If your Xiaomi TV starts flickering, twitching, or giving out unpleasant artifacts when watching a video, the problem may lie in the wrong screen refresh rate. 50 Hz and 60 Hz are two standard modes that affect not only the smoothness of the picture, but also the compatibility with the content. But which one is better? And why does it sometimes flicker when switching between them?
Many users are faced with the fact that in the selection 60 Hz image becomes smoother, but there are jerks in European broadcasts (for example, football matches), and when 50 Hz – the picture is stable, but less dynamic. In this article, we will discuss how to eliminate flickering on Xiaomi Mi TVs. TV 4/4S/4A/5/5X/6, Redmi Smart TV and other models, and determine which mode of — 50 or 60 Hz – Optimal for your tasks.
Spoiler: There's no universal answer. The choice depends on the type of content (movies, games, TV broadcasts), regional standards, even your TV model, but there are clear criteria that will help make the decision, and we'll go through them in detail.
Why does Xiaomi TV flicker at 50 or 60 Hz?
Screen flickering isn't always a matrix defect, but it's often a problem with the difference between the refresh rate of the screen and the frame rate of the signal source.
🔹 Broadcasting Standards Conflict: Europe and Russia use standard PAL (50 Hz), and in the United States and Japan — NTSC (60Hz. If your TV is set to 60Hz, but you're watching a European broadcast, the picture will twitch because of the forced frequency conversion.
🔹 Adaptive Synchronization (Auto Low Latency Mode, ALLM): On some Xiaomi models with the enabled mode ALLM The TV automatically switches the frequency, which can cause a short-term flicker, especially in games when changing scenes.
🔹 Wrong settings HDMI: If the source (console, game console, media player) transmits a signal at a frequency other than the one chosen on the TV, artifacts arise. For example, the PlayStation 5 defaults to output 60 Hz, and if the TV is at 50 Hz, the image will "break".
🔹 Firmware problems: Older versions of Xiaomi software (especially on 2018-2020 models) had a dynamic frequency switching bug that caused flickering. MIUI TV 3.0.
🔹 Cables and connectors: cheap HDMI-cables or damaged ports can cause signal loss, which manifests as flickering. 4K@60Hz, where a standard cable is required HDMI 2.0+.
⚠️ If the flicker appears only when you turn on the TV and disappears after 5-10 seconds, the problem may be in the backlight (LED-It's a hardware malfunction, and it's not software-based.
50 Hz vs 60 Hz: Comparison of Different Content Types
To understand which mode is best, you need to consider what content you watch most often.
| Type of content | 50 Hz | 60 Hz | Recommendation |
|---|---|---|---|
| Etheric TV (DVB-T2) | ✅ Stable (PAL-standard) | ❌ Moving jerks | Use 50 Hz. |
| Movies (24 frames/s) | ⚠️ Possible artifacts during conversion | ✅ Better (most players convert 24)→60 without jerks) | Preferably 60 Hz with Film Mode enabled |
| Games (consoles, PC) | ❌ Notable lags and jerks | ✅ Smoothness, low input lag | 60Hz, absolutely. + game-play |
| YouTube, streaming (Netflix, Kinopoisk) | ⚠️ Depends on the source. | ✅ Most rollers in 60 fps | 60Hz for Modern Content |
| Sport (football, hockey) | ✅ European broadcasts in 50 Hz | ⚠️ Possible artifacts during conversion | Depends on the source of the broadcast |
💡 If you watch mainly on-air TV or European sports, choose the right one. 50 Hz. For games, movies and streaming is optimal 60 But there is a nuance: some Xiaomi models (for example, Mi). TV Q1/Q2) They support automatic frequency switching depending on the source.
How to enable automatic switching 50/60 Hz on Xiaomi TV

Twinkling while watching movies: how to fix the soap opera effect
When watching a 60Hz movie, many people notice an unnatural smoothness of movement, called the Soap Opera Effect, because the TV artificially increases the number of frames (interpolation) to fill the difference between the original 24 frames / s (the standard movie) and 60 Hz.
🎬 How to Remove the Soap Opera Effect:
- 📽️ Turn off frame interpolation: Go to Settings → Picture → Movement → Smoothness of movement and set off..
- 🎞️ Turn on Film Mode: In the same picture settings, find the Film Mode option and activate it. This will force the TV to handle 24 frames/s correctly.
- 🔄 Use 24Hz (if supported): Some Xiaomi models (e.g. Mi) TV Q1E) They allow you to put 24 Hz on the screen, which is ideal for movies, but not for games or TV.
📌 Important: If you watch movies through Kodi or Plex, you also need to turn off options like “Adjust refresh rate to match video” in the player settings (unless the TV supports automatic switching).
💡
For movies, 24Hz (if any) or 60Hz with interpolation turned off is optimal. For TV and sports, 50Hz is optimal.
Frequent errors when setting the frequency on Xiaomi TV
Many users exacerbate the flicker problem by making typical mistakes.
❌ Error 1: Use "Auto" in screen resolution
Auto mode in resolution settings can cause a constant switch between 50 and 60 Hz, which causes flickering. Always choose a fixed value.
❌ Mistake 2: Ignore the regional settings
If you live in Russia or Europe, but you have a U.S. region on your TV, the system will force you to use 60Hz, which will lead to a surge in your TV viewing. → System system → Region.
❌ Error 3: Connecting consoles via adapters
Use of adapters (e.g, HDMI → DVI) It can knock down a frequency signal. Always connect devices directly through the HDMI.
❌ Mistake 4: Turn off HDMI-CEC
Function HDMI-CEC (In the settings Xiaomi is called MI AnySee allows the TV to sync with connected devices, including frequency, and disabling this option can lead to conflicts.
❌ Error 5: Reset settings without updating the firmware
If the problem is caused by a software bug, resetting to factory settings without prior updates won't help - the error will come back. First update the TV!
