Why does the Xiaomi Curved Gaming Monitor G34WQi show black borders?

When using the Xiaomi Curved Gaming Monitor G34WQi, you can occasionally notice black borders appearing around the screen. This issue often occurs when switching between different display devices or when the monitor is connected to a new system. The black borders are usually caused by an incorrect screen resolution setting that doesn’t fully match the monitor’s native resolution.
To resolve this issue on the monitor, please refer to the following methods:
1. You can start by checking and adjusting the screen resolution in your system’s display settings. The recommended native resolution for this monitor is 3440 x 1440, which ensures a full-screen display without borders. Selecting this resolution will help the monitor display content correctly and utilize the entire screen area;
2. If you do not plan to use the 3440 x 1440 resolution, choose a resolution with the same aspect ratio to ensure proper screen scaling and avoid black borders.
