Modern smartphones such as HuaweiTVs have high-resolution screens, but viewing photos, videos, or presentations often requires a larger screen. Wirelessly connecting to a TV via Wi-Fi solves the problem of transmitting multimedia content without the hassle of cables. This is convenient when you need to show videos from your gallery or watch a movie on a large screen in high quality.
There are several proven methods for synchronizing devices that do not require HDMI cables. The main technologies are the standard Miracast (wireless display) and protocol DLNA for streaming files. The specific method you choose depends on the year of your TV and the operating system version. Android or shells EMUI/HarmonyOS.
Before starting setup, make sure both devices are on the same local network. A stable connection is critical for real-time, lag-free video transmission. If your router supports dual-band mode, it's best to use the 5 GHz frequency to reduce interference.
Technical requirements and equipment preparation
Successful synchronization of a smartphone and TV is only possible if basic network conditions are met. First and foremost, both devices must be connected to the same router. This is a fundamental requirement for local network protocols, as they only search for receivers within their subnet segment.
Please check your TV's software version. Older Smart TV models may not support modern codecs or security standards used by newer smartphones. HuaweiIn some cases, you may need to update your TV firmware via a USB drive.
⚠️ Note: Some providers use AP Isolation in their routers. If your phone can't see your TV, check your router settings—the "Client Isolation" box should be unchecked.
Check that Wi-Fi is enabled on both devices. For proper operation of the technology, Miracast Bluetooth may also be used for the initial handshake, so it's best not to disable it beforehand. Make sure your phone isn't in "Data Saver" mode, which can block background data transfers.
Using the built-in Wireless Projector feature
The fastest way to mirror your phone's screen to your TV is to use the system's native feature. On smartphones Huawei It is often called "Wireless Projection" or "Broadcasting". This technology is based on the standard Wi-Fi Direct, which allows you to transmit a video signal directly, bypassing the router, if the TV supports this option.
To activate this feature, pull down the notification shade and look for the "Wireless Projector" icon. If the icon isn't visible, click the edit button (usually a pencil or three dots) and drag it to the desktop. Once enabled, it will automatically search for available devices within range.
☑️ Connection algorithm
A connection permission prompt may appear on the TV screen. Use the remote control to confirm. After this, the image from your phone will be broadcast to the big screen in real time. Picture quality depends on the strength of the Wi-Fi signal and the airwaves.
It's worth noting that this method completely synchronizes your phone and TV screens. All notifications, incoming calls, and messages will be visible on the big screen, so it's best to enable "Do Not Disturb" mode before watching movies.
Setting up DLNA via the Huawei Video app
If you don't need to duplicate the entire screen, but only need to broadcast a specific video file, it is more convenient to use the protocol DLNAThis is a standard that allows media content to be transmitted between devices on the same network. In phones Huawei For this purpose, the standard "Video" or "Gallery" application is often used.
Open the desired video file or movie in the app. In the upper or lower right corner of the interface, find the "Cast" icon (looks like a rectangle with waves). Click it, and the system will offer a list of compatible devices. Select your TV from the list.
Unlike mirroring, the phone only acts as a remote control. The video is buffered and played back by the TV itself, saving battery life and allowing the phone to be used for other tasks while watching. However, rewinding may experience a slight delay.
What to do if there is sound but no picture?
In some cases, DLNA streaming may cause desynchronization or a missing video stream. Try changing the video file format or using a third-party player, such as VLC for Android, which has a built-in Cast function and supports more codecs.
Protocol DLNA It's perfect for viewing photos and slideshows. You can select an album from the gallery and launch it full-screen. This is the perfect solution for sharing family photos with guests without having to connect a laptop or flash drive to the TV.
Streaming via Google Home and Chromecast
Many modern TVs have built-in support for this technology. Chromecast built-inIf your TV belongs to the platform Android TV or has the corresponding logo, you can use the application Google Home to control the broadcast. This is the most stable way to stream content from the internet.
Install the application Google Home From the app store (if Google services are installed on your device). Open the app and find your TV in the list of devices. Tap the device name, then select the "Cast Screen" button.
This method is especially effective for broadcasting browser tabs. Chrome or apps that don't have their own "Cast" button. Streaming quality is usually high, but depends on your internet speed if the content is streamed from the network rather than played locally.
| Method | Transmission type | Router dependency | Best use |
|---|---|---|---|
| Miracast | Screen mirroring | Low (Wi-Fi Direct) | Presentations, photos, games |
| DLNA | Streaming video | High | Watching movies from memory |
| Chromecast | Content casting | High | YouTube, online cinemas |
| Third-party applications | Miscellaneous | Average | Old TVs without Smart |
Third-party applications for complex cases
In situations where built-in features don't work or the TV is an older model without Smart features, third-party apps can help. One of the most popular solutions is TV Cast or Web Video CasterThey allow you to stream video using a local IP address.
The principle of operation of such programs is simple: you install the application on your phone Huawei And, in some cases, a companion app for your TV (if it's an Android TV). The app scans the network, finds a receiver, and creates a channel for transmitting the video stream.
For TVs without an operating system, you can use special adapters (such as Miracast dongles) that plug into the HDMI port. The phone sees this adapter as a regular wireless device and connects to it in the standard way via the "Wireless Projector" menu.
Some apps allow you to control playback using voice commands or create playlists. This adds additional convenience to using the media center. However, free versions of these programs often contain ads that can interrupt your viewing experience.
Troubleshooting connection and latency issues
The most common problem with a wireless connection is audio and video desynchronization or intermittent image flickering. This indicates an unstable connection. Try moving closer to the router or TV to prevent signal attenuation.
If you're using the 2.4 GHz frequency, the channel may be heavily polluted by neighboring networks. Switching to 5 GHz significantly improves the bandwidth needed to stream high-resolution video. It's also worth checking that your phone isn't running any background downloads.
⚠️ Warning: Antivirus software or firewalls on your router may block ports used for DLNA and Miracast. Try temporarily disabling traffic filtering for diagnostic purposes.
In some cases, resetting the network settings on your phone can help. Go to Settings → System & updates → Reset → Reset network settingsThis won't delete your personal data, but it will reset your Wi-Fi and Bluetooth settings to factory defaults, which often resolves software conflicts.
Frequently Asked Questions (FAQ)
Is it possible to connect a Huawei phone to a regular TV without Smart TV?
Yes, this is possible. To do this, you'll need to purchase a special adapter (such as an AnyCast or Miracast receiver) that plugs into your TV's HDMI port. Your phone will see this adapter as a wireless display and stream the image to it.
Why does the quality of YouTube videos decrease when streaming?
Decreased video quality (artifacts, pixelation) is usually caused by slow internet speeds or a weak Wi-Fi signal. Try lowering the video quality in your player settings or restarting your router. Also, make sure your phone isn't too far from the access point.
Is the sound streamed via Wi-Fi or do I need separate speakers?
