Modern users often wonder how to switch Xiaomi to HDMI to bring an image to the big screen.This may be required to watch movies, present work documents or run heavy mobile games. HDMI technology remains the standard for transmitting high-quality video and sound, and the Chinese manufacturer's devices are great friends with it.
However, the connection process is not always smooth. Owners of Mi TV Stick, Mi Box consoles or smartphones may experience a lack of signal, incorrect resolution or problems with sound. In this article, we will discuss in detail the physical aspects of connection, settings of the Android TV system and software broadcast methods.
It's worth noting right away that the way you approach the problem depends on the type of device you have built in. HDMI-Xiaomi smartphones do not have a port, so they use wireless protocols or special adapters. For TVs and consoles, the situation is simpler, but requires the correct configuration of ports.
Physical connection and cable selection
The first step is always to physically connect devices. If you use the Xiaomi Mi Box S or Mi console. TV Stick, you need to insert the device directly into HDMI-TV connector for stable operation 4K-It is critical to use a standard cable HDMI 2.0 or higher.
Cheap cables often fail to pass enough data, resulting in a flashing screen or no image at all. Make sure the cable sits tightly in the socket. Sometimes the problem lies in the length of the wire: for a distance of more than 3 meters, it is better to use active cables with amplification of the signal.
If you connect your laptop or PC to your Xiaomi TV via HDMI, first connect the devices with a cable, then turn them on. Android TV automatically recognizes a new signal source. In rare cases, manual switching of the signal source on the TV remote is required.
⚠️ Warning: Never connect or disconnect the cable HDMI, while the devices are plugged in, unless you're sure there's a power surge protection in your power grid. HDMI Supports hot-swap, static electricity can damage the controller.
After the physical connection, the TV must automatically go to the desired input. If this does not happen, use the source button on the TV remote and find the appropriate port.
Set up HDMI input on Xiaomi TVs
Once the device is connected, you need to make sure that the TV handles the incoming signal correctly. PatchWall interface or pure Android TV can hide some settings deeper than users expect. Go to the settings menu by selecting the gear icon in the upper right corner.
In the Settings section → The device → You can check the version of the system and update it. HDMI-The inputs are solved by updating the firmware. You can also find the image format settings here.
For gamers and PC users, it is important to configure port mode. In the Settings → Logins menu (or similar section depending on the version of MIUI for TV), you can activate HDMI 2.0 mode for specific ports to provide support for HDR and high frame rate.
If the image looks stretched or cropped around the edges, check the aspect ratio settings. Usually the automatic mode works correctly, but a manual 16:9 or Just Scan (by screen size) selection eliminates black bars.
Using Xiaomi Mi Box and TV Stick
The Mi Box and TV Stick devices are designed specifically to work over HDMI. Once connected to the port and powered (via USB or socket), they require initial setup. Choose a language, connect to Wi-Fi, and log in to your Google account.
The important step is to adjust the output resolution. The system usually determines the capabilities of the TV itself, but if necessary, you can go to Settings → Device → Settings → Display and Sound → Resolution. Here you should choose a mode that corresponds to your TV, for example, 4K 60Hz or 1080p.
☑️ Primary setup of the Mi Box
For users who want to stream a smartphone screen to a console, the built-in Cast function works flawlessly. Make sure the phone and console are on the same Wi-Fi network. In the phone notification curtain, select Translation and find your Mi Box.
Sound also requires attention. If you connect through HDMI, the sound continues to come from the TV, and you want to bring it to external acoustics through the optical output of the console (if any) or Bluetooth headphones, the settings are in the Sound section. HDMI usually has a rule: sound goes where the video goes.
Broadcasting the screen of the Xiaomi smartphone on the TV
Many users are looking for a way to switch Xiaomi to the new one. HDMI, I mean, wirelessly connected to a smartphone, because there's no physical connection to a phone. HDMI-port, using Miracast technology or Google Cast protocol.
In the MIUI or HyperOS shell, this feature is called Translation or Projection. Open the control center (swipe down from the top right corner) and find the Translation icon. The phone will start searching for available devices on the network.
An alternative is to use the Google Home app, which allows you to stream the screen to any Chromecast-enabled device, including Xiaomi TVs with Android TVs, which provides a more stable connection and lower latency.
⚠️ Note: In high-resolution wireless broadcasting (1080p There is a noticeable delay in input (input lag). For dynamic games, this method is not suitable, it is better to use a wired connection or streaming from a PC.
The quality of the image depends on the speed of the Wi-Fi router. 4K-5 GHz network is desirable in the frequency range of 2.4 GHz, jerks and compression artifacts can occur.
Problems with sound through HDMI
A common problem with connectivity is the lack of sound or poor quality. Android TV by default tries to match the sound format with the acoustics connected. If you use a soundbar or receiver, make sure that the Dolby Digital Plus or Pass-through format is selected in the audio settings.
In some cases, the system can't automatically switch to digital output. Go to Settings → Device → Settings → Display and Sound → Sound. Here you can force the output format from PCM to Bitstream (or vice versa), which often solves the problem of hissing or silence.
If you use a USB-C to HDMI adapter for your phone, remember that it must support audio transfer.Cheap Chinese adapters often only transmit video, leaving sound on the phone's speaker.
Why is there no sound in the apps?
For advanced users, there is a hidden section of the engineering menu where you can customize the audio stream in detail, but changing the parameters without understanding the consequences can lead to a complete loss of sound in the system.
Table of permission and frequency compatibility
Choosing the right resolution is critical for clarity, and here is a table that helps you determine the best settings for different use cases.
| Type of content | Recommended authorization | Frequency of update | Color format |
|---|---|---|---|
| Movies (4K HDR) | 3840x2160 | 60 Hz | RGB / YCbCr 4:4:4 |
| Games (Consoles/PC) | 1920x1080 or 4K | 120 Hz (if TV is supported) | RGB |
| Office work | 1920x1080 | 60 Hz | RGB |
| Old consoles. | 720p or 1080p | 60 Hz | YCbCr 4:2:2 |
Not all ports on Xiaomi TVs support maximum performance, and one port is usually labeled as HDMI (eARC/ARC) or has a special label to indicate support for high data rates.
When choosing a 120Hz frequency, make sure your cable is also certified for such speeds (HDMI 2.1).Using an older cable can cause the system to drop a frequency of up to 60Hz or lower.
Diagnostics and problem-solving
If the image is missing, the "No signal" sign is on or the screen is blinking, try rebooting both devices. Turn the TV off the outlet for 30 seconds to reset the residual charge and clear the cache HDMI-controller.
Check your energy saving settings. In some Eco modes, the TV may restrict power to the HDMI port, causing external devices to operate in an unstable manner. Turn off the energy saving modes in the Settings menu → System → Energy consumption.
💡
Use it. HDMI-A splitter with a switch button, if the TV has few ports but everyone is busy, it's cheaper than buying a new TV, and allows you to quickly switch between the PC and the console.
In complex cases, a complete reset of the image settings to factory settings helps, which returns all the color, brightness and signal format parameters to their original values, which often eliminates software conflicts.
If nothing helps, there may be a problem with the hardware of the port or the cable itself. Try connecting the device to another TV to prevent the signal source from breaking down.
💡
90% of HDMI problems are solved by replacing the cable with a quality certified analogue or reconnecting the power of the devices.
