Xiaomi and Redmi smartphones today have powerful cameras that allow you to take high-resolution images, but the screen diagonal often limits the enjoyment of viewing. Showing a family album or a trip report on a large TV screen makes this process a real event for everyone. In the Mi Home ecosystem, there are many ways to accomplish this task, from simple wireless protocols to wired connections.
The choice of method depends on the model of your TV, the version of the Android operating system or MIUI, and the availability of certain applications. Some methods allow you to transmit static images, others provide a full screen broadcast in real time, understanding the technical nuances will help to avoid delays and loss of quality when displaying images.
In this article, we will take a look at all the current methods of connection, compare their effectiveness and look at the typical errors that users encounter, you will learn how to set up a connection in a few minutes and enjoy content without unnecessary wires and complex router settings.
Preparation of equipment and basic requirements
Before you start setting up a broadcast, you need to make sure that all devices are ready to interact. The fundamental condition for most wireless methods is to find a Xiaomi smartphone and a TV on the same local Wi-Fi network. If the router distributes a network at 2.4 GHz and 5 GHz, make sure that both gadgets are connected to the same frequency, since some casting protocols do not see the devices on different subnets.
It’s also worth checking out the software version on your TV. Smart TVs from Samsung, LG, Sony or Android TV should have updated firmware to properly operate Miracast or DLNA protocols. On your Xiaomi phone, make sure geolocation and Bluetooth services are enabled in the settings, as they are often used to initially detect nearby devices.
⚠️ Note: If your router is set up with customer isolation (AP Isolation, wireless data transfer between the phone and the TV will not be possible, and this feature is usually disabled in advanced router settings.
For stable transmission of high-resolution photos, especially in RAWHEIF format, it is recommended to use a network with a bandwidth of at least 20 Mbps. Overloading the channel with other devices can cause artifacts or long delays when flipping slides.
☑️ Checking before connection
Use of the built-in Translation (Miracast) function
The fastest way to display an image is to use the native MIUI feature, which is based on the Miracast standard, which requires no third-party software installation and works on most modern Smart TVs. To run, you need to lower the notification curtain and find the Translation or Cast icon. If the icon is not present, you can add it through the Control Panel editing menu.
Once activated, the phone will start looking for available displays, the list should show compatible TVs, when you select a device on the TV screen, you may request a connection confirmation, which you need to accept by the remote, and then the phone screen is completely cloned onto the TV, allowing you to open the gallery and flip through the photo.
Miracast image quality depends on the Wi-Fi module power and the distance to the router. When viewing a photo in high resolution, you can experience a slight compression of the image, but this is usually enough to show a slide show.
Why is there no sound when broadcasting the photo?
Mi Remote app and Mi TV ecosystem
Owners of Android TVs or devices with support for the Xiaomi ecosystem can use the Mi Remote app (Mi Remote), which is built into most MIUI and HyperOS shells, and this tool allows you not only to control the volume, but also to transfer media files directly from the gallery.
To work, you need to link your phone and TV through your Mi Account or scan QR-The code that appears on the TV screen in the Media Player app, and when paired, the phone gallery will have a "Translate" button (TV icon) that allows you to send the selected photo to the big screen.
- 📱 Open the gallery and select the photo you want.
- 📺 Click the broadcast icon in the lower menu.
- 🔗 Select your TV from the list of devices.
- ▶️ The image will appear on the screen, leaf control is possible from the phone.
The advantage of this method is that it supports 4K format and a more stable connection compared to the universal Miracast. In addition, the application allows you to create playlists of photos that will be played in a given order.
💡
If the phone doesn't see the TV in the Mi Remote app, try restarting the router. Often the problem lies in the cache. DNS-A router server that does not update the list of local devices.
Using the Google Home app for Chromecast
For TVs with built-in Chromecast or connected Google Chromecast, the official Google Home app is the ideal solution, which provides minimal latency and high image quality, since the TV itself downloads content from the link transmitted by the phone, rather than receiving a video stream.
In the Google Home app, you need to find your TV in the list of devices. After you log in to the control menu, select the option “Translate screen” or use the streaming function directly from the Google Photos app if your pictures are synced with the cloud. Google Cast protocol is highly energy efficient for a smartphone.
A feature of the method is that it can be used for other tasks during the slideshow, and unlike Miracast, the phone acts as a remote control, and the main work of decoding and rendering is done by the TV processor.
Wired connection via HDMI and USB
When the wireless network is unstable or requires the transfer of photos in the original quality without compression, the best choice is a cable connection. For Xiaomi phones with a USB Type-C port that supports the USB 3.1 standard or higher, you can use a USB-C to HDMI adapter.
After connecting the cable to HDMI-the input of the TV and the selection of the appropriate signal source (Source) → HDMI 1), the image from the phone is automatically duplicated onto the screen.This method ensures no delays and maximum resolution supported by the TV matrix.
If your phone does not have video support USB (It is often used in Redmi budget models, you can use it. OTG-Connect the flash drive to the phone, copy the photo, and then insert the flash drive into the phone. USB-TV port. Built-in media player TV It will allow you to open files and launch a slideshow.
💡
Wired connection via HDMI is the only way to ensure that photos are transmitted in 100% original quality without compression artifacts typical of Wi-Fi protocols.
Third-party applications for media broadcasting
If standard tools don’t work or the functionality isn’t enough, specialized applications from Google Play come to the rescue. Leaders in this category are LocalCast, AllConnect and BubbleUPnP. These programs are able to find DLNA-compatible devices of almost any brand.
Apps allow you to flexibly configure display settings, create playback queues, and even broadcast photos with subtitles or music, some of which support transcoding on the fly, converting formats that the TV doesn't understand into compatible formats.
Installing such software is justified if you often show content on different TVs (guests, in the office), Universal players often have a more convenient interface for managing large photo libraries than the standard MIUI gallery.
Comparison of connection methods
To choose the best option, it is important to compare the specifications of each method. Below is a table that helps you determine the way you connect depending on your priorities: speed, quality or convenience.
| Method | Quality. | Delay. | Convenience |
|---|---|---|---|
| Miracast (Translation) | High. | Low. | Maximum. |
| Google Chromecast | Very high. | Minimum | High. |
| HDMI Cable | Perfect. | Absent. | Low (need cable) |
| DLNA (Annexes) | High. | Medium | Average. |
For a quick show of a couple of pictures to friends, the built-in Translation feature is enough. If you plan a long slideshow at an event, you should use a Chromecast or wired connection for reliability.
Remember that the quality of the Wi-Fi signal directly affects the speed of uploading photos to the TV buffer. When using streaming methods, a weak network can lead to the appearance of “squares” or long waits.
Frequent problems and their solution
Even if you set it up properly, it can be difficult. One of the common problems is that the phone sees the router, but it doesn't see the TV on the list of available devices. In this case, check if the router has a guest network on one of the devices. The devices on the guest network are isolated from the main LAN.
Another common case is codec desynchronization, if the TV says "Format not supported", try changing the format of the photo on your phone (for example, from HEIC to JPG) before transfer, and installing codecs on Android TV through third-party players like VLC also helps.
⚠️ Note: When using adapters HDMI Older TV models may not have enough power. USB-Use an adapter with additional power or connect the phone to the charger.
If the image twitches or is interrupted, try to approach the router or switch the Wi-Fi frequency from 5 GHz to 2.4 GHz for greater range, although the speed may drop. Sometimes it helps to simply restart the Wi-Fi Display service in the phone's settings.
