How to stretch the screen PUBG Mobile on Xiaomi: 5 ways to Redmi, POCO and Mi

Playing PUBG Mobile on Xiaomi smartphones can be even more comfortable if you adjust the display of the screen correctly. Many players face the problem of “black stripes” on the sides or suboptimal resolution, which interferes with full-fledged gameplay. Stretching the screen not only removes unnecessary bezels, but can also improve the view, which is critical in competition.

However, not everyone knows that the configuration of the stretch depends on the smartphone model, the game version and even the MIUI firmware. In this article, we will analyze 5 proven ways to stretch PUBG Mobile on Xiaomi devices, including hidden developer settings, third-party utilities and optimization through the gaming center.

It is important to understand that improper permission manipulation can lead to graphic artifacts or even account bans (if informal methods are used), so we will elaborate on safe ways and warn about possible risks.

Why PUBG Mobile doesn’t automatically stretch on Xiaomi

The reason lies in the policy of Tencent and the features of the firmware MIUI. The fact that PUBG Mobile by default adapts to the standard aspect ratios (16:9, 18:9, 19.5:9). However, many Xiaomi smartphones (especially the Redmi Note series and POCO) have non-standard resolutions or dynamic cutouts, which the game does not always correctly recognize.

Also, MIUI has a built-in Optimization for Games feature that sometimes blocks forced resolution change, which is done to prevent overheating and save battery power, but for gamers, such restrictions often become a hindrance.

• 🔒 Limitations MIUI: Firmware blocks forced stretching to save resources.
• 🎮 Settings PUBG: In the game itself, the option "Full screen mode" can be disabled".
• 🛠️ Lack of rights: Without Developer Rights included, some methods don’t work.
