Xiaomi’s modern Smart TVs often come with factory settings that focus on display in stores rather than comfortably viewing at home. The image may seem too bright, scorched, or dim in the dark, because manufacturers set maximum lighting values to make the picture look spectacular in bright lighting of shopping halls.
For a user who is first exposed to an Android TV or PatchWall interface, finding the right sliders can be a real puzzle. The menu of image settings is hidden, and automatic modes often work incorrectly, changing parameters on the fly. Proper screen calibration is not just aesthetics, but also concern for eye health, especially when watching movies for a long time.
In this article, we’ll look at all aspects of your display settings, from basic brightness and contrast sliders to advanced settings like local dimming and color temperature, and learn how to tailor your image to the specific lighting conditions in your room and get rid of image artifacts.
⚠️ Note: Before making changes to the image settings, it is recommended to take a picture of the current parameters on the phone, which will allow you to quickly return to the original settings if the calibration result does not suit you.
The first step to getting the picture perfect is through the standard system settings menu. Xiaomi TV remotes usually have a dedicated button, often marked as Menu or gear icon, and clicking on it causes a quick menu where you can find the visuals section.
In the window that opens, you need to find Settings (the gear icon) and then go to Image or Screen and Sound. That's where the basic controls for image quality are. The interface may vary slightly depending on the version of the MIUI for TV firmware, but the logic remains the same for all models.
The main parameter we're interested in is called Brightness, but it's not to be confused with Contrast, which regulates the overall intensity of the matrix, while contrast is responsible for the difference between the darkest and the brightest areas of the frame.
To start, try to switch the image mode. Standard profiles like Bright or Dynamic often sin with unnatural colors and excessive glow. Switching to Movie, Standard or Custom modes will immediately make the picture softer and more pleasing to the eyes.
Difference Between Brightness, Contrast and Backlighting
Many users mistakenly believe that all three factors affect the same thing. This misconception leads to the image either fading or losing detail in the shadows. Understanding the physics of the process will help you customize your Xiaomi TV as accurately as possible.
Brightness/Backlight is the intensity of the LEDs behind the array. By increasing that, you make the entire screen lighter, including black colors that can turn gray. On Xiaomi TVs, this is often a range of 0 to 100.
Contrast determines how white is compared to black. High contrast makes the image clear, but if you go too far, the details in the light areas disappear (the “light” effect). Low contrast makes the picture flat and pale.
- 🌞 Brightness: regulates the total power of the screen backlight.
- ⚖️ Contrast: Difference between darkest and lightest points.
- 🌑 Local dimming: technology for controlling LEDs in individual areas of the screen.
A third important feature that is often found in advanced settings is Local Dimming, which allows the TV to independently control the brightness of individual areas of the backlight, so if the frame is dark at night and bright moon, the TV will diode the sky and light them in the moon.
⚠️ Note: On budget Xiaomi TVs, the local dimming function may not work properly, creating noticeable halos around bright objects. If you see such artifacts, try turning this option off.
Technical details of the matrices
Xiaomi TVs use IPS and VA matrices. VA matrices have better native contrast and deep black, but smaller viewing angles. IPS matrices give a more stable color reproduction at an angle, but black color on them often looks grayish, especially when the backlight is high. Understanding the type of your matrix will help you choose the right balance of settings.> Extended options: color, temperature and gamma After settings are set, it is worth looking at the extended menu. Here are the tools for fine-tuning color reproduction. The color temperature parameter (Colature is recommended for the default mode, which is the color mode for the viewing of the picture, which is not comfortable). This will bring the color closer to the standard of cinemas. Gamma affects the brightness of the middle tones. Gamma changes don't affect pure black or pure white, but changes the saturation of the semitones. If the image seems too dark in the middle tones, try changing the gamma value from the color of the color. 2.2 on 2.0 or 1.8. Parameter Recommended value Impact on image Color temperature Warm / Warm 2 Remove the blue, makes the colors more natural Gamma 2.2 (Standard) Brightness balance in medium tones Dynamic contrast Off/Low Automatically changes brightness, can distort the movie Noise Reduction Off (for HD/4K) It removes graininess, but it can blur details, and it's also worth paying attention to Dynamic Contrast, which tries to automatically adjust brightness based on the content of the frame. While this sounds useful, in practice the feature often works aggressively, causing noticeable brightness spikes that distract from viewing. Automotive modes and light sensors Many Xiaomi models are equipped with light sensors that automatically adjust the brightness of the screen depending on the light in the room. The feature can be called Eco Mode, Automatic Brightness or Light Sensor. In theory, this is a great feature: the screen becomes brighter during the day so that the picture does not fade, and at night it does not blind the eyes. However, in practice, the TV can darken the screen during the brightness of the movie, if you notice that the main part of the movie, or add the light. To obtain a stable and predictable image, it is better to turn off automatic adjustment and set a static value that is comfortable for your conditions. Customization through third-party apps and calibrators For advanced users who don't have enough standard settings, there are ways to deeper calibrate.As Xiaomi TVs run on Android TV, And you can use these to install specialized applications to calibrate images, and one of the popular methods is to use test images. You can download a set of calibration tables (for example, from the Disney World of Wonder package or free analogues) and, by playing them, adjust the brightness and contrast “by eye”, based on visual landmarks. There are also applications that allow you to manage parameters through an engineering menu or ADB (Android Debug Bridge). Connecting to a TV over a network from a computer gives access to hidden settings that are not output to a normal user interface. 📱 Calibration applications: help to adjust colors to the reference. 💻 ADB commands: allow you to change the hidden parameters of the system. 🎨 Test images: visual tool for adjusting gradients, but be careful: changing hidden parameters through the use of a gradient. ADB This method can lead to unstable system operation, and only use it if you are confident in your actions and understand what each parameter is responsible for. ⚠️ Note: Making changes through the engineering menu or ADB You can cancel the warranty, you can be very careful when you type commands and change the system files on the display configuration, so you can solve why the settings are getting lost? Sometimes users are faced with a situation where the tuned brightness spontaneously resets or changes after the TV is restarted. This can be caused by a firmware update that returns the settings to factory settings. Another reason is the activation of energy-saving modes. System settings General -> Eco mode can be ticked off to automatically dim the brightness to save energy, and turning it off will put control of the image settings back in your hands, and if the problem persists, it could be a malfunction of the light sensor or a software failure. In this case, a complete reset of the TV settings to factory settings can help, but remember that this will delete all your data and installed applications (FAQ) Why Xiaomi TV doesn’t have a brightness slider in some apps? This is normal behavior when reproducing. HDR-content or when using some embedded applications. HDR The brightness and contrast are automatically controlled by the video stream and the TV to meet the standards, and the manual adjustment is blocked by the system at this point, and how do I get back to the factory settings of the image if I messed up? The image settings menu usually has a Reset or Default button (often in the corner of the screen or in the submenu) and clicking on it will return all brightness, contrast and color parameters to factory values for the current selected mode (for example, Standard). Yes, Game Mode often has its own brightness and contrast, optimized for fast matrix response. In this mode, some post-processing features can be disabled, making the image less “processed” visually, but more responsive. Can you adjust brightness through the Mi Remote app on the phone? Direct brightness adjustment through the standard Mi Remote app (as done with volume) is usually not. However, you can use the phone as a touchpad to navigate the TV settings menu, which is sometimes more convenient than poking buttons on the remote.
