The use of an ultra-narrow bezel and accurate colour reproduction enable a beautiful and natural large-screen display

The ultra-narrow bezel that makes the boundary line of the screen less conspicuous
The non-display area (top, bottom, left, and right) of the UN552S/UN552VS is only 0.44 mm in width. The ultra-narrow bezel makes the boundary line of the screen less conspicuous even in a multiscreen configuration and enables a natural display similar to a single image.

Enhanced calibration before shipping reduces installation time
Colour calibration that covers brightness and colour irregularities on the screen at each step of manufacturing means uniform colour reproduction when screens are installed together. Easily noticeable colour variations in areas where screens meet has been reduced when compared with existing products.
Furthermore, even in the case of colour calibration settings based on your colour sensors, calibration can be finished in an even shorter time.

Equipped with the SpectraView® Engine, NEC’ s unique colour correction function
When there is a change to a different colour setting, the image colour can be configured without colour variations by an on-screen display operation via the remote control.
This is intended to reduce the colour matching time compared to calibration using a colour sensor. Furthermore, the display is equipped with various colour conversion functions, such as emulation of representative colour spaces*.
* Adobe® RGB, sRGB, ITU-R BT.709, etc. The colour spaces may not be fully covered.

Reduce colour variation between screens due to long-term use
Screen colour changes that advance with temperature changes and long-term use are corrected automatically by a built-in sensor and the SpectraView Engine colour correction function. They maintain stable performance and reduce the burden of complicated calibration work. The UX series models are equipped with a backlight sensor for even more advanced correction.

The corner colour correction function* enhances colour matching
Based on the screen state after irregularity correction was performed before shipping, the areas around the four corners of the screen where colour drift can be very conspicuous can be colour adjusted independently. When further fine adjustments are required, each point on the screen can be measured using an optional external colour sensor to correct the screen automatically as well.

The standalone calibration function enables colour correction without use of a PC or dedicated application
The built-in standalone calibration function enables calibration by connecting an optional calibration sensor to the display without using a PC or dedicated application. The display also has a “white copy” function, which automatically configures to near image quality based on the white colour of adjacent screens, which can make colour matching fast even when you do not know the reference colours.

Brilliant images are reproduced naturally through HDR signal input support
The built-in HDMI terminals support the display of HDR signals (Hybrid Log method and PQ method)*. Reproduction is natural even with images with large light and darkness differences. Furthermore, HDR gamma and colour gamut can be configured manually for incompatible terminals.
* HDMI terminal only. DisplayPort terminals and other terminals are not supported.

A full line-up of functions for impressive multiscreen setups

The built-in HDMI and DisplayPort input and output terminals support up to 4K video for faithful display of ultrahigh resolution video
The built-in HDMI and DisplayPort input and output terminals support 4K video QFHD (3840×2160) signals. High-resolution 4K image daisy chaining is supported, resulting in an impressively large screen that does not spoil the quality of 4K video, even in a multiscreen setup.

A simple tile matrix configuration that reduces troublesome setting operations for each display
If daisy-chain connections are used for the image and control cables between all of the displays in a multiscreen setup, it is possible to press the execution button on one display and configure the remaining displays, which can simplify configuration for multiscreen setups.

The frame compensation function and vertical scan reverse function prevent image shifts that are characteristic of multiscreen setups
These two functions improve the image shift (misalignment) between displays joined in columns, which occurs when playing back high-speed video on a multiscreen setup. Frame compensation adjusts the image display timing of each frame, and the vertical scan reverse function inverts the image scan orientation of displays joined in columns alternatively, resulting in a natural video display.

Advanced heat management
Monitoring and managing the temperature of each display is crucial to secure reliability and longevity. An industrial-strength, premium-grade panel with additional thermal protection, internal temperature sensors with self-diagnostics, and fan-based technology allows for 24/ 7 operation, and protects your display investment. NEC's advanced heat management ensures uniform heat dissipation. Without heat management displays placed higher on a wall sustain more heat.

This highly durable display supports dual power supplies, so an external power source can be connected for the redundancy required for monitoring usage

- Redundant power supply for increased reliability
Installing an optional external power supply unit provides a redundant power supply. Even when there is a problem with the power supply built into the display, the operation of the display can be recovered quickly.

- Automatic screen correction maintains a stable display
The built-in backlight sensor detects changes in brightness and colour of the backlight over time. Corrections occur automatically in one-second cycles, and accurate colours can be maintained for a long time.
