LG ConnectedCare DMS
LG ConnectedCare DMS is a cloud solution for remotely monitoring, controlling, and managing the status of LG CreateBoard and TV signage devices installed in educational environments. This feature enables IT managers to operate and manage important resources on operating devices without physically visiting sites. LG ConnectedCare DMS needs to be purchased separately.
DMS Dashboard
The LG ConnectedCare DMS dashboard allows you to view and monitor multiple devices at the same time, thereby saving time and boosting efficiency. The Dashboard features include a summary of connection status and device issues, list of frequently used apps, no response status, checks of recent issue type, and a display of scheduling history for the previous seven days.
Remote Control
Frequently used controls such as the screen on/off, scheduling, brightness, and screen lock functions can be applied using a remote control. Additionally, IT managers can remotely install and update the apps on selected devices, which helps lessen the need for on-site response.
Broadcasting / Alert Messaging
Content such as images, videos, audio messages, and live streaming can be shared from the primary system to specific devices including UM340E and LG CreateBoard installed in the school. In case of urgent occasions such as a fire or a natural disaster, alert messages can be distributed manually across the system, which helps teachers and students promptly take safety action.
Threshold Settings
Users can set thresholds including CPU temperature, memory usage, or available storage, and can receive warning or error notifications based on their threshold settings.
Monitoring & Fault Diagnosis
An engineer can check the status in real-time and diagnose problems remotely. Also, the current status of issues can be categorized, allowing for easy viewing and quick responses.
Issue Management
Remote issue management can be carried out by the LG ConnectedCare DMS solution. This makes management safer and more efficient, facilitating the stable operation of the classroom.

LG UM340E Reviews

Great TV

LG 50UM340E 50 UHD 4K Commercial TV took the place of my LG 48 inches that rigth now is my mane pc monitor.

Very limited capabilities

Overall I'm disappointed with this display. It's very lacking in basic things I'd expect of a commercial display, like powering on and off to a schedule. I could never get LG to respond to a request for an account in their management software, which seems to be aimed at schools or larger businesses anyway, not our one-off church lobby usage. None of the third-party apps I tried to use for content management worked, and I ultimately had to connect a Raspberry Pi to get content onto it, and that still can't turn the TV on and off over CEC. The manual is useless, it has no info about the TV's software or capabilities, other than a very obtuse description of control commands for direct IP control.
