Active Resolution and Refresh Rate (60 Hz):
Installation and Mounting: The display requires proper installation using a VESA Standard wall mount (not included). It is crucial to ensure the mounting location can support the LCD's weight and that the installation angle is within 15 degrees of the vertical axis. For portrait orientation, the display must be rotated clockwise so the left edge becomes the top edge. Adequate ventilation is necessary, and the display should not be installed near flammable materials, heat sources, or in confined spaces.
Powering On/Off: The display is powered on/off using a main power switch located on the back. The remote control functions only when this main switch is in the ON position.
Connecting Video Sources: External video sources (PC or AV devices) are connected via DP or HDMI cables to the DP-IN, HDMI 1-IN, or HDMI 2-IN ports.
Input/Output Terminals: The display offers a comprehensive set of I/O terminals including AC (OUT/IN), Power Switch, USB ports (for flash drives, mouse, keyboard, and firmware upgrade), SD card slot, RJ-45 (network input), HDMI (IN), DP (IN), Audio (OUT), Thermal extension connector (for ETK202), Extension Connector (for ESK302), and RS-232 (IN/OUT) for remote control and daisy-chain applications.
Remote Control: The display can be controlled directly via its IR receiver (within 2.5 meters and a 100-degree angle) or through an optional External Sensor Kit (ESK302) connected to the mini USB port. Ambient light, especially from fluorescent or neon lights, may affect remote control performance.
Built-in Keypad: A built-in keypad provides basic control for OSD navigation, power on/off, and selection.
On-Screen Display (OSD) Menu: The OSD menu allows users to adjust various settings:
DSM365 Operating System: The display integrates DSM365, an Android-based OS, enabling the installation of applications from USB, SD card, or the internet. Users can switch to DSM365 via the Input Source menu. The DSM365 interface includes "APPS" to show installed applications and "SETTINGS" to enter the setting menu.
General Safety:
Cleaning:
Preventing Image Burn-in: Avoid displaying stationary or fixed images for prolonged periods to prevent permanent image imprinting (burn-in), which is not covered by the manufacturer's warranty.
Fastener Inspection: Regularly inspect fasteners for signs of loosening or deformation, especially in ceiling-mounted installations, and perform corrective measures as needed. Increase inspection frequency for areas with previous maintenance.
Troubleshooting: The manual provides a troubleshooting guide for common issues such as no image, unresponsive main switch, unstable image, remote control not working, auto on/off malfunction, and RS-232 control issues, offering recommended solutions like checking cable connections, power status, resolution settings, battery condition, and remote control range.
