Modern smartphones have long since become powerful multimedia centers, but even the highest quality screen Honor 9X A large screen can't always convey the scale of what's happening. Users often wonder how to stream content from a mobile device to a TV without unnecessary wires, relying solely on wireless technology. This allows you to transform an ordinary evening into a movie theater or show off vacation photos to friends on the big screen.
The process of synchronizing devices is based on the use of a local network Wi-Fi, which unites gadgets into a single ecosystem. The Honor 9X runs on Android with the EMUI shell, where broadcasting functions are built deep into the system., eliminating the need to search for third-party apps for basic tasks. However, despite its apparent simplicity, there are many nuances that depend on the TV model and software version.
In this article, we'll cover all available connection methods in detail, from built-in system tools to specialized apps. You'll learn how to set up a stable connection, which network parameters are critical, and what to do if your TV doesn't detect your smartphone. Understanding these processes will allow you to enjoy content without lag or image artifacts.
Technical requirements and equipment preparation
Before you begin setup, you need to make sure your equipment meets the minimum technical requirements for stable wireless data transmission. The key requirement is the presence of a module. Wi-Fi in both devices, and it is desirable that they support standards no lower than 802.11n, and ideally 802.11ac for transmitting high-definition video.
Finding your smartphone is critical Honor 9X and the TV on the same subnet. This means both devices must be connected to the same router. If you have a dual-band router, make sure the devices are connected to the same frequency, although modern routers often combine 2.4 GHz and 5 GHz networks into a single logical structure.
- 📱 Honor 9X smartphone with an active Wi-Fi module and the latest firmware version.
- 📺 A TV with Smart TV support or a connected TV set-top box (Android Box, Apple TV).
- 📡 A stable internet connection or a functioning local router network.
- 🔋 Make sure your smartphone's battery is at least 20% charged to avoid power-off during setup.
⚠️ Note: If your router is configured with AP Isolation, devices will not be able to see each other on the network. To enable the broadcast feature, you must disable this option in your router settings.
It is also worth checking if the function is enabled DLNA or Miracast On the TV itself. On some older models, these services must be activated manually through the network menu. Without discovery enabled, the TV will be invisible to smartphone search engines, and all connection attempts will result in a timeout error.
Using the built-in Screen Projection feature
The fastest and most efficient way to display images from your smartphone Honor 9X to a large screen is the use of a standard system function, which in the EMUI shell is called "Screen projection." This method implements the technology Miracast, which allows you to broadcast images in real time without the delays typical for streaming video.
To activate the feature, pull down the notification shade and locate the "Screen Projection" icon. If the icon is hidden, tap the panel editing icon (usually a pencil or three dots) and drag the desired element to the active area. Once tapped, the system will begin searching for available devices within range.
☑️ Check before connection
Once your TV appears in the list, simply tap its name. A connection confirmation prompt may appear on the TV screen, which you'll need to accept with your remote control. After this, the image from your phone will be fully copied to the TV, and you'll be able to control the content using your smartphone as a remote.
⚠️ Please note: When using screen projection, your smartphone may become hotter than usual due to the processor and Wi-Fi module operating under high load. It is recommended to remove the protective case for better heat dissipation.
The quality of the transmitted image directly depends on the signal strength. Wi-FiIf you notice image tearing or choppiness, try moving closer to the router or TV. The feature automatically adjusts the bitrate, but with a weak signal, it prioritizes smoothness over resolution.
Broadcast via YouTube app and streaming services
If your goal is to watch videos from online cinemas or video hosting sites, using system screen projection is not always optimal. Services like YouTube, Netflix or IVI have a built-in function Cast, which allows you to start playback directly on the TV, using your phone only as a remote control.
This method saves battery power significantly. Honor 9X and reduces processor load, as the video stream is sent directly from the internet to the TV, bypassing the smartphone. To use, the app on your phone must be logged in to the same account as the TV app, although simply being on the same network is often sufficient.
- 🎬 Open the video in the YouTube app on your smartphone.
- 📺 Click the broadcast icon (rectangle with Wi-Fi waves) in the corner of the player.
- 📲 Select your TV from the list of devices that appears.
- ▶️ The video will start playing on the big screen, and you can use your phone for other tasks.
The advantage of this method is support for higher quality standards, including 4K and HDR, if your TV and subscription plan allow it. System projection often limits FullHD resolution due to wireless bandwidth.
Why does the video lag when streaming on YouTube?
Delays may be caused by Wi-Fi congestion from other devices, slow internet speeds, or an outdated YouTube app on your TV. Try restarting your router.
It's worth noting that not all apps support this feature. Some video services block the ability to display protected content on external displays due to licensing restrictions. HDCPIn such cases, the system can only offer system screen projection, which is less effective.
Setting up DLNA to view photos and videos from your gallery
To view your personal media library stored in memory Honor 9X, the technology is ideal DLNAIt allows you to stream files directly from your gallery or video player to your TV, which acts as a renderer. This is convenient for showing off photos from a family celebration or watching downloaded movies.
On Honor smartphones, this feature is often integrated into the default video player or gallery. When opening a video, tap the "Cast" button or the screen icon. The phone will prompt you to select a device. If the built-in player doesn't detect the TV, you can use third-party solutions such as BubbleUPnP or VLC.
| Parameter | Screen projection (Miracast) | DLNA / Streaming | Google Chromecast |
|---|---|---|---|
| Transmission type | Mirroring the entire screen | Transfer a specific file | Streaming from the network |
| Impact on battery | High | Average | Low |
| Phone addiction | Full (screen active) | Partial (you can turn off the screen) | Minimum |
| Quality | Up to 1080p (signal dependent) | Original file quality | Up to 4K (depending on TV) |
Using DLNA eliminates the need for internet connection speed, as data transfer occurs within the local network. This is especially useful for viewing large files (several gigabytes in size) that are difficult or time-consuming to download directly to the TV.
Troubleshooting connection and device visibility issues
Despite the standardization of technologies, users often face a situation where Honor 9X If your TV isn't showing up in the list of available devices, the first step is to reboot both devices and the router. This simple step resolves up to 80% of network service caching and IP address conflicts.
If rebooting doesn't help, check your router's firewall or antivirus settings, if applicable. Sometimes, security mechanisms block ports used for device discovery. SSDPAlso, make sure your TV's software is up to date, as older firmware versions may not work correctly with new Wi-Fi Direct standards.
- 🔄 Check if the "Data Saver" mode is enabled on your phone, which may block background network services.
- 📶 Make sure that your phone and TV are connected to the same network (for example, not to the router's guest network).
- 🛡️ Temporarily disable the VPN on your smartphone, as it changes the network route and hides the device from local searches.
- 🔌 Try forgetting the Wi-Fi network on both devices and reconnecting using the password.
⚠️ Note: TV interfaces and Android versions are constantly being updated. The layout of menu items may differ from what's described. If you can't find the option you need, please refer to the official documentation for your TV model or go to the "Help" section in Settings.
In rare cases, the problem stems from frequency incompatibility. If the router broadcasts a 5 GHz network, but the TV only supports 2.4 GHz (or vice versa), some Miracast implementations may not be able to see each other, even though they have internet access. In such cases, creating a guest network with the required parameters or adjusting the router settings can help.
Alternative methods and use of adapters
If you connect using built-in methods Honor 9X If you can't connect to your TV, or your TV isn't a Smart TV, external adapters can help. Devices like Google Chromecast, Microsoft Wireless Display Adapter or similar dongles from Xiaomi and Realme turn any TV with HDMI into a wireless signal receiver.
The adapter plugs into the HDMI port and is powered by USB. To the phone, it appears as a standard output device, often requiring a companion app to guide you through the setup process. It's a versatile solution that performs more reliably than the built-in smart systems found on budget TVs.
Another option is to use a USB cable if the TV supports the format. MHL or Slimport, although in modern models Honor 9X The USB Type-C connector may not support direct video output without an active adapter (USB-C to HDMI). In this case, a special adapter with a signal conversion chip is required.
The method you choose depends on your goals. DLNA is suitable for occasional photo viewing, Miracast with its minimal latency is suitable for gaming, and for regular use of the TV as a monitor, it's better to purchase a high-quality external adapter that will handle video decoding.
Why is there no sound on the TV when connected via Wi-Fi?
Most often, the problem lies in Android's audio output settings. When connecting to Miracast, the sound should switch automatically. If this doesn't happen, check whether your phone is connected to a Bluetooth headset, as it may be prioritizing the sound. Also, try changing the audio format in developer options or restarting the app you're casting from.
Is it possible to play games on Honor 9X through TV without lag?
You can play games, but input lag will always be present over a wireless connection. This isn't a problem for turn-based strategy games or card games. However, for fast-paced shooters or racing games, wireless projection via Wi-Fi may be too slow. In such cases, a wired connection or streaming from a PC via Steam Link, where latency is better optimized, is preferable.
Does streaming via Wi-Fi use a lot of mobile data?
When using Miracast and DLNA technologies, traffic flows within the local network and doesn't consume any internet data. However, if you stream online videos (YouTube, Netflix), traffic is consumed, but it's through the router's Wi-Fi, not the 4G/5G mobile network, so this won't affect your plan if you have unlimited home internet.
