Adaptive backlighting in Xiaomi TVs: a full guide to technology 2026

When it comes to modern TVs, the term adaptive backlighting is increasingly common — especially in the context of premium Xiaomi models. But what is behind this technology? Why is it considered revolutionary for image quality, and is it really worth overpaying for a TV with this feature? If you're looking for a new TV or just want to understand the technicalities, this material will help.

Responsive lighting (or local dimming) is not just a marketing ploy; it's a real-world technology that dramatically changes the perception of contrast, black, and overall depth. Xiaomi TVs have it implemented in different ways, from low-end zone-lighting solutions to flagship models with thousands of independent LEDs, and we'll take a look at how it works, which models support the function, and whether it should be activated for movies, games, or everyday use.

It’s important to understand that responsive lighting isn’t a universal solution for all scenarios; in some cases, it can even make perceptions worse (e.g., when viewing content with fast scenes or in a brightly lit room). So at the end of the article you will find practical recommendations on how to customize it to your needs, as well as comparisons with alternative technologies, such as: OLED or QLED.

What is adaptive backlighting and how it works in Xiaomi TVs

Local dimming is a technology for controlling LEDs behind a TV array, and unlike traditional backlighting, where all LEDs work in synchrony, they're divided into independent zones, each of which can adjust the brightness separately, which allows you to:

• 🌑 Deepen black: In dark scenes, the LEDs in the respective zones go out completely, creating a “true black” effect».
• 💡 Increase contrast: bright objects (such as car headlights at night) look juicier against a dark environment.
• 🎭 Improve detail: in the halftones and shadows appear small details that are lost when the lighting is uniform.

In Xiaomi TVs, adaptive lighting is implemented on the basis of LED-Zone-controlled matrices: The number of zones varies from model to model: from 16-32 zones in budget series (e.g. Mi). TV Q2) 1,000+ Microzone in flagships (for example, Xiaomi) TV The more zones, the more accurate the control over the picture, but the higher the price of the device.

But the technology has limitations, for example, if you display bright and dark objects in the same backlight zone at the same time, you can have a bloating effect, and manufacturers are struggling with this with image processing algorithms, but you can't completely eliminate the artifact yet.

Xiaomi models support adaptive lighting in 2026

Not all Xiaomi TVs are equipped with adaptive backlighting – this feature is found mainly in the mid- and premium segments. Below is the current table of models with support for the technology (data for the first half of 2026):

Note that even within a series, the number of zones may vary depending on the diagonal. TV Q2 The 55 Pro has 96 zones, and the 75 has 128, which is due to physical limitations: you can make bigger zones on big screens without losing accuracy.

It is also important to note that the adaptive lighting system works more efficiently. VA-Matrices (with better contrast angles) than on the IPS. For example, the Redmi Smart TV X Pro with 16 zones may perform worse than Xiaomi TV A Pro with 32 zones, due to differences in matrix types.

⚠️ Note: In budget models (e.g. Redmi Smart) TV A) the adaptive backlight function can be disabled by default. To activate it, go to Settings → Picture → Additionally. → Local blackout.

Advantages and disadvantages of adaptive lighting in Xiaomi TVs

Like any technology, adaptive lighting has its pros and cons, and let's look at Xiaomi TVs, where it's most vividly implemented.

Pros:

• 🎬 Cinematic experience: Ideal for watching movies in a dark room – black becomes really deep and scenes with high dynamic range (HDR) look bigger.
• 🔍 Details in the shadows: Dark scenes (such as space scenes or night shootings) show details that are lost on uniformly illuminated TVs.
• 💰 Price availability: unlike the OLED, Xiaomi TVs with adaptive backlight are much cheaper with comparable black quality.

Cons:

• 🌞 Artifacts in bright light: in sunny weather or with light on, the effect of the technology is reduced to zero - the backlight zones become noticeable.
• 🎮 Delays for gamers: Image processing algorithms can add 10-20 ms input lag, which is critical for competitive games.
• 🔄 Blooming effect: around bright objects on a dark background, a light halo appears, especially noticeable in budget models with a small number of zones.

Interesting fact: in flagship models (for example, Xiaomi) TV Master Ultra is used by Mini LED-It's a lighting system with thousands of micro-zone lights, and it minimizes the effect of the blooming, but it's a TV that costs about as much as the average. OLED-So before you buy, you have to weigh what's more important: the perfect black (OLED) high brightness and no risk of burnout (Mini) LED).

💡

If you often watch subtitled content, adaptive lighting can create discomfort: bright letters on a dark background will “light up” neighboring areas, in which case try to reduce the number of zones in the settings or turn off the function altogether.

How to set up adaptive lighting on Xiaomi TV

By default, adaptive lighting is not always on, and its parameters may not be optimal. To customize the function to your needs, follow this instruction:

1. Open the settings (cog on the remote or in the upper right corner of the screen).
2. Go to the Picture section. → Additionally.
3. Find Local Dimming (or Local Dimming in English firmware).
4. Select one of the modes: Off – backlight works evenly; Low – minimal aggressiveness of algorithms (suitable for day viewing); Medium – balance between contrast and artifacts; High – maximum depth of black (optimum for a movie in the dark).

For fine tuning, it is recommended:

• 📏 Calibrate the brightness: in the menu Picture → Brightness set the value 45-55 (for HDR-content - 70-80).
• 🎛️ Set up the scale: optimal value - 2.2 (in the menu Additional) → gamma).
• 🔄 Disable energy saving: Eco-mode or Adaptive brightness may interfere with local dimming.

Set Local Dimming Mode to "High"|Deactivate "Dynamic contrast"|Activate Dolby Vision (if supported)|Put the scale on 2.2.|Deactivate "Eco-regime"-->

If the image appears too dark after setting up, or if artifacts appear, try reducing the number of active zones. TV Q2 Pro) there is a hidden menu for this:

Settings → About TV → Press 5 times on "Version MIUI TV" → Service menu → LED Zones

⚠️ Warning: Changing the settings in the service menu can cause a reset or an unstable TV!

Comparison of Xiaomi’s Adaptive Lighting with OLED and QLED

To understand whether to overpay for adaptive lighting, compare it with the main competing technologies: OLED and QLED (This is something that Samsung uses, for example).

The main advantage of adaptive lighting Xiaomi before OLED — No risk of burnout, which is critical if you're often watching logo channels or playing static games. HUD. On the other hand, OLED It provides the perfect black at pixel level, while even the best LED-TVs suffer from blooming.

Compared to QLED, Xiaomi's adaptive backlight loses in peak brightness but wins in price. TV Master Ultra with Mini LED It will be cheaper than Samsung. QN90C with similar characteristics. QLED It is better suited for brightly lit rooms due to anti-reflective coating.

Adaptive lighting for games: whether to include on Xiaomi TV

If you use a Xiaomi TV for gaming (on PlayStation 5, Xbox Series X or PC), adaptive lighting can help or hurt.

• ⚡ Input Lag: Turning on local dimming adds 10-20 ms of latency. For single-player games, this is not critical, but in shooters (for example, Call of Duty) can be noticeable.
• 🎮 HDR Contrast: In games with support HDR (Like God of War. Ragnarök) Adaptive lighting improves perception, especially in darker locations.
• 🔄 Artifacts in dynamic scenes: In fast games (racing, fighting games) can manifest "shimmering" of the lighting zones, which distracts.

Recommendations for gamers:

1. For competitive games (CS2, Valorant) – disable local dimming and set the Game mode in picture settings.
2. For single-player projects (The Last of Us, Cyberpunk 2077) – Enable Medium Local Dimming Mode and activate Dolby Vision.
3. For retro games (emulators) SNES, PS1) — Turn off all post-processing, including adaptive backlighting, to avoid lags.

Important: Xiaomi TVs with support HDMI 2.1 (e.g. Master Series) can be enabled ALLM (Auto Low Latency Mode, which automatically optimizes latency when connecting the game console, however, even in this case, local dimming will add a small lag.

💡

For maximum performance in games, low input lag is a priority, not depth black. If you're serious about esports, consider a monitor with a high-resolution esports screen. TN-A matrix instead of a TV with adaptive lighting.

Frequent problems with adaptive lighting and how to solve them
