Connecting Xiaomi Redmi Note 7 to TV via HDMI: Full Guide

Modern smartphones like the Xiaomi Redmi Note 7 have powerful processors and high-quality screens, but sometimes 6.3 inches diagonal is not enough to comfortably watch videos or show presentations. In such situations, the ability to display images on a large TV screen comes to the rescue. Users often look for a way to connect their gadget through an HDMI cable, believing that this is the most reliable and high-quality option for signal transmission.

However, before you run to the store for wires, you need to understand the technical features of your device. Redmi Note 7 is based on the Snapdragon 660 processor and is equipped with a USB Type-C port, but not all connectors of this type support direct output of video. Understanding the architecture of the ports will help to avoid unnecessary costs and frustrations associated with idle adapters.

In this article, we will take a closer look at whether you can connect the Xiaomi Redmi Note 7 to your TV directly via HDMI, what alternative broadcast methods are available, and how to set up a wireless connection if a wired version is not available. We will take a look at the nuances of data protocols and offer proven solutions for screen mirroring.

Technical limitations of the USB-C port in Redmi Note 7

A key feature in wired connectivity is the USB Type-C support for Alt Mode (Alternate Mode) technology, which allows video transmission directly from the processor to an external display via the charging connector. Unfortunately, in the low-end and mid-range smartphones, which include the Redmi Note 7, manufacturers often save on controllers, leaving the port functional only for charging and data transfer.

Xiaomi engineers have equipped this model with a version 2.0 port that does not support the DisplayPort Alt Mode or MHL (Mobile High-Definition Link) standard, which means that a simple USB-C HDMI adapter purchased from a nearby electronics store will likely fail to work with a 99% probability.

⚠️ Note: Buying cheap passive adapters USB-C to HDMI The Redmi Note 7 is a waste of money, and the device cannot physically send a video stream through that port without a dedicated encoder.

Are there exceptions? In theory, there are active adapters with a DisplayLink chip that encode the image into a data stream and transmit it over USB. However, these devices require special drivers that do not always work consistently on the MIUI shell, and the delay in the signal itself makes viewing dynamic content uncomfortable.

Alternative: Miracast and Chromecast wireless technology

Since direct wired method in Redmi Note 7 is almost impossible without complex and expensive crutches, the most rational solution is the use of wireless technology. the smartphone supports the Miracast standard (Wi-Fi Display), which allows you to broadcast the screen to any compatible TV or console without losing significant quality.

To activate this feature, the MIUI shell has a built-in utility. You don't have to download third-party apps, you just need to use system settings, and this method is ideal for viewing photos, video from a gallery or showing documents where split-second latency is not critical.

Also worth mentioning is support for Google Cast (Chromecast built-in) technology, if your TV is running Android TV or has Chromecast support built in, you can stream content from apps like YouTube or Netflix directly without loading your phone’s processor with full screen mirroring.

💡

To minimize wireless delays, make sure that both your smartphone and TV are connected to the same Wi-Fi network, preferably in the 5GHz band.

Step-by-step: setting up the screen broadcast

Connecting the Xiaomi Redmi Note 7 to your TV via a wireless interface is simple, but requires careful consideration when choosing a TV signal source. First, make sure your TV is on and switched to Wi-Fi reception mode (often called Screen Mirroring, Broadcast or Miracast).

Then pick up your smartphone and unlock it. You need to get into the Quick Settings menu or the system connectivity menu. MIUI may vary slightly between versions of the firmware, but the logic remains the same.

Once paired successfully, you’ll see your Redmi Note 7 screen on your TV. If the picture quality seems low, check the resolution settings in the projector menu (if this option is available in your version of the software) or simply run high-quality videos, as some apps will adapt the bitrate to the communication channel.

Use of Mi Remote and IR port

A unique feature of many Xiaomi smartphones, including the Redmi Note 7, is the presence of an integrated infractory port (IR Blaster).Although this does not allow for video transmission, it gives a huge advantage in controlling the TV.

This feature requires the Mi Remote app, which is pre-installed on the system, and allows you to control volume, switch channels, and log into the TV settings menu, which is especially useful if your native remote is lost or not working properly.

It's important to understand the difference: an infrared port doesn't broadcast a picture, it just sends commands to the TV. To display an image, you still need one of the technologies described above (Wi-Fi or Wi-Fi). HDMI-console), but you will manage the playback process through the smartphone screen.

⚠️ Attention: the IR port only works within line of sight, and if there is an obstacle between the phone and the TV receiver, the command will not be executed, unlike Wi-Fi, which passes through walls.

In the Mi Remote app settings, you can select a model of your TV from a huge database, and if your model is not listed, you can use the autocode selection feature, sequentially testing signals before the TV reacts.

Connection problems and how to solve them

Even with wireless methods, Redmi Note 7 users may face difficulties, and it often happens that the phone simply “does not see” the TV in the list of available devices, and the first thing to do is to make sure that both devices are on the same subnet.

Sometimes AP Isolation routers block device interactions within the network. If you use a guest Wi-Fi network, try switching to the main one. Also, problems can arise with dual-band routers if one device sits at 2.4 GHz and the other at 5 GHz, although modern routers usually know how to throw traffic between bands.

Another common problem is desynchronization of sound and video, which is often treated by restarting the Wi-Fi module on a smartphone or temporarily shutting down Bluetooth, which can cause interference in the 2.4 GHz frequency range.

💡

If your phone can’t see the TV, try restarting your router and temporarily shutting down your phone. VPN on a smartphone, as they often change the region or IP-address by hiding the device from the local network.

Comparison of Connection Methods for Different Tasks

The way you connect the Xiaomi Redmi Note 7 to the big screen depends on your ultimate goals. For games, a wired connection would be ideal, but because of its inaccessibility, you have to make trade-offs. For watching movies, wireless is great, and for presentations, you better use specialized applications.

If you need an HDMI (for example, to connect to an old projector without Wi-Fi), the only working option is to buy an Android set-top box (TV Box), which connects to the HDMI TV, and the phone will broadcast the image to it through the air, which makes any screen “smart”.

Consider the main use cases:

• 🎮 Games: Only wired connection via the console or low latency over 5GHz Wi-Fi.
• 🎬 Movies: Wireless streaming via Chromecast or built-in player.
• 📊 Presentations: Using applications like Office with slide output.
• 📸 Photo: Quick stream of the gallery via Miracast.

Active transmission of video stream over Wi-Fi significantly consumes the battery of the Redmi Note 7. Therefore, for long browsing sessions, it is recommended to keep the smartphone on charge, using a powerful power supply to compensate for energy costs.
