A modern smartphone, such as Honor 9has powerful multimedia potential, which is often not fully realized due to the small screen. You're watching an exciting TV series or have downloaded a new movie, but the display diagonal is simply not enough to create the effect of complete immersion. Connecting to a large TV screen solves this problem, turning the living room into a home theater in just a couple of clicks.
Fortunately, the era of tangled balls of wires and adapters is gradually becoming a thing of the past. Wireless communication technology allows you to broadcast content directly via the network Wi-Fiusing built-in protocols Android. Owners of Huawei i Honor with the shell EMUI are especially lucky: the system already contains all the necessary tools for screen duplication or video streaming.
In this article we will look in detail at how to set up a connection between your smartphone and TV without using physical cables. We'll look at both standard system features and third-party solutions that may be needed if your TV doesn't support modern standards. You will learn how to control playback, eliminate delays and enjoy a high-quality picture.
Preparing equipment and network for broadcast
Before you start setting up, you need to make sure that both devices are ready for interaction. The foundation of a wireless connection is a stable local network. Make sure that your Honor 9 and TV are connected to same Wi-Fi network. If your router supports dual bands, it is better to use the 5 GHz frequency to transmit high-definition video, as it provides greater bandwidth.
Check the software version on your smartphone. Go to Settings → System → Software update and make sure that you have the latest available version installed EMUI. Old firmware may contain errors in the operation of the module Miracast, which will lead to interruptions in the connection or lack of sound.
⚠️ Attention: Some older TV models may not support modern Wi-Fi encryption standards. If the devices do not see each other, try temporarily disabling password protection on the router's guest network to check
It also makes sense to reboot the router before the connection procedure. This will clear the network settings cache and issue fresh IP addresses to devices, which often solves visibility problems on the local network. After rebooting, wait until the TV is fully loaded and only then turn on the smartphone screen.
☑️ Check before connecting
Using the built-in “Wireless Screen” function
The easiest and most reliable way to duplicate an image is to use the native shell function EMUI, which is called “Wireless Screen”. This method implements technology Miracastthat allows you to transmit a video stream and audio directly to a compatible TV without the delays typical of some applications.
To activate the function, open the control panel by swiping down from the top of the screen Honor 9. Find the Wireless Screen icon (sometimes it's hidden behind the pencil-shaped panel edit button). After pressing, the smartphone will begin searching for available devices within the network range.
If your TV supports the technology Screen Mirroring or Wi-Fi Direct, it will appear in the list. Click on your TV's name and your phone's image will appear on the big screen. It is important to understand that in this mode everything that happens on the smartphone display is broadcast, including notifications and the desktop.
If the “Wireless Screen” icon is not in the curtain, go to Settings → Device connections → Wireless screen and turn on the switch there.
In some cases, you may need to confirm the connection on the TV screen using the remote control. Just select "Allow" or "Connect". Once the connection is established, you can expand any video player or browser to view the content in full screen mode.
The “Wireless Screen” function duplicates the entire smartphone interface, so incoming calls or messages will be visible on the TV to everyone present in the room.
Video broadcasting via the DLNA protocol and Chromecast
Unlike complete screen duplication, technologies DLNA and Google Cast allow you to transfer only the media file, freeing up the smartphone for other tasks. This means that you can start a movie on the TV, and then minimize the application or even turn off the phone screen - playback will continue.
To work with DLNA on Honor 9 the Gallery application or the built-in video player is often used. Open the desired video file, click on the “More” button or the broadcast icon (a rectangle with waves) and select your TV from the list of devices. The TV itself will download and play the file.
If you use streaming services, such as YouTube or Netflix, look for the Chromecast icon directly in the application interface. This is the highest quality way to watch, since the video is downloaded by the TV directly from the Internet, bypassing the phone, which saves battery power and guarantees high picture resolution.
| Connection method | Transmission type | Impact on the battery | Picture quality |
|---|---|---|---|
| Miracast (Wireless screen) | Full duplication | High | Depends on Wi-Fi signal |
| DLNA | Media file only | Low | Original file quality |
| Chromecast | Streaming video | Minimal | Up to 4K (depending on TV) |
Setting up third-party applications for broadcasting
If the built-in tools do not work or your TV belongs to the old generation of “non-Smart”, third-party applications from the store will come to the rescue Google Play. One of the most popular solutions is an application TV Cast or analogs like BubbleUPnP.
Install the selected application on Honor 9 and run it. The app will scan the network and find available receivers. Most of these utilities have a built-in browser: go to a website with an online cinema through this browser, and the broadcast button will become active.
Some applications allow you to broadcast files stored in the phone’s memory, even if the TV does not support the required codec. In this case, the application acts as an on-the-fly converter, sending an already prepared video stream to the TV. This requires a more powerful smartphone processor.
⚠️ Warning: Free versions of streaming applications often contain intrusive advertising that may block the interface while searching for devices. Be prepared to close the pop-up window to continue setting up.
For advanced users, it is possible to install the server part on the TV (if it is Android TV) and the client part on the phone. This gives you maximum control over your media library and allows you to create playlists that are accessible to all devices in the house.
What to do if the application does not see the TV?
Make sure that the “AP Isolation” function is disabled on the router. This setting prevents devices on the same Wi-Fi network from communicating with each other, which blocks the operation of broadcasting applications.
Solving common problems with connection and delays
Even with the correct setting, users may encounter image artifacts, desynchronization of audio and video, or frequent connection dropouts. Most often, the reason lies in an overloaded wireless channel or a weak signal at the location of the TV.
Try changing the output resolution settings. In the “Wireless Screen” menu on Honor 9 sometimes you can select compatibility mode or reduce the resolution to 720p. This will reduce the load on the communication channel and make the picture smoother, although less detailed.
If there is a delay in the sound (lipsync), check the settings of the TV itself. The sound menu often has an “Audio Sync” or “Audio Delay” option that can be adjusted manually. Also try turning off any sound effects like virtual surround sound on your TV.
When watching action scenes in games or action movies, use a wired connection or reduce the quality of the stream to 1080p to minimize input lag.
In case of constant interruptions, check whether other applications that actively use the network, for example, torrent clients or cloud synchronizers, are running in the background. Close them through the task manager before starting to watch the movie.
Features of working with different types of TVs
Different manufacturers implement support for wireless standards in their own way. TVs Samsung use technology AllShare Castthat is fully compatible with Miracast, but sometimes requires manual activation of the function in the “Network” menu. On remote controls LG there may be a separate button Input to select the “Screen Share” source.
Devices based on Android TV (for example, from Sony or Philips) have built-in support Chromecast, which makes them an ideal pair for smartphones with Google services. Owners of older models may need to purchase an external set-top box, such as Chromecast or Fire TV Stick.
If you have a TV with a proprietary operating system (for example, older models Sharp or Toshiba), the likelihood of native support may be low. In such cases, the only working option is to use external adapters or connect a smartphone via a USB cable in storage mode (although this is no longer a wireless method).
⚠️ Attention: TV menu interfaces are often updated by the manufacturer. If you do not find the described item in the settings, refer to the instructions for your specific model or check the “Help” section in the TV menu.
Do not forget that the quality of signal reception depends not only on the router, but also on the location of the TV antennas. If the TV is in a niche or behind metal furniture, the signal may be shielded, which will lead to a drop in picture quality.
Protocol compatibility is a key success factor. Make sure that your TV supports the Miracast standard or has a built-in Chromecast receiver for trouble-free operation with Honor 9.
Why is there no sound on the TV when connected?
Most often, the sound continues to come through the smartphone speaker because the receiver device is not selected in the Bluetooth or audio output settings. When using Miracast, the sound should switch automatically. Check if your phone is connected to a Bluetooth headset that can intercept the audio stream.
Is it possible to watch movies with the Honor 9 screen turned off?
Only when using DLNA or Chromecast technologies (cast button inside the application). If you use the “Wireless Screen” (duplicating) function, then the smartphone screen must be turned on, otherwise the broadcast will be interrupted or the phone will go into sleep mode.
Does the connection affect the Internet speed?
When using Miracast, the Internet is not used, the transmission occurs directly between devices. When using Chromecast or online cinemas, traffic goes through the router, which may slightly reduce the speed for other devices on the network, but this is usually not noticeable with a broadband connection.
Is it safe to stream personal photos to public Wi-Fi?
No, on public networks (cafes, hotels) other users can theoretically intercept the stream or see your device in the list of available ones. To broadcast personal content, use only a secure home network or mobile access point.
