Double screen on Redmi Note 7: how to enable and configure the split display function

The dual screen (or split display) feature on the Xiaomi Redmi Note 7 allows you to work with two applications simultaneously โ€“ for example, chat in the messenger and watch videos, or copy text from the browser into notes. MIUI This option is not always available out of the box, it can be activated in several ways - both standard and using hidden firmware capabilities.

In this article, we will discuss all working methods for enabling dual screen on the Redmi Note 7 (including the Redmi Note 7 Pro models), taking into account the version of the new version. MIUI (10 to 14) and firmware type (global, Chinese, custom) will also help you to fix common bugs when the feature is down and what alternative solutions exist for multitasking on this smartphone.

We warn you beforehand that some methods require developer rights or system files to be modified, and if you're a beginner, start with the simplest methods and then move on to the most advanced ones.

What is a dual screen and why you need it on the Redmi Note 7

The Split Screen mode divides the smartphone display into two independent areas, each of which can run a separate application.

  • ๐Ÿ“ Multitasking: work with documents and correspondence at the same time, or copy data between programs.
  • ๐ŸŽฅ View content: watch videos on YouTube and chat on Telegram, or follow the broadcast and comment on it.
  • ๐Ÿ“Š Comparison of information: open two browsers for data analysis or two messengers (for example, WhatsApp and Viber).
  • ๐ŸŽฎ Gaming streams: play and follow the chat in Discord (although for games it is not always convenient because of the small screen).

On the Redmi Note 7, the feature is implemented through a gesture of control (swipe up with retention) or through the menu of recent apps. However, in some firmware, it is disabled by default โ€” especially in global versions. MIUI This is due to performance optimization: dual screen increases the load on the Snapdragon 660 processor, which can lead to slowdowns on weak configurations.

It is important to understand that not all applications support split mode, for example, many games and some banking applications block this feature for security reasons or due to technical limitations.

Checking for dual screen support on your firmware

Before you try to enable the feature, make sure your version is MIUI It supports it:

  1. Open the Settings. โ†’ The phone.
  2. Find the MIUI version line (e.g. MIUI Global 12.5.3).
  3. Remember or write down this information โ€“ it will be necessary to choose the right method.

Next, check if the feature is active in the menu of recent apps:

  1. Open any application (such as Chrome).
  2. Click on the square button (recent menu) and hold the app icon at the top.
  3. If the words โ€œRun in split modeโ€ appear, the function is already available.

If you do not have the option, use the compatibility table:
