What the QB49N is and where it fits

The Samsung QB49N is a 49-inch display from the QBN Series, designed for digital signage rather than meeting-room presentations. Its 3,840 x 2,160 UHD panel uses a New Edge panel type with a 60Hz refresh rate and a non-glossy frame, so it can show menus, wayfinding, schedules and promotional loops in public-facing spaces.

Picture, brightness and viewing angle

The panel is rated at 350 typical brightness and a 4,700:1 contrast ratio, with 178/178 horizontal and vertical viewing angles. An 8ms typical response time and a 72% colour gamut suit moving content and branded graphics. Dynamic contrast is set to Mega, and Intelligent Picture Quality works to bring lower-resolution sources closer to UHD-level detail, which helps when older promotional files play alongside newer ones.

Connectivity, software and control

The QB49N offers two HDMI inputs and one DVI input, two USB ports, an IR input, audio input, a stereo mini jack audio output, RS232 in and out, and RJ45 input, plus built-in WiFi. It has no DisplayPort, HDBaseT or RJ45 output, so plan source devices and cabling around the HDMI and DVI inputs.

MagicINFO S6 is embedded and runs on TIZEN OS, so the screen can play scheduled content from its own software. Samsung KNOX provides three-layer protection and controls USB and network exchange through signage device management. Administrators can monitor and diagnose irregularities from any location.

Qatar scenarios

A bank branch in West Bay might place the screen in its queue area to show service updates and product information. A university in Education City could mount a unit beside a student services desk to display timetables and events. In a hotel or mall lobby in Doha, the 49-inch size suits a wall or stand position where visitors read it from a few metres away.

The operating range is 0°C to 40°C with 10% to 80% humidity. Qatar summer temperatures can exceed 45°C, so keep the QB49N in air-conditioned indoor spaces and avoid sun-facing windows or outdoor positions. The IP5x-validated design tolerates a degree of dust, which helps near entrances, but operation is not guaranteed with certain dust types such as metal dust.

Planning the installation

Confirm the 200 x 200 mm VESA pattern and wall structure for a 13.3 kg set.
Allow for set dimensions of 1,102.8 x 637.8 x 59.4 mm and packaging of 1,250 x 778 x 153 mm.
Power is rated AC100-240V, 50/60Hz, with 132 W in on mode and 0.5 W in sleep mode.
Optional WMN4070SE wall mount and STN-L4955H stand are available.

Questions about QB49N

What is the Samsung QB49N designed for?

The QB49N is a 49-inch UHD 4K display built for digital signage, meaning menus, wayfinding, schedules and promotional content in public-facing spaces. Its 3,840 x 2,160 panel and 350 typical brightness suit lobbies and corridors where people pass by and glance at information. Its specification does not list a camera or conferencing features, so it is a signage product rather than a meeting-room display.

Can I run content on the QB49N without an external media player?

Yes. The embedded MagicINFO S6 software runs on TIZEN OS inside the display, so you can schedule and play content from the screen itself. This suits a single screen in a reception area or a school corridor where a separate media box would add cabling and another device to maintain. Ask our team to confirm the content workflow that fits your site.

Does the QB49N work with 240V power in Qatar?

The power supply is rated AC100-240V at 50/60Hz, so the stated range covers Qatar's 240V, 50Hz mains. The display draws 132 W in on mode and 0.5 W in sleep mode. The data does not specify a plug type, so ask SmartRooms Qatar which plug or adaptor your installer needs before ordering several units for a school or office.

Can the QB49N be used outdoors or next to a sunny window in Doha?

We do not recommend outdoor or sun-facing positions. The QB49N is rated for 0°C to 40°C and 10% to 80% humidity, while Qatar summer temperatures can exceed 45°C. Its IP5x-validated design tolerates some dust, but operation is not guaranteed with certain dust such as metal dust. Keep it in an air-conditioned indoor space and confirm the location with our team.

How large is the QB49N and how heavy is it?

The set measures 1,102.8 x 637.8 x 59.4 mm and weighs 13.3 kg. The package measures 1,250 x 778 x 153 mm and weighs 17.9 kg. Plan for two people to lift the unit onto a wall, and check that the wall can carry the set weight plus the mount before installation day.

Which wall mount or stand is available for the QB49N?

The optional WMN4070SE mount and STN-L4955H stand are listed for this model. The set has a 200 x 200 mm VESA mount pattern, so confirm that the chosen bracket matches it. A free site survey helps SmartRooms Qatar check wall structure, cable routing and viewing height in a lobby or corridor before the mount is ordered.

How does the QB49N handle security on a shared network?

Samsung KNOX provides three-layer protection and controls USB and network exchange through signage device management. The display offers RJ45 input and built-in WiFi, so IT teams should review network settings before connection. Government offices and banks should share their network policy with us so the quotation reflects how the screen will connect.

Can the QB49N be controlled remotely or by a control system?

Yes. RS232 in and out, RJ45 input and an IR input support control integration, and remote monitoring lets administrators monitor and diagnose irregularities from any location. The data does not list daisy-chain video wall support for MagicINFO, so a multi-screen video wall project should be quoted against a model that supports that function.

Which ports does the QB49N have?

The QB49N has two HDMI inputs, one DVI input, two USB ports, an IR input, an audio input, a stereo mini jack audio output, RS232 in and out, RJ45 input and built-in WiFi. It has no DisplayPort, HDBaseT, video output or RJ45 output. Check the laptop or media player you plan to connect so you have the correct HDMI or DVI cable.

Is the QB49N suitable for a school or university corridor in Qatar?

It suits corridor noticeboards, library entrances and admissions areas where students read announcements and timetables from a short distance. A school fitting out several corridors can order multiple units under one purchase order. The 49-inch size and non-glossy frame work well in these spaces, and we can confirm mount options and quantities in the quotation.

How readable is the QB49N for menus and text?

The 3,840 x 2,160 UHD panel, 4,700:1 contrast ratio, 178/178 viewing angles and 72% colour gamut keep text and graphics clear. Intelligent Picture Quality optimises on-screen text with crisp edges and fine detail. This makes the QB49N a practical choice for restaurant menus, bank service information and wayfinding boards in busy Doha malls.

How do I request a quote for the QB49N and what happens next?

Request a quote with the quantity, mount type and installation address in Qatar. Quotations are usually issued within one working day. SmartRooms Qatar accepts purchase orders, including LPOs and government tenders through Monaqasat, and payment by bank transfer, cheque or purchase order. A free site survey can be arranged before installation.
