Modern technologies make it easy to stream content from your computer to a large screen without the need for unnecessary wires. Wireless connection has become a standard of convenience, eliminating the need for users to run HDMI cables across the room. Owners of devices based on Windows 10 can use the built-in functions of the operating system to instantly start broadcasting.
The main advantage of this method is its versatility and support for most modern Smart TVYou won't need to buy expensive adapters or complicated converters if your TV supports the standard. MiracastThe setup process takes just a few minutes and doesn't require any advanced technical knowledge.
In this article, we'll cover all connection steps, potential issues, and solutions in detail. You'll learn how to set up screen projection, which network parameters are critical, and how to ensure stable, high-quality video transmission.
Technical requirements and equipment preparation
Before you begin setup, you need to make sure that your equipment meets the minimum requirements for wireless data transmission technology. The key condition The laptop must have a Wi-Fi module that supports the "Monitor" or "SoftAP" operating mode. Most modern models released after 2015 already have the necessary hardware support.
The second important element is the TV itself. It must be equipped with a module. Wi-Fi Direct or support Miracast technology. If you have an older Smart TV model, you may need to use an external adapter, such as Microsoft Wireless Display Adapter or analogs from other manufacturers.
⚠️ Important: Make sure Screen Mirroring or Anyview Cast is enabled on your TV. On some models, this is disabled by default and must be activated manually through the signal source menu.
The state of your software is also critical. Your wireless adapter drivers must be up to date, and your operating system Windows 10 — updated to the latest version. Older driver versions may not work correctly with new encryption protocols.
- 📶 A laptop with a working Wi-Fi module and support for the 802.11n/ac standard.
- 📺 Smart TV with Miracast, Wi-Fi Direct, or built-in DLNA receiver.
- 🔄 Up-to-date network card drivers and Windows 10 operating system (version 1607 or later).
- 🏠 A stable home Wi-Fi network (preferably 5 GHz band for 4K video transmission).
Checking network compatibility and settings
A successful connection depends directly on the local network configuration. Both devices must be on the same subnet. This means that the laptop and TV must be connected to the same routerIf you have a dual-band router, make sure both devices are using the same frequency, although modern routers often combine networks under a single name.
Windows 10 has a built-in diagnostic utility to check compatibility. It allows you to quickly determine whether your computer can serve as a wireless display source. Open Command Prompt or PowerShell and enter the command to check the Wi-Fi Direct status.
netsh wlan show driverIn the window that opens, look for the line "Hosted network supported." If it says "Yes," then basic support is available. However, for screencasting, support is more important. Wi-Fi Direct, which is checked through the projection parameters.
Don't forget to check your firewall settings. Sometimes antivirus software or Windows Defender can block your device from being detected on the network. Make sure your current network status is "Private" and not "Public."
Setting up your TV to receive a signal
The process of preparing your TV may differ depending on the manufacturer and the operating system installed (Tizen, WebOS, Android TV). In most cases, you need to go to the signal source menu (Input/Source) and select the option to connect to a mobile device or PC.
On Samsung TVs, this feature is often called "Screen Casting" or "Smart View." On LG devices, it may be hidden under the name "Screen Share." In the menu Android TV You need to find the "Cast" app or enable the Chromecast built-in feature.
⚠️ Please note: The TV menu interface may be updated by the manufacturer. If you can't find the option you need, check the official documentation for your model, as item names may change.
Once standby mode is activated, the TV will begin broadcasting its name to the network, making itself visible for searches. Some models require connection confirmation via the remote control when a connection request is received from the computer. Don't ignore any pop-up messages on the TV screen.
What should I do if my TV is not visible in the list?
Make sure AP Isolation isn't enabled on your router. This prevents devices on the network from seeing each other, making wireless projection impossible. You can also try rebooting your router.
Instructions: Connecting via the "Projection" function
The fastest way to display an image is to use Windows 10's built-in feature. This method uses the Miracast protocol and doesn't require any additional software. Make sure Wi-Fi is enabled on your laptop, even if you're using a cable connection.
To start the process, press the key combination Win + K on the keyboard. The "Connection" panel will open on the right. The system will automatically search for available wireless displays within range.

Stream media via DLNA
If your goal is not to duplicate your desktop, but to watch movies or photo galleries, it is more convenient to use technology DLNAIt allows you to stream media files directly, without burdening the processor with encoding the screen's video stream.
In Windows 10, this feature is available through "Media Streaming Options." You can select specific files in File Explorer, right-click, and select "Cast to Device." Your TV must support DLNA (most Smart TVs do).
This method is ideal for viewing high-quality video files, as there is virtually no latency and the image quality is not compressed as aggressively as with Miracast. However, the control interface will be limited to the TV's default player.
⚠️ Note: When using DLNA, only the media file content is streamed. Your desktop, browser, and other programs will not be visible. This mode is purely for entertainment purposes.
How to add a folder with movies?
You can configure libraries in the Streaming Media Settings app. Make sure your video folders are added to the default Windows libraries (Videos), otherwise the TV won't see them.
Solving problems and delays
The most common issue with a wireless connection is audio and video desync or noticeable cursor lag. This is usually due to Wi-Fi congestion or a weak signal. Try moving your laptop closer to the router or TV.
