Xiaomi Mi TV 4S 43 remains one of the most popular budget smart TVs on the market due to the combination of price, functionality and picture quality. However, when choosing this model, many users are faced with the main question: which matrix is inside – VA (high contrast) or IPS (wide viewing angles)?
The fact is that Xiaomi does not always specify the type of matrix in the official specifications, and different batches of TVs can be equipped with panels from different manufacturers. TV 4S 43 (model L43M6-6ARU, L43M6-6ASR And others, but we also teach you how to define the type of panel without disassembling the device, and you also learn how the type of matrix affects the quality of the panel. HDR, game mode and power consumption.
Official data: what matrix installed in Xiaomi Mi TV 4S 43
According to Xiaomi documentation and analysis of serial numbers, two types of matrices were installed in the Mi TV 4S 43 (2019-2022).
- 🔹 VA-matrix BOE (model BV043FUM-N**) — The most common option is that these panels are black in depth (contrast up to 4000:1) and bright, but they suffer from fading when viewed from an angle.
- 🔹 IPS-matrix LG Display or Innolux (less commonly) – found in early batches or regional modifications, their advantages: stable color reproduction in side view and less input delay (relevant to gamers), but the contrast is lower (1000:1).
It is important to remember that the same model of the TV (for example, the same model of the TV, L43M6-6ARU) It could be equipped with different matrices depending on the batch. 2021 Xiaomi has started to use more actively VA-panels because of their cheapness, so chances are IPS-The version in new devices is minimal.
⚠️ Note: In Chinese versions of the Mi TV 4S 43 (for example, L43M6-6ASR) almost VA-Matrix: European and Russian modifications (L43M6-6ARU) could have been both.

2. How to determine the type of matrix in Xiaomi Mi TV 4S 43: 4 working methods
If you’ve already bought a TV or are considering a specific instance in a store, here are ways to check the type of matrix without disassembling:
Method 1. Visual test for viewing angles
- 📺 Turn on a black screen on your TV (for example, through a YouTube video with test pictures).
- 👀 Step aside at 45-60.° If the black color turns gray, it's the center of the screen. VA. If it stays black — IPS.
- 🔴 Check the red color: VA-The matrix will be "rose" in the side view, on IPS — saturate.
Method 2. Service menu (for advanced users only)
Go to the engineering menu of the TV:
Press sequentially on the remote:
Menu → Settings (⚙️) → All settings → Device → About Device → Press 5 times on "Television Model"In the menu that opens, look for Panel Info or Display.
- Panel Type: VA or MVA;
- Panel Type: IPS or AH-IPS.
⚠️ Warning: Do not change the settings in the service menu – this can cause the TV to reset or damage the firmware!
Method 3. Based on matrix model number
On the back of the TV, look for a sticker with the serial number, and the Panel Model or Display bar can indicate:
- 🔹 BV043FUM-N** — VA from BOE;
- 🔹 LTD043 or VSN043 — IPS from LG Display;
- 🔹 M230H1-L** — IPS Innolux (rarely found).
Method 4. via applications (Android TV)
Install TV Panel Info or Display Tester from Google Play, which analyzes the screen and shows the type of matrix.
- 📊 Contrast Ratio: above 2000:1 — VA, below 1200:1 — IPS;
- 🎯 Response Time: Less than 8ms, most likely IPS.
💡
If the service menu or label contains a code BV043FUM-N41 Or similarly, that's 100% VA-matrix BOE, most common in Mi TV 4S 43.
VA vs IPS in Xiaomi Mi TV 4S 43: comparison by key parameters
To understand which matrix is best for your tasks, compare them by the main criteria in the table format:
| Parameter | VA-matrix | IPS-matrix |
|---|---|---|
| Contrast | 3000:1–4000:1 | 800:1–1200:1 |
| Viewing angles | Decrease in brightness/color at ≥30° | Stable image up to ≈70° |
| Delayed input (Input Lag) | 12-15 ms (in game mode) | 8-10 ms. |
| Color rendering (sRGB) | ≈90% (may be overpriced out of the box) | ≈95% (more natural) |
| HDR (Dolby Vision) | Better displays shadows and lighting | Less noticeable effect due to low contrast |
The table shows that the VA-matrix wins in movies and TV shows due to its deep black color and good HDR, and the IPS is better suited for playing and watching with a large company (because of the wide angles), but the VA has a serious disadvantage - a "dirty" screen (Dirty Screen Effect, DSE) when watching light scenes when there are divorces on homogeneous surfaces (for example, in football or hockey).

How the type of matrix affects the performance of the TV: real tests
We tested the Xiaomi Mi. TV 4S 43. VA- and IPS-And this is what happened:
Test 1.Cinema in 4K HDR
- 🎬 VA: Black scenes (such as Blade Runner 2049) look deep, details are preserved in the shadows, but when bright light in the room, the contrast is blurred".
- 🎬 IPS: It's flatter, but it's more natural. IPS looks better VA.
Test 2 Games (PS5/Xbox Series X)
- 🎮 VA: In dynamic scenes (such as Call of Duty), you can see a delay in input. DSE entangles in bright locations.
- 🎮 IPS: The response is faster, but low contrast makes it harder to see the enemy in the dark corners of the map.
Test 3: Energy consumption
At the same brightness (200 cd / m2):
- ⚡ VA Consumes 10-15% less energy due to better lighting control.
- ⚡ IPS It costs more due to uniform lighting throughout the area.
Test 4. Durability
VA-matrixes over time can lose brightness due to the degradation of backlight, especially with frequent on/off. IPS in this regard is more stable, but afraid of mechanical pressures (the risk of “broken pixels”).

5.Can you replace the matrix in Xiaomi Mi TV 4S 43?
It's technically possible to replace the matrix, but economically it's almost always impractical.
- 💰 Cost of a new matrix (e.g, BV043FUM-N41) — 15 000–20 000 ₽, That’s the same as the price of a new TV.
- 🔧 Replacement work costs 5,000–8,000 ₽ (It requires a complete disassembly, rationing of plumes).
- ⚠️ Risk of damage to control board or backlight during dismantling.
The exception is if you have broken pixels or physical damage to the screen, and the TV is still warranty, in which case Xiaomi can replace the matrix for free (provided that the defect is not the fault of the user).
⚠️ Warning: If you replace the matrix yourself, you lose your warranty! In addition, new panels often go unlit, and its transfer from the old matrix requires special equipment.
If you are not satisfied with the type of matrix in your Mi TV 4S 43, it is more logical to sell the device and buy a model with the desired panel (for example, Xiaomi TV A2 43 with IPS or Redmi Smart Fire TV with VA).
