20 Band in Xiaomi TVs: Technology, Benefits and How It Works in Practice

If you're looking at the characteristics of today's Xiaomi TVs -- like the Mi TV Q2, A Pro or P1 -- you've probably heard the cryptic term "20 Band," which the manufacturer is heavily putting a spotlight on in advertising, but what's really behind this technology? Why are 20 stripes better than 16 or 12, and how does that affect the image you see on the screen?

In this article, we’ll take a technical look at the 20 Band: how it works with 20-zone dimming, how it differs from traditional solutions, and whether it’s really so important for HDR quality. Also, you’ll learn which Xiaomi models use this technology, how to test it when you buy it, and whether you should overpay for a TV with 20 Band instead of more budget options.

What is the 20 Band in Xiaomi TVs: just about the complex

The term 20 Band (or 20-zone backlight) refers to the number of independent backlight segments in a TV array. Unlike cheap models where backlights evenly illuminate the entire screen (called edge-lit or direct-lit with a minimum number of zones), in 20-band TVs, the screen is divided into 20 separate blocks, each unit can adjust the brightness independently of the others, which allows:

• 🎯 It is more accurate to convey contrast – dark scenes become really dark, and bright – saturated.
• 🌈 Improve quality HDR-content where detail in shadows and lights is important.
• 👁️‍🗨️ Reduce the effect of “lighting” (blooming) around bright objects on a dark background.

For comparison: budget TVs often use 8-12 backlight zones, and in premium models of other brands (for example, Sony X90K or LG QNED), this number can reach 100 or more. Xiaomi with 20 Band occupies an intermediate position - this is not the top level, but a significant step forward compared to the basic models.

It's important to understand that the 20 Band is not the same as local dimming, which involves dynamically controlling the brightness of zones in real time, and the 20 Band is just the number of those zones, but in Xiaomi TVs, these technologies usually work together.

How 20 Band Affects Image Quality: Comparisons with 12 and 16 Zones

To understand how noticeable the difference between the 20 Band and the more modest variants (for example, the 12 Band or the 16 Band) is, let’s look at specific scenarios:

In practice, the difference between the 16 Band and the 20 Band becomes noticeable when watching high dynamic range movies (HDR10, Dolby Vision). For example, in scenes with night city or space scenes, a TV with 20 zones will work better between light and shadow, without pouring gray images. However, in everyday use (watching TV, YouTube, games), the difference may not be so obvious.

⚠️ Note: Not all Xiaomi models with 20 Band are equally good at implementing this technology. TV Q2 55" lighting area is larger than the Mi TV A Pro 65" so the effect can be different even within the same line.

What Xiaomi models use the 20 Band: full list of 2023-2026

The 20 Band technology has been introduced in Xiaomi TVs since 2022, and is currently available in the following models (2026):

• 📺 Xiaomi Mi TV Q2 (all diagonals: 55, 65, 75′′ – flagship series with quantum dots.
• 📺 Xiaomi Mi TV A Pro (55, 65, 75) – improved version of the A lineup with Dolby Vision support.
• 📺 Xiaomi Mi TV P1 (55, 65′′ – more budget option, but with 20 Band in the top versions.
• 📺 Xiaomi TV 6 OLED (55, 65) – 20 Band works differently here (see spoiler below).

Please note: in the models with OLED-matrix (e.g, TV 6 OLED) The term 20 Band may not mean backlight zones (there are no backlights, because each pixel glows independently), but brightness control zones to optimize power consumption and prevent burnout.

If you choose between models, pay attention not only to the number of backlight zones, but also to the type of matrix:

- VA-panels (used in most cases) LED-Xiaomi TVs are better at contrast but have smaller viewing angles.

OLED provides the perfect black color, but can suffer from burnout when static elements (e.g. channel logos).

How to check the work of 20 Band when buying: tests and settings

To make sure that the Xiaomi TV is actually using the 20 Band and that this feature works correctly, follow the following steps:

You can use YouTube test videos for more accurate checks (search for “HDR test 4K” or “local dimming test”).

• 🔍 In scenes with black backgrounds and bright objects (for example, stars in the night sky) there should be no strong illumination around objects.
• 🌓 In gradient transitions (from dark to light) there should be no sharp jumps in brightness - the transition should be smooth.
• 🎬 In dynamic scenes (such as explosions in movies), backlight zones should respond quickly to changes without delay.

If you buy a TV online, pay attention to user reviews — there are often problems with backlighting (for example, uneven glow at the edges of the screen), in Xiaomi Mi TV Q2 and A Pro models, such defects are less common than in the budget series.

💡

To check the uniformity of the backlight, use a gray test screen (can be found in the settings of the TV or through applications like Display Tester).Ideally, the screen should be uniform, without bright spots or darkened areas.

20 Band vs Full Array Local Dimming: What's the Difference?

The term Full Array Local Dimming is often used in 20 Band discussions (FALD). This is a more advanced technology, where the backlight zones are not only numerous, but also evenly distributed throughout the screen area (unlike edge-lit, where LEDs are located only at the edges). FALD, a) Intermediate option.

The main differences:

• 🔹 20 Band (Xiaomi): Larger backlight zones, less precise controls, but cheaper to produce.
• 🔹 FALD (Premium brands: hundreds of smaller areas, more accurate dimming, but also the price is much higher.

Xiaomi’s 20 Band TVs take a hybrid approach: LEDs are spread across the screen (like FALD), but their number and size are smaller than those of top Samsung or Sony models. This allows you to balance between price and quality, but does not reach the level of premium solutions.

If you’re critical of maximum HDR quality, consider FALD TVs (like the Sony X95K or TCL QM8). However, for most users, Xiaomi’s 20 Band will be more than enough of a compromise.

Should you pay more for 20 Bands: a comparison with alternatives

Xiaomi's 20 Band TVs are typically 15 to 30 percent more expensive than models with 12 to 16 backlight zones. Is that overpayment worth the money? It all depends on your tasks:

If you don't watch much HDR-If you don't play games with dark scenes (like Horizon Forbidden West or Cyberpunk 2077), it doesn't make sense to overpay for 20 Band, but for moviegoers and gamers, the difference will be noticeable, especially in high-contrast scenes.

⚠️ Note: Some Xiaomi models (e.g. Mi) TV P1) Local dimming is disabled by default. To take advantage of 20 Band, go to the image settings and activate Local Dimming or Dynamic Backlight.

Frequent 20 Band Problems and How to Fix Them

Despite the advantages, Xiaomi’s 20 Band technology sometimes doesn’t work perfectly on its TVs, and here are some of the most common problems and ways to fix them:

• 🔦 Blooming (glow around bright objects): Reduce the brightness of the backlight in the settings or turn on Movie mode instead of Dynamic.
• 🖥️ Screen flickering in dark scenes: Turn off Auto Brightness or update the TV firmware.
• 🎛️ Uneven lighting at the edges: This is a matrix defect - contact the service center if the TV is guaranteed.

If the backlight quality deteriorates after the firmware update, try resetting the image to factory settings (Settings → System → Resetting). In rare cases, a rollback to the previous version of the software helps (instructions are available on the 4PDA or Xiaomi Community forums).

💡

Before buying a 20 Band TV, be sure to check it for a "clouding" effect. This can only be done when it's off in a dark room -- turn on the flashlight and shine it at an angle. If you see dark or light spots, don't buy this model.
