The incorrectly tuned brightness on the Xiaomi Mi TV can ruin the viewing experience: too dim the screen tires the eyes, and excessive illumination leads to pixel burnout and increased power consumption. In this article, we will analyze all the available ways to adjust brightness, from basic settings through the remote control to hidden parameters for power users.

If you just bought a TV or noticed that the picture became uncomfortable for the eyes, do not rush to blame the manufacturer. 80% of the time the problem is solved by correct screen calibration, which can be done yourself in 5-10 minutes.
At the end of the article, you’ll find an FAQ with answers to frequent questions (such as why brightness is reset after switching off or how to calibrate the screen for games), as well as a table with optimal values for different use cases.
1. Quick brightness adjustment via remote control
The easiest way to change brightness is to use buttons on the remote, which works on all Xiaomi Mi TV models, including budget series without voice control.
Xiaomi has two key buttons on the remote:
- 🔅 Settings button (cog) – opens the main menu where you can find the Display and sound section.
- ☀️ Brightness button (sun) - direct adjustment of the backlight (not on all remotes).
If there is a button on your remote ☀️:
- Press it once and a brightness scale will appear on the screen.
- Use the Up/Down keys to change the value.
- Confirm the choice with the OK button.
If the buttons ☀️ no:
- Press Settings (cogs) → select Display and sound.
- Go to the submenu Brightness or Backlight (name depends on the model).
- Adjust the slider manually.
⚠️ Note: On some models (e.g. Mi) TV 4S 55") button ☀️ There is no remote, but the brightness can be changed through Quick settings - hold the Home button (house) for 2 seconds.
2. fine tuning through the TV menu
For more accurate brightness calibration, go to the advanced settings, where you can adjust not only the general illumination, but also contrast, gamut and color temperature, which is especially important for moviegoers and gamers.
Instructions for all Xiaomi Mi TV models (including Mi TV Q1E, Mi TV A Pro):
- Open the settings (cog on the remote).
- Select the display and sound → Picture.
- Go to the Additional or Expert Settings section.
- Adjust the parameters: 🌡️ Brightness – the overall screen illumination (40-60% is optimal for home use). 🔄 Contrast – the ratio of light and dark areas (recommended 80-90%). 🎨 Color temperature – “Warm”, “Standard” or “Cold” (for eyes it is better “Warm"). 🔍 Local dimming – improves black color (available on Full Array Local Dimming models).
On Xiaomi TVs with a MediaTek 9650 processor (such as the Mi TV Q2 75), there is a hidden Mode Mode "Cinema" on the menu, which automatically optimizes brightness for dark scenes. To activate it, go to Picture → Modes → Modes → Movies and turn on the Dynamic Contrast option.
Brightness: 45-55%
Contrast: 85-90%
Color temperature: Warm
Local dimming: On.
Picture mode: Movie-->
| Use case scenario | Brightness (%) | Contrast (%) | Color temperature | Recommended treatment |
|---|---|---|---|---|
| Watching movies in a dark room | 30–40 | 80–85 | Warm. | Cinema. |
| Games (console/PC) | 60–70 | 90–95 | Standard. | Game. |
| Day viewing (sunshine) | 70–80 | 85–90 | Cold. | Dynamic. |
| Work with text (browser, documents) | 50–60 | 75–80 | Warm. | Standard. |
3. Automatic brightness control (illumination sensor)
Xiaomi Mi TV Pro and some Q series models come with an ambient light sensor that automatically adjusts brightness based on the lighting in the room, a feature that is useful if you watch TV at different times of the day, but sometimes it works too aggressively.
How to adjust or turn off automatic brightness:
- Go to Settings → Display and sound → Picture → Additional.
- Find the option Automatic brightness or Adaptive backlighting.
- Choose one of the options: 🔄 Incl. – the brightness will change automatically (may cause flickering). 🚫 Hand-held configuration (recommended for stability). ⚙️ Customization – some models allow you to set a range of changes (for example, from 30% to 70%).
⚠️ Attention: The light sensor can trigger reflections from windows or lamps, which will cause brightness to "jump" even in static light. If this interferes, turn off the function or seal the sensor (usually located on top or bottom of the frame) with opaque tape.
On models without a sensor (such as the Mi TV 4A), the automatic adjustment is time-of-day.
- Open Settings → System → Time and Date.
- Make sure Auto Update Time is enabled.
- Return to Display and Sound → Picture and activate Night Mode (reduces brightness and blue light in the evening).
💡
If the automatic brightness is not working correctly, reset the sensor settings: go to Settings → Applications → System applications → Sensors and select Reset Calibration.
4. Brightness adjustment via voice assistant
Xiaomi TVs with Google Assistant or Alice (in Russian models) allow you to control the brightness of your voice. This is convenient if the remote is lost or you want to quickly adjust the screen to the current conditions.
Voice control methods:
- 🎤 Through the microphone remote: Press and hold the microphone button (🎤) Tell the command, "Put 50 percent brightness," or "Make the screen brighter".
- 📱 Through the Mi Home app: Open the app and select your TV. Click on the microphone icon in the top right corner. Say the command: "Brightness 70".
Google Assistant
on a smartphone:
- Activate the voice assistant on your phone (e.g., say “OK, Google”).
- Say, “Set the brightness on Xiaomi TV at 40%.”
Voice commands support the following parameters:
After the reset, we recommend:
- 🔧 Select the picture mode depending on the use (for example, Standard for everyday viewing or Movie for movies).
- 📏 Calibrate the brightness for the lighting in the room (see the table in section 2).
- 🔄 Check if the automatic brightness is turned on (if it interferes with the lighting).
If the reset didn't work and the picture remains bad, there may be a problem with the hardware (e.g., backlight burnout).
