the browser by default transmits only the video stream. In the broadcast settings menu (three dots in the preview window), make sure that the "Broadcast with sound" option is selected or check the Windows audio device settings by switching the output to the TV speakers.
Connect via HDMI cable for maximum quality
If you need the perfect picture without compression artifacts and minimal latency, there is no substitute for a physical connection. Cable HDMI remains the gold standard for connecting a PC to a TV. Modern versions of the cable, such as HDMI 2.0 and HDMI 2.1, are capable of transmitting a 4K signal at 60 Hz and even 120 Hz, which is critical for gamers.
The connection process is trivial: connect the computer’s video card and any free HDMI port on the TV with a cable. Then on the TV remote control, press the signal source button (usually indicated as SOURCE or a square icon with an arrow) and select the appropriate port. Windows will automatically detect the new display.
However, simply plugging in the cable may not be enough for it to work correctly. Often, manual adjustment of the resolution and refresh rate on the system is required. Go to Settings → System → Display → Advanced display settings. Here you can set your native resolution Android TVso that fonts and interfaces look sharp and not blurry.
Use HDMI cables marked "High Speed" or "Ultra High Speed" to support 4K and HDR. Cheap cables may be unstable over long distances or at high resolutions.
Third-party applications for advanced capabilities
Native Windows and Android tools are sometimes not enough, especially if you need to cast images to devices that do not support Miracast, or you need to transfer the screen from a smartphone to a PC, and then to a TV. This is where third-party software solutions come to the rescue, which are installed both on the computer and on the TV via Google Play Store.
One of the most popular solutions is a bunch of applications that work on the server-client principle. You install the receiver (Receiver) on the TV and the sender on the PC. Such apps often allow you not only to duplicate the screen, but also to control your computer using a TV remote control, use your smartphone as a touchpad, or even play games with gamepad emulation.
- 📱 AirPin (PRO) - a universal solution that emulates AirPlay and Miracast, great for Apple and Android devices.
- 💻 TeamViewer / AnyDesk - allow you to remotely control your PC from a TV, which is convenient for demonstrating files, but not for video due to delays.
- 🎮 Steam Link is an ideal application for gamers that allows you to stream games from a powerful PC to a TV over a local network with minimal latency.
When choosing an application, pay attention to the version requirements Android on your TV. Some modern applications may not work on older TV models with an OS version lower than 8.0. It is also worth considering that free versions of apps often have limitations on session time or picture quality.

Comparison of connection methods: characteristics table
To make it easier for you to choose the optimal method, we have prepared a comparison table. It will help you weigh the pros and cons of each method depending on your current tasks and available equipment.
| Method | Image quality | Latency | Required equipment |
|---|---|---|---|
| HDMI Cable | Maximum (Lossless) | Minimum (0 ms) | HDMI Cable |
| Miracast | High (compression) | Medium (depending on Wi-Fi) | Wi-Fi router |
| Chromecast | High (adaptive) | Medium/High | Wi-Fi router, Chrome Browser |
| Third-party Apps | Depends on the application | High (usually) | Installing software on both devices |
As can be seen from the table, it is perfect for static content or working with documents Miracast. If you plan to watch movies in high bitrate, it is better to choose Chromecast or cable. Gamers should focus exclusively on a wired connection or specialized streaming applications like Steam Link.
⚠️ Attention: Menu interfaces and item names may differ depending on the shell of the TV manufacturer (for example, MIUI TV, WebOS with Android applications or pure Android TV). Always check the official documentation for your model.
Setting up sound and resolving problems
Often, after successfully broadcasting an image, users are faced with a lack of sound. By default, Windows may continue to output audio through the laptop's built-in speakers or connected headphones. To fix this, you need to manually switch the output device.
Click on the speaker icon in the tray (lower right corner of the screen) and select yours in the list of playback devices Android TV. If the device is not displayed, check the video card drivers, since audio via HDMI is often transmitted by the video driver (NVIDIA, AMD, Intel). Updating the drivers may solve the problem.
Another common problem is side mismatch. The picture may be cut off at the edges or have black stripes. This can be solved by setting the scale in Windows (Settings → System → Display → Scale and Layout) or setting the screen format in the menu of the TV itself (often called "Just Scan", "Screen Fit" or "16:9").
Correctly setting the resolution and refresh rate in Windows is the key to a clear picture. Do not ignore this step, even if the image appeared immediately after connecting.
Frequently asked questions (FAQ)
Is it possible to broadcast the screen without a router, directly?
Yes, Wi-Fi Direct technology, which is the basis of Miracast, allows devices to connect directly, bypassing the router. However, both devices must support this function, and in some cases the TV must be placed in a special standby mode.
Why does the mouse cursor lag during broadcasting?
Cursor lag is a typical sign of an overloaded communication channel. This often happens when using wireless methods (Miracast, Chromecast) on networks with a lot of interference or when the Wi-Fi signal is low.
Does Android TV support 5.1 audio over HDMI?
Yes, if your TV and sound system (soundbar or receiver) support multi-channel audio and you use a high-quality HDMI cable. In Windows sound settings, you need to select the appropriate format (for example, Dolby Digital or DTS).
How to turn off the broadcast?
For wireless methods, just click Win + K and select "Disable", or use the disable button in the Chrome browser. For HDMI, just switch the signal source on your TV or turn off the monitor.
