• 📺 Incorrect zoom settings (overscan) – TV or smartphone cuts the edges of the image, creating the illusion of a bandwidth.
• 🔄 Firmware failure – after updating the software, display parameters may be lost, especially on Mi TVs TV Android TV.
• 🎮 Game monitor mode – activated automatically when connecting consoles (PS5, Xbox) and cuts the bottom of the screen.

• 🛡️ Use screen-protected cases for smartphones (e.g. Xiaomi Original Case).
• 🔌 Connect your TV to external devices with certified cables only HDMI.
• 🔄 Update your firmware regularly, but don’t install beta versions on your main device.
• 💧 Avoid moisture – even condensation can cause contact oxidation.
