Product Overview

Overview

Samsung QB55B is a slim, professional 55 inch 4K UHD signage display built for mall corridors and office reception areas. Its ultra-thin 28.5mm chassis and symmetrical bezel deliver a clean, boardroom-ready look, while native Cisco Webex Room Kit certification makes it a strong fit for unified communications spaces.

Key specifications of the QB55B include a 55-inch 4K UHD panel, 350 nits brightness, 16/7 rated operation, Tizen 6.5 built in and 200 x 200 mm VESA mounting. Corporate AV supplies and integrates the QB55B across India for retail, corporate and public-facing digital signage projects, including site survey, mounting and commissioning where the project needs it.

Key features

  • 55 inch Direct-Lit LED (D-LED) 4K UHD panel, 350 nits brightness, 4000:1 contrast, Dynamic Crystal Color
  • Ultra-slim 28.5mm chassis with symmetrical 11.5mm bezel for landscape or portrait orientation
  • Quantum Processor 4K SoC running Tizen 6.5, 16GB onboard storage for standalone playback
  • Natively certified for Cisco Webex Room Kits, plus Microsoft Teams Rooms and Zoom Rooms compatible
  • Crestron Connected, Extron IP Link, and AMX compatible for automated boardroom control
Why choose the QB55B
Choose the QB55B when a 55-inch 4K UHD screen has to run reliably in a public or customer-facing space, with 16/7 rated operation. At 350 nits, it is aimed at controlled indoor lighting such as meeting rooms and reception areas. Corporate AV checks the mounting surface, power and signal routing during a site survey, so the QB55B is installed and commissioned as part of a complete AV system, not just delivered as a box.

Frequently Asked Questions

Is the Samsung QB55B rated for 24/7 operation?
The QB55B is specified for 16/7 operation (16 hours a day, 7 days a week), not 24/7. If your screens must run around the clock, choose a 24/7-rated model from the Samsung range.
Does the Samsung QB55B need an external media player or PC?
The QB55B has a built-in Tizen 6.5 platform, so basic content playback does not need a separate PC. For larger screen networks or advanced scheduling, Corporate AV can specify the content-management or media-player setup as part of the design.
Which inputs and control ports does the Samsung QB55B have?
Samsung lists the following for the QB55B: 3x HDMI 2.0 (HDCP 2.2), 1x DisplayPort 1.2; 2x USB 2.0 media ports, RJ-45 Ethernet, RS-232C control in/out.
How bright is the Samsung QB55B and where does it work best?
Samsung rates the QB55B at 350 nits. That level is aimed at controlled indoor lighting such as meeting rooms and reception areas.
What mounting pattern does the Samsung QB55B use?
The QB55B uses a 200 x 200 mm VESA pattern and supports both landscape and portrait installation. Corporate AV can supply a matching wall mount, stand or bracket and check the wall can carry the load.
Does Corporate AV install the Samsung QB55B?
Yes. Corporate AV can supply the QB55B only, or deliver it turnkey with site survey, mounting, cabling and commissioning. See our AV installation services for how a project is run.
