Modern multimedia capabilities make it easy to display content from your PC monitor on a large TV screen without the hassle of cables. If you're wondering how to mirror your computer to a TV via WiFi in Windows 10, you're in luck: the operating system already includes all the necessary tools. This process, often referred to as "projection" or "screen mirroring," allows you to access photo galleries, movies, and games on screens of 50 inches or more.
The main advantage of a wireless connection is that there's no need to run HDMI cables across the room, which is especially important if the equipment is located in different corners of the room. However, for stable operation Miracast For Wi-Fi or DLNA, it's crucial that both devices are on the same local network. In some cases, a router isn't even necessary, as Wi-Fi Direct technology allows for a direct connection between the laptop and Smart TV.
Before setting up, make sure your TV supports Smart TV and has a built-in wireless module. Older models without smart features may require an additional adapter, such as a Chromecast or Miracast dongle, which plugs into the HDMI port. Let's explore all the available connection methods, starting with the operating system's built-in tools.
Using the built-in Connect feature in Windows 10
The fastest way to start streaming is to use a system utility that doesn't require installing any third-party software. In Windows 10, this feature is deeply integrated into the interface and can be accessed with a hotkey. You don't need to search through complicated settings in the Control Panel; just press Win + K on your keyboard to open the Connection sidebar.
Once the utility is launched, the system will automatically begin searching for available wireless displays within range. If your TV is turned on and in connection standby mode (often this mode) Screen Share or Miracast (On the remote), it will appear in the list. Click the device's name, and after a few seconds, the Windows desktop image will appear on the TV.
It's worth keeping in mind that image quality and lag directly depend on the power of your Wi-Fi router and interference in the air. This isn't a big deal for viewing photos or presentations, but in fast-paced games, lag can range from 0.5 to 2 seconds. If you plan to play games, it's best to use a wired connection or lower the streaming resolution.
⚠️ Important: If the "Connect" button is grayed out or the system displays "No displays found," your computer's Wi-Fi module may be disabled or the wireless adapter drivers may be malfunctioning. Check Device Manager.
In such cases, you need to manually change the display settings via the desktop context menu.
Setting up your TV to receive a signal
Before your computer can "see" your TV, it must be configured correctly. Smart TV interfaces vary across manufacturers (Samsung, LG, Sony, Philips), but the logic is similar. You'll need a remote control to access the signal source or app menu.
On Samsung TVs this feature is often called Screen Mirroring or is located in the Source menu. For LG, you need to launch the app Screen ShareOn Android TV (Sony, Philips, Xiaomi), simply turn on the TV and make sure it's connected to the same Wi-Fi network as your PC, as the Chromecast built-in protocol runs in the background.
- 📺 Press the "Input" or "Source" button on the remote control and select wireless connection.
- 📶 Make sure your TV is connected to a 5GHz Wi-Fi network for best speed.
- 🔒 Check if your router is set to AP Isolation, which prevents devices from seeing each other.
Some TV models require connection confirmation on the screen each time you try to connect. This is a security measure to prevent neighbors from accidentally or intentionally mirroring your TV. Be ready to press "Allow" on your remote when the appropriate notification appears.
☑️ Check TV readiness
Using apps from your TV manufacturer
If the standard Miracast protocol is unstable or not supported by your TV model, manufacturers offer their own solutions. These programs often offer advanced functionality, such as media management or screen cloning with reduced latency.
For owners of Samsung equipment, the application is relevant Samsung Smart View (Although support for the PC version is gradually being phased out in favor of mobile solutions, older versions still work). LG offers a program LG TV Plus, which allows you to not only broadcast your screen but also use your smartphone or PC as a remote control. Sony users can use the utility Video & TV SideView.
| Brand TV | Application/Function | Connection type | Peculiarities |
|---|---|---|---|
| Samsung | Smart View / AirPlay 2 | Wi-Fi Direct | 4K support, media library support |
| LG | LG TV Plus | Local area network | Mouse control, screen cloning |
| Sony | SideView / Chromecast | Wi-Fi | Integration with Google services |
| Philips | MyRemote / AirPlay | Local area network | Support for Ambilight sync |
Installing proprietary software may require registering a manufacturer account, which is worth considering if you value anonymity. Furthermore, such applications sometimes only work within a single subnet, so complex corporate networks with VLAN segmentation can be a barrier.
What should I do if the app doesn't detect the TV?
Make sure your antivirus or Windows Firewall isn't blocking incoming connections for this app. Try temporarily disabling the firewall and testing the connection. Restarting the Media Manager service in Windows also helps.
Broadcast via Google Chrome browser and Chromecast
One of the most universal methods, which works on virtually any Chromecast-enabled TV (either built-in or via a set-top box), is using the Google Chrome browser. This method is convenient because it doesn't require complex network settings and is cross-platform.
Open the Chrome browser on your computer, click the three dots in the upper-right corner, and select "Cast." From the menu that appears, you can choose to cast a specific tab, your entire desktop, or a single file. This is ideal if you want to show the contents of a webpage or a video from a website.
When you select the "Cast Desktop" option, the system will ask for permission to capture the image. Once confirmed, your PC screen will appear on the TV. It's important to note that in this mode, the computer's audio is also transmitted to the TV, making it convenient for watching movies from online cinemas.
⚠️ Please note: When streaming through a browser, the load on your computer's processor increases due to real-time video encoding. On low-end laptops, this may cause system lag.
If you don't have a Smart TV but have an HDMI port, you can purchase an inexpensive Google Chromecast adapter. It will turn any monitor into a smart screen capable of receiving a Wi-Fi signal. This is often a cheaper and faster solution than buying a new TV.
Connection problems and their solutions
Despite its apparent simplicity, wireless data transfer often faces technical obstacles. The most common issue is devices not seeing each other. This can be caused by Windows network profile settings. If your network is marked as "Public," the system blocks detection of other devices for security reasons.
To fix this, go to Settings → Network & Internet → Status and change the connection properties to "Private." It's also worth checking the service SSDP Discovery: click Win + R, enter services.msc, find the service and make sure it is running.
- 🔄 Restart your router, computer, and TV—this solves 80% of DNS cache and IP address issues.
- 📡 Make sure both devices are connected to the same frequency (2.4 GHz or 5 GHz), although modern routers often combine them into one network.
- 🛡️ Disable VPN connections on your computer, as they can change your virtual location and hide your PC from your local network.
Another common cause of problems is outdated Wi-Fi adapter drivers. Visit your laptop or motherboard manufacturer's website and download the latest driver for your wireless module model. Older versions may not support the standards. Wi-Fi Direct to the fullest extent.
Third-party programs for advanced features
