NEC 55-inch Du-Co Room System (Discontinued)

Name: NEC 55-inch Du-Co Room System Dual-Display Collaboration System
Brand: NEC
SKU: nec-55-inch-du-co-room-system
Availability: Discontinued

Overview

The NEC 55-inch Du-Co Room System is a discontinued dual-display collaboration setup: one InGlass touch panel and one matching non-touch panel, each with 3840 x 2160 resolution and 500 cd/m² brightness. Touch supports up to 20 simultaneous touches, pen input and Windows Ink, while 18.4 mm bezels suit boardrooms and hybrid meeting rooms in Doha. Because NEC has discontinued this model, organisations weighing it against newer options should request a quote for a current equivalent.

A dual-display system built for hybrid meetings

The NEC 55-inch Du-Co Room System pairs two 55-inch 16:9 panels with identical design: one interactive display with InGlass touch and one non-touch display. Both use IPS panels with edge LED backlights, a 3840 x 2160 native resolution and 500 cd/m² brightness. NEC has discontinued this model, so this page is written for organisations that already run it, buyers comparing it with newer options and anyone looking for a replacement.

Touch and writing performance for working meetings

The interactive panel supports up to 20 simultaneous touches with a response time of 15 ms or less and an accuracy below 1 mm. Finger, gloved hand and stylus input (2 mm or larger) all work, and palm rejection and Windows Ink support handwriting during discussions. The glass is 3.0 mm premium toughened glass with an anti-glare coating, a 7H hardness rating and 89% light transmission according to the datasheet.

Ports, control and computing options

Video arrives through one DisplayPort and two HDMI inputs, all with HDCP. Control runs over a 100Mbit LAN connection, RS232 and a 3.5 mm remote jack, and a USB 2.0 port plays media files directly from storage. The system supports AMX NetLinx, Crestron Connected, PJLink, SNMP and HDMI CEC, and NEC NaViSet Administrator 2 handles remote management and email alerts. Each display has an Open Modular Intelligence slot that accepts a Raspberry Pi Compute Module 4 or an Intel Smart Display Module rated up to 66 W.

Where it fits across Qatar

Boardrooms in West Bay or Msheireb: a leadership team holds a hybrid meeting with colleagues in Doha and abroad, using the touch panel for live annotation while the non-touch panel shows shared documents.
University rooms in Education City: a research group reviews data on screen during a video-linked session with partners overseas, using the 55-inch size for a small seminar room.
Government meeting rooms in Doha: a ministry team reviews a bilingual document during a meeting, with the interactive panel used for drafting and the second screen used for reference material.

Planning the room, power and heat

Each display measures 1,284.5 x 757.3 x 70.9 mm and weighs between 38 and 38.5 kg, so two panels add up to roughly 76 to 77 kg on the wall. The rear mounting pattern is 300 x 300 mm VESA with four M6 holes, and the bezel is 18.4 mm on every side. A free site survey lets SmartRooms Qatar check wall structure before installation. The operating range is 0 to +35 °C and 20 to 80% humidity, so rooms must be properly air-conditioned when summer temperatures in Qatar pass 45 °C. Power input is 100 to 240 V AC at 50/60 Hz, and power draw is 110 W maximum in eco mode. The manufacturer lists a three-year warranty that includes the backlight.

Because this model is discontinued, the best next step is to request a quote for a current equivalent or a compatible replacement. Share your room size, the number of participants and whether you need one interactive panel or two, and the SmartRooms Qatar team will respond with a quotation usually within one working day.

Questions about 55-inch Du-Co Room System

Is the NEC 55-inch Du-Co Room System still sold by NEC?

No. NEC has discontinued the 55-inch Du-Co Room System, so it is no longer in the manufacturer's current range. If you need a dual-display collaboration setup with similar specifications, or a compatible replacement for an existing unit, request a quote. The SmartRooms Qatar team will suggest a current equivalent that matches your room size and mounting arrangement.

Who is this dual-display system suited to in Qatar?

It suits boardrooms, executive meeting rooms and hybrid collaboration rooms where people write on screen while remote colleagues join. A company in West Bay could use the interactive panel for shared whiteboarding while the matching non-touch panel displays material for the whole room. The 55-inch size suits small and mid-sized groups rather than lecture halls, so confirm your room dimensions before requesting a quote.

How does the touch layer perform for writing and annotation?

The interactive panel supports up to 20 simultaneous touches, with a response time of 15 ms or less and an accuracy below 1 mm. It accepts finger, gloved hand and stylus input of 2 mm or larger. Palm rejection and Windows Ink support natural handwriting, which helps presenters annotate slides during a meeting without interrupting the discussion.

Does it work with Microsoft Teams and Zoom?

The manufacturer states the system is optimised for video conferencing room systems, including Microsoft Teams and Zoom. In a meeting that links a team in Doha with colleagues abroad, the conferencing device or PC connects to the DisplayPort or HDMI inputs, while the touch panel is used for annotation. Confirm your conferencing device's video output type with the SmartRooms Qatar team before the quotation is finalised.

What ports and inputs does the system provide?

Video inputs are one DisplayPort with HDCP and two HDMI inputs with HDCP. Control options include a 100Mbit LAN port, RS232 and a 3.5 mm remote jack. There is also a USB 2.0 port for media playback, a 3.5 mm audio output and a powered USB port rated at 10 W. This covers a conferencing device, a laptop and a control system in the same room.

Can the displays be controlled and managed remotely?

Yes. The data lists support for AMX NetLinx, Crestron Connected, PJLink, SNMP, HDMI CEC and an HTTP browser, plus NEC NaViSet Administrator 2 for remote management and automated email alerts. Hardware buttons and infrared control can be disabled, which suits schools and government offices that need fixed settings. Ask for a quote that confirms which control system your room uses.

What does the optional computing slot accept?

Each display has an Open Modular Intelligence slot. It accepts a Raspberry Pi Compute Module 4 or an Intel Smart Display Module, with the Intel modules rated for up to 66 W and available in large and small sizes. The slot lets you run applications from the display itself without a separate computer. Your quotation will state whether a module is included in the order.

How should I plan wall mounting for a boardroom?

Each display measures 1,284.5 x 757.3 mm and 70.9 mm deep, and weighs between 38 and 38.5 kg. It mounts to a 300 x 300 mm VESA pattern with four M6 holes, and a dedicated mounting option is listed as an accessory. Two panels together weigh roughly 76 to 77 kg, so SmartRooms Qatar offers a free site survey to check wall structure before installation.

Can it be installed in a room that gets very hot?

The operating range is 0 to +35 °C with 20 to 80% humidity, and storage is rated from -20 to 60 °C. Qatar summer temperatures can exceed 45 °C, so the room must be air-conditioned to hold conditions within the operating range. If the room has a window facing the sun or a door to an outdoor area, confirm the environment with the SmartRooms Qatar team before ordering.

Does it run on Qatar's 240 V mains supply?

The internal power supply accepts 100 to 240 V AC at 50/60 Hz, which covers the 240 V supply used in Qatar. Power draw is 110 W maximum in eco mode and below 0.5 W in standby, or below 2 W with networked standby. The shipping content includes a power cable, but confirm the plug fitting with the SmartRooms Qatar team before installation.

What warranty comes with this product?

The manufacturer's data lists a three-year warranty that includes the backlight, and the product is covered by that warranty. The display is rated for 24/7 operation, and the manufacturer describes additional services separately. Ask SmartRooms Qatar for the written warranty terms with your quotation, as the full conditions are not part of the product data.

Can a school or government body buy several units on a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs), government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. A school in Al Wakrah fitting out several meeting rooms can issue one LPO for the whole project. Because this model is discontinued, the quotation will be based on a current equivalent or compatible replacement.
