The latest firmware update introduces OSD scaling, allowing hunters to perfectly align the on-screen display (OSD) with the field of view of their day scope – no matter the magnification.
This means menus and icons now appear proportionally adjusted, giving you a more natural, seamless experience through your optics.

How it works Simply press the first and third (color) buttons simultaneously to switch between four OSD scale levels:
👉 75% → 60% → 45% → 30%

Important

To access this new feature, please update your VIPER Gen 2 device with the latest firmware via NITEVISION app. Without this update, the OSD scaling function will not be available. Enjoy the next level of precision, comfort, and control – that’s the new VIPER intelligence.
