55-inch 4K UHD commercial display

The Samsung QB55C is a 55-inch 4K UHD commercial display built for continuous operation in professional environments. It delivers a native 3840 x 2160 resolution with 350 nit brightness and a 4000:1 contrast ratio on a VA panel. The 28.5 mm ultra-slim depth allows installation in shallow spaces, while the integrated 10 W speakers provide audio without external hardware.

Suitable for signage and corporate use

This display suits retailers, corporate lobbies and control rooms that need a reliable 16:9 screen with LAN and RS-232C control for centralised management. The three HDMI 2.0 inputs and two USB 2.0 ports handle multiple source devices. Buyers who need HDR playback or a display that includes a desktop stand should consider other models.

VA panel with 4000:1 contrast

The Vertical Alignment panel produces a 4000:1 static contrast ratio, giving deeper blacks than typical IPS signage displays. Colour coverage reaches 72 % NTSC with a 2 % haze coating that reduces glare under ambient light. An 8 ms response time and 178-degree viewing angles keep content readable from wide positions.

Questions about this item

Should I pick the 55 inch model or a different size for my signage layout?

The QB55C is offered in a 55 inch diagonal with 3840 x 2160 resolution and 350 nit brightness; choose it when the viewing distance and mounting space match a 55 inch panel.

How does the 350 nit brightness look in a brightly lit retail area?

At 350 nit the display remains clearly visible under typical indoor lighting; the VA panel adds a 4000:1 contrast ratio and 178 degree viewing angles for consistent readability.

What does the HDMI 2.0 limit mean for 4K playback on this screen?

Three HDMI 2.0 ports accept 4K at 60 Hz with HDCP 2.2, so you can drive full 3840 x 2160 content without downscaling or frame-rate loss.
