How to Activate 3D Mode in 3 Steps

Immersive 3D Switching on CORNMI NeoVista

1. Prepare Your Content: While wearing the glasses in standard 2D mode, play a compatible side-by-side 3D MKV video. The screen will initially display two identical frames (left and right images).

2. Locate and Press the Mode Button: Find the circular button positioned at the tip of the left temple arm, near the eyeglass frame. Firmly double-press this button in quick succession – both taps should occur within 1-2 seconds.

1. Enjoy 3D: Immediately after the double-press, the system activates 3D rendering. The dual images seamlessly merge into a single, high-definition stereoscopic scene with depth perception on the virtual cinema screen.

Key Notes:

• Works only with properly formatted left/right 3D MKV files
• Double-press speed is critical (too slow = no response)
• No menu navigation required – the physical button provides instant switching
• To revert to 2D, simply double-press the same button again

This method delivers instant 3D immersion without software configuration, leveraging the hardware button for tactile, reliable mode switching. If 3D fails to activate, verify your video format and ensure quick button presses.
