Create maximum visual impact through seamless simplicity with the new professional NEC C-series products.

Contemporary and slim mechanical design with focused aesthetics allows for smooth and stylistic integration into any type of environment. The NEC C-series boasts 400 cd/m2 brightness along with a new anti-glare surface that allows for efficient readability in normal ambient light situations and 24/7 applications are possible.


Modern and Slim Design

The new elegant slimline design provides unobtrusive integration into any application and environment. The simplicity of its shape supports an unhindered viewing experience ensuring that the screen content is the prevalent factor. Its reduced depth means that access to buildings and integration within interior design is straightforward and hassle-free.

Blue ON LED and Ambient Light Sensor

New mechanical structure allows for sleeker LED and ambient light sensor design. Auto dimming of the LED backlights can be utilized through the ambient light sensor allowing the brightness to change depending on the external lux in the room of installation.

The Media Player Function can Play and Display Movies and Images Saved on a Storage Device

By connecting a USB storage device or microSD memory card containing video data and image files, videos and images can be presented without a computer. This means that digital photos, videos, and music that teachers and students have recorded can be used in the classroom without disrupting the flow of the class. The display can also be used to display information and background videos in reception lobbies, lounges, waiting rooms, and other areas.

Built-in High-output 10 W + 10 W Stereo Speakers for Convenient Audio Playback

The built-in 10 W + 10 W stereo speakers can play audio signals from various video devices at a high volume to deliver clear sounds to a room.

Equipped with a Powered USB Port

The display is equipped with a powered USB port of 5 V / 2 A. Power can also be supplied to USB power-supply devices.

Supports Portrait Installations Suitable for Digital Signage

The display itself can be installed vertically, which widens the range of practical uses to include signage, such as signs and electronic guidance boards in public areas. In addition, the bezel width is symmetrical around the screen, and a function is included to rotate the settings menu projected on the display, so the display can be used without it feeling out of place.
