Brand: NEC
SKU: nec-x841uhd-2-sst
Availability: Discontinued

Overview

The NEC X841UHD-2 SST is an 84-inch touch-overlay interactive display that the manufacturer has discontinued. It pairs a 3840 x 2160 panel with ShadowSense touch that tracks up to 10 touch points, and an OPS slot for a plug-in PC. Organisations in Qatar that already run this model, or need a current replacement for a meeting room or classroom, can request a quote from SmartRooms Qatar.

What the NEC X841UHD-2 SST is and why it is no longer sold new

The NEC X841UHD-2 SST is an 84-inch interactive display from the MultiSync X Series. It combines ShadowSense touch with a 4K S-IPS panel. NEC has discontinued this model, so this page is written for organisations that already own one, buyers comparing it with newer displays, and anyone searching for a replacement. SmartRooms Qatar can quote a current equivalent or a compatible replacement for your room.

Picture and touch performance that matters in a meeting

The native resolution is 3840 x 2160, with a typical contrast ratio of 1400:1 and a viewing angle of 178 degrees horizontally and vertically. Brightness is rated at 500 cd/m², with the shipment setting at 300 cd/m². The protective glass transmits 92 percent of light, plus or minus 2 percent. Zero-airgap construction reduces the gap between glass and panel, which limits parallax when viewed at an angle.

The ShadowSense touch layer tracks up to 10 touches with accuracy below 2 mm and a response time of 6 to 8 ms. It accepts fingers, gloves and a stylus of 4 mm or more. The touch unit is USB powered over USB 2.0 HID, and setup is plug and play with no driver to install on the host PC. Native multi-touch is listed for Windows 7 to 11, Linux and Android. Windows Ink handles pen writing and erasing in Microsoft Office applications.

Connectivity and the OPS slot

One DisplayPort, two DVI-D and four HDMI inputs, all with HDCP.
A 3.5 mm analogue audio input and a digital audio input via HDMI or DisplayPort.
LAN 100Mbit, RS232 and a remote control wire for control, plus a LAN output.
An integrated Ultra High Resolution OPS slot rated 16 V and 4 A.

The OPS slot follows the NEC and Intel OPS standard. The manufacturer lists a Slot-in-PC based on Intel Core i5 or i7, with WS7P recommended, plus HD-SDI, HDBaseT receiver and digital signage player modules. Mounting a computer inside the panel removes a separate box from the desk and reduces cabling.

Where it fits in Qatar

A boardroom in West Bay where executives hold weekly reviews with teams in Europe, annotating slides directly on the screen.
A lecture room in Education City where a lecturer writes on the display while students work from their own laptops.
A large classroom in Al Wakrah where two or more students can work at the board at the same time.

Planning the installation

The panel weighs 110 kg without its stand and measures 2,000 x 1,194 x 105 mm, so check the wall or floor structure before delivery. VESA mounting uses 400 x 400 mm with M8 holes, and the manufacturer lists PDW T XXL and PD02WHA wall mounts and PD02MHA and PD03MHA trolleys. The rated operating range is 0 to +35°C at 20 to 80 percent humidity, and the front is rated IP40. Summer temperatures in Qatar go above 45°C, so the room needs air conditioning and shade from direct sun. The SmartRooms Qatar team will check the site with you before installation.

Questions about X841UHD-2 SST

Is the NEC X841UHD-2 SST still sold by NEC?

No. NEC has discontinued the X841UHD-2 SST, so the manufacturer no longer offers it as a new unit. If your organisation already runs one, or you are comparing it with newer displays, SmartRooms Qatar can quote a current equivalent or a compatible replacement in the same 84-inch touch-overlay format. Send us the room size, mounting type and the inputs you need, and we will reply with a quotation, usually within one working day.

Who is this 84-inch touch display best suited to?

It suits boardrooms, lecture halls and training rooms where a group gathers around one screen. The active screen area measures 1,860 x 1,046 mm, giving presenters a large writing surface, and the 3840 x 2160 panel keeps text sharp at close range. Ministry meeting rooms in Msheireb or company boardrooms in West Bay are typical settings for a screen of this size.

How many touch points does ShadowSense support, and how accurate is it?

The touch layer supports real multi-touch up to 10 touches, with accuracy of less than 2 mm and a response time of 6 to 8 ms. It works with fingers, gloves and a stylus of 4 mm or more, and the shipment includes a pen and an eraser. In a workshop where several people stand at the screen, each person can write or move objects at the same time without waiting for a turn.

Do I need to install drivers on the computer connected to it?

No. The touch unit is USB powered over a USB 2.0 HID connection, and setup is plug and play with no driver installation on the host PC. Native multi-touch is listed for Windows 7 to 11, Linux and Android, while Windows XP, Windows Vista and Mac OS use default mouse mode. Windows Ink supports pen writing and erasing in Microsoft Office applications. Confirm your operating system with the SmartRooms Qatar team before ordering.

Which video and control connections does it have?

It has one DisplayPort, two DVI-D and four HDMI inputs, all with HDCP support. Audio connections include a 3.5 mm analogue input and a digital input carried over HDMI or DisplayPort. For control, it offers LAN 100Mbit, RS232 and a remote control wire, along with a LAN output. The native resolution is 3840 x 2160 at 60 Hz, so check that your source device can output that resolution.

Can I add a Windows computer inside the display?

Yes, through the integrated Ultra High Resolution OPS slot, which follows the NEC and Intel OPS standard. The manufacturer lists a Slot-in-PC based on Intel Core i5 or i7, with WS7P recommended. Housing the computer inside the panel reduces cables and removes one device from the desk. The OPS slot also takes HD-SDI, HDBaseT receiver and digital signage player modules, so confirm which module you need before ordering.

Can it be installed in a sunny room or lobby in Doha?

Only in a space that stays within the operating range of 0 to +35°C and 20 to 80 percent humidity. Summer temperatures in Qatar go above 45°C, so a sunlit lobby or a room with a west-facing window needs proper air conditioning and shading. The front is rated IP40 and the back IP20, so keep the unit away from dust and sand. The SmartRooms Qatar team will assess the room before confirming the installation.

How heavy is it and how should it be mounted?

The panel weighs 110 kg without its stand and measures 2,000 x 1,194 x 105 mm. It has VESA 400 x 400 mm mounting holes with M8 fixings. The manufacturer lists PDW T XXL and PD02WHA wall mounts, and PD02MHA and PD03MHA trolleys. Because of the weight, we recommend a free site survey to check the wall or floor structure before our team carries out the professional installation.

Is it suitable for a classroom or school hall in Qatar?

It suits a large classroom, science lab or school hall where teachers present and annotate in front of a group. Multi-touch lets two or more students work at the board together, and the pen and eraser in the shipment support writing and erasing. Schools in Al Wakrah or Al Rayyan planning a classroom refit should check airflow and sunlight first, because the operating range is 0 to +35°C.

What warranty applies to the NEC X841UHD-2 SST?

The manufacturer provides a 3-year warranty that includes the backlight, and an optional fourth and fifth year warranty extension is available from the manufacturer. Because this model is discontinued, ask the SmartRooms Qatar team which warranty terms apply to the unit or replacement included in your quotation before you issue a purchase order.

Can a school or ministry order several units through an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and payment by bank transfer, cheque or purchase order. Delivery covers all 8 municipalities of Qatar. For a project with several 84-inch panels, send the room list and mounting details, and we will prepare one quotation, usually within one working day.

Does it have built-in speakers, and can I add better ones?

Yes. It has integrated speakers rated 10 W + 10 W. The manufacturer also lists optional speakers rated 15 W + 15 W, identified as SP-RM1 and SP-TF1. A larger room or a wider audience may justify the optional pair, so measure the room and confirm the speaker choice with the SmartRooms Qatar team before ordering.
