Request a quote and we will advise on the closest option.

What this discontinued 84-inch display offers

NEC has discontinued this 84-inch UHD touch display, so it is no longer in the manufacturer's current range. It belongs to the InfinityBoard family and uses an 84-inch S-IPS panel with a 3840 x 2160 native resolution, an InGlass touch layer and an integrated OPS Slot-In PC. This page is written for organisations that already own the model, for buyers comparing it with newer boards, and for anyone who needs a replacement that behaves in a similar way.

Contrast: 1,400:1 typical, with 178-degree horizontal and vertical viewing angles.
Touch: up to 20 touch points, operated by finger, gloves or a stylus of 2 mm or more, with a response time of 15 ms or less.

Built-in video conferencing and collaboration

The package includes a Huddly camera with a 16-megapixel sensor that outputs 720p at 30 fps, with 3x digital zoom and driverless plug-and-play setup. External SP-841SM speakers rated 40 W + 40 W are supplied alongside the integrated 10 W + 10 W speakers. Mosaic Hub links teams in different locations and includes one year of free subscription, while Mosaic Canvas lets several people annotate the display at the same time. Two passive pens and an NEC MultiPresenter Stick complete the bundle.

Where it fits in Qatar

A boardroom in West Bay or The Pearl, where directors join from abroad and review shared documents on the panel.
A seminar room in Education City or a training centre in Al Sadd, where a lecturer writes on the screen and presents to a small group.
A meeting room in a government office in Msheireb, used for presentations and reviews in a conditioned room where Arabic and English documents are discussed side by side.

Planning the installation

At 97 kg and 2,179 x 1,151 x 90 mm, this panel needs a wall or frame rated for its load, and two people should handle the lift. It mounts on a 400 x 400 mm VESA pattern with four M8 holes, and the bezel is 22 mm wide. Summer temperatures outside in Doha can exceed 45 °C, so keep the panel in an air-conditioned room that stays within its 0 to +35 °C operating range. A free site survey lets our team check wall construction and access routes before installation.

Two height-adjustment options are relevant. The BalanceBox 650 mounting adapter (order code 100014705) adjusts up to 650 mm with light hand pressure and needs no electricity. The PD03MHA motorised trolley (order code 100014281) suits 65-inch and 84-inch panels and adjusts up to 500 mm.

Because this model is discontinued, request a quote from SmartRooms Qatar with your room size, the devices you connect, and your wall type. We will recommend a current equivalent or a compatible replacement. Quotations are usually provided within one working day.

Questions about 84-inch UHD Touch Display

Is the NEC 84-inch InfinityBoard still sold by NEC?

No. NEC has discontinued this 84-inch UHD touch display, so it is no longer in the manufacturer's current range. SmartRooms Qatar can quote a current equivalent or a compatible replacement that matches your room size, touch requirements and connectivity. Send us the room details and the devices you use, and our team will identify the closest option for your meeting space.

We already have one in a West Bay boardroom. What should we check before keeping it in service?

Start with your purchase date and warranty paperwork. The source data lists a 3-year warranty including the backlight, with optional fourth and fifth year extensions. Next, confirm the room stays within the 0 to +35 °C operating range and 20 to 80 percent humidity. If the room cannot hold those conditions, the panel should not run there in summer.

What screen size and resolution does it offer?

It is an 84-inch (213.5 cm) display with a native resolution of 3840 x 2160 at 60 Hz, which is 4K UHD. The active screen area measures 1,860 x 1,046 mm. The panel uses S-IPS technology with edge LED backlights and an anti-glare toughened glass front. The 84-inch size suits larger rooms where people sit further back, such as lecture rooms and boardrooms.

Does it include a computer, and what are its specifications?

The source data lists an OPS Slot-In PC in the scope of supply. It has an Intel Core i7 vPro-6820EQ processor, 8 GB DDR4 memory, a 128 GB SSD and Windows 10 IoT Enterprise, with a LAN port and a mini DisplayPort output. The slot follows the Open Pluggable Specification, which allows future performance upgrades. Please confirm the exact configuration in your quotation.

How does the touch function work, and can it be used with gloves?

The InGlass touch layer supports up to 20 simultaneous touch points and responds to finger, gloves and a stylus of 2 mm or more. Response time is 15 ms or less, and touch accuracy is under 1 mm. Two passive pens with a 2 mm smart tip are included. The data also lists palm erasing, so the pen and palm can be used together while writing.

Which ports does it have for laptops and room control?

Video inputs are one DisplayPort, two DVI-D and four HDMI, all with HDCP. Audio inputs include a 3.5 mm analogue jack and digital audio over HDMI or DisplayPort. For control it offers 100Mbit LAN with SNMP, RS-232 and IR. The listed connectors do not include USB-C, so check the laptops and room PCs you plan to connect before ordering.

Can it host video calls with teams in Doha and abroad at the same time?

It is built for that use. The Huddly camera has a 16-megapixel sensor, outputs 720p at 30 fps, offers 3x digital zoom and has a 152-degree diagonal viewing angle. The external 40 W + 40 W speakers help sound reach the back of the room. Mosaic Hub connects teams in different locations and includes one year of free subscription. Confirm which video platform your organisation uses before buying.

Does the software support Arabic menus and Arabic text input?

The source data does not list language support for the on-screen menus, the Mosaic apps or the Windows 10 IoT environment, so we cannot confirm it here. If your meeting room works in Arabic and English side by side, ask the SmartRooms Qatar team to check the language options of the bundled software before you request a quote. We will state the answer in the quotation.

Will it work in a Doha meeting room during summer without a dedicated cooling plan?

The stated operating range is 0 to +35 °C with 20 to 80 percent humidity. Outdoor temperatures in Doha during summer can exceed 45 °C, so the panel should sit in an air-conditioned room that stays within that range. Avoid lobbies with unshaded glass walls and open-air kiosks. Our team can review the room layout during the free site survey.

How heavy is it, and what does the wall need to carry?

The 84-inch display weighs 97 kg and measures 2,179 x 1,151 x 90 mm, so the wall or frame must be rated for that load, and two people should handle the lift. The VESA pattern is 400 x 400 mm with four M8 holes. In older school buildings in Al Rayyan or Al Khor, a free site survey before mounting shows the wall construction and the access route.

Which mounting and height-adjustment options are available?

The BalanceBox 650 height-adjustable mounting adapter (order code 100014705) allows up to 650 mm of adjustment, moves with light hand pressure, needs no electricity and mounts directly on the wall. For mobility, the PD03MHA motorised trolley (order code 100014281) covers 65-inch and 84-inch models with up to 500 mm of height adjustment and integrated cable management. Compatibility is confirmed when the quotation is prepared.

Can a government ministry or school buy it through a tender or LPO?

Yes. SmartRooms Qatar supplies government tenders, including Monaqasat, and accepts purchase orders (LPOs). Payment can be made by bank transfer, cheque or purchase order. Because NEC has discontinued this model, the tender specification should name a current equivalent or compatible replacement, and the quotation will be prepared against that specification. Products are covered by the manufacturer's warranty.
