Owners of modern Xiaomi Mi TVs often face a situation where the image quality when viewing content in 4K seems not bright enough or saturated. This is because by default, the technology of extended dynamic range may not be activated or work incorrectly due to port settings. HDR (High Dynamic Range) is a standard that significantly expands the range of brightness and color reproduction, making the picture as close to reality as possible.
To access this functionality, the user needs to not only find the switch in the menu, but also make sure that the external source of the signal is compatible. Often the problem lies in the HDMI cable or the firmware version of the Android TV system. In this article, we will discuss in detail the algorithm for activating the function.
Note that format support depends on your device’s specific model. Budget versions can only support basic HDR10, while flagship Master or QLED models also work with Dolby Vision.
Checking the compatibility of equipment and content
Before you go into system settings, you need to make sure your hardware is physically capable of displaying extended dynamic range. HDMI-The ports on Xiaomi TVs are the same: some support the full bandwidth required for the new model. 4K HDR, others are limited.
Note the port marking on the back of the device. Usually, ports that support HDCP 2.2 and high bandwidth are labeled or colored. Using an inappropriate HDMI cable that is not certified for High Speed will also cause the TV to fail to switch to the desired mode.
⚠️ Note: If you are using an old cable HDMI, Buying more than 5 years ago, it may not miss a signal 4K HDR, Even if the TV itself supports it, replace the cable with a certified one. HDMI 2.0 or HDMI 2.1.
It is also important to make sure that the signal source (game console, console or PC) is configured to output the image in the correct format. Often in the settings of the PlayStation 5 or Xbox Series X, you need to manually select the color format RGB or YUV 4:4:4 and the color depth of 10 bits.
- 📺 Make sure your TV model supports the standard. HDR10 Or Dolby Vision.
- 🔌 Use it. HDMI-cables labeled "High Speed" or "Ultra High Speed".
- 🎮 Check the image output settings on the external console or PC.
Only if all these conditions are met will the software activation of the function give a visible result, otherwise the TV will work in standard SDR mode, limiting the color gamut.
Activation of the extended HDMI format in settings
The most critical step is to enable an extended format for a specific HDMI port. In the Android TV operating system installed on Xiaomi Mi TV, by default, ports can work in compatibility mode, which blocks HDR.
To change this, go to the main menu and select the settings section. You need to find the inputs and external devices. The path may vary slightly depending on the shell version, but the logic remains the same.
☑️ Checking settings HDMI
Once the Advanced Format option for the respective port is enabled, the TV will reload the video stream, a step that is mandatory for HDR to work on HDMI ports 1 and 2, as bandwidth is limited without it.
If the option is not available to select (gray), this means that the current resolution or refresh rate does not allow you to turn on the extended mode.
Setting up the image and viewing modes
After the technical activation of the ports, you need to adjust the image itself. Standard modes, such as Standard or Bright, often do not use the full potential of HDR. For best quality, it is recommended to switch to Movies, Movies or special mode HDR Video.
Additional settings are available in the image menu, such as dynamic contrast and local dimming. On models with QLED or Mini-LED matrixes, these settings play a key role. You should not twist all parameters to the maximum, as this can lead to lights and loss of detail in the shadows.
| Parameter | Recommended value | Impact on HDR |
|---|---|---|
| Brightness | 80-100% | Critical for peak brightness |
| Contrast | 90-100% | Determines the depth of black |
| Dynamic contrast | Off/Middle | Could distort the colors. |
| Noise suppression | Off | Save details in 4K |
| Color temperature | Warm 2. | More accurate color reproduction |
Experts recommend using calibration videos available on YouTube or Netflix to visually evaluate the result.The image should be natural, without unnatural re-lighting in light areas.
Solving problems with dim image in HDR
Many users complain that after the inclusion HDR It gets dull and faded. This is a common problem with tonal compression. Xiaomi's TV is trying to display a very bright image. HDR-signal on a screen that cannot reach peak brightness of 1000 nits.
This results in dynamic range compression algorithms that reduce the overall brightness to preserve the details, and the solution may be to turn off Eco Mode or Automatic Brightness Adjustment in the system settings.
Why do the colors turn pale?
It's also worth checking the HDMI settings on the external device, for example, on Xbox, you need to go to the video settings and make sure that the "Allow 4K" and "Allow HDR10" check boxes are ticked, sometimes resetting the image settings to factory values with manual adjustments.
If the problem persists, try updating the TV's firmware. Xiaomi engineers regularly release updates that improve video processing algorithms and fix compatibility errors with game consoles.
Features of working with game consoles
Gamers using Xiaomi Mi TV alongside PlayStation 5 or Xbox Series X should pay special attention to refresh rate.HDR support at 60Hz and 120Hz requires maximum channel bandwidth.
In game mode, additional features such as ALLM (Auto Low Latency Mode) and VRR (Variable Refresh Rate) are often automatically enabled, which can conflict with HDR settings on some TV models, causing the signal to flicker or disappear.
- 🎮 For games, it is more important to use the port. HDMI 2.1 if marked as Game Mode.
- 📉 If you have problems, try to reduce the frame rate to 60 Hz in the console settings.
- 🔧 Turn off intermediate devices such as soundbars or receivers for direct connection.
⚠️ Attention: When in use AV-between the console and the TV, make sure the receiver also supports passthrough. HDR10 And Dolby Vision. Older models can cut the signal.
Proper setting of the game mode allows you to enjoy not only high frame rate, but also a rich color palette, which is especially important in story games with a well-developed visual range.
Using applications for verification and testing
To make sure that all settings are applied correctly, use specialized applications. In the Google Play store on the TV, utilities for testing the display are available.
One of the best ways to check is to run content on streaming services. Netflix, Amazon Prime Video and Disney+ have special test videos. When playing such a video, the format logo should appear on the screen (for example, "Dolby Vision" or "HDR10").
If the logo doesn't show up, it means that the signal chain is broken somewhere, it can be a software failure, it can be a physical cable malfunction, and there are test table generator applications that help adjust the white balance.
Regular image quality checks will help you notice the degradation of the cable or the need to update the TV software.
