Advantages

This professional display supports CMND and Control for centralised monitoring and input management over a local LAN, and FailOver to automatically switch between primary and secondary inputs to avoid blank screens. The integrated SmartPlayer media player lets you schedule video, audio and images directly from a USB drive, waking the display from standby to play scheduled content and returning it to standby afterwards. IPS panel technology ensures consistent image quality and wide viewing angles suitable for public and corporate spaces.

How to use

Install the display using a compatible VESA mount or place it on a suitable stand and connect power and source devices. For network management, connect the display to your LAN and configure CMND and Control to manage inputs and monitor status across one or multiple screens. To use SmartPlayer, save media files (video, audio, images) to a USB stick, insert it into the display, create a playlist and schedule playback through the on-screen menu. Configure FailOver by setting a list of alternative inputs so the display automatically switches if the primary source fails.

Recommendations

For reliable long-term operation, place the display in a well-ventilated area, avoid direct sunlight on the panel, and use quality USB media for scheduled playback. Regularly update network management settings and test FailOver sequences to ensure continuous content delivery.
