How many candelas in the Xiaomi TV: analysis of all series (2020-2026) and how it affects the image quality

When you choose a Xiaomi TV, one of the key parameters is screen brightness, measured in candela per square meter (cd/m2), which determines how comfortable it is to watch movies during the day in bright light or at night in complete darkness. However, manufacturers rarely specify the exact values of candela in the characteristics, and if they do, often overstate or cite data for ideal laboratory conditions.

In this article, we will analyze the real brightness indicators for all popular Xiaomi TV series (including Mi TV A Pro, Redmi Smart TV, Premium QLED and others), explain how candela affect the perception of a picture, and teach you to measure brightness yourself using a smartphone or specialized devices.

What are candela in TV and why is it important?

Candela (cd/m2) is a unit of measure of the brightness of the light that a screen emits, and the higher this indicator, the better the TV copes with ambient lighting.

  • πŸŒ‘ 100-200 cd/m2 is enough for a dark room, but during the day the picture will be faded.
  • β˜€οΈ 300-500 cd/m2 – optimal for most living quarters with windows.
  • πŸ”† 600+ cd/m2 – suitable for very bright rooms or commercial use (e.g. in shop windows).

Manufacturers often indicate peak brightness (the maximum value when playing bright scenes), but in reality the TV rarely works on such indicators constantly. For example, the Xiaomi Mi TV Q2 75" in the characteristics has the declared 450 cd / m2, but when tested in HDR mode, the brightness drops to 380-400 cd / m2 due to power consumption restrictions.

⚠️ Warning: Don't confuse brightness (candela) with contrast. Even a TV with 1000 cd/m2 will look dull if it has a low contrast ratio (for example, cheap ones). IPS-panels).

It is also worth considering that Xiaomi uses different types of matrices:

  • πŸ“Ί VA-panels (in most models) – high contrast, but smaller viewing angles.
  • 🌈 QLED (in premium series) - brightness up to 1000 cd / m2, but more expensive.
  • πŸ’‘ OLED (rarely, for example, Mi TV Master OLED) β€” Self-emitting pixels, perfect black, but risk of burnout.

The actual brightness is always lower than the declared 10-20% due to the limitations on power consumption and heating of the matrix.

How to measure candela on your Xiaomi TV

If you want to know the exact brightness of your TV, there are a few ways to do this:

Method 1: Using a smartphone (approximately)

Use luxemeter applications like Lux Light Meter (Android) or Light Meter (iOS).

  1. Open a white screen on the TV (you can use a YouTube video with a test signal).
  2. Attach the smartphone screen to the TV (light sensor should be directed to the center).
  3. Write down the numbers in lux (lx).
  4. Transfer the suites to candela according to the formula: cd / m2 β‰ˆ LC / Ο€ (for example, 300 LC β‰ˆ 95 cd / m2).

⚠️ This method gives an error of up to 30%, as the sensors of smartphones are not calibrated for accurate measurements.

Method 2: With the help of specialized devices

For accurate measurements, use:

  • πŸ“ Colorimeter (e.g. X-Rite) i1Display Pro – measures brightness, color temperature and contrast.
  • πŸ”¦ Luxmeter (e.g, UNI-T UT383) β€” budgetary option, but requires manual recalculation.

Professional tests are conducted in a dark room with calibrated equipment, for example, for Xiaomi Mi TV P1, measurements show:

  • Brightness in Standard mode: 290 cd / m2.
  • Brightness in Movie mode: 220 cd / m2 (lowered for better black transmission).
  • Peak brightness in HDR: 410 cd/m2 (per 10% of the screen area).

Why Xiaomi TV is dull: 5 reasons and solutions

If your Xiaomi TV seems too dim, even if it has high brightness, check out the following points:

  1. Eco-mode or light sensor In settings, you can turn on energy saving mode or automatic brightness control. Turn it off along the way: Settings β†’ Display and sound β†’ Brightness β†’ Auto-brightness (off).
  2. Movie or Energy Saving modes artificially lower the brightness. Switch to Standard or Vivid.
  3. Some versions of Xiaomi software had a brightness limiting bug. Update the TV through Settings β†’ About TV β†’ System Update.
  4. Problems with illumination B VA-And when the lights go down, the lights go down, and the lights go down, that's a reason for the service center.
  5. Even at 500 cd/m2, direct sunlight can clog the picture. Use curtains or anti-reflective coatings.

⚠️ Note: If after resetting settings (Settings) β†’ Preferences β†’ Reset brightness has not recovered, the problem may be in the hardware (for example, a malfunction of the backlight driver.

πŸ’‘

To check the uniformity of the backlight, open a gray screen (50% brightness) in complete darkness on the TV, and dark spots at the corners or edges indicate a matrix defect.

Xiaomi Comparison with Competitors: Who is Brighter?

For objectivity, compare the brightness of Xiaomi TVs with models of other brands in the same price segment (data for 2026):

Brand and modelType of matrixBrightness (SDR), cd/m2Brightness (HDR), cd/m2Price (from)
Xiaomi Premium QLED 65"QLED45080080 000 β‚½
Samsung Q60C 65"QLED35060090 000 β‚½
LG QNED80 65"QNED (Mini LED)400700100 000 β‚½
TCL C745 65"QLED38050070 000 β‚½

As you can see from the table, Xiaomi in the premium segment (Premium QLED) is not inferior to Samsung and LG in brightness, but loses in HDR processing (competitors have better local dimming). In the budget segment (Redmi Smart TV), brightness is below the market average, but the price is appropriate.

If you’re looking for brightness, look for Direct LED or Mini LED models that give you a more uniform and bright glow. For example, the Xiaomi Mi TV Q2 75 uses direct lighting with 96 dimming zones, which improves contrast and peak brightness.

Why is QLED brighter than a regular LED?
QLED-TVs (e.g. Xiaomi Premium) QLED) They use quantum dots that enhance the brightness and saturation of color. LED-panels where light passes through color filters (losing up to 70% of brightness), QLED It converts blue LED light into red and green light without significant loss, so at the same lighting power, it's a very powerful light. QLED It will be 30-50% brighter.

How to increase the brightness of the Xiaomi TV: hidden settings

If the standard settings do not give enough brightness, you can use hidden modes or calibration through the service menu. ⚠️ Warning: Mistakes can lead to TV reset!

Method 1: Service menu (for experienced users)

To open the service menu on most Xiaomi models, follow the following steps:

  1. Turn off the TV remote.
  2. Press the remote sequentially: Menu β†’ 1 β†’ 3 β†’ 9 β†’ Menu (for some models – Menu β†’ 1 β†’ 1 β†’ 4 β†’ 7).
  3. In the menu, look for Backlight or Brightness Control.
  4. Increase the value by 10-15% from the current one (do not put a maximum, so as not to reduce the life of the matrix!).
  5. Save the settings and restart the TV.

Method 2: Calibration by ADB

For advanced users, you can change the brightness parameters through ADB (Android Debug Bridge).

  • πŸ–₯️ Computer installed ADB.
  • πŸ”Œ Included debugging by USB on the TV (Settings) β†’ On TV. β†’ POS version β†’ 7 times press).

A command to increase brightness (e.g. up to 80%):

adb shell settings put system screen_brightness 204

Where 204 is the brightness value in the range of 0-255 (80% of the maximum).

⚠️ Note: Change settings through the service menu or ADB If you are not sure of your actions, contact the service center.

After manually adjusting the brightness, check the TV for broken pixels. A sharp increase in backlight can reveal hidden matrix defects.

FAQ: Frequent questions about the brightness of Xiaomi TVs

πŸ” Why the specifications are 400 cd/m2, but in practice the screen is dull?
Manufacturers indicate peak brightness (maximum when playing bright scenes), whereas in normal mode (SDR) It's 20 to 30 percent lower in brightness, and it's also affected by real visibility: 🌞 External lighting (even 500 cd/m2 may appear dim in direct sunlight). 🎨 Image mode (in Movie, the brightness is lowered for better shadow detailing). πŸ”‹ Energy saving settings (e.g. Eco mode).
πŸ“Ί What is the minimum brightness required for comfortable viewing during the day?
Depends on the lighting of the room: 🏠 Living room with windows - from 300 cd / mΒ². 🌳 A room with scattered light - 250-300 cd / mΒ². β˜€οΈ Direct sunlight - 500+ cd/m2 (or anti-reflective coating). Xiaomi will suit the Mi models TV Q2 (400 cd/m2 or Premium QLED (500+ cdΒ²).
⚑ Can I increase the brightness above the factory settings?
Yes, but with reservations: βœ… Service menu (see section above) – 10-15% increase is safe. ❌ Through modified software - the risk of overheating the matrix. ⚠️ ADB-commands are working, but may reset after the upgrade. You should first check if the power saving mode is on (Settings) β†’ Energy conservation).
πŸ’‘ Why? OLED-Xiaomi TVs are dimmer LED into SDR-mode?
It's a feature. OLED-technology: πŸ”‹ Energy saving: pixels emit light on their own, and high brightness reduces their resource. πŸ–ΌοΈ ABL (Automatic Brightness Limiter: When there is a lot of white on the screen, the brightness automatically decreases to prevent overheating. 🎬 Optimization for HDR: darkly OLED It shows better detail than LED. In Mi TV Master OLED brightness SDR limited to 150–200 cd/m2, but in HDR It can reach 600-800 cd/m2 in small areas.
πŸ› οΈ What to do if the brightness dropped after updating the firmware?
Probable causes and solutions: Settings reset: Update your firmware to the latest version, then reset (Settings β†’ Preferences β†’ Reset). Software bug: check feedback on forums (e.g. 4PDA or Mi Community). If the problem is massive, wait for a patch. Power restriction: new firmware can activate hidden power saving mode. Try to roll back to the previous version (if available). If nothing helps, contact Xiaomi with TV logs (Settings β†’ About TV β†’ Diagnostics).
