Description / Functional highlights
ANTI‑REFLECTIVE SCREEN
The optical bonding removes the air gap between the LCD and front glass, reducing internal reflections, improving contrast and making the front surface easier to clean and disinfect.

COLOR CORRECTION — WIDE GAMUT & HDR
The 10‑bit panel supports about 1.07 billion colors for wide color gamut and precise calibrated output. Includes DICOM Part 14 compliance and selectable gamma presets (1.8–2.6) for clinical image consistency.

MULTIVIEW DISPLAY
Supports dual‑screen, quad‑split, picture‑in‑picture and picture‑by‑picture modes. In multiview mode, image settings (for example gamma or DICOM preset) can be applied to selected inputs.

AUTO INPUT SELECT MODE
Automatically identifies and switches to alternate inputs if the active signal is interrupted due to system error or external interference, ensuring continuous display availability.

IP54 FRONT PANEL
The IP54 front enables safe cleaning with alcohol or water‑based disinfectants while maintaining ingress protection suitable for clinical environments.

CABLE SHIELD & CONNECTOR LAYOUT
Connector and cable management design reduce contact between cleaning solutions and connectors, limit exposure to corrosion and help keep cable routing tidy and secure.

OTHER FUNCTIONS
Offers flexible monitoring options and presets to support complex clinical workflows in addition to calibrated color performance and hygiene‑oriented design.
