A discontinued 75-inch interactive display

The NEC M751 IGB is a 75-inch interactive display in the MultiSync M Series, and the manufacturer has discontinued this model. This page is written for organisations that already run one and for buyers comparing it with newer touch displays. The 16:9 panel offers native 3840 x 2160 resolution, which keeps fine text and diagrams sharp when attendees sit close to the screen in a boardroom or classroom.

Touch, pen and writing performance

The screen uses InGlass touch technology rated for up to 20 simultaneous touches, with finger, glove or stylus input using a tip of at least 2 mm. Touch response is 15 ms or less and accuracy is under 1 mm. Windows Ink and palm rejection are supported, so a presenter can rest a hand on the glass while annotating. Native multi-touch is listed for Windows 7 to 11, Linux and Android.

Display, connectivity and expansion

Brightness is rated at 500 cd/m² without the protective glass, with a contrast ratio of 8,000:1 or higher, 10-bit colour depth and 72% of the DCI colour gamut. The toughened glass is 3 mm thick with an anti-glare coating. Video inputs include two DisplayPort and two HDMI connections with HDCP, plus LAN, RS232, a remote control jack and USB ports. Loop-through outputs on DisplayPort and HDMI let a connected PC pass its signal onward.

The Open Modular Intelligence slot accepts a Raspberry Pi Compute Module 4 or an Intel Smart Display Module of up to 66 W, so computing can sit inside the display instead of in a separate box. The model is Crestron Connected certified and tested compatible with Barco ClickShare (Conference), which suits rooms managed by a central control system.

Where it fits in Qatar

Government meeting rooms: a ministry team in Msheireb or West Bay joining cross-border calls with colleagues abroad, with the screen controlled from a room panel over LAN or RS232.
Schools and training centres: a private school in Al Wakrah or a training centre in Education City, where split-screen layouts show two sources side by side during bilingual lessons.
Corporate offices: a workshop room in an energy company office in the Industrial Area, where staff annotate shared documents with pens.

Qatar summers call for care. The rated operating range is 0 to +35 °C, so the display belongs in an air-conditioned room, away from windows that take direct sun. The housing is rated IP5x at the front and IP2x at the back, which points to indoor use.

Planning the installation

The unit weighs 62 kg and measures 1,724.6 x 1,003 x 93.4 mm, with a 21.9 mm symmetrical bezel. The VESA pattern is 600 x 400 with M8 fixings, and a wall mount (L20PNWALL90EU) and trolley options are listed. Because of its size and weight, SmartRooms Qatar recommends a free site survey before wall-mounting to check the wall structure, lifting access and cable routes. The internal power supply runs on 100-240 V AC at 50/60 Hz.

The unit carries a 3-year warranty that includes the backlight, with an optional fourth and fifth year extension. A one-year FlatFrog Board for Rooms licence is included free of charge.

Because this model is discontinued, the most useful next step is a quote for a current equivalent or a compatible replacement. Send the room size, mounting method and connection list, and the SmartRooms Qatar team will prepare a quotation, usually within one working day, covering delivery to all eight municipalities of Qatar.

Questions about M751 IGB

Is the NEC M751 IGB still sold by NEC?

No. NEC has discontinued the M751 IGB. If you are buying for a new room, request a quote for a current equivalent or compatible replacement. If you already run one, SmartRooms Qatar can check the listed accessories, such as the L20PNWALL90EU wall mount and trolley options, against your replacement plan. Compatibility is confirmed within the quotation.

Is a 75-inch panel right for a boardroom in Msheireb or West Bay?

It suits boardrooms and meeting rooms where attendees sit at a distance and need clear text. The panel offers 3840 x 2160 resolution and 500 cd/m² brightness without glass. Before buying, measure the distance from the seats to the wall and confirm the mounting position, because a 62 kg panel is a significant fixing load.

How many touch points does it support, and which tools work?

The InGlass touch layer supports up to 20 simultaneous touches with a finger, a glove or a stylus with a tip of at least 2 mm. Two passive styluses are included. Touch accuracy is under 1 mm with response of 15 ms or less. Windows Ink and palm rejection are supported, which matters for teachers and presenters who annotate directly on the screen.

How can we add computing to the display for a lecture room in Lusail?

The Open Modular Intelligence slot accepts a Raspberry Pi Compute Module 4 or an Intel Smart Display Module, with the Intel module listed in Large and Small forms up to 66 W. Choose the module that matches the software your lecture room needs. The quotation will confirm which option fits your build and the module is supplied as part of your configuration.

Will it cope with a Doha summer in a reception area?

The operating range is 0 to +35 °C with humidity of 20 to 80%. Qatar summer temperatures rise above 45 °C, so the room must be fully air-conditioned, and the display should sit away from windows that receive direct sun. Confirm the room cooling capacity before installation, and check that the lobby is not exposed to direct sunlight or dust.

What connections are available for laptops and video systems?

Inputs include two DisplayPort and two HDMI connections, both with HDCP, plus USB 2.0 ports and a LAN port. The DisplayPort and HDMI outputs loop the signal through to another device, and a 3.5 mm audio output jack is provided. Control connections include RS232 and a remote control jack, and the panel also offers a 100Mbit LAN control output.

Can a training centre in Education City link it to a Crestron-controlled room?

Yes, the data lists Crestron Connected certification. The model is also tested compatible with Barco ClickShare (Conference). External control options include AMX NetLinx, PJLink, SNMP, an HTTP browser and ASCII commands. Confirm your specific control processor and version with SmartRooms Qatar before ordering so the integration is planned correctly.

How heavy is it, and what is needed to mount it on a school wall?

The panel weighs 62 kg and measures 1,724.6 x 1,003 x 93.4 mm, with VESA 600 x 400 mounting holes and M8 fixings. A wall mount (L20PNWALL90EU) is listed as an option. Plan for more than one person to lift it, and book a free site survey to check the wall structure before fixing the mount, especially in a school hall in Al Khor.

Does the power supply suit an installation in Qatar?

The internal power supply is rated 100-240 V AC at 50/60 Hz, a range that includes the 240 V, 50 Hz mains used in Qatar. Power savings mode draws less than 0.5 W, and networked standby draws less than 2 W. Ask your electrician to confirm socket positions and circuit capacity before delivery, and check the cable routes during the site survey.

What warranty applies, and can it be extended?

The manufacturer lists a 3-year warranty that includes the backlight, with an optional fourth and fifth year extension. Products are covered by the manufacturer's warranty. A one-year FlatFrog Board for Rooms licence is included free of charge. Ask for the extension option when you request your quotation so it is priced alongside the unit.

Can a school in Al Wakrah order several units on an LPO?

Yes. SmartRooms Qatar accepts purchase orders (LPOs), government tenders including Monaqasat, and payment by bank transfer, cheque or purchase order. Send the number of rooms and their sizes with your request. Quotations usually arrive within one working day, and delivery covers all eight municipalities of Qatar. Because the model is discontinued, the quote will name a current equivalent.
