Create pixel-perfect imagery with the high-end panel quality of the fully professional NEC M Series large format displays. By focusing on customer needs while also offering professional reliability, the M series displays give customers a digital signage display lineup without all the costs. The M series can support both landscape and portrait orientations while also containing a Coffee Lake Intel Celeron Windows 10 IoT Enterprise PC through the SDM-VICW-IS seamlessly integrated into the SDM-L slot on the side of the display. The series contain a full metal mechanical chassis, allowing for a more robust design necessary for commercial applications while maintaining the attractive aesthetics that allow the focus of onlookers to be on what matters - the message. Simple and targeted connectivity options allow customers to have the up-to-date options that they need while not having to overpay for excess and unused interfaces. The NEC M series boasts 500 cd/m² brightness which is ideal for a majority of digital signage applications in corporate, higher education, restaurant, retail and grocery store environments when the focus should be on the message, not the budget.

  • 4K UHD native resolution allows for crystal clear imagery and messaging that become more vivid and lifelike than ever before
  • Landscape and portrait orientation allows for flexibility of installation dependent on your needs
  • Integrated Coffee Lake Intel Celeron, Windows 10 IoT PC with the SDM-VICW-IS included in the SDM-L slot

  • 500 cd/m2 brightness and HDR compatibilty will capture the attention of audience in almost any situation
  • Integrated media player allows for audio, video or image playback via USB
  • Failover capabilities with full input detect functionality allow peace of mind as the display will automatically switch to a secondary or tertiary source if the primary source fails
  • Integrated ambient light sensor allows the display to autmatically adjust its luminance based on external brightness conditions

Human sensor (large format displays)

Upon sending movement, allows for automatic adjustment to certain settings and features in the display which can lead to targeted messaging for dual-purpose display in digital signage or presentation applications.

4K resolution

Provides the ultimate in screen clarity.

Built-in speakers

Enhance the visual experience with superior sound.

Integrated ambient light sensor

Integrated ambient light sensor allows the display to automatically adjust its luminance based on the external brightness conditions, allowing for the ideal image in all ambient lighting scenarios.

Integrated ATSC/NTSC tuner through SDM-S slot

Additional tuner module integrated into the display that allows for FHD (1920 x 1080) ATSC or NTSC signal delivery. The tuner can be controlled by either the display's remote or the included RS-232C interface.

Round-the-clock scheduler

Allows for advanced scheduling of monitor powering up/down, increasing panel lifetime, reducing power consumption and saving the time and expense of finding and purchasing a third-party scheduling solution.
