UD55D - UD-D Series 55" Direct-Lit LED Display


The Samsung UD55D advances LCD video wall technology by reducing the bezel-to-bezel (BtB) spec from 5.5mm to 3.5mm compared to predecessor models. Along with factory-tuned color calibration for consistency across multiple displays and our embedded SMART Signage Platform (SSP), you can efficiently achieve seamless matrices, while LED backlighting reduces power consumption in large installations.

  • Ultra-Narrow Bezel Width at 3.5mm BtB for Virtually Seamless Video Walls
  • Embedded SSP System-on-Chip (SoC) Technology Can Eliminate the Need for External Media Players
  • Factory-Tuned for Color Uniformity Right Out of the Box

Product Features

3.5mm BtB Ultra-Narrow Bezel Width

The UD55D features incredibly thin bezels at a mere 2.3mm (L/T) and 1.2mm (R/B) - 3.5mm bezel-to-bezel - shaving more than 33% off its predecessor model. Create virtually seamless video walls for a more elegant and impactful delivery of your message.

Samsung SMART Signage Platform (SSP)

Embedded SSP SoC technology helps to reduce the cost and complexity of installation and maintenance by streamlining hardware and software requirements. As an integrated, open platform, you can eliminate the need for external media players to display content across video walls.

Color Calibration

Samsung factory color calibration helps to minimize color difference among mulitple LFDs. Factory-tuned for brightness, color temperature and gamma, you can experience color uniformity right out of the box for consistent video wall messaging.

Advanced Color Management (ACM)

The ACM solution provides a user-friendly interface to implement customized and detailed color adjustments. Control luminance, temperature and gamma through auto calibration, manual calibration and duplication to achieve the perfect display for your business.

Video Wall

Create video walls up to 10x10 for large, impactful messaging. Easily connect multiple displays in an elegant fashion thanks to the streamlined hardware and software requirements of the embedded SSP SoC technology and the ultra-narrow bezels of the UD55D.

Achieve UHD Resolution

Daisy Chain up to 4 displays over Display Port 1.2 (DP 1.2 - Loop-Out) to achieve 4K x 2K Ultra High Definition (UHD - 3840x2160) resolution. Display exceptional content in a sophisticated manner for an enhanced customer experience.

Image Rotation

Enjoy convenient content creation and management. Create your desired content on a single display and turn on Image Rotation to transform portrait orientation into horizontal and vice versa when you connect and split-screen multiple displays in a video wall matrix.

Magic Clone

Save installation time for multiple displays with Magic Clone. Simply enter your display settings the first time, save the setting information to a USB or external HDD and plug in the external device to the other sets to install them equally.

UD-A/UD-C/UD-D Compatibility

If you are replacing our previous UD-A or UD-C Series 5.5mm-bezel display models with the 3.5mm-bezel UD55D in a video wall matrix, we can provide compatible accessories including decoration stands and Multi-Information Display (MID) stands for the upgrade.
