Name: NEC X981UHD-2 SST 98-inch ShadowSense Interactive Touch Display
Brand: NEC
SKU: nec-x981uhd-2-sst
Availability: Discontinued

Overview

The NEC X981UHD-2 SST is a 98-inch 4K interactive touch display with ShadowSense overlay touch tracking up to 12 points, a 500 cd/m² panel and an OPS slot for an optional Windows PC inside the display. NEC has discontinued this model, so it suits organisations already running it or comparing options before buying. Qatar schools, ministries and meeting rooms needing a large collaborative screen should request a quote for a current equivalent.

What this 98-inch touch display is

The NEC X981UHD-2 SST is a 98-inch (248 cm) interactive display from the MultiSync X Series, built around a 4K panel and an overlay touch system called ShadowSense. Its active screen measures 2,159 x 1,214 mm, giving a room-filling writing surface for teams that annotate, rearrange and compare content together. NEC has discontinued this model. This page is written for organisations that already run one, buyers comparing it with newer models, and anyone looking for a replacement.

Touch performance for shared working

12 touch points tracked at once, with accuracy below 2 mm.
Finger, glove and stylus input, with styluses of 4 mm or more supported.
Windows Ink recognises pen writing, erasing and touch gestures inside MS Office applications.
USB 2.0 connection that needs no driver installed on the host PC.

Native multi-touch covers Windows 7 to 11, Linux and Android, and mouse emulation covers Windows XP, Vista and Mac OS. The 5 mm toughened glass has a single-sided anti-reflective coating and transmits 92% of light (plus or minus 2%).

Picture quality and connections

The S-IPS panel with direct LED backlighting delivers a native resolution of 3840 x 2160 at 60 Hz, 500 cd/m² in the shipment setting (300 cd/m² in Eco mode), a typical contrast ratio of 1300:1 and an 8 ms grey-to-grey response. Connections include one DisplayPort input, four HDMI inputs and two DVI-D inputs, all with HDCP, plus a 3.5 mm audio jack, 100 Mbit LAN, RS-232 and an IR remote sensor. The OPS slot accepts an optional Windows-based Slot-in-PC, so a computer can sit inside the display rather than on a trolley beside it.

Where it fits in Qatar

A university seminar room in Education City could use the 98-inch surface for group design reviews, with several students annotating a drawing at once. A ministry meeting room in Msheireb that connects to colleagues abroad can share a presentation from DisplayPort or HDMI and mark it up live. A private school in Al Wakrah equipping a large lecture hall could place an optional Slot-in-PC behind the screen to keep cabling tidy. In every case the room must stay within the 0 to +35°C operating range and 20 to 80% humidity, which means reliable air conditioning when outdoor temperatures pass 45°C.

Planning a 98-inch installation

Weight is 150 kg without the stand, so wall structure and lifting access need checking first.
Dimensions without stand are 2,276 x 1,329 x 123 mm, with a 45 mm symmetrical bezel.
VESA pattern of 400 x 400 mm with M8 holes; the PDW T XXL wall mount is listed as an accessory.
IP40 at the front and IP20 at the back, so choose an indoor position away from open outdoor areas.
Warranty of 3 years including the backlight, with an optional 4th and 5th year extension.

A free site survey from SmartRooms Qatar lets us check wall loading, access routes and power points before a purchase order is raised. Ask for a quotation on a current equivalent or a compatible replacement, and the SmartRooms Qatar team will reply, usually within one working day.

Questions about X981UHD-2 SST

Is the NEC X981UHD-2 SST still sold new by NEC?

No. NEC has discontinued this model, so new units may not be available from the manufacturer. If you already own one, or you are comparing options, send SmartRooms Qatar your room size, input sources and touch requirements. The team will quote a current equivalent or a compatible replacement, and you can compare it side by side with this specification before deciding.

What size is this display and which rooms suit it?

It is a 98-inch (248 cm) display with an active screen of 2,159 x 1,214 mm. It suits large lecture theatres, boardrooms and training rooms where a group needs to work on one surface together. In a small meeting room the screen can dominate the space, and a smaller model usually fits better, so check the viewing distance before ordering.

How many people can write on it at the same time?

ShadowSense tracks up to 12 touch points at once, with touch accuracy below 2 mm. In a design review at a university in Education City, several students can annotate the same drawing without waiting for a turn. Input works with a finger, a glove or a stylus with a 4 mm or larger tip, so presenters are not limited to one pen.

Do I need to install drivers on the host PC?

No. The USB 2.0 touch connection is plug and play and does not need drivers installed on the host PC for the major operating systems. Native multi-touch covers Windows 7 to 11, Linux and Android, while mouse emulation covers Windows XP, Vista and Mac OS, which helps IT teams support mixed systems across a school or ministry.

Does it support pen writing inside Microsoft Office?

Yes. Windows Ink recognises pen writing, erasing and touch gestures in MS Office applications. During a budget review in a government office, a presenter can mark up a spreadsheet directly on the screen without switching between separate input tools, which keeps the meeting moving and the discussion focused on the figures.

Can I run a computer inside the display?

Yes, through the integrated OPS slot, which follows the NEC and Intel OPS standard. NEC lists an optional Slot-in-PC based on Intel Core i5 or i7 processors, with WS7P recommended. Other OPS options include HD-SDI, an HDBaseT receiver and a digital signage player. The OPS slot specification lists a maximum power consumption of 61 W.

Which inputs and connections does it have?

It has one DisplayPort input, four HDMI inputs and two DVI-D inputs, all with HDCP. Audio comes through a 3.5 mm jack, and digital audio is available over HDMI or DisplayPort. Control options include 100 Mbit LAN with SNMP, RS-232 and remote control, so IT teams can manage several displays across a campus over the network.

Can it go outdoors or in a sunny lobby?

Not outdoors. The operating range is 0 to +35°C with 20 to 80% humidity, and the front is rated IP40 while the back is rated IP20. Its touch system rejects ambient light up to full sunlight, but that does not change the temperature limit. In Qatar, where summer temperatures can exceed 45°C, a sunny lobby needs cooling and sun control confirmed before ordering.

How heavy is it and how should it be mounted?

The display weighs 150 kg without its stand. It has a 400 x 400 mm VESA pattern with M8 holes, and NEC lists the PDW T XXL wall mount as an accessory. Because of the weight, have the wall structure and lifting access checked first. SmartRooms Qatar offers a free site survey before a purchase order is raised, which covers exactly these points.

What warranty does it carry?

NEC specifies a 3-year warranty that includes the backlight, with an optional extension covering the 4th and 5th years. Products are covered by the manufacturer's warranty. Confirm the warranty terms with your quotation before issuing a purchase order, so the procurement team can check exactly what is included.

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

Yes. SmartRooms Qatar supplies government ministries and authorities, accepts purchase orders (LPOs) and government tenders, including Monaqasat, and accepts payment by bank transfer, cheque or purchase order. For a ministry meeting room, send the room dimensions and required inputs with your tender reference, and the team will quote against that scope.

How much power does it use if a school runs it daily?

The shipment setting draws 359 W, with under 0.5 W in ECO standby and under 2 W in power savings mode. NEC states an annual consumption of 524 kWh based on four operating hours per day, and an energy efficiency class of B. A school running it for four hours a day in a classroom can use that figure as a planning reference for budgeting.
