NEC C981Q SST (Discontinued) · Replacements in Qatar

Name: NEC MultiSync C981Q SST 98-inch Interactive Touch Display
Brand: NEC
SKU: nec-c981q-sst
Availability: Discontinued

Overview

The NEC MultiSync C981Q SST is a 98-inch 4K touch display, now discontinued by NEC. It uses an IPS panel with 1300:1 typical contrast, 10-bit colour and ShadowSense touch that needs no drivers on major operating systems. An OPS slot and three HDMI inputs suit boardrooms and classrooms. Organisations that already own one, or need a replacement, should request a quote for a current equivalent.

What the NEC C981Q SST is and why it is discontinued

The NEC MultiSync C981Q SST is a 98-inch LCD interactive display from the MultiSync C Series, built around ShadowSense touch. NEC has discontinued this model, so it is no longer in the current range. This page serves organisations that already run one, buyers comparing it with newer displays, and anyone looking for a replacement for the same room. SmartRooms Qatar can quote a current equivalent or a compatible replacement.

Panel and touch performance for large groups

The IPS panel uses direct LED backlights and a native resolution of 3840 x 2160, giving a 2,158.9 x 1,214.4 mm active area. Typical contrast is 1300:1, colour depth is 10-bit, and the viewing angle is 178 degrees both ways at contrast above 10:1. Brightness is listed at 350 cd/m², with a shipment setting of 245 cd/m². A 5 mm toughened glass front with 92 percent light transmission (+/- 2 percent) protects the panel.

ShadowSense touch works with fingers, gloves and styluses of 2 mm or more. The spec sheet lists up to 12 simultaneous touches, accuracy under 2 mm and ambient light rejection up to full sunlight, which helps near windows. Windows Ink recognises pen writing and erasing in MS Office applications. Palm rejection is not listed for this model, so brief presenters to write with the pen rather than the side of the hand.

Connectivity, expansion and control

Two DisplayPort and three HDMI inputs carry HDCP, and a DisplayPort output loops the signal through to a further display. The OPS slot accepts a plug-in computer module rated at 4.7 A and 75 W, so a meeting room can run its presentation PC inside the panel. A Compute Module 3 slot and USB 2.0 ports for compute modules, one of them powered at 5V/2A, add further options.

Network control: 100Mbit LAN, RS232 and a 3.5 mm remote control jack
Audio: integrated 10 W + 10 W speakers, with optional speakers listed
Sensors: three temperature sensors, an NFC sensor with a 2 cm range and an optional external human sensor with a 4 to 5 m range

Where it fits in Qatar

In a ministry or authority boardroom in Doha, a 98-inch screen lets a group review Arabic and English documents side by side, with a shared PC in the OPS slot. It suits meetings that connect Doha with teams abroad.

A training centre in Education City or Al Sadd could use it for hands-on workshops, where several learners write on the glass with the pen and eraser included in the box.

An operations briefing room in Lusail gains from the IP5x front rating against dust, but the room must stay within the display's temperature range.

Planning the installation

Without its stand, the display weighs 152 kg and measures 2,256.5 x 1,310 x 110.7 mm. The rear offers 400 x 400 and 600 x 400 mm VESA patterns with M8 fixings, and the source lists a trolley and a wall mount among the options. Check the wall or floor load, the lift route and the cable path before the panel arrives. SmartRooms Qatar offers a free site survey for this purpose, and professional installation can follow an accepted quotation.

The operating range is 0 to +35°C with 20 to 80 percent humidity. Summer temperatures in Qatar can exceed 45°C, so the room must be air-conditioned and kept within that range. Use the listed power figures, 252 W in eco mode and under 0.5 W in power saving mode, when sizing the electrical circuit and cooling. The shipping list does not include a power cable, so confirm power accessories in the quotation.

Because NEC has discontinued the C981Q SST, request a quote from SmartRooms Qatar for a current equivalent or a compatible replacement. Share your room size, viewing distance, required inputs and mounting wall, and the team will confirm the fit before you commit.

Questions about C981Q SST

Is the NEC C981Q SST still available from SmartRooms Qatar?

No. NEC has discontinued this 98-inch model, so it is no longer in the current range. If you need a touch display of this size for a boardroom, school hall or viewing room, request a quote. SmartRooms Qatar will suggest a current equivalent or a compatible replacement based on your room layout, required inputs and mounting method.

What panel type and resolution does it use?

The panel is IPS with direct LED backlights and a native resolution of 3840 x 2160 (4K UHD). It also accepts 1920 x 1080, 1920 x 2160 and 4096 x 2160 inputs. Typical contrast is 1300:1 and the viewing angle is 178 degrees. In a large Doha boardroom, text on a shared spreadsheet stays readable for people seated at the far end of the table.

Does the touch function need drivers installed on the host PC?

No. ShadowSense connects as a USB HID device powered over USB, so a single USB cable from the display to the host PC is enough. The manufacturer lists native multi-touch for Windows 7 to 11, Linux and Android, and says set-up works without drivers on all major operating systems.

Can I use native multi-touch with a Mac?

Not natively. The source data lists native multi-touch for Windows 7 to 11, Linux and Android, while Mac OS works through the default mouse function. If your design or media team works on Macs, plan for mouse-style control rather than multi-touch, and confirm the set-up in your quotation before ordering.

What is the operating temperature range, and why does it matter in Qatar?

The listed operating range is 0 to +35°C with 20 to 80 percent humidity. Summer temperatures in Qatar can exceed 45°C, so the display must sit in an air-conditioned room that keeps conditions within that range. Before ordering for a lobby with glass frontage or a hall that receives direct sun, confirm cooling and placement with the SmartRooms Qatar team.

Does it support OPS, and what can I plug into the slot?

Yes. The OPS slot takes an open pluggable computer module with a maximum of 4.7 A and 75 W. Listed options for this model include modules with Intel Atom, Celeron and Core CPUs, an HDBaseT receiver and an OPS-2C Quad 3G SDI option. A presentation PC inside the panel removes the need for a tower beside the screen.

Is it suitable for a classroom or lecture space at Education City?

It suits a large lecture hall, seminar room or shared studio where a group needs to see the same content and mark it up together. The pen and eraser in the box support direct writing. The built-in 10 W + 10 W speakers are intended for smaller rooms, and listed optional speakers can be quoted for larger spaces.

How heavy is it, and what mounting does it need?

Without its stand the display weighs 152 kg and measures 2,256.5 x 1,310 x 110.7 mm. The rear has VESA patterns of 400 x 400 and 600 x 400 mm with M8 fixings. Check the wall's load capacity before mounting. SmartRooms Qatar offers a free site survey to confirm this for a wall in a Doha office, school or hotel conference room.

Can it be controlled remotely or integrated with building systems?

Yes. Control inputs include 100Mbit LAN, RS232 and a 3.5 mm remote control jack. The data lists support for AMX NetLinx, Crestron Connected, PJLink, SNMP and ASCII control commands, plus a Scheduler function. Facilities teams can therefore schedule operation and monitor the display over the network from a central location.

What is included in the box?

The shipping content lists the display, a DisplayPort cable, a pen and eraser, a remote control, a USB cable and a CD-ROM with user guides and manuals. A power cable is not listed, so confirm any power accessories in the quotation before ordering for your site.

Can a government ministry or school order it through an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, with payment by bank transfer, cheque or purchase order. State the number of units, the size and the replacement purpose in your request so the quotation matches your procurement route.

Which sensors does it include?

It has three integrated temperature sensors with programmable triggered actions, an NFC sensor with a 2 cm range that requires the free NEC Android app, and an optional external human sensor with a 4 to 5 m range. The human sensor's triggered actions can be programmed, which suits a meeting room where the display should respond when someone enters.
