NEC M491 PCAP (Discontinued) · Replacements in Qatar

Name: NEC MultiSync M491 PCAP 49-inch Interactive Touch Display
Brand: NEC
SKU: nec-m491-pcap
Availability: Discontinued

Overview

The NEC M491 PCAP is a 49-inch 4K interactive touch display with PCAP touch technology that tracks up to 20 touch points for finger and pen input. Its edge-to-edge glass has no bezel, and it includes 10 W + 10 W speakers and a 3-year warranty covering the backlight. NEC has discontinued this model, so SmartRooms Qatar quotes a current equivalent or compatible replacement for meeting rooms and classrooms.

What the NEC M491 PCAP is and who it suits

The NEC M491 PCAP is a 49-inch interactive display with projected-capacitive (PCAP) touch, recognising up to 20 touches from a finger or a conductive passive stylus. Its IPS panel delivers a native 3840 x 2160 resolution, 500 cd/m² brightness without glass and a contrast ratio above 8,000:1. NEC has discontinued this model. This page serves organisations that already run one, buyers comparing it with newer displays, and anyone who needs a replacement for a room that depends on touch.

Touch, glass and picture quality

The protective glass is 4.45 mm thick, transmits 85% of light (plus or minus 5%), has a haze level between 5% and 10%, and carries a hardness rating of 6. The glass runs edge to edge with no bezel, so the front reads as one flat surface. Touch accuracy is plus or minus 1.5 mm. Windows Ink and palm rejection are not supported, so the panel suits presenting, pointing and annotating better than handwriting with a palm resting on the glass.

Connectivity, control and built-in options

The inputs include one DisplayPort and two HDMI ports, all with HDCP, plus a USB 2.0 port for the MediaPlayer and a powered USB port rated at 10 W. Control runs over LAN at 100 Mbit, RS232 and a 3.5 mm remote control wire. The touch interface is listed for Android, Linux, Raspberry Pi and Windows. The panel accepts Intel Smart Display Modules (Large and Small) up to 66 W and has a slot for a Raspberry Pi Compute Module 4.

Audio: integrated 10 W + 10 W speakers, a 3.5 mm audio output and HDMI ARC.
Control: Crestron Connected, AMX NetLinx, PJLink, SNMP and HDMI CEC support.
Sensing: three temperature sensors with programmable triggered actions.

Where it fits in Qatar

A 49-inch screen suits a meeting room for six to ten people, a classroom where students sit close, or a reception desk. Three typical situations:

A government reception in Msheireb running visitor check-in or wayfinding around the clock, using the 24/7 operating rating and the USB media player for looping content.
A training centre in Education City where instructors annotate with a pen during sessions, using the 20-point touch.
A consultancy meeting room in West Bay where Doha staff share screens with colleagues abroad. The source lists the panel as tested compatible with Barco ClickShare (Conference).

Planning the installation and the environment

The operating temperature range is 0 to +35 °C, with operating humidity of 20% to 80%. Summer temperatures in Qatar exceed 45 °C, so install the display in an air-conditioned room, keep it out of direct sunlight and away from dusty airflow, and confirm the location with the SmartRooms Qatar team before work begins. The front is rated IP5x and the back IP2x.

The panel weighs 30.3 kg and measures 1,139.9 x 669.9 x 65.08 mm. Its VESA pattern is 300 x 300 mm with four M6 holes, so the wall mount or trolley must match those dimensions and the load. A free site survey before wall mounting is worth booking for a panel this size. The internal power supply accepts 100-240 V AC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Check the supplied power cable against your BS 1363 sockets when you request a quote.

Warranty, purchasing and next step

The manufacturer's warranty runs for three years and includes the backlight. Organisations buying through an LPO or a government tender can send the model and quantity in one request. Because NEC has discontinued the M491 PCAP, request a quote for a current equivalent or compatible replacement. SmartRooms Qatar will confirm specifications, delivery to all 8 municipalities and installation, usually within one working day.

Questions about M491 PCAP

Is the NEC M491 PCAP still sold by NEC?

NEC has discontinued the M491 PCAP, so the best route is a quote for a current equivalent or a compatible replacement. Tell us your room size, how many people will touch the screen at once, and the control system in use. We will match a model to those needs before you approve a purchase order.

How many touch points does it support, and does it take pen input?

The M491 PCAP supports up to 20 touch points, using a finger or a conductive passive stylus, with touch accuracy of plus or minus 1.5 mm. Windows Ink and palm rejection are not supported, so teachers and presenters should write with a pen and keep the palm away from the glass to avoid unwanted input.

Will it connect to Crestron, AMX or Barco ClickShare systems?

Yes, for all three. The panel is Crestron Connected certified, lists AMX NetLinx support, and is tested compatible with Barco ClickShare (Conference). It also supports PJLink, SNMP, HDMI CEC and RS232 control. Confirm your exact control protocol and wireless sharing model with our team before ordering.

How can an IT team manage several displays remotely?

The data lists NaViSet Administrator 2, a free download, for remote control, automated email alerts and planning maintenance. Scheduled timers, disabled hardware buttons, disabled IR functionality and an emergency notification feature are also listed, which helps IT teams in a school or ministry lock down shared rooms.

Can a government reception in Msheireb run it around the clock?

The data lists 24/7 operating hours. The operating temperature range is 0 to +35 °C, so the reception must be air-conditioned, and the screen should stay out of direct sunlight and entrance draughts. Summer temperatures in Qatar exceed 45 °C, so confirm the room conditions with the SmartRooms Qatar team during the site survey.

Is it suitable for a training centre in Education City where instructors write during sessions?

Yes for annotation, because the panel accepts up to 20 touches from a finger or a conductive passive stylus. It does not support Windows Ink or palm rejection, so instructors should write with a stylus rather than resting their hand on the glass. The touch interface is listed for Android, Linux, Raspberry Pi and Windows.

Can a meeting room in West Bay share screens with colleagues abroad?

The data lists the panel as tested compatible with Barco ClickShare (Conference). It has two HDMI inputs and one DisplayPort input, all with HDCP, plus LAN at 100 Mbit for network control. Check your wireless sharing setup against the compatibility list before purchase, and include the room layout in your quote request.

What wall mount or trolley does a 49-inch panel of this weight need?

The panel weighs 30.3 kg and measures 1,139.9 x 669.9 x 65.08 mm. Its VESA pattern is 300 x 300 mm with four M6 holes. NEC lists the PD04 Tipster Trolley and the PDW S 32-55 L and PDW S 32-65 P wall mounts as options, so confirm which one fits before quotation. A free site survey is available before wall mounting.

Can a private school in Al Wakrah loop class schedules from a USB drive?

Yes, through its MediaPlayer. It reads a USB 2.0 drive formatted as FAT16 or FAT32 and plays JPG images, MP4 and TS video up to 3840 x 2160 at 60 Hz, and MP3 audio up to 320 kbit/s. Check that your schedule files use these formats, since the MPG and WMV limits are lower at 1080p.

What power supply and sockets does it need in Qatar?

The internal power supply is rated 100-240 V AC at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Power consumption is below 0.5 W in power saving mode and below 2 W in networked standby. A power cable is included; confirm it suits BS 1363 sockets during your site survey.

What does the warranty cover, and what is in the box?

The data lists a 3-year warranty that includes the backlight, with additional services available. The box contains the display, a remote control with two AAA batteries, an HDMI cable, a power cable, a USB cable and a setup manual. Organisations buying on an LPO or a government tender can include the model and quantity in a single request.

Can I install it in a lobby near a window in Al Khor?

Confirm this first. The data gives an operating temperature of 0 to +35 °C and an ingress rating of IP5x at the front and IP2x at the back, but it gives no outdoor or direct-sunlight rating. Keep the panel out of direct sun and dust, and have SmartRooms Qatar check the location during a site survey before installation.
