Why is the processor important for a smart TV?
The choice of Xiaomi Mi TV 4S 55 is often accompanied by questions about its “stuffing” — especially the processor that determines the speed of the interface, the quality of video processing and even power consumption. Unlike smartphones, where chipsets are updated annually, TVs can use the same processor in several generations of models, which makes its analysis even more important: the right choice depends on how comfortable you will be using the device in 3-5 years.
In this article, we will analyze in detail what processor is installed in Xiaomi Mi. TV 4S 55 inches, compared to competitors (including Samsung models, LG and TCL), And we'll also give you practical tips for how to optimize it, and we'll focus on the hidden capabilities of the Amlogic chipset. T962, which the manufacturer does not advertise, but which can be activated through the engineering menu.
Technical characteristics of the Xiaomi Mi TV 4S 55 processor
The Xiaomi Mi TV 4S 55 is based on the Amlogic T962 chipset, a 64-bit processor based on the ARM Cortex-A53 architecture released in 2018, which is a low-end chip, but thanks to optimization by Xiaomi, it demonstrates performance comparable to more expensive counterparts.
- 🔹 Cores: 4 × Cortex-A53 clock speed up to 1.5 GHz (in turbo mode - up to 1.8 GHz).
- 🎮 Graphics: Mali-450 MP3 (3 cores) with OpenGL support ES 3.2 and Vulkan 1.0.
- 📺 Video decoding: hardware support 4K HDR (including H.265/HEVC, VP9, H.264).
- 🖥️ Memory: 2 GB DDR4 (In some regions, 1.5 GB DDR3, see the table below).
Importantly, the Amlogic T962 is a modification of the older Amlogic S905X chipset, adapted specifically for TVs, with improved HDMI 2.1 support (though not in full specification) and optimization for Android TV 9.0, which is installed in the Mi TV 4S 55 out of the box.
Comparison with competitors: who is stronger?
To see how good the Amlogic T962 is, compare it to the chipsets that other manufacturers use in similarly priced TVs (55 inches, budget-medium).
| Model TV set | Processor | Core/Frequency | Graphics | Support for 4K HDR |
|---|---|---|---|---|
| Xiaomi Mi TV 4S 55 | Amlogic T962 | 4×1.5–1.8 GHz | Mali-450 MP3 | Yes (HEVC, VP9) |
| TCL 55P615 | MediaTek MT5658 | 4 × 1.3 GHz | Mali-470 MP3 | Yes (with limitations) |
| Samsung Crystal UHD TU7000 | Samsung Exynos 7902 | 2 × 1.7 GHz | Mali-G31 MP2 | Yes (proprietary codec) |
| LG 55UK6200 | Realtek RTD2893 | 4 × 1.1 GHz | — | Partially (no VP9) |
The table shows that the Amlogic T962 beats competitors in clock speed and support for modern codecs, but loses Samsung Exynos in terms of energy efficiency (due to the outdated architecture of 28 nm vs. 14 nm in Exynos). However, for most users, the difference will only be noticeable when using intensively – for example, when running multiple applications simultaneously or streaming in 4K@60fps.
⚠️ Note: In some regions (e.g. India) Xiaomi Mi TV 4S 55 comes with a stripped-down version of the processor – Amlogic T962E, where core frequency is limited to 1.2 GHz, this can lead to slowdowns when working with heavy applications (for example, Netflix in the Internet). 4K). Check the marking on the box or in the settings (Settings) → On TV. → Processor model).
Real performance: tests and benchmarks
On paper, the Amlogic T962 specs look good, but how does it perform in real-world conditions?We tested the Xiaomi Mi TV 4S 55 in several scenarios:
- 📊 AnTuTu (Android TV): ~35,000 points (compared to Samsung) TU7000 pick up ~28 000).
- 🎬 Video playback: 4K HDR (HEVC) — No problem, but with high bitrate (>50 Mbps) artifacts possible. YouTube in 4K@60fps — It works stably, but when fastening back sometimes "hangs" on 1-2 seconds.
- 🎮 Games: Simple casual games (Asphalt 9, PUBG Mobile at minimum settings) go smoothly, but Genshin Impact or Call of Duty Mobile launches with a strong lag.
The main problem with the Amlogic T962 is overheating. With prolonged load (for example, 2+ hours of streaming in 4K), the temperature of the chip can reach 85-90 ° C, which leads to trottling (automatic frequency reduction), in which cases the interface begins to “brake”, and the video can hang down. The solution is to ensure good ventilation (don’t put the TV in a closed niche!) or use an external cooler.
💡
If the TV is too hot, try turning off the Auto Brightness feature in the settings (Settings → Screen → Brightness) which causes the CPU to constantly analyze the lighting in the room, which increases the load.
The hidden capabilities of the processor: what can be improved?
Manufacturer does not disclose all of Amlogic's features T962, But you can activate additional options through an engineering menu or a third-party firmware. TV 4S 55:
- Overclocking of the processor: Through ADB You can increase the frequency of the nuclei to 2.0 GHz (but it shortens the life of the chip!).Command: adb shell setprop sys.cpu.max_freq 2000000 ⚠️ Warning: Overclocking will void warranty and may cause overheating. Use only with active cooling (e.g., use only with active cooling, USB-cooler).
- Dolby Vision Activation: The chipset supports Dolby Vision, but Xiaomi has disabled this feature software, so you need to flash modified software to enable it (spoiler instructions).
- Increase video buffer: The default streaming buffer is 30 seconds. With build.prop, you can zoom in to 60 seconds, which will reduce the number of downloads when the Internet is slow.
How to flash Dolby Vision on Xiaomi Mi TV 4S 55
Another useful trick is to turn off unnecessary services that are loading the processor, such as the Xiaomi Mi Home Integration feature, which is constantly running in the background, even if you are not using it. ADB:
adb shell pm disable com.xiaomi.smarthomeFrequent Processor Problems and Solutions
Xiaomi Mi TV 4S 55 users often face typical problems associated with the Amlogic T962, and here are the most common ways to fix them:
- 🐢 Interface brake: Reason: Lack of RAM (especially if many applications are installed).Solution: Clear the cache through Settings → Annexes → Clear the cache or disable the autoload of unnecessary programs.
- 🔄 TV spontaneously reboots: Cause: CPU overheating or firmware failure Solution: Check the temperature (can be accessed via app) CPU Monitor from Google Play and update the software.
- 📶 Not reproduced. 4K Video: Reason: Outdated codecs or limitations HDCP. Solution: Update your firmware or use an external player (e.g., Kodi with support) HEVC).
☑️ What to do if the TV is slowing down
If problems persist, perhaps the fault is not the processor, and the memory eMMC, which in budget models Xiaomi often has a low read/write speed, in which case will only help to replace the memory module (which is not economically feasible) or use the TV in “light” mode (without installing third-party applications).
Should you buy Xiaomi Mi TV 4S 55 in 2026?
At the time of its release (2019), the Xiaomi Mi TV 4S 55 was one of the best deals in its price segment, but today its Amlogic T962 processor is obsolete.
| Pluses | Cons |
|---|---|
| ✅ Low price (in) 2–3 less expensive than new models with 4K@120Hz). | ❌ No support. HDMI 2.1 (maximum) HDMI 2.0b). |
| ✅ Good optimization for Android TV and Google Assistant. | ❌ Weak schedules (Mali-450) modern-game. |
| ✅ It is easily accelerated and modified (large community on the 4pda). | ❌ Overheating under prolonged loads. |
The conclusion: Xiaomi Mi TV 4S 55 is suitable if you want a low-cost TV for movies, TV series and light games. For gamers or those who plan to use a TV with PS5/Xbox Series X, it is better to consider models with HDMI 2.1 and MediaTek MT9611 or Realtek RTD1319 processors.
💡
Unless you’re planning to play heavy games or connect to a new generation of gaming consoles, the Amlogic T962 in the Mi TV 4S 55 will last another 3-5 years without any problems.
