How to set up the lighting on the Xiaomi TV

Owning a modern Xiaomi Mi TV or Redmi TV involves not only access to streaming services, but also the ability to fine-tune the image for maximum eye comfort. Many users immediately notice that the standard picture looks unnaturally bright or, conversely, too dark in the evening, this is due to factory settings, which are often focused on the demonstration mode in electronics stores, rather than home viewing.

Correct adjustment of screen parameters allows to significantly improve color reproduction, reduce eye fatigue during long-term viewing and even extend the service life. LED-In this article, we will discuss all the available ways to control brightness and contrast, including hidden engineering menus and standard settings of the Android operating system. TV.

Proper calibration is the balance between power consumption and image quality. Brightness and contrast are the basic parameters that affect the perception of depth in black and detail in light areas of the frame. Ignoring these settings can lead to the fact that you will not see all the benefits. HDR-content or quality 4K-picture.

Basic image settings in the TV menu

The first step to getting the picture perfect is to go to the standard operating system interface. On Xiaomi TVs running Android TV or PatchWall, the path to settings may vary slightly, but the logic remains the same. You need to get into the section where the parameters of the video output are adjusted.

To access the basics, use the remote control. Press the menu button or go to the top right corner of the screen where the gear icon is located. This is the global settings of the system, including sound, network and image management.

⚠️ Warning: Do not set the brightness value to 100% immediately after turning on the TV. LED-Cold-condition diodes can reduce their lifespan.

Inside the Image or Picture section, you'll find manual sliders, and the system offers several preset modes, such as Standard, Movie, Sport and Game, each already containing a basic backlight profile that can be adjusted.

• 📺 Mode Mode – usually has a warmer color temperature and moderate brightness, which is ideal for watching movies under artificial lighting.
• 🎮 Game mode – often characterized by increased brightness and color saturation for better visibility of details in dark scenes of games.
• 🌤️ Standard Mode – a universal profile with a balance between brightness and color reproduction, suitable for day viewing.

It is important to understand the difference between Brightness and Backlight on some models menus. In Xiaomi TV terminology, the Brightness slider often adjusts the level of black (makes dark areas lighter or darker) rather than the light intensity. The glow strength of the matrix can be called simply “backlighting” or adjusted using the Energy Saving parameter.

Adjustment through the remote and quick settings

Xiaomi’s TV operating system allows you to change key image settings on the fly without interrupting your viewing content. This is especially convenient when you switch between bright daytime and evening thriller watching in the dark. Quick access is via the Quick Settings menu.

Press and hold the menu button on the remote or swipe down (if the remote is used) to trigger the notification curtain. This often provides access to image modes. If there is no such button, you can use a combination of buttons to call the audio and image settings menu.

Click the button "Menu" → Select "Imaging Settings" → Slider adjustment

Using fast settings allows you to quickly respond to changes in lighting in the room, for example, you can add brightness during the day to compensate for the glare from the sun, and at night to reduce it to a minimum for eye comfort.

💡

Use voice search on the Xiaomi remote by saying “Imagine settings” to instantly navigate to the desired menu section without a long browse.

Some Bluetooth remotes have a dedicated button to call the settings menu, in which case a short-term tap can trigger a list of signal sources, and a long-term tap can open the system settings. Experiment with the duration of the tap to find a convenient way to control.

It is worth noting that the changes made through quick settings apply globally to all signal sources, unless the smart image feature is activated, which can automatically switch profiles depending on the type of content (TV channels, YouTube, Netflix).

Use of Eco mode and light sensors

Modern Xiaomi and Redmi TVs have energy-saving features that directly affect the operation of backlighting. Eco or Eco Mode automatically limits the maximum brightness of the matrix to reduce power consumption.

Activating this mode can be useful for permanent use if you're environmentally conscious or want to reduce your electricity bills. HDR-High quality content is better to turn off this mode, as it does not allow you to reveal the dynamic brightness range.

Auto Brightness uses a built-in light sensor. The TV analyzes the amount of light in the room and adjusts the glow of the screen. This is convenient, but sometimes the algorithms work incorrectly, making the picture too dim when watching night scenes in the movies.

⚠️ Attention: The light sensor can respond to light from the screen itself or the desk lamp, causing the image to “breath” when the brightness is constantly jumping.

If you notice unstable brightness behavior, check the sensor settings in the General or System menu, which can often be adjusted to sensitivity or completely disable automatic correction by switching to manual control.

Extended calibration and color spectrum

For users who want to achieve maximum color accuracy, Xiaomi TVs offer advanced settings that allow you to adjust not only the overall brightness, but also individual color channels, gamut and color temperature.

These settings are usually hidden under the "Advanced" or "Professional settings" submenu, and you can find Gamma, Color Temperature and Dynamic Contrast settings here, and you need to be careful about changing these values, because the wrong settings can distort colors beyond recognition.

• 🎨 Color temperature – switches the balance between cold (bluish) and warm (yellowish) shade of white.
• 📉 Gamma – affects the brightness of the average tones; changing this parameter makes the image flatter or more contrasting.
• 🌑 Local dimming is a technology that allows you to independently control the brightness of different parts of the screen for deep black color.

When adjusting the color spectrum, it is recommended to use special test images or video samplers, which can be found on YouTube or downloaded via USB, to help visually assess whether details are lost in shadows or lights.

Remember, the eyes have a tendency to adapt. What seemed perfect in the first 5 minutes of setting up, after an hour, may look too yellow or blue. Take breaks when calibrating to "reset" the perception of colors.

Engineering menu and hidden parameters

For advanced users, there is access to the engineering menu of Xiaomi TVs, a hidden part of the system designed for service engineers, but accessible to ordinary users, and accessed through special combinations of buttons on the remote or through terminal applications.

One way to log in is to use the Remote ADB app or similar Android TV utilities by connecting to your TV from a computer or smartphone, and you can enter codes to access service menus through the command line.

adb shell am start -n com.android.tv.settings/.EngineeringModeActivity

In the engineering menu you can find a parameter Panel_Usage_Time (The panel's running time) and the lighting driver settings. There's also white balance calibration by point (2-point and 10-point white balance, which allows you to achieve a reference picture.

Be very careful. Changing values that you're not 100% sure of can disrupt the matrix. Unlike the regular menu, there's no "Reset All Settings" button to return to factory values of specific driver parameters.

If after experiments in the engineering menu, the image became incorrect, the only way out is often a complete reset of the TV to the factory settings (Factory Reset) through the recovery menu (Recovery Mode).

Resolving Uneven Lighting Problems

One of the common problems LED-TVs, including budget models Xiaomi and Redmi, are uneven backlighting, manifested in the form of lights on the edges of the screen (clouding) or darker spots in the center.

Part of the solution is software-based, with the optimal brightness level, which always increases the visibility of the lights, and reducing this to 60-70% often makes the defects less noticeable, especially in the dark.

⚠️ Attention: Mechanical pressure on the screen to warm up the matrix is strictly prohibited. This will lead to broken pixels and rupture of plumes.

It’s also worth checking if dynamic backlighting is on, which can create the illusion of unevenness when displaying static dark scenes. Disabling all image “improvers” helps to reveal a real physical defect of the panel or software glitch.

If the lights are only visible on a black background and not visible when viewing regular video content, this is a feature of LED technology, not a defect.

💡

Software settings can hide small backlight defects, but will not eliminate the physical flaw of the matrix.

In cases where backlight defects interfere with normal use of the device and are visible with any content, it is advisable to contact the service center under warranty, especially if the TV is less than a year old.
