Xiaomi smartphone owners often encounter a mysterious option in screen settings or when launching a video player, which is called a VR-rem. For the Redmi Note 9 Pro, this feature is not just a marketing ploy, but a full-fledged tool for splitting the display, which turns a normal picture into a stereoscopic image. Understanding the principle of this technology allows you to unlock the potential of the device to view content in virtual reality glasses.
In fact, VR Mode is a software algorithm that divides an image into two identical frames side by side. Each eye sees its part of the picture through the lenses of glasses, creating the illusion of depth and volume. 9 Pro with its quality IPS-high-resolution screen 2400×1080 pixels, the immersion effect is quite convincing, if you choose the right content.
Many users mistakenly believe that the function requires complex system settings or superuser rights. In fact, the MIUI already contains all the necessary tools to activate, the main thing is to know where to look for the switch and what video content is capable of supporting split-screen technology.
⚠️ Warning: Long-term use of split screen mode can cause rapid eye fatigue and dizziness. Take breaks every 20-30 minutes of use.
The principle of virtual reality on a smartphone
The technology used by Xiaomi is based on the Side-by-Side (SBS) method, which divides the screen vertically in half, and the video processor displays the left image for the left eye and the right image for the right eye, special glasses with lenses focus each light stream on the corresponding eye, and the brain combines them into a single three-dimensional picture.
The key element here is a gyroscope built into the Redmi Note 9 Pro motherboard, which tracks the user's head turns. When you turn your head left or right, up or down, the sensor transmits the coordinates to the application, and the image on the screen shifts accordingly, creating the effect of presence indoors or landscapes.
It is important to understand the difference between the present VR-It's a real-time rendering of three-dimensional environments, which requires a lot of Snapdragon processor resources. 720G. In the second case, the phone simply displays a pre-prepared video sequence, which is less demanding on the system, but also effective for consuming media content.

How to Enable and Configure VR Mode
Activation of the feature on the Redmi Note 9 Pro can occur in two ways: automatically through compatible applications or manually through system settings. Most often, users find this option in the Mi Video video player menu or in the special features settings.
To manually enable, you need to go to the settings menu. Find a section related to display or special functions. In some versions of MIUI firmware, the switch may be hidden in the Features subsection or called by a swipe in the control panel. If standard methods fail to find an option, it is worth checking for system updates.
☑️ Pre-insertion check VR
Once activated, the screen will split into two parts. If the image looks stretched or the colors are unnatural, calibration may be required. VR settings menu often features a lens spacing slider (IPD), although at the software level Xiaomi rarely gives deep access to these settings, relying on Google Cardboard standards.
Compatible content and applications
By itself, the on mode will not do anything if you run a regular YouTube video. To get the effect of volume, you need special content labeled with 3D, VR or 360°. Without the original stereoscopic material, you will see just two identical copies of a regular video.
There are a number of applications that work perfectly with the Redmi Note 9 Pro in conjunction with the VR-They automatically recognize the mode and switch the interface to split screen:
- 🎬 YouTube VR — official application with a huge database of panoramic videos and 3D-film.
- 🎮 Google Cardboard – a platform for running games and viewing photos in virtual reality.
- 🎥 VLC for Android – a powerful player that can forcibly turn on the mode SBS for any video file.
- 🌍 Google Earth VR — Virtual travel on a world map with the effect of presence.
When using third-party video players like MX Player or Kodi, you can often find a display mode switch button in the play menu. Look for an icon that resembles glasses or two rectangles. Pressing on it will force the screen to split even if the video file is not marked as 3D, although the depth of the flat video will not appear.
Using a gyroscope for navigation
The central element of interaction in the virtual environment is the gyroscope. The Redmi Note 9 Pro has a high-precision sensor that allows smooth tracking of movements. VR-It should be calibrated in mode.
If you turn your head, it floats, it's late, or it doesn't move, calibrate it, and then go to the Advanced Settings section of your phone, and find the "Gyroscope Calibration," and put it on a perfectly flat horizontal surface, and press the start button.
Some games or applications may require additional calibration inside the software itself, usually by pointing the crosshairs at a special tag and confirming the action, and without the proper operation of the gyroscope, immersion in virtual reality is impossible, because you will not be able to look around.

Comparison of performance in VR mode
Working in split-screen mode and rendering 3D-The graphics put additional strain on the Adreno 618 graphics accelerator, and although the Redmi Note 9 Pro is a mid-budget product, it does quite well with the basics. VR-However, it is important to consider the possible limitations.
When used actively VR-The mode can be faster battery discharge and heating of the case. This is due to the fact that the brightness of the screen is often twisted to the maximum to compensate for the dimming of the glasses, and the processor operates in enhanced mode to maintain a high frame rate.
| Parameter | Regular regime | VR mode (SBS) | Impact on the system |
|---|---|---|---|
| Rendering permission | 2400×1080 | 1200×1080 (by eye) | Average. |
| GPU loading | Normal. | Elevated | Possible heating |
| Battery consumption | Standard. | High (+25%) | Quick discharge. |
| Content requirements | Anybody. | Only 3D/360°. | Searching for files |
If you are planning to play resource-intensive VR-games, close the background applications, and that will free up RAM and reduce the likelihood of micro-twitching images that in virtual reality can cause nausea.
Typical problems and their solution
Xiaomi users may encounter a number of specific problems when trying to run virtual reality, one of the most common being a black screen with glasses when running an app, which often happens when an app can’t correctly identify the phone’s sensors or when power saving mode is on.
Another common complaint is the unsynchronization of sound and image or low frame rate, in which case it is worth reducing the quality of playback in the settings of the video player or game. buffering online video in high resolution can also be a cause of delays, so it is recommended to use local files or stable Wi-Fi.
⚠️ Note: Do not leave your phone in the room. VR-The glasses act like a magnifying glass and can cause the battery to overheat and even catch fire.
If the image is shaking or twitching, check if the increased smoothness mode is enabled in the screen settings, which may conflict with the refresh rate. VR-Sometimes cleaning up the cache of the Google app helps. VR Services.
💡
The stable operation of VR mode on the Redmi Note 9 Pro depends not only on the power of the processor, but also on the quality of the calibrated sensors and the optimization of a particular application.
