Apple We've provided a variety of tools for comfortable work in conjunction with external displays, and their proper use will ensure you have uninterrupted access to your favorite movies.
Checking compatibility and preparing equipment
Before you begin the active setup phase, you need to make sure your equipment is technically ready for operation. Not all TV models support modern encryption standards, which are used by default. iPhoneFor example, older devices may not see a network if it operates in the 5 GHz band, while newer models, on the contrary, may ignore outdated security protocols. WPA.
Make sure your mobile phone plan has tethering enabled. Some providers automatically block it. TTL or require additional options to use the smartphone as a modem. Also, check your balance and remaining data plan, as streaming video consumes a significant amount of data.
⚠️ Important: If you have an unlimited data plan, carefully review your carrier's terms and conditions. Often, unlimited data is only available within apps on the phone itself, while data sharing with other devices may be charged separately or have speed restrictions.
To ensure a successful connection, please ensure the following conditions are met:
- 📱 On iPhone The latest version of iOS is installed to support the latest security protocols.
- 📺 The TV is equipped with a Wi-Fi module and supports 802.11 n/ac standards.
- 📡 There is a strong 4G or 5G signal from the operator's network in the coverage area.
- 🔋 The phone's battery charge is at least 30% or the device is connected to a charger.
Ignoring these basic requirements may result in the TV simply not seeing the network or constantly losing connection. Drivers Network modules in TVs are updated less frequently than in smartphones, so compatibility should be checked in advance.
Setting up modem mode on iPhone
The central element of our configuration is the correct launch of modem mode. In the operating system iOS This process is hidden deep in the settings, but it is critical for stable operation. Go to the menu Settings → Cellular → Personal Hotspot (or simply Settings → Tethering (in new versions). Here you need to activate the "Allow others" switch.
Pay special attention to the "Wi-Fi Password" field. By default, the system generates a complex character combination. For TVs where entering text using the remote control can be difficult, it's better to set a simpler but more secure password. Use a combination of 8-12 characters, including letters and numbers, but avoid special characters that the TV might interpret incorrectly.
An important point is the selection of the frequency range. In the modem mode menu (often hidden in the "Wi-Fi Settings" section within the modem menu or accessible via a code) 3001#12345#) you can switch the operating mode. If your TV is older, it may require a 2.4 GHz network. New models Smart TV They work better in the 5 GHz range, where there is less interference and higher speed.
Once the mode is activated, the phone screen will light up green or blue (depending on the model), and the word "Modem Mode" will appear in the upper left corner. This indicates that iPhone The network has started broadcasting and is ready to connect external devices. Now you can move on to setting up the TV itself.
Finding and connecting your TV to the network
The process of connecting a TV to the created network is not much different from the standard procedure, but has its own interface features. Take the remote control and go to the main menu.

Tap the "Screen Mirroring" icon (two rectangles) in Control Center or select the AirPlay icon in the video player.
| Parameter | AirPlay 2 | Standard DLNA | Lightning to HDMI cable |
|---|---|---|---|
| Quality | High (up to 4K) | Depends on the codec | Maximum |
| Delay | Minimum | Average | Absent |
| Convenience | High | Average | Low (wire needed) |
| Battery consumption | Average | Short | Charging is in progress |
A list of available devices will appear on your TV. Once selected, streaming will begin. The advantage of AirPlay is that it optimizes the data stream, often providing a better picture than built-in apps on the TV itself. Plus, you can control playback from your phone without leaving the couch.
It's worth noting that for AirPlay 2 to work, your TV must support this standard. Most modern models from Samsung, LG, Sony, and Vizio released after 2018 have built-in support. Older models may require a set-top box. Apple TV.
Speed optimization and troubleshooting
Even with ideal settings, you may experience slow speeds or video buffering. This is due to the specifics of your mobile network. 4G/LTE The connection is unstable and affected by many factors. To improve the situation, try moving your phone with the modem mode enabled closer to a window or to a location with the best reception.
Close all background apps on your iPhone that may be consuming bandwidth. App updates, iCloud photo syncing, and backups can all eat up your bandwidth, leaving your TV with minimal resources. Go to Settings → General → Content Update and temporarily disable background activity.
Why does the speed drop when connecting to a TV?
Speed may drop due to overheating of the smartphone's Wi-Fi module during prolonged use. Also, carriers may artificially limit speed (throttle) after a certain high-speed data allowance within the plan has been reached.
If your TV is losing network connection, try changing the network name on your phone. Sometimes devices remember old settings and conflict with new ones. By renaming your iPhone Settings → General → About → Name, you will force the TV to create a new connection with clean settings.
