If you own a Xiaomi Mi TV TV, Redmi Smart TV or models of the Xiaomi series TV A Pro, then probably encountered a mysterious acronym NR This option appears on the menu every now and then, but not everyone understands what it's for and how to use it, NR (Noise Reduction is one of the key video processing technologies that can both save a bad image and ruin a good one if configured incorrectly.
In this article, we will explain in detail what is NR Xiaomi TV, How it works at the hardware and software level, when it should be turned on and when it should be turned off, and how to fine-tune noise cancellation to different signal sources, from terrestrial TV to streaming services like Netflix or YouTube, and we'll also test how to do this. NR Input lag is critical for gamers connecting consoles to the TV.
Spoiler: If you watch movies in high resolution (4K HDR) from a good source, then the inclusion NR It can make the picture less detailed than it can improve, but for analog TV or compressed streams (e.g., for example, IP-TV In low bitrate, this function is absolutely necessary. Read on to understand all the nuances!
What is it? NR Xiaomi TV: decoding and working principle
NR Noise Reduction is a technology for reducing digital noise in an image. In Xiaomi TVs, it works at the processor level (for example, in models with MediaTek chips). MT9611 or amlogic T972) and can apply different algorithms depending on the source of the signal:
- ๐บ For on-air/cable TV โ suppresses โsnowโ and compression artifacts MPEG-2/MPEG-4.
- ๐ฎ For gaming consoles, it tries to smooth out the noise from low-quality HDMI-cables or weak signal.
- ๐ For streaming services โ reduces blocks (macroblocking) in streams with low bitrate.
- ๐ผ For analogue sources (VGA, AV) โ Removes interference and ripples from a bad connection.
Technology NR two-type:
- Spatial noise cancellation โ analyzes neighboring pixels in one frame and smooths out the differences between them, effectively against static noise (for example, โsnowโ in dark areas).
- Temporary noise cancellation โ compares several consecutive frames and removes artifacts that appear and disappear (for example, flickering or โjunkโ from compression).
Xiaomi TVs typically use a combined approach, but the force of exposure is manually adjusted. NR It doesn't increase the actual resolution, it just masks the defects, making the picture visually cleaner, and too aggressive settings can blur fine details (such as text or characters' hair).
Where is the setting NR Xiaomi menu TV
Depending on the TV model and firmware version MIUI TV, path NR Here are the current options for most devices (2020-2026 release years):
| Model TV set | The way NR | Additional options |
|---|---|---|
| Xiaomi Mi TV 4S/4A/4C | Settings โ Image: โ Additionally. โ Noise suppression (NR) | Force adjustment (0โ100), separately SD/HD/4K |
| Redmi Smart TV X | Settings โ Picture โ Advanced settings โ Noise Reduction | Automatic, manual setting for each entrance |
| Xiaomi TV A Pro 2023 | Settings โ Display and sound โ Image quality โ NR | AI-Optimization, separately for movies/sports/games |
| Xiaomi TV Q2/Q1E | Settings โ Image: โ Intelligent settings โ Noise suppression | Adaptive mode, binding to sources |
If you don't find an option NR on the menu, check it out:
- ๐ The firmware version - in the old versions MIUI TV (below 3.0) the function could be called "Noise Reduction" or hidden in the engineering menu.
- ๐บ Current signal source โ some models show settings NR only for active entry (HDMI1, HDMI2, TV etc.).
- ๐ Image mode โ in the Game or Sport modes, the option can be blocked.
Xiaomiโs new TVs (2023โ2026) are common AI NR โ It's an improved version with machine learning that automatically adapts to the content. It can be identified by the icon. ๐ค slider-side.
๐ก
If there is no explicit item in your model "NR", Try to turn on Movie Mode โ it often activates noise cancellation automatically for movies.
When to turn on NR and when to turn off: practical recommendations
There is no universal answer to the question โwhether to includeโ NR". It depends on the source of the signal, the resolution of the content, even the lighting in the room:
Turn on NR maximum (80-100) for on-air TV (DVB-T2) jammed|Shut down. NR for 4K HDR-content (Netflix, Blu-ray)|Install NR 30 to 50 for YouTube 1080p low-bitrate|Turn it off. NR game console (PS5, Xbox Series X)|Use it. AI NR for sports broadcasts (reduces artifacts when moving fast)-->
Let's take a closer look.
โ When NR useful:
- ๐ก Etheric or cable TV, especially in low signal areas. NR It will help to remove snow and ripples.
- ๐ถ IP-TV Low bitrate โ reduces blocks (macroblocking) in compressed video.
- ๐๏ธ Older movies or low quality videos โ smooths out the graininess of the film.
- ๐ Dark scenes โ removes colored noise in shadows (for example, in horror films).
โ When NR harmful:
- ๐ฎ Game consoles โ adds latency (input lag) and blurs textures.
- ๐บ 4K HDR-Content โ can โeatโ details in high-quality video.
- ๐ฅ๏ธ PC as a monitor - blurs text and interface.
- ๐ธ High-resolution photo or video artificially smoothes out real details.
Simple test: turn on NR 50 percent and look at the little things, like the actor's hair or the grass on the football field, and if they're less clear, you can either reduce the value or turn it off completely.

How to set up correctly NR Xiaomi TV: step-by-step
Setting up NR โ It's not just on and off. To get the best results, follow this algorithm:
- Select the source of the signal you will be setting up for NR (for example, HDMI1 for consoles or built-in tuner for terrestrial TV).
- Run test content โ a scene with lots of dark areas and small details (for example, a night shot of the city) is best suited.
- Open the settings. NR the path corresponding to your model (see table above).
- Start with a minimum value (10-20) and gradually increase as you watch for changes.
- Evaluate the result: โ๏ธ Noise is reduced, details are saved - leave the current value. โ The picture blurred, lost clarity - reduce NR or offline.
Save profile.
For models with AI NR (for example, Xiaomi TV A Pro 2023: The algorithm is simplified:
- Turn it on. AI Noise Reduction.
- Choose the type of content: Film, Sports or Game.
- Give the TV 10-15 seconds to analyze it โ it will automatically select the optimal parameters.
If after setting up the picture still does not suit, try resetting the image settings to factory (Settings) โ Image: โ Reset) and start again.

On Xiaomi TVs with MediaTek processor MT9611 (Like Mi. TV Q1 75โฒโฒ noise reduction works better when you simultaneously enable the option Super Resolution (superresolution).
NR Other Image Processing Functions: How They Interact
NR โ It's not the only technology that affects the final image. It works with Xiaomi TVs:
- ๐ Super Resolution โ Increases the resolution of low-quality content (e.g., with a high-resolution content content content) 720p before 1080p).
- ๐ HDR Remaster โ Improves color range and contrast.
- ๐ญ Motion Clarity โ reduces blur during fast movement (analogue of the soap effect).
- ๐ผ๏ธ Dynamic Contrast โ automatically adjusts the brightness of dark and light areas.
The problem is that these functions can conflict with each other, like:
- NR + Super Resolution โ It can create a "plastic" effect on the face.
- NR + Motion Clarity โ Adds artifacts in dynamic scenes (sports, action movies).
- NR + Dynamic Contrast โ darkened areas too much, "eating" parts.
Recommendations for combination:
| Purpose | NR | Super Resolution | Motion Clarity | Dynamic Contrast |
|---|---|---|---|---|
| Movies (dark scenes) | 30โ50 | Off. | Off. | 20โ40 |
| Sport (football, hockey) | 20โ30 | Off. | 50โ70 | Off. |
| Games (consoles) | Off. | Off. | Off. | Off. |
| Etheric TV (weak signal) | 70โ100 | 30โ50 | Off. | Off. |
If you are not sure which settings to choose, use the preset modes:
- Movies โ Optimized for Movies (NR ~30, Dynamic Contrast ~40).
- Sport โ Increased clarity of movement (NR ~20, Motion Clarity ~60).
- The game is minimal processing (all options are turned off).

Common problems with NR And how to solve them.
Even after the right setup NR These are the most common user complaints and how to address them:
๐ด Problem: The picture became "soapy" or blurred
Reason: Too high a value NR (Especially when paired with Super Resolution).
Decision:
- Reduce. NR until 20 to 30.
- Turn off Super Resolution.
- Check if Movie Mode is on โ it can automatically overstate noise cancellation.
๐ด Problem: Artifacts in the form of "squares" or stripes
Cause: Conflict NR video compression (especially in the IP-TV YouTube).
Decision:
- Turn it off. NR - I'll have you check the entire system and see if there's any artifacts left.
- If you use IP-TV Prefix, try to reduce the bitrate in its settings.
- For YouTube, select a higher resolution (e.g, 1440p instead 1080p).
๐ด Problem: Delay in games (input lag)
Reason: NR adds staff buffering for processing.
Decision:
- Turn it off. NR fully-play.
- Activate Game Mode in the settings of the TV.
- If you play through GeForce NOW Xbox Cloud Gaming, reduce the resolution of the stream โ this will reduce the load on the TV processor.
๐ด Problem: NR not working or a gray slider
Reason:
- Current signal source does not support setting NR (for example, AV-entry).
- The game mode is on or PC, where NR shutdown.
- Outdated firmware (update TV via Settings โ Software Update).
How to reset the image settings if NR misbehave?
If none of the tips helped, there may be a hardware problem (e.g., a malfunctioning video processing processor) in which case, contact Xiaomi's service center.
Comparison NR Xiaomi TV Competitors: Who is better at handling noise?
All the major television manufacturers have noise reduction technologies, but they're implemented differently. NR Xiaomi with Samsung analogues, LG Sony:
| Brand | Name of technology | Advantages | Deficiencies | Better than Xiaomi? |
|---|---|---|---|---|
| Samsung | Auto Motion Plus / Digital Clean View | It works well with SD-content, few artifacts | He's very blurry in detail. 4K, costly | Yes. SD) |
| LG | TruMotion / Noise Reduction | Minimum input lag, good for gaming | Weak noise cancellation in dark scenes | No (for movies) |
| Sony | X-Reality PRO / 4K XR | Best quality of scaling, natural picture | High price, complex settings | Yes (for 4K) |
| Xiaomi | Noise Reduction / AI NR | Flexible settings, inexpensive models, good balance | Sometimes blurring details, weak support HDR | โ |
Xiaomiโs main advantage is its price/quality ratio. TV A Pro 55" with" AI NR It costs 2-3 times less than Sony or Samsung flagships, but offers comparable noise reduction capabilities. A95K Samsung QN90C) More advanced algorithms are used that better retain details when removing noise.
If you want the best quality and you're willing to pay for it, Sony or Samsung is the best choice. NR โ fine.
