Modern smartphones have long since become powerful multimedia centers, capable of storing terabytes of high-resolution video. However, the screen of a mobile device, even one as high-quality as the Honor 9X, doesn't always allow you to appreciate the full beauty of the picture or share the experience with your family. That's why the question of how to connect a phone to a TV to watch movies via Wi-Fi on the Honor 9 X remains a pressing one for many users looking to transform their living room into a home theater.
The main advantage of a wireless connection is the absence of unnecessary wires that can get tangled underfoot and spoil the aesthetics of the interior. To achieve this, your smartphone And TV must be on the same local network to ensure stable video streaming without lag. It's important to understand that streaming quality directly depends on the router speed and modern TVs' support for the relevant data transfer protocols.
Owners of brand devices Huawei And Honor have access to proprietary technologies that simplify this process with just a few taps. In this article, we'll take a detailed look at all available connection methods, from built-in system functions to third-party apps. You'll learn how to avoid common mistakes and enjoy content on the big screen in maximum quality.
Checking compatibility and preparing equipment
Before setting up the broadcast, you need to make sure your equipment is technically ready. A key requirement for a wireless connection is that your TV supports the technology. Miracast (In some models, it may be called Wi-Fi Direct or Screen Mirroring.) If your Smart TV is several years old, it may not have a built-in Wi-Fi module, and external adapters will be required.
Both devices are - and Honor 9XThe phone and TV must be connected to the same Wi-Fi network. This is critical, as connecting the phone to mobile data (4G/5G) or the router's guest network will prevent devices from being discovered. Ensure that AP Isolation is not enabled on the router, which prevents devices within the network from communicating with each other.
⚠️ Important: If your router operates in dual bands (2.4 GHz and 5 GHz), try to connect both devices to the same frequency. Some older TV models may not detect devices on the 5 GHz network, and modern routers sometimes separate these networks into different SSIDs.
It is also worth checking the operating system version on your smartphone. Honor 9X EMUI or Magic UI, both based on Android, are currently the most popular skins. Make sure your system is updated to the latest available version, as security patches and wireless protocol improvements often come with software updates.
Using the built-in Huawei Share and Projection feature
The fastest and most native way to cast your screen Honor 9X To project to a TV, use the built-in "Project" feature. This technology is based on the Miracast standard and doesn't require any additional software. To get started, pull down the notification shade and look for the "Projection" or "Wireless Projection" icon.
Once the feature is activated, your phone will begin searching for available devices within range. A connection permission prompt may appear on your TV screen, which you'll need to confirm with the remote control. If your TV supports the technology, DLNA or proprietary protocols from the manufacturer (for example, Samsung Smart View), it may also appear in the list.
- 📱 Step 1: Open the control panel on Honor 9X by swiping down from the top.
- 📡 Step 2: Click on the "Projection" icon and wait for the name of your TV to appear.
- 📺 Step 3: Select your TV from the list and confirm the connection on both devices.
If the automatic search does not yield any results, you can use the settings menu. Go to Settings → More connections → ProjectionThe interface may differ depending on the firmware version, but the logic remains the same: turn on the switch and select the target device. After a successful connection, the smartphone's screen will be fully mirrored on the TV.
☑️ Check before connection
Broadcast via YouTube app and online services
Often, users don't need a full copy of their smartphone's screen, but simply want to play a specific video from the internet. In this case, the most effective method is to use the built-in "Cast" feature in video service apps such as YouTube, Netflix, or online movie theaters. This method is preferable because the video is transmitted directly from the server to the TV, reducing the load on the phone's processor.
To start broadcasting, open an app, such as YouTube, on your Honor 9XMake sure the app on your phone and the app on your Smart TV are signed in to the same Google account. This isn't always required, but it's recommended for stability. In the upper right corner of the app interface, look for the distinctive rectangle icon with Wi-Fi waves.
Clicking the icon will open a list of available devices. Select your TV, and the video will begin playing on the big screen. The advantage of this method is that you can control playback (pause, rewind, and adjust volume) from your phone, and use your smartphone for other tasks without interrupting the movie.
| Parameter | Full screen projection | Broadcast from the app (Cast) |
|---|---|---|
| Loading the phone | High (encodes video) | Low (remote control only) |
| Picture quality | Depends on Wi-Fi signal | Maximum (depending on TV) |
| Possibility of other tasks | No (screen is busy) | Yes (you can switch) |
| Battery consumption | Fast | Minimum |
Why might the video slow down when fully projected?
When projecting the entire screen, the phone encodes the video stream in real time and sends it to the TV. This creates a double load: on the smartphone's processor and on the Wi-Fi channel. If the router is old or the signal is weak, you will experience lag and image artifacts.
Setting up DLNA to view your media library
Protocol DLNA (Digital Living Network Alliance) is a standard that allows devices to share multimedia content within a home network. Unlike Miracast, which broadcasts a screen image, DLNA allows for the transfer of specific files: photos, music, and videos stored in the device's memory. Honor 9X.
To use this method, you need to install a media server app on your smartphone. Popular options include BubbleUPnP, LocalCast, or the built-in gallery functions. After installation, the app will scan your device and prompt you to select files to play. Then, select your TV from the list of playback devices.
This method is ideal for viewing family video archives or photos on a large screen. It doesn't require the smartphone screen to be constantly on and consumes less power than full projection. However, it's worth keeping in mind that DLNA doesn't support streaming protected content from some streaming apps due to DRM restrictions.
⚠️ Important: Video file formats must be supported by your TV. If your TV doesn't have a built-in codec for a certain format (for example, MKV with a specific audio codec), the file may not play, even if your phone can play it.
Solving common connection problems
Despite the simplicity of the technology, users often encounter situations where the phone can't see the TV or the connection constantly drops. One of the most common causes is the use of different router frequency bands. As mentioned earlier, if the phone is on 5 GHz and the TV is on 2.4 GHz, they may not "see" each other in some network configurations.
Another common issue is firewall or antivirus settings on the router that block local data exchange. Try temporarily disabling these protections to test. It's also worth rebooting the router, as an overflowing ARP address table can prevent new connections.
- 🔄 Reboot: Turn off and on your router, TV and phone.
- 🔒 Safety: Check if P2P connections are blocked in your router settings.
- 📶 Signal: Move closer to the router to avoid packet loss due to a weak signal.
If the problem is related to the TV's software, a firmware update may be required. Access the TV settings via the menu. Support → Software Update (the path may vary depending on the brand) and check for new versions. Outdated software often contains bugs that prevent Miracast protocols from working correctly.
Alternative methods and third-party applications
In cases where standard tools don't work or their functionality isn't sufficient, third-party solutions come to the rescue. Applications like TV Cast, AllCast or Web Video Caster Allow you to stream content to virtually any TV, even if it doesn't support standard protocols out of the box. These apps often have their own receivers or use emulation.
For advanced users with Android TVs, installing apps directly from the Google Play Store to your TV is a great solution. For example, by installing AirScreen or Receiver for AirPlay on the TV itself, you will be able to receive a signal from Honor 9X even more stable than through system means.
Also, don't forget about a wired connection via a USB-C to HDMI adapter. Although the request is for Wi-Fi, this method provides the best image quality without compression or lag. Honor 9X It's important to check for USB video output support, as not all models from this brand support video output via the charging port without the use of dedicated docking stations with DisplayLink technology.
Why doesn't my Honor 9X phone detect my Smart TV?
Most often, the problem is that the devices are connected to different networks (for example, one is a guest network, the other is the main network) or access point isolation is enabled on the router. Also, check if the TV firmware requires a firmware update.
Is it possible to stream a screen if there is no router?
Yes, if your TV supports Wi-Fi Direct or Miracast without an access point. In this case, your phone will create a direct connection to the TV, bypassing the router. However, your phone's internet connection will not work at this time.
Does connecting to a TV affect internet speed?
When using the Cast method (via YouTube, etc.), no, as the TV downloads the video itself. With full-screen projection (Miracast), the traffic goes through the phone, which can reduce the speed for other devices on the network if the bandwidth is limited.
How to improve picture quality over a wireless connection?
Use the 5GHz band for lower latency, ensure there are no thick walls between the router and your devices, and close background apps on your phone that consume data.
