Description

Engineered for reliability, this display utilises an industrial-level ADS LCD panel capable of running continuously without degradation. The factory calibration technology ensures high colour uniformity across multiple units, which is essential for large-scale surveillance or command centres. With a brightness of 500 cd/m² and a 1200:1 contrast ratio, the image remains clear and detailed even in well-lit environments common in Omani offices.

Connectivity is robust, offering HDMI, DVI, VGA, and BNC inputs alongside two HDMI outputs for daisy-chaining. The unit supports both infrared and RS232 control modes, allowing integration with existing computer systems. Its modular design permits floor-standing or wall-mounted installation using the standard 600×400mm VESA pattern. We provide tailored quotations covering hardware, delivery, and installation labour for sites across all 11 governorates.

Ideal for: Surveillance centres, command centres, corporate meeting rooms, and commercial display installations in Muscat and across Oman.

  • Ultra-Narrow Bezel – The 3.5mm bezel-to-bezel design minimises visual gaps, creating a near-seamless large-format display surface.
  • Continuous Operation – Built with industrial components to support 24/7 duty cycles, making it suitable for security and command centres.
  • Colour Uniformity – Factory calibration ensures consistent colour and brightness across the entire video wall, preventing patchy visuals.
  • Dual Control Modes – Allows management via infrared remote or RS232 serial connection for automated system integration.
  • Low Power Consumption – Consumes only 175W typically and less than 0.5W in standby, reducing operational costs over time.
  • Abundant Interfaces – Includes HDMI, DVI-D, VGA, CVBS, USB, and Audio ports for versatile source connectivity.
  • Modular Installation – Supports both floor-standing and wall-mounted setups via a standard 600×400mm VESA mounting pattern.
  • Thermal Management – Professional thermal design extends device lifespan by maintaining optimal internal temperatures during long sessions.
