Connecting Xiaomi Redmi Note 7 to TV via USB-cable: Full instructions

Modern smartphones like the Xiaomi Redmi Note 7 have powerful multimedia capabilities that are often wanted on the big screen. USB-But this is not always obvious, because the standard port is the same. USB The 2.0 Type-C has its own technical limitations.

Unlike flagship devices that support DisplayPort Alt Mode, budget and mid-budget models require a special approach to connecting. In this article, we will discuss in detail all possible connection scenarios, from simple data transfer to complex methods of mirroring the screen through software interfaces.

It is important to note that directly connecting a USB-to-HDMI cable without additional adapters or software crutches in this case will not work for video output, but there are proven methods of using the USB interface to achieve the desired result, which we will talk about in a moment.

Technical limitations of the USB interface in Redmi Note 7

To understand the processes that take place when connecting a smartphone and a TV, you need to consider the architecture of ports. Redmi Note 7 has a USB Type-C connector that supports the USB 2.0 standard. This means that data transfer speed is limited, and most importantly, there is no native support for video transmission via cable.

Many users mistakenly believe that any Type-C cable is capable of transmitting images, as some models from Samsung or Huawei do. In the case of Xiaomi in this series, the port is used mainly for charging, transferring files and debugging. Video output via USB-C in Redmi Note 7 is not hardware implemented at the level of the screen controller.

However, physical connectivity is possible and even necessary for certain use cases, such as sending heavy video files to a TV via a file system or establishing a stable communication channel when using third-party translation applications, and understanding these limitations will help avoid buying unnecessary adapters.

• 📱 Port port USB Type-C only supports data transfer protocol USB 2.0.
• 🚫 There is no support for technology MHL or Slimport for direct video output.
• 🔋 Charging of the device is possible simultaneously with the transfer of data, but the current may be limited.
• 💾 The maximum file transfer speed is about 480 Mbps.

⚠️ Note: Buying cheap adapters "USB-C on HDMI" The Redmi Note 7 is 99% useless from Chinese marketplaces, and the device simply won’t be able to recognize them as video output, and the screen will remain black.

Regime. USB-debugging and system preparation

If your goal is not just to flip a photo, but to use the phone as a remote or signal source for complex applications, you'll need to activate hidden settings. The first step is to turn on developer mode, which allows the Android system to receive commands from external devices or software controls.

To activate, you need to go to the Settings menu → About the phone and seven times quickly press the item Version MIUI. Once you've become a developer, a new section will appear in the settings menu, and that's where the keys to advanced interface management are hidden.

Inside the For Developers menu, we are interested in USB Debugging, which allows a computer or other device to interact with the phone at a deep level, and we also want to look at the default USB configuration setting, where you can choose file transfer mode (MTP) instead of just charging.

Security needs should not be ignored. When you first connect to a new device (television or set-top box), a trust dialog will appear on your smartphone screen. Debugging permission is critical to many translation applications that use the same technology. USB-protocol.

Use of the USB-content-access modem

One of the most stable but rarely used ways to interact with your TV and smartphone is to organize a local network via USB. If your Smart TV supports external devices via USB and has a networking feature, you can use your phone as a network card.

In the phone settings, in the section "Connection and Sharing", activate the function USB-modem: When connecting the cable to the TV (if it supports the host reum or via the USB-Hub, the phone will create a network connection, which allows you to stream media content over protocols. DLNA or through embedded media players.

This is especially useful when the Wi-Fi network is overloaded or unstable. The cable connection provides constant speed and no buffering delays. However, to play video directly from the phone's memory, the TV must be able to work with network folders.

• 🌐 Activate. USB-modem in the settings of the access point.
• 🔌 Connect the cable to USB-TV port (host support required).
• 📂 Use the TV file manager to access your phone’s network resources.
• ⚡ Connection speed is more stable than over a wireless channel.

If the TV doesn’t see the phone USB-modem, try installing a media player app on TV that supports network protocols, for example, VLC or MX Player.

Applications for broadcasting the screen via USB

Because there's no hardware video output, software solutions come to the rescue, and there are applications that compress the video stream of the screen and transmit it through the screen. USB-This often requires the installation of a server part on a PC or the use of special receivers, but there are also options for working directly.

One popular method is to use technologies like Scrcpy (albeit more commonly for PCs) or their mobile counterparts, which is to capture an image from the screen and transfer it over the ADB (Android Debug Bridge) protocol via USB, which requires installing the appropriate receiver app on the Smart TV if its OS allows.

A more affordable option is to use remote applications that USB-connection (if available) OTG The adapter and the Ethernet adapter for TV are controlling the content, but it's Mirroring that's where the most common bundle is: the app on the phone. + A TV application that operates on a single network, where USB Used only for power or initial synchronization.

When using applications like ApowerMirror via USB, it is important to remember the load on the processor. Decoding the video stream in real time can cause heating of the Redmi Note 7.

Transfer of Multimedia Files Directly

The easiest and most reliable way to use USB-The cable is the drive mode, and by connecting the phone to the TV, you can access the gallery and the video, and the TV sees the smartphone as a simple flash drive or an external hard drive.

⚠️ Attention: When connected in mode MTP TV may not see files if they're in Android system folders.Look for media in folders DCIM, Download or Movies.

Alternatives: Cast and wireless technologies

Speaking of connecting the Redmi Note 7 to the TV, it is impossible not to mention that the cable is not a good idea. USB — It's not the only way, and it's often not the most convenient way. MIUI) Allows you to broadcast a screen or individual applications without wires.

Cast requires both the phone and the TV to be on the same Wi-Fi network, and the Translation feature in the notification curtain or in the YouTube app will automatically find the compatible TV. USB-Port for charging, which is important for long viewing.

If the quality of wireless connection leaves much to be desired, and the USB cable for video signal is not suitable, the only high-quality wired solution is the use of USB-C to HDMI adapters with an active chip (DisplayLink), but their compatibility with MIUI and Redmi Note 7 is not guaranteed and requires experimentation.
