How to set up a Xiaomi Mi TV 4S 43 inches: a complete guide from connectivity to fine-tuning

Xiaomi Mi TV 4S 43 is a popular model with a diagonal of 43 inches, combining affordable price and the wide capabilities of Smart TV. However, after buying, many users are faced with the question: how to adjust it correctly to get maximum image quality, stable sound and ease of control? Unlike more expensive brands, Xiaomi does not always offer an intuitive interface, especially for beginners.

In this article, we'll look at all the steps of the setup, from the first connection to the hidden features that the manufacturer doesn't advertise, how to optimize the image for different signal sources, adjust the sound for the home theater, connect the peripherals and avoid typical errors, and also the unique features of the Mi TV 4S 43, which are not written in the official instructions.

If you’ve just unpacked your TV, start with a basic setup. If the Xiaomi Mi TV 4S 43 is already working, but you want to improve its performance, go straight to the right section. All instructions are current for firmware 2023-2026 and have been tested in practice.

1. First connection and start of the TV

Before you turn on the Xiaomi Mi TV 4S 43, make sure that all cables are connected correctly. Only the remote and documentation are included - you will have to buy the power cable and HDMI separately if they are not available. Use original accessories or certified analogues to avoid voltage problems.

Connect the TV to the outlet and press the power button on the remote (or on the back of the TV). The Mi TV logo will appear on the screen, after which the initial setting will begin. The system will suggest you choose a language - we recommend Russian, as in some firmwares the English interface may contain translation errors.

Follow the installation master:

1. Choose a country (Russia or Ukraine for the correct operation of TV programs).
2. Connect to a Wi-Fi network (or Ethernet if you use a cable).
3. Accept the license agreement (pay attention to the data collection points – they can be disabled later).
4. Select the source of the signal (e.g. HDMI 1, if you have a console or computer connected).

Important: If the TV doesn't find Wi-Fi networks, check if it supports 5GHz. The Mi TV 4S 43 model only works with 2.4GHz networks, unless it's updated to the latest firmware.

2. Image setting: brightness, contrast, color

By default, the Xiaomi Mi TV 4S 43 uses a factory image profile, which is often too bright or cold. To get natural colors, go to:

Settings → Display and sound → Picture → Image mode

Select one of the preset modes:

• 🌞 Standard - balance between brightness and naturalness (suitable for most tasks).
• 🎬 Cinema - warm tones, recommended for films.
• 🎮 Gaming – Minimum input delay, but there may be excessive saturation.
• 💡 Dynamic – maximum brightness, but the colors look unnatural.

For fine-tuning, go to Additional Settings and adjust:

• 🔹 Brightness: 45-55% for rooms with moderate lighting.
• 🔹 Contrast: 80–90% for deep black.
• 🔹 Color temperature: Warm for home viewing, Cold for office tasks.
• 🔹 Sharpness: 20–30% (high values add artifacts).

If the image is washed when moving fast, activate MEMC (Motion Compensation) in the Motion menu. However, this feature can create a soap opera effect - test on different sources.

Mode: Standard |Brightness: 45-55% |Contrast: 80-90% |Color temperature: Warm |Disable MEMC for movie-->

3. Sound tuning: bass, high frequencies, external speakers

The built-in speakers of the Mi TV 4S 43 (2×8W) provide average sound quality.

Settings → Display and sound → Sound

Basic parameters:

• 🔊 Sound mode: Standard (universal) or Cinema (enhanced bass).
• 🎛️ Equator: Increase 100Hz slider for bass, 10kHz for clarity of speech.
• 🔇 Night mode: limits volume and smooths out harsh sounds (useful for apartments).

If you connect an external sound system (soundbar, receiver), use the Optical output (S/PDIF) or HDMI ARC.

1. From the Sound → Digital audio output, select Auto or PCM.
2. Activate HDMI CEC in Settings → System → Device Management to Control the Sound from the TV Remote.

Critical: When connected via HDMI ARC, the sound may disappear when switching sources. Solution: Turn off and re-enable ARC in the TV settings.

💡

If the sound is late when viewing via HDMI, check the audio delay settings in the Sound menu → Lip/sound sync. Optimal value: 0–50 ms
