Availability: Discontinued

Overview

The NEC MultiSync V423 TM-2 is a 42-inch landscape and portrait touch display with infrared touch that accepts finger, gloved and stylus input and up to six simultaneous touches. Its 1920 x 1080 panel reaches 450 cd/m² and it includes an OPS slot for an optional Windows slot-in PC. NEC has discontinued this model, so SmartRooms Qatar can quote a current equivalent or compatible replacement for schools, offices and meeting rooms across Qatar.

NEC V423 TM-2: a discontinued 42-inch infrared touch display

The NEC MultiSync V423 TM-2 is a 42-inch touch display from the MultiSync V Series. NEC has discontinued this model. This page is written for organisations that already run one, for buyers comparing it with newer touch displays, and for anyone searching for a replacement. SmartRooms Qatar supplies current equivalents and compatible replacements, and quotations usually come within one working day.

Infrared touch for gloves and styluses

The V423 TM-2 uses infrared touch with an accuracy of less than 1 mm. It takes input from a finger, a gloved hand or a stylus, and it recognises up to six touches at the same time. That combination suits teaching groups who take turns at the board and site teams who need to operate a screen while wearing gloves.

Touch methods: finger, gloves and stylus
Multi-touch: up to six simultaneous touches
Setup: USB 2.0 HID link with native multi-touch on Windows 7 to 11, Linux and Android
Mac OS: operates as a default mouse

Display, glass and connections

The 42-inch S-IPS panel has a 930 x 523 mm active area and a native resolution of 1920 x 1080 at 60 Hz. It is rated at 450 cd/m² in its shipment setting, with a 270 cd/m² eco setting, and a typical contrast ratio of 1300:1. The 3 mm toughened front glass has an anti-glare coating and light transmission of 92% (±2%). Inputs include HDMI 1.3, DisplayPort, DVI-D and a D-sub 15-pin connector, plus composite video on BNC. Control options are LAN at 100 Mbit, RS232 and an infrared remote sensor.

Scenarios across Qatar

A private school in Al Wakrah fitting out classrooms for younger pupils, where up to six touches let small groups work at the screen together.
A training centre in Education City running workshops where facilitators write with a stylus and trainees wear gloves during lab sessions.
A meeting room in Msheireb or West Bay used for video calls with teams abroad, with the display connected through HDMI or DisplayPort.

What to plan before ordering

Plan the room around the operating range. This model is rated for 0 to +35 °C and 20 to 80% humidity, so it belongs in an air-conditioned space rather than a hot lobby, an uncooled site office or a spot in afternoon sun from a window. The unit weighs 25 kg without its stand, measures 1,013 x 602.5 x 81.1 mm, and supports a 300 x 300 mm VESA pattern with M6 holes. Its IP40 front and IP20 back ratings suit indoor use. A free site survey from SmartRooms Qatar can confirm wall strength, mounting height and cable routes before installation.

The integrated speakers are 10 W + 10 W, and an optional 15 W + 15 W speaker set is available. The OPS slot is rated 16 V and 4 A with a maximum draw of 61 W, and it accepts a slot-in PC or digital signage player from the optional list. Typical power use is 88 W in the eco shipment setting, with an energy efficiency class B rating and an annual consumption of 129 kWh based on four operating hours a day. The manufacturer's warranty covers three years including the backlight, with optional fourth and fifth year extensions.

Questions about V423 TM-2

Is the NEC V423 TM-2 still available new?

NEC has discontinued the V423 TM-2, so new units may not be available from the manufacturer. SmartRooms Qatar can quote a current equivalent or a compatible replacement for a 42-inch touch display. Send us the number of units, the room size and whether they will be wall-mounted, and we will usually return a quotation within one working day. We also handle purchase orders (LPOs) and government tenders.

What is the NEC V423 TM-2 best suited for?

It suits a 42-inch touch display for a classroom, a small meeting room or a reception area where one or two people work at the screen at a time. Its 16:9 panel at 1920 x 1080 shows lessons, spreadsheets and presentations clearly, and touch works with a finger, gloves or a stylus. Large lecture halls usually need a bigger screen or several units.

Can staff use it while wearing gloves?

Yes. The infrared touch method accepts a finger, a gloved hand or a stylus, with touch accuracy of less than 1 mm. This helps site supervisors in the Industrial Area or clinic staff who wear gloves during their shifts. Check the glove type your team uses against the stated touch methods before you confirm the quantity.

Do I need to install drivers on the PC?

No driver installation is required on the host PC for the major operating systems. Native multi-touch is supported on Windows 7 to 11, Linux and Android over a USB 2.0 full-speed HID connection that is powered from USB. On Mac OS the display operates as a default mouse device.

How many people can touch the screen at once?

The screen supports real multi-touch of up to six touches at the same time. In a primary classroom, that lets small groups solve a puzzle or sort words together at the board. In a meeting in Doha, two or three presenters can annotate the same slide. The toughened 3 mm front glass has an anti-glare coating that helps visibility.

Is it bright enough for a room with lots of daylight?

The panel is rated at 450 cd/m² in its shipment setting and 270 cd/m² in the eco setting, with a typical contrast ratio of 1300:1. The touch sensing is rated to work up to full sunlight, at approximately 150,000 lux. In rooms with large windows, place the screen away from direct sun lines and test the brightness setting on site during the survey.

Can it run in a Qatar summer without air conditioning?

No. The operating temperature range is 0 to +35 °C with 20 to 80% humidity. Outdoor temperatures in Qatar often exceed 45 °C in summer, so the display needs a steadily cooled, air-conditioned room rather than a hot entrance, an outdoor pavilion or an unventilated site cabin. Storage is rated from -20 to +60 °C. Confirm room conditions with the SmartRooms Qatar team during the site survey.

How do I wall-mount it, and how heavy is it?

The display weighs 25 kg without its stand and measures 1,013 x 602.5 x 81.1 mm. It has a 300 x 300 mm VESA pattern with four M6 holes. NEC lists wall mounts for this model, including PD02W T M L and PD03W T M P. Request a free site survey from SmartRooms Qatar to check wall strength, mounting height and cable routing before installation.

Which ports are available for a laptop or desktop PC?

Video inputs are HDMI 1.3, DisplayPort and DVI-D, all with HDCP, plus a D-sub 15-pin analogue input and composite video on BNC. Audio input is a 3.5 mm jack, and digital audio is available over HDMI or DisplayPort. A DVI-D output with HDCP lets you pass the signal to another display. Control is available through LAN at 100 Mbit, RS232 or the remote sensor.

What is the OPS slot for?

The integrated slot is compatible with the Intel and NEC OPS standard and accepts a slot-in PC, so Windows can run inside the display without an external computer. It is rated 16 V and 4 A with a maximum draw of 61 W. Listed options include Intel Atom, Celeron and Core i5/i7 slot-in PCs, a digital signage player and an HDBaseT receiver. Fewer external cables can mean fewer points of failure.

Does it have built-in speakers for a school hall or training room?

Yes, it includes integrated speakers rated 10 W + 10 W. An optional speaker set rated 15 W + 15 W is listed for this model, which helps in training rooms or school halls where attendees sit further back. Compare room size and background noise before choosing between built-in and optional speakers. For large halls, an external sound system is usually more suitable.

What warranty and accessories come with the display?

The manufacturer's warranty covers three years including the backlight, with optional fourth and fifth year extensions. The box includes the display, a DVI-D cable, a power cable, a remote control and a USB cable. NEC's LAN control software is available as a free download. The stand, speakers, trolley and wall mounts are listed as options, so request a quotation that includes what you need.
