Overview
NEC has discontinued the MultiSync CB651Q, a 65-inch 4K IPS collaboration display with infrared touch for up to 20 simultaneous touches and built-in wireless presentation. It suits Doha meeting rooms and classrooms, and it comes with a 3-year manufacturer warranty and 4 mm tempered anti-glare glass. Request a quote for a current or compatible replacement, or for guidance if you already own units.
What the NEC CB651Q is and who it suits
The NEC MultiSync CB651Q is a 65-inch collaboration display that combines an IPS panel, an infrared touch layer and an embedded computer for annotation and wireless sharing. NEC has discontinued this model, so this page serves organisations that already run it, buyers comparing it with newer options, and anyone seeking a replacement with the same screen size and touch capability.
Screen and touch performance for everyday meetings
The 3840 x 2160 IPS panel uses direct LED backlights, with 350 cd/m² of brightness (300 cd/m² at the shipment setting), a typical contrast ratio of 1,200:1 and 178-degree viewing angles. The 4 mm thermal-tempered front glass has an anti-glare coating, a 3 percent haze level and 88 percent light transmission, which limits reflections from windows and ceiling lights. Infrared touch supports up to 20 simultaneous points with fingers, gloves and styluses of 8 mm or more, and accuracy is specified below 2 mm.
Built-in computing, ports and expansion
The embedded computer has 2 GB of RAM and 16 GB of internal storage, along with a file manager, web browser, Mosaic Canvas whiteboard and Mosaic Connect wireless presentation. Native multi-touch is listed for Windows 7 to 11, Linux and Android. Connections include three HDMI inputs, a VGA input, a 3.5 mm audio input and output, an SPDIF digital output, LAN and RS232 control, and USB Type-B upstream and USB 2.0 downstream ports. The OPS slot follows the NEC and Intel standard and is rated for 3.5 A and 63 W.
Where it fits in Qatar
- Classrooms and training rooms: a school in Al Wakrah or a training room in Education City, where teachers annotate lessons and students share work wirelessly.
- Meeting rooms: a small team in West Bay or Msheireb reviewing documents on one screen, connecting laptops without swapping cables.
- Clinic and ministry rooms: a clinic in Al Sadd or a government office in Doha running bilingual briefings, with colleagues abroad joining over a separate conferencing system.
What to plan before you order
Without its stand, the panel measures 1,488.4 x 896.8 x 87.5 mm and weighs 39.2 kg, so check wall strength and access before delivery. It has four VESA holes at 600 x 400 mm with M8 fixings, and one standard wall mount is included. Its operating range is 0 to +40°C at 10 to 90 percent humidity, so install it in an air-conditioned room. Summer temperatures in Doha can exceed 45°C, so avoid sunrooms, outdoor areas and poorly cooled spaces. Power draw is 165 W in the eco shipment setting, under 0.5 W in power saving mode and under 2 W in networked standby. The manufacturer rates it for 12/7 operation and provides a 3-year warranty including the backlight.
Next steps
Because NEC has discontinued this model, request a quote for a current equivalent or a compatible replacement. Send your room dimensions, wall type and quantity, and the SmartRooms Qatar team will usually return a quotation within one working day. Purchase orders (LPOs), government tenders and delivery to all eight municipalities of Qatar are supported.

4 files from the manufacturerQuestions about CB651Q
Is the NEC CB651Q still sold by NEC?
No. NEC has discontinued the MultiSync CB651Q, so new orders for this exact model may not be possible. If you need the same 65-inch size and infrared touch, request a quote and SmartRooms Qatar will recommend a current equivalent or compatible replacement for your site in Doha or elsewhere in Qatar, with a specification comparison.
Is the screen sharp enough for a boardroom in Msheireb or West Bay that shows detailed spreadsheets?
Yes. The 3840 x 2160 IPS panel gives 4K detail with 178-degree viewing angles, so people seated to the side can still read spreadsheets. At 65 inches it suits small to medium rooms. Brightness is rated at 350 cd/m² maximum, or 300 cd/m² at the shipment setting, so test the room lighting before finalising the layout.
Can a ministry team in Doha annotate with several people at once?
Yes. The infrared touch supports up to 20 simultaneous touch points and responds to fingers, gloves and styluses of 8 mm or more. Accuracy is specified below 2 mm. Windows Ink and palm rejection are not supported, so teams that write often should test the pens before rollout and agree on which pen thickness they will use.
Can a training centre in Education City run sessions without bringing in a separate computer?
Partly. The embedded computer has 2 GB of RAM and 16 GB of internal storage, with a web browser, file manager, Mosaic Canvas whiteboard and Mosaic Connect for wireless presentation. That covers slides, web content and annotation. Heavier applications need an external PC or an OPS computer module, so check the software needs of each course first.
Which ports are available for laptops, control systems and audio?
The panel has three HDMI inputs, one VGA input, a 3.5 mm audio input and output, an SPDIF digital audio output, LAN 100 Mbit and RS232 control. Two USB Type-B upstream ports and six USB 2.0 downstream ports are also fitted. Map your laptops, room control and speakers to these ports before ordering.
Can I add an OPS computer module, and what does the slot supply?
Yes, the panel has an OPS slot that follows the NEC and Intel OPS standard, rated at a maximum of 3.5 A and 63 W. Listed options include an HDBaseT receiver, Intel Atom, Celeron and Core processor modules and an OPS-2C Quad 3G SDI module. Confirm that the specific module works with this model before ordering, since the source lists options but not a full compatibility table.
Will a 65-inch panel fit a classroom in Al Wakrah or a meeting room in West Bay?
It suits small to medium rooms. Without its stand the panel measures 1,488.4 mm wide, 896.8 mm high and 87.5 mm deep. Measure the wall, the viewing distance from the furthest seat and the space for the bottom bezel, which is 45.7 mm, before deciding. Classrooms with rows of students at the back may need a larger display.
Can it sit in a lobby near glass in Doha during summer?
No. It should be installed in an air-conditioned room. The operating range is 0 to +40°C with 10 to 90 percent humidity, while summer temperatures in Doha can exceed 45°C. Keep it away from direct sunlight and outdoor areas, and make sure the room cooling is running before the display is switched on.
How heavy is it and how should it be wall-mounted?
The panel weighs 39.2 kg without its stand, so it needs a sound wall and secure fixings. It has four VESA holes at 600 x 400 mm with M8 fittings. One standard wall mount is included in the box, and the manufacturer also lists a BalanceBox 400 MEDIUM wall mount as an option. Use trained installers and check the wall before mounting.
Can a school in Doha buying several units use purchase orders?
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, room sizes and mounting walls, and the team will prepare a quotation for identical units, usually within one working day, with a free site survey before installation.
What warranty and management software come with it?
The manufacturer gives a 3-year warranty that includes the backlight. NaViSet Administrator 2 is available as a free download and manages connected Sharp and legacy devices from one central location. The panel also supports a scheduler and AMX NetLinx, which helps facilities teams run displays across several rooms.
