Modern smartphones, including popular models HonorMobile devices have become powerful multimedia centers capable of playing high-definition content. However, the screen size of a mobile device is often insufficient for comfortable viewing of movies or family photos. Fortunately, wireless data transmission technologies make it easy to solve this problem by displaying images directly on a large TV screen.
Smartphone connection process Honor to the TV via Wi-Fi is based on the use of standard protocols such as Miracast or DLNAThese technologies are built into the Android operating system and are supported by most modern Smart TVs. You won't need additional cables or complex adapters if both devices are on the same local network.
The advantage of this method is the absence of physical limitations in cable length and the ability to control playback directly from your phone. In this article, we'll cover all available connection methods in detail, from built-in system features to third-party apps. We'll also cover common errors and troubleshooting steps.
Technical requirements and equipment preparation
Before you begin setup, you need to make sure your equipment meets the minimum requirements for stable video streaming. First and foremost, both devices—a smartphone Honor The device and TV must be connected to the same Wi-Fi network. This is critical, as using different networks (for example, a guest network and a primary network) will prevent the devices from being discovered.
The second requirement concerns the software version. On smartphones Honor, running under shell control Magic UI or EMUI, broadcast functions may have different names. Make sure the system is updated to the latest available version to eliminate software errors in communication protocols.
It's also worth paying attention to the Wi-Fi router's operating frequency. For high-definition video transmission (Full HD or 4K), it's preferable to use the band 5 GHzIt provides higher bandwidth, which reduces the risk of delays or desynchronization of sound and video.
⚠️ Attention: If your router supports the technology AP Isolation (Client Isolation), devices on the network will not see each other. This feature must be disabled in the router settings.
Finally, check your smartphone's battery. Wireless video streaming consumes significant power, so it's recommended to keep your device charged or connected to a power source during extended viewing.
Using the built-in "Screen Projection" feature
The easiest and fastest way to display an image from a smartphone Honor on the TV - use the standard system function. In the shells Honor It is most often called "Projection" or "Wireless Projection". This method is based on the technology Miracast, which allows you to broadcast images in real time with minimal delay.
To activate the feature, unlock your phone and pull down the notification shade. Find the "Projection" icon (sometimes it's hidden in an additional menu that can be accessed by swiping down or right). If the icon isn't in the quick access menu, go to Settings → More → Projection.
Once enabled, your phone will begin searching for available devices on your local network. A connection request may appear on the TV screen, which you must confirm with the remote control. Some TV models require manual activation of signal reception mode via the menu. Source or Input.
☑️ Check before launching the projection
It's important to note that when using Miracast, your phone's screen is completely mirrored on your TV. This means any notifications, incoming calls, or user actions will be visible on the big screen. For a more comfortable viewing experience, you can rotate your phone horizontally.
Broadcast via YouTube app and streaming services
If you're watching videos from platforms like YouTube, Netflix, or online movie theaters, using screen mirroring isn't always effective. It uses more power and can reduce image quality. There's a protocol for such cases. Google Cast (Chromecast built-in), which is built into many modern TVs.
The connection process is different in this case. You don't need to search for the TV in your phone's settings. Simply open an app (like YouTube) on your smartphone. Honor and find the broadcast icon. It's usually located in the upper-right corner of the interface and looks like a rectangle with Wi-Fi waves in the corner.
By clicking this icon, you'll see a list of available devices. Select your TV from the list. Once connected, playback controls (pause, rewind, and volume) will remain on your phone, and the video will play directly on your TV over the internet, without loading your smartphone's processor.
| Parameter | Screen projection (Miracast) | Broadcast (Cast/DLNA) |
|---|---|---|
| Operating principle | Full screen mirroring | Transferring a link to content |
| Battery consumption | High | Short |
| Using the phone | Limited (visible on TV) | Free (can be folded) |
| Video quality | Depends on the phone's power | Maximum (depending on TV) |
Please note that not all apps support the Cast function. If the cast icon is missing, it means the app developer hasn't implemented this feature or your TV doesn't support the required protocol.
Connecting to TVs of different brands
Although wireless transmission standards are uniform, TV manufacturers often use their own names for signal reception functions. For smartphone owners Honor It is useful to know what exactly the desired mode might be called on the TV screen, so as not to get confused in the menu.
On TVs Samsung the function is often called Smart View or simply "Screencasting". On /lg> devices it may be called Screen ShareOn TV Sony And PhilipsFor Android TV devices, the process is usually straightforward and doesn't require any additional modes; simply select the device from the list on your phone.
If you have an older generation TV without Smart TV, but connected to Wi-Fi via an external set-top box (for example, Android Box or Apple TV(Although the latter may have some compatibility issues with Android), the operating principle remains the same. The set-top box must be active and on the same network.
Problems with codecs
Sometimes a video may not play or have no sound due to audio codec incompatibility. In such cases, installing a third-party player on your TV set-top box that supports AC3 or DTS formats can help.
In some cases, you may be required to enter the PIN code displayed on your TV screen into the corresponding field on your smartphone. This is a security measure to prevent unauthorized access to your screen.
Third-party streaming apps
Built-in features don't always work perfectly, especially if your TV isn't smart or has outdated firmware. In these cases, third-party apps available in the store can help. AppGallery or Google Play.
One of the popular solutions is the application TV Cast or similar programs. These programs scan the network for DLNA devices and allow you to stream video files, photos, and even browser content. They often have more flexible quality and buffering settings.
Another option is to use emulator applications such as AirScreen (installed on the TV if it's an Android TV) or their phone equivalents. They create a virtual bridge between devices, improving protocol compatibility.
⚠️ Please note: Free versions of third-party apps often contain ads that may obscure the image or interrupt playback. A paid subscription may be required for a comfortable experience.
When choosing an app, pay attention to ratings and reviews. Some programs can overheat your device or be unstable with certain router models, causing network interference.
Solution and troubleshooting
Despite the simplicity of the technology, users often encounter connection issues. The most common one is that the phone doesn't detect the TV. In 90% of cases, this can be resolved by checking the network: make sure both devices are connected to the router's main SSID, not to the guest network or the 2.4 GHz band if the router splits them into different subnets.
The second common issue is low frame rate or constant buffering. This indicates a weak Wi-Fi signal. Try moving closer to the router or reducing the streaming video quality in the app settings. Also, closing background apps on your phone can free up CPU resources for encoding the video stream.
If there's sound but no picture (or vice versa), check the HDMI settings on your TV. Sometimes you need to switch the HDMI mode in your TV settings from "PC" to "AV" or vice versa to properly synchronize the signal format.
If wireless methods are completely inoperative, you can use a cable connection via a USB-C to HDMI adapter, if your model Honor Supports video signal output through the charging port.
Why is there only audio and the screen is black?
This often happens when trying to play protected content (DRM) via the Miracast protocol. Some services block screen mirroring to prevent piracy. In this case, the only solution is to use the built-in Cast function within the app or an HDMI cable.
Is it possible to play games on TV using your phone?
Yes, using screen projection mode. However, input lag can be noticeable, especially in fast-paced shooters. For gaming, it's best to use a wired connection or play games that don't require instant reaction time.
Does watching on a phone affect the picture quality on TV?
When using Cast mode (YouTube, etc.), no, the phone functions as a remote control. When using projection mode (Miracast), active actions on the phone (opening menus, notifications) will be displayed on the TV.
