Optoma N3552K Ecrã profissional 4K UHD IPS de 55 polegadas H1F2C0ZBW101

Where many commercial panels settle for Full HD, the Optoma N3552K steps up to native 4K UHD on a 55-inch IPS screen, delivering crisp detail and consistent colour from any angle. Built for 16/7 operation in retail, corporate, and education environments, it combines Android 8.0 flexibility with robust connectivity and a slim, professional bezel.

In daily use

Deploy the N3552K in meeting rooms, digital signage networks, or classroom settings. Its 16/7 duty cycle handles extended hours, while the Android platform allows installation of apps for content management, video conferencing, or interactive whiteboarding. The slim bezel (11.9 mm top and sides) minimises distraction in video walls, and the bottom bezel houses the IR sensor for easy remote control. Connect sources via HDMI or DisplayPort, manage the display over LAN or RS232, and use the USB ports for media playback or touch interactivity (with optional overlay). The built-in speakers reduce clutter, and the 3.5 mm jack or S/PDIF can feed external audio systems when needed.
