Xiaomi 12T Pro

screen-refrequency

Many users confuse screen refresh rates (measured in hertz, Hz) with frame rates in games or video (FPS). These are actually related but different concepts: the screen frequency determines how many times a second the display updates the picture, and FPS - how many frames per second the GPU outputs. In Xiaomi 12T Pro, these parameters can be flexibly adjusted, but not everyone knows how to do it correctly.

If you are planning to buy this smartphone or already own it, this article will help you understand the intricacies of working with the 120-hertz AMOLED- display, which is one of the main advantages of the model. We will also test the real frequency in games and compare it with competitors.

Technical characteristics of the screen Xiaomi 12T Pro: official data

According to the manufacturer’s specifications, the Xiaomi 12T Pro is equipped with a 6,67-inch AMOLED- display with support for refresh rates up to 120 Hz. This means that the screen can update the picture to 120 once per second, which provides smooth interface scrolling, more responsive input and improved perception of dynamic scenes in games or videos.

Key screen parameters:

📱 Type of matrix: AMOLED, 10-bit (1.07 billion colors)
🔄 Update frequency: 1-120 Hz (adaptive)
🎯 Resolution: 2712 × 1220 pixels (FHD+)
🌈 Support for HDR: Dolby Vision, HDR10+
🛡️ Protection: Gorilla Glass 5

Importantly, the screen supports AdaptiveSync, which means that the smartphone automatically adjusts the amount of hertz depending on the content: for example, when reading text, the frequency can decrease to 1 Hz to save battery power, and in games – rise to 120 Hz for maximum smoothness.

The officially stated frequency of 120 Hz is confirmed by tests and reviews, but some users face limitations in certain applications.

How to check the actual screen refresh rate

To make sure your Xiaomi 12T Pro is really 120Hz, there are several methods you can use: the easiest is to use built-in settings or third-party apps.

Method 1: Through smartphone settings

Open the Settings → Display.
Select the screen refresh rate.
Make sure you have a 120Hz or Adaptive value set.

Method 2: Using applications

To check more accurately, you can use tools like Display Tester or Screen Refresh Rate Tester (available on Google Play), which show the actual refresh rate at the moment, rather than simply displaying system settings.

Method 3: Test with camera

If there are no applications at hand, you can use the strobe effect:

Turn on the white screen on your smartphone (for example, by opening an empty document).
Point the camera of another phone to the screen of Xiaomi 12T Pro.
If the frequency is really 120 Hz, the bands (artifacts of strobing) will be visible in the video.

⚠️ Warning: Some apps (e.g. YouTube or Netflix) may force the screen to limit to 60Hz even if the settings are set at 120Hz. This depends on the developer’s policy and is not a smartphone malfunction.

120 Hz vs 60 Hz: What’s Best for Xiaomi 12T Pro

The high refresh rate (120 Hz) gives you a smoother picture, but it also has the downside of increased power consumption. Let's compare the pros and cons of different modes:

Parameter	60 Hz	120 Hz
Smoothness of the interface	❌ Average	✅ Maximum
Autonomous time	✅ Longer by 15-20%	❌ Short (especially in games)
Heating the device	✅ Minimum	❌ Increased with prolonged load
Support for games	❌ Limited 60 FPS	✅ Up to 120 FPS (if the game supports)
Effect on the eyes	✅ Less fatigue	⚠️ Discomfort with prolonged use

For most tasks (social networks, instant messengers, video viewing) 60 Hz will be quite enough, but if you actively play PUBG Mobile, Call of Duty: Mobile or Genshin Impact, then 120 Hz will give a noticeable advantage in responsiveness.

Adaptive mode (automatic switching between 1-120 Hz) is the gold standard for balancing performance and autonomy. In the Xiaomi 12T Pro, it works well, but can sometimes go off with a delay (for example, it doesn’t immediately increase the frequency when you start a game).

💡

If you notice that the screen is slowing down when you move from one application to another, try manually setting a fixed 120Hz in the settings. This will eliminate delays but reduce battery life.

How to turn on 120 Hz on Xiaomi 12T Pro: step-by-step instructions

By default, the Xiaomi 12T Pro can be set to adaptive mode or 60 Hz. To manually activate the maximum frequency, follow the following steps:

Open the Settings.|Go to the Display section.|Select the Screen Update Frequency|Set the value of 120 Hz or Adaptive|Reboot your smartphone (optional)-->

If the screen refresh rate is not in the menu, it can mean:

🔧 The smartphone has a custom firmware installed that has removed this option.
📱 The device is in power saving mode (disables high frequencies).
🔄 In some regions (e.g. China), settings may differ.

For games, it is also recommended to activate the performance mode:

Go to Settings → Special Opportunities → Performance Mode.
Enable the option of High Performance.
In some games (such as PUBG Mobile), additionally adjust the graphics to 90 FPS or 120 FPS in the game settings menu.

⚠️ Warning: Forced 120Hz on games that are not optimized for this frequency can cause overheating or accelerated battery discharge. For example, Genshin Impact at maximum settings at 120Hz discharges a smartphone in 1.5-2 hours.

Update Frequency in Games: What You Need to Know

Xiaomi 12T Pro is equipped with a Snapdragon 8+ Gen 1 processor that is capable of pulling many games to 120 FPS, but there are nuances. Not all games support high frame rates, and some limit it to 60 FPS or 90 FPS.

Here is a list of popular games and their support for high frequencies on Xiaomi 12T Pro:

🎮 PUBG Mobile: up to 90 FPS (setting in the graphics menu).
🎮 Call of Duty: Mobile: up to 120 FPS (required to be enabled in game settings).
🎮 Genshin Impact: up to 60 FPS (engine restriction).
🎮 Fortnite: Up to 60 FPS (on Android, it doesn't officially support 120Hz).
🎮 Honor of Kings (Arena of Valor): up to 120 FPS.

To check the actual FPS in the game, you can use:

📊 Built-in frame counter (if available in game settings).
📱 Applications like GameBench or FPS Meter.
🎥 Screen recording followed by analysis in a video editor.

It is important to understand that even if the game supports 120 FPS, the smartphone may not hold this frequency consistently due to heat limitations. Xiaomi 12T Pro uses a cooling system with a steam chamber, but with long sessions, performance drawdowns (trottling) are possible.

How to reduce trolling in games?

1. Use a game cooler or play in a cool room. 2. Close all background apps before starting the game. 3. Set an FPS limit of 90 instead of 120 - this will reduce the load. 4. Turn off unnecessary visuals in the game settings (for example, shadows or reflections). 5. Update the firmware to the latest version - the new versions of MIUI optimized heat policy.

Screen frequency issues on Xiaomi 12T Pro and their solutions

Some users are faced with the fact that the screen Xiaomi 12T Pro does not switch to 120 Hz or is unstable.

This may be related to:

🔄 Power saving mode (turn it off in Settings → Battery).
📱 Failure to work MIUI (resetting screen settings will help).
🔧 Cast Firmware (return to official MIUI).

Problem 2: In games, the FPS sinks below 120

Possible causes:

🔥 Overheating (check the temperature via AIDA64).
🎯 Game restrictions (not all titles support 120 FPS)
📶 Background processes (close unnecessary applications).

Problem 3: The screen flickers at 120Hz

This may be related to:

👁️ Individual eye sensitivity (try to lower the frequency to 90 Hz).
🔧 Matrix malfunction (refer to the service center).
📱 shell conflict MIUI (update firmware).

If none of these methods worked, try resetting (without deleting data):
