How to use

Connect power and network via the supplied interfaces; use Ethernet for remote management and content distribution where available. Feed 4K content over compatible video inputs or a connected media player; if using USB-C or AV-over-IP accessories, ensure source devices and cabling support the display’s resolution and refresh rate. Configure basic display settings, scheduling, and network parameters through the on-screen menu or remote management tools before deploying content for continuous operation.

Recommendations

For optimal readability in bright environments, use high-contrast content and take advantage of the panel’s high-haze finish. When deploying in networked installations, enable enterprise security options and centralised monitoring to maintain uptime. Schedule regular maintenance checks for ventilation clearance and software updates to ensure reliable 24/7 operation.
