PN-U553 / PN-U473 /


Around-the-Clock Communicators with Streamlined Style, Versatile Installation

Excellent Image Quality

A brightness of 700 cd/m2 (PN-U553/U473) or 500 cd/m2 (PN-U423) supports these LCD monitors in their digital signage duties. And PN-U553/U473/U423 monitors boast 1,920 (H) x 1,080 (V)-pixel full-HD resolution to ensure that none of the detail or visual impact is lost. Thanks to full-HD resolution, everything from fine text to intricate graphics is stunningly crisp and clear.

Thin, Lightweight Design

PN-U553/U473/U423 monitors owe their exceptionally thin profiles to edge-lit LED backlighting, where LED elements are located at the edges of the panel. Streamlined for a pleasing appearance and minimal protruding parts, these monitors measure only 57/55/57 mm at their thickest point and weigh only about 25/19/16 kg, making for easy and fiexible placement in offices, public spaces, stores, and other commercial establishments. The stylishly thin profiles also enable attractive wall mounting.

Energy Efficiency

Edge-lit LED backlighting on PN-U553/U473/U423 monitors helps ensure reliable performance with low power consumption. In fact, PN-U553/U473/U423 monitors consume significantly less energy than conventional CCFL-backlight displays.

* PN-U423/PN-E421 comparison is based on power consumption for PN-U423 at 500 cd/m2 and PN-E421 at 700 cd/m2.

Choice of Installation Mode

PN-U553/U473/U423 monitors offer a choice of landscape or portrait installation, allowing customers to select the mode that best suits their display content and application. While portrait installation offers the look and impact of a poster, landscape installation puts wide images on vivid display.

Image Functions

Mirror Display Mode (Daisy Chain) *

With Mirror Display mode, the same image can be displayed on a daisy chain of these LCD monitors for the powerful impact of visual repetition.

* Via a DVI-D connection.

Mirror Display Mode (Daisy Chain)

Enlarge (Zoom) Display Mode
Multiple monitors can be grouped together to display one enlarged image, thanks to Enlarge (Zoom) Display mode, which corrects the framing of that image to eliminate misalignment between monitors.

User-Friendly Design

Built-In Speakers
Ideal for conveying audio information and playing location-appropriate background music, PN-U553/U473/U423 monitors feature built-in 10W + 10W rear speakers that eliminate the need for external speakers and ensure a stylishly streamlined profile.
Expanded Connectivity
A comprehensive range of input/output terminals, including the DisplayPort interface, comes as standard on PN-U553/U473/U423 monitors to give customers a variety of connection possibilities.


24/7 Operation
Built solid, PN-U553/U473/U423 monitors are ideal for use in demanding professional applications that require around-the-clock operation seven days a week.
Power on Delay

The Power on Delay function allows a time delay between the startup of each monitor in multi-monitor installations. This reduces the load placed on the power supply when a number of monitors are turned on at the same time.

Fanless Architecture

Fanless architecture maintains airflow and dissipates heat without the use of mechanical air-ventilation fans, which can attract dust and create noise. This fanless design also facilitates monitor maintenance.

Built-In Temperature Sensor

Should the temperature inside a monitor rise, a built-in sensor will detect it, and the monitor will automatically lower the brightness level of its backlight system.

Display Management

ID Setting

Thanks to an RS-232C interface, PN-U553/U473/U423 monitors* can be easily controlled and monitored from a central location via a PC. Each monitor can be assigned an individual ID code to specify when remotely turning that monitor on or off, changing its input, or making various screen adjustments and settings.

RS-232C straight cable

* PN-U553/U473/U423 monitors can be connected together in a daisy chain configuration.

For total ease of operation, the Schedule function allows up to seven settings to be pre-programmed for automatic monitor turn on/off at precise times on a daily, weekly, or one-time basis.
Web Browser Setting

Sharp LCD monitors can be easily operated through a Web browser and Display Management Tool software.*

  • * Available separately
Self Adjust Function
With an analogue PC connection, when a change occurs to the input signal timing, the clock phase will automatically adjust accordingly.
