Stunning visibility for presentations and digital signage

Enhance your meeting and conferencing performance with stunning UHD resolution. Get high-end quality and reliability at a low total cost of ownership with long life-times.

Professional haze levels ensure great visibility without distracting reflections - along with brightness of up to 350 cd/m², the NEC MultiSync C Series meets the demands of today’s meeting environments. Slim bezels and a modern appearance complement state of the art architecture to integrate perfectly into interior designs. With embedded office functionalities, start up ad-hoc meetings without the hassle of setting up the display environment first. Wake-up on connection is just one of many features which make meetings more efficient.

With the NEC MultiSync C651Q, presenters will feel confident during meetings of up to 8 participants whilst retailers and hospitality facilities can boost sales through digital signage.


  • Future Ready with Open Modular Intelligence Expansion – upgrade the power of your display at any time by seamlessly integrating one of NEC’s options for OPS Slot-in PCs, Raspberry Pi compute modules or signal interfaces for content feed and computing.
  • Ease of use and operation – smart installation, operation and maintenance functionality ensures accurate performance over the entire lifetime of the display saving time, effort and resources.
  • Future-proof signal connectivity and processing – numerous native UHD resolution inputs with 60Hz refresh rate including DisplayPort, HDMI and an option slot for OPS Slot-in PCs, plus automatic upscaling to UHD for other signals, provide “pixel-free viewing“ on a large scale.
  • Cost Saving Device Management – save effort whilst managing all connected NEC devices from a centralised location by using the NaViSet Administrator 2 software tool.
