What the NEC X551UHD IGB is

The NEC MultiSync X551UHD IGB is a 55-inch LCD interactive display with a 3840 x 2160 panel, edge LED backlighting and an InGlass touch layer built into the front glass. The manufacturer has discontinued this model, so this page is written for organisations that already run it, buyers comparing it with newer options, and anyone who needs a replacement. Request a quote for a current equivalent or a compatible replacement from SmartRooms Qatar.

Display and touch facts that matter

The active screen area measures 1,209 x 680 mm, and the 3 mm premium toughened front glass has an anti-glare coating with 88 percent light transmission. Brightness is 500 cd/m², with a 300 cd/m² Eco setting that is active when shipped, and typical contrast is 4000:1. The 178-degree viewing angles keep content readable from the side of a room.

Touch works with fingers, gloves and styluses with a tip of at least 2 mm. Up to 20 touches are supported with a stated accuracy below 1 mm, and palm rejection and Windows Ink are listed among its touch features. Two styluses are included, so a teacher or presenter can share the pen without waiting.

Connectivity and expansion

Video inputs: 1 DisplayPort, 2 DVI-D and 4 HDMI, with HDCP on the digital inputs.
Resolution: native 3840 x 2160 at 60 Hz over DisplayPort, with other signals automatically upscaled to UHD.
Audio and control: 3.5 mm audio input, HDMI and DisplayPort audio, LAN with SNMP, RS232 and remote control.
USB and OPS: four USB 3.0 hub ports and an OPS slot for a slot-in PC using the NEC and Intel OPS standard.

Where it fits in Qatar

In a classroom in Al Wakrah or a training room at Education City, a 55-inch panel suits a small to medium room where one presenter writes and annotates on a single screen. In a West Bay meeting room, a 4K signal from a laptop shows spreadsheets and drawings with fine detail. In a government office lobby, the display can carry information only where the room stays air-conditioned, because its operating range is 0 to +35 °C.

What to plan before ordering

Room temperature: keep the display within 0 to +35 °C and 20 to 80 percent humidity. Outdoor temperatures in Qatar regularly exceed 45 °C in summer.
Mounting: VESA 400 x 400 mm with four M8 holes. Without stand it weighs 40.5 kg and measures 1,284.5 x 757.3 x 80.3 mm. A wall mount (PDW S 32-55 PL) and a trolley (PDMHM-L) are listed as options.
Protection: IP40 at the front and IP20 at the back, so keep it away from dusty areas.
Power and energy: 162 W in the Eco shipment setting, 219 kWh annual use based on four operating hours per day, energy class B.
Warranty: 3 years including the backlight, with optional fourth and fifth year extensions.

Questions about X551UHD IGB

Has NEC discontinued the X551UHD IGB?

Yes. NEC has discontinued this 55-inch MultiSync model. If your organisation is planning a new purchase, SmartRooms Qatar can prepare a quote for a current equivalent that matches your required size, resolution and touch specification. Quotations are usually issued within one working day, so send us your room details and intended use to get started.

Who is this 55-inch display suited to in Qatar?

It suits small and medium rooms in Doha, Lusail or Al Sadd where one presenter writes and annotates on a single screen, such as classrooms, training rooms and meeting rooms. Larger lecture halls and boardrooms often need a bigger panel. The 3840 x 2160 resolution and 4000:1 typical contrast help document-heavy presentations stay sharp when viewed from the back of a room.

What touch features does the X551UHD IGB offer?

The InGlass touch layer supports up to 20 simultaneous touches and responds to fingers, gloves and styluses with a tip of at least 2 mm. The data lists accuracy below 1 mm and a touch response of 15 ms or less. Native multi-touch works with Windows 7 to 11, Linux and Android, while Windows XP, Vista and Mac OS use default mouse mode. Two styluses come in the box.

Which ports does it have for laptops and other sources?

It has one DisplayPort input with HDCP, two DVI-D inputs with HDCP and four HDMI inputs with HDCP. Audio can enter through a 3.5 mm jack, HDMI or DisplayPort. Four USB 3.0 hub ports, a LAN 100Mbit port and an RS232 port complete the connectivity. Check the output of your laptop, media player or PC before ordering so you know which cables you need.

Does it support 4K, and which resolutions are native?

The native resolution is 3840 x 2160 at 60 Hz, and DisplayPort supports that full 4K signal at 60 Hz. HDMI supports 3840 x 2160 at 24 and 30 Hz, plus 25 Hz. Lower signals such as 1920 x 1080 and 720p are accepted, and other signals are automatically upscaled to UHD. For a laptop that outputs 4K at 60 Hz, use the DisplayPort input.

What brightness and contrast does the panel deliver?

The panel is rated at 500 cd/m² in its standard setting and 300 cd/m² in Eco mode, which is the shipment setting. Typical contrast is 4000:1, with 178-degree horizontal and vertical viewing angles at a 10:1 contrast ratio. Grey-to-grey response time is 6 ms. The 3 mm toughened front glass has an anti-glare coating with 88 percent light transmission and a haze level of 25 percent.

Can it be installed in an unconditioned lobby or outdoors in Qatar?

No. The operating temperature range is 0 to +35 °C with 20 to 80 percent humidity, and the IP40 rating applies to the front only. Summer temperatures in Qatar regularly pass 45 °C, so place it inside an air-conditioned room, away from windows that receive direct sun and from dust-prone entrances. Confirm room conditions with the SmartRooms Qatar team before ordering.

Can I wall-mount it in a Doha office, and what should I plan?

It supports VESA 400 x 400 mm mounting with four M8 holes, and a wall mount (PDW S 32-55 PL) is listed as an option. Without stand it weighs 40.5 kg and measures 1,284.5 x 757.3 x 80.3 mm, so check that the wall and fixings can carry that load. SmartRooms Qatar offers a free site survey before wall-mounting a panel of this size, followed by professional installation.

Is a trolley available for a classroom that moves the screen between rooms?

The product data lists a trolley, model PDMHM-L, as an available accessory, so the display can move between rooms without being fixed to a wall. The panel weighs 40.5 kg without stand, so plan for a sturdy trolley and a two-person move. Tell us which rooms are involved and we will include the accessory in your quotation.

Does it have built-in speakers and sensors for a training room?

Integrated speakers are rated at 10 W plus 10 W, and optional external speakers at 15 W plus 15 W are listed. For a small training room at Education City, the built-in pair may suffice for a presenter and a small group, while a larger room would justify the external option. The panel has three integrated temperature sensors with programmable triggered actions, and an optional external human sensor with a 4 to 5 m range is available.

What should a facilities team in Al Rayyan know when ordering several units?

The stated warranty is 3 years including the backlight, with optional fourth and fifth year extensions you can ask about in your quotation. Annual energy consumption is 219 kWh based on four operating hours per day, in energy class B. Schools and government units can order several panels under a single purchase order (LPO), and SmartRooms Qatar handles delivery to all 8 municipalities.

What should I buy if this model is no longer available?

Request a quote for a current 55-inch interactive display or a compatible replacement. Compare native 4K resolution at 60 Hz, touch point count, OPS slot availability, input types and quantities, and operating temperature range against this model. Send us your room size, operating environment and software platform, and we will prepare a quotation matched to them.
