The NEC MultiSync UN series sets the standard for video wall technology. Featuring a minimal 3.5 mm bezel these display modules create impressive high resolution video walls with barely visible image gaps. With perfect picture quality and high product reliability, these displays are designed for the rigors of 24/7 operation. At a high brightness level of 700 cd/m² your message will be well received with effortless readability even in the brightest ambient light conditions. An advanced set of intelligent features make the displays easy to install and operate and support significantly reduced maintenance requirements. The 55” display is ideally suited to create huge screen surfaces for fixed installations and for mid and longer viewing distances.
NEC's vast experience in the video wall market is evident in the design with features that reduce costs, ease installation and enhance the visual impact of content in control rooms, broadcast studios, transport installations and the rental market.
NEC SpectraView
Colour Critical Viewing
The ideal display for all creative professionals, designers, photographers, videographers, broadcast engineers and anyone who cannot accept compromise on colour accuracy.
Differences between models
-
UN552: This model has a bezel gap of 3.5 mm, making it suitable for general video wall applications.
-
UN552S: This model features an ultra-narrow bezel with a combined bezel gap of 0.88 mm (0.44 mm on each side). It's designed for creating nearly seamless video walls with minimal visible gaps.
-
UN552V: Like the UN552, this model has a bezel gap of 3.5 mm. However, it focuses on durability and reliability, with industrial-strength panels and features for 24/7 operation.
-
UN552VS: This combines the ultra-narrow bezel of the UN552S (0.88 mm) with the durability and 24/7 operation features of the UN552V
Maintaining consistent visualisation across time and surface
Enhanced calibration before shipping reduces installation time
Even before the displays leave the factory they are already calibrated to a standardised level of brightness and colour uniformity meaning visual performance across multiple displays is near perfect right from the moment of installation. Crucial for saving time, especially significant in large and complex projects, pre calibration enables swift and timely induction with immediate wow factor. To enable rapid out-of-the-box-setup, predefined picture settings match the requirements of standard applications such as signage.
Self-calibration ensures colour perfection
Utilising proprietary SpectraView engine technology, each display is equipped to self-calibrate by connecting an optional calibration sensor to the display without using a PC or dedicated application. A 'White Copy' function enables the settings to be copied to the adjacent display within the wall. Alternatively, image colour can be configured without a calibration sensor via remote control of the on-screen display settings to save time. The display is equipped with various colour conversion functions, such as emulation of representative colour spaces (Adobe® RGB, sRGB, ITU-R BT.709, etc).
Reduce colour variation due to long-term use
As the brightness and colour temperature of the LCD naturally change over time, colour drift occurs typically around the corners of the screen. The NEC Display Wall Calibrator software ensures colour uniformity and fidelity across the entire surface to ensure a perfectly matched image in tiled environments. The Display Wall Calibrator function works twice as fast as in previous generation displays.
Time Saving set up during installation
The time and cost saving achieved using the NEC TileMatrix feature cannot be underestimated, especially for larger video walls and multiple video wall roll outs.
By configuring the settings on the first display only, Auto TileMatrix automatically copies the settings across all the remaining displays in the wall via the daisy-chain function.
Operational reliability through heat management
For multiple screen configurations where heat build-up can be a major issue, monitoring and managing the temperature of each display is crucial to secure reliability and longevity. Without heat management, the displays located higher in a wall will be subject to higher temperatures than those below leading to reduced picture quality and lower life expectancy of the product.
To counter this, NEC’s unique advanced heat management system secures efficient heat dissipation to maintain a uniform overall temperature. An industrial-strength, premium-grade panel with additional thermal protection, plus internal temperature sensors with automatic fan-based technology protects the display for 24/7 operation over its guaranteed long life.
Simplified signal management for faithful playback of UHD resolution video
The built-in HDMI and DisplayPort input and output terminals support signals up to 4K UHD video (3840×2160). Even on the largest multi-screen wall, 4K UHD rendition remains pin sharp as TileMatrix supports daisy chaining of the native UHD resolution across the entire video wall without loss of quality.
Embedded media sources ease set-up and operation
Sharp/NEC’s Open Modular Intelligence (OMi) platform provides an even smarter and seamless connection between source and display with computing power embedded within the display for a neat and efficient signage solution. It simplifies device installation, usage and maintenance whilst making it easier to upgrade digital signage equipment. The variety of interchangeable slot-in option products such as OPS Slot-in PCs and the OPS Digital Signage Player alongside adjustable performance levels allow custom-made solutions up to native 4K UHD resolution that are perfectly matched to individual demands.
Natural colour reproduction for superb life-like images
The built-in HDMI terminals support the display of HDR signals; with a broad display contrast widening the difference between light and dark elements, the result is intense detail and natural looking colours.
Homogeneous dynamic images across large screen surfaces
Where fast moving content is played back on a multi-screen arrangement, the image appears misaligned between the displays which causes a disruption to the viewers’ overall experience. Sharp/NEC’s frame compensation function and vertical scan reverse function prevents the image shifts that are characteristic of multiscreen setups, adjusting the timing of each frame, resulting in perfect content synchronization and smooth image delivery.
Reduced reflection for better visibility in high ambient light
Where displays are located in areas of high ambient light, typically in glass atrium buildings and shop front windows, light is reflected off the surface of glossy screens to greatly reduce the visibility of content.
Equipped with a professional haze filter, Sharp/NEC’s anti-glare panel scatters ambient light rather than reflecting it ensuring excellent visibility even in direct sunlight.
Reducing power consumption whilst enhancing signage perception
An optional ‘human sensor’ detects motion to automatically control display functions; turning on or off, or changing source inputs as an audience passes by, helping to save costs whilst creatively enhancing the delivery of signage. Auto dimming adjusts the backlight of the LCD automatically depending on the amount of ambient light to ensure consistent eye pleasing readability alongside economic power usage. This sensor can control the entire video wall via the LAN daisy chain or by controlling each display simultaneously.
Maintaining control of your assets
NEC’s NaViSet Administrator 2 software is an all-in-one remote support solution that operates from a central location and provides monitoring, asset management and control functionality of most NEC display and projection devices and Windows computers.
Especially convincing for multi-device installations over large estates, this functionality offers exceptional cost and resource saving potential, assisting administrators in managing efficient operation.
