How to use

Attach video sources via HDMI or USB Type-C for single-cable media and power where supported; use the USB 2.0 port for local media playback. Configure network control through the LAN port or RS232 for integration with AV control systems and deploy Neovo Controller software to manage settings such as input source, brightness and scheduling across multiple displays. Use the built-in speakers for ambient audio or connect an external sound system via the audio-out jack if higher volume or separate audio routing is required.
Usage recommendations
To maximize display lifespan and image quality, enable the Anti-Burn-in™ features, avoid prolonged static full-screen images when possible, and schedule periodic content variation. For installations in brightly lit areas, keep the anti-glare surface clean and set brightness appropriately to balance visibility and energy usage. Use centralised management for multi-screen deployments to ensure consistent settings and firmware updates.
