Left-handed image shifting (called left-hand screen) is a common problem on Xiaomi devices that can be seen on both smartphones and the brand’s TVs, where users are faced with a situation where part of the picture is cropped off on the right side, and a black bar appears on the left or the edge of the screen is duplicated, and the reasons for this behavior range from incorrect zoom settings to hardware malfunctions of the matrix or graphics processor.

In this article, we'll look at all the possible ways to fix the problem, from basic settings in the device menu to complex firmware manipulations. We'll focus on diagnosing the cause, because the wrong "treatment" method can make things worse. For example, resetting to factory settings will help with a software failure, but will be useless if the display plume is physically damaged. Ready to return the screen to normal? Let's start with the simplest one.

Reasons for the left-hand shift on Xiaomi

• 🔧 Incorrect display settings: manually adjusting resolution, refresh rate, or display mode (e.g. activating Frameless Mode on TVs).
• 🔌 Hardware problems: damage to the display plume (relevant for smartphones after falls), malfunction of the graphics chip or matrix.
• 🖥️ External devices: Connecting to the TV through HDMI with incompatible signal parameters (e.g., resolution) 4K@120Hz on older models).
• 🔄 Conflicts after firmware: installing custom ROM Unofficial patches that are not optimized for your model.

On Xiaomi Mi TVs TV The problem is often associated with automatic zooming — the function tries to "fit" the picture to the size of the screen, but wrong with the calculations.
