Overview
The NEC 75-inch InfinityBoard 2.1 QL is an all-in-one collaboration display the manufacturer has discontinued. It pairs a 4K IPS touch screen with 20-point InGlass touch, an integrated Huddly IQ camera, 40 W conference speakers and a slot-in Intel Core i7 PC running Windows 10 Professional. It suits meeting rooms in Doha and Lusail that already own this model or need a current replacement. Request a quote for an equivalent.
What this 75-inch InfinityBoard 2.1 QL is
The NEC 75-inch InfinityBoard 2.1 QL is an all-in-one collaboration display built around a 75-inch IPS panel with a native resolution of 3840 x 2160. It combines a touch screen, a camera, conference speakers and a Windows computer in one unit, so a meeting room needs fewer separate devices. The manufacturer has discontinued this model. This page serves organisations that already run it, buyers comparing it with newer collaboration displays, and anyone who needs a replacement for the same room.
Display and touch built for shared writing
The panel is rated at 500 cd/m², with a shipment setting of 350 cd/m², a typical contrast ratio of 1200:1 and 10-bit colour depth. The InGlass touch layer tracks up to 20 touches at once with a response time of 15 ms or less, and accepts finger, glove and stylus input, with styluses of 2 mm or more. Windows Ink supports handwriting. The 3 mm toughened, anti-glare glass transmits 88 percent of light, which helps in rooms with large windows.
- Finger, glove and stylus input on a 75-inch screen
- Up to 20 simultaneous touches
- Landscape and portrait use, with on-screen rotation for portrait
Camera, speakers and the slot-in PC
The integrated Huddly IQ camera outputs 1080p at 30 fps with a 150-degree diagonal field of view and 3x lossless digital zoom. It has no microphone, so audio pickup for remote participants must be planned separately. The conference speakers accept up to 40 W. The OPS slot-in PC uses an Intel Core i7 with 16 GB of DDR4 RAM, a 256 GB SSD, Windows 10 Professional, 802.11ac Wi-Fi and Bluetooth 4.2. The OPS slot is rated for up to 75 W and 4.7 A.
Connections, control and power for IT teams
Inputs include three HDMI and two DisplayPort connections, both with HDCP, plus a DisplayPort output that loops through to the slot-in PC. Control runs over 100 Mbit LAN and RS232, with listed support for AMX NetLinx, Crestron Connected Support, PJLink and SNMP. The unit is also listed as compatible with Cisco Webex Kit. Four USB 3.0 hub ports and a remote control complete the layout. Power draw is 167 W when shipping and under 0.5 W in power-saving mode.
Where it fits in Qatar
- A government authority in West Bay running cross-department reviews, with some attendees joining from abroad through the camera and Quicklaunch one-touch sessions.
- A training centre in Education City running workshops where participants annotate and share their work onto one large screen.
- A hotel meeting room in Msheireb hosting client presentations without a separate computer on the table.
What to plan before ordering
The operating range is 0 to +35 °C with 20 to 80 percent humidity. The room must stay air-conditioned, and the unit should not sit in an unconditioned lobby or in direct sunlight from a window, where Qatar summer temperatures can exceed 45 °C. The unit weighs 80.3 kg without its stand and measures 1944.6 x 1003 x 86 mm. It supports 400 x 400 mm and 600 x 400 mm VESA patterns with M8 holes, so check the wall or trolley plan against the building structure. Our free site survey covers this before installation. The manufacturer's warranty is three years including the backlight, with optional fourth and fifth year extensions.
Because this model is discontinued, the practical route is a quote for a current equivalent or a compatible replacement that matches your room size, mounting and software needs. Request a quote from SmartRooms Qatar and we will confirm which option suits your room.

Questions about 75-inch InfinityBoard 2.1 QL
Is the 75-inch InfinityBoard 2.1 QL suitable for a mid-sized boardroom in Al Sadd?
It suits a mid-sized boardroom where the group works from one shared surface. The 75-inch screen gives everyone a large area for annotation, while the built-in camera and speakers cover remote attendees. Before ordering, confirm the room's air conditioning, wall space and the video platform your team uses, because the camera has no microphone and audio pickup must be planned separately.
Is this model still sold by NEC, and what should I buy instead?
NEC has discontinued the 75-inch InfinityBoard 2.1 QL, so new units may not be available from the manufacturer. SmartRooms Qatar can quote a current equivalent or a compatible replacement that matches the 75-inch size, touch function and built-in conferencing features you need. If you already own this unit, send us its model and your current setup, and our team will advise on compatible options for your room.
What are the main display specifications?
The panel is a 75-inch IPS screen with a 3840 x 2160 native resolution and edge LED backlights. It is rated at 500 cd/m² brightness, with a shipment setting of 350 cd/m², a typical contrast ratio of 1200:1, 10-bit colour depth and 8 ms grey-to-grey response. The active screen area measures 1649.7 x 927.9 mm, and the panel also supports 1920 x 1080 and 4096 x 2160 inputs.
How does the touch screen handle fingers, gloves and pens?
The InGlass touch layer accepts finger, glove and stylus input, with styluses of 2 mm or more. It supports up to 20 simultaneous touches with a response time of 15 ms or less and an accuracy below 1 mm. Windows Ink is supported for handwriting. Two passive styluses are included. Native multi-touch is listed for Windows 7 to 11, Linux and Android, so confirm your operating system before rollout.
Can the built-in camera and speakers handle a video call with overseas teams?
The Huddly IQ camera outputs 1080p at 30 fps with a 150-degree diagonal view, 3x lossless digital zoom and driverless installation. The conference speakers accept up to 40 W and cover the room. The camera has no microphone, so you will need a separate audio solution for remote attendees to hear everyone clearly. Check call platform compatibility with your IT team before ordering.
Can I change the built-in computer or use another OPS module?
The OPS slot follows the open pluggable specification (NEC and Intel OPS standard) and is rated for up to 4.7 A and 75 W. The included slot-in PC is an Intel Core i7 with 16 GB RAM, a 256 GB SSD and Windows 10 Professional. The slot may accept other OPS modules within those limits. Confirm the module's power draw and interface with SmartRooms Qatar before ordering.
What connections and control options does it have?
Inputs include three HDMI and two DisplayPort connections, all with HDCP, plus a DisplayPort output that loops through to the slot-in PC. Control is available over 100 Mbit LAN and RS232, with listed support for AMX NetLinx, Crestron Connected Support, PJLink, SNMP and ASCII commands. Four USB 3.0 hub ports, a 3.5 mm audio jack and a remote control complete the connectivity, which helps building teams integrate it with room systems.
Can it sit in a lobby or a room with direct sun during a Doha summer?
No, not without climate control. The operating temperature range is 0 to +35 °C with 20 to 80 percent humidity, while Qatar summer temperatures can exceed 45 °C. Place it in an air-conditioned room away from direct sunlight and windows, and make sure your cooling can hold the room within the stated range throughout the day, including after hours when the building cools down.
Can a 75-inch unit be wall-mounted in a school hall in Al Rayyan?
It can be, but plan the install first. The unit weighs 80.3 kg without its stand and measures 1944.6 x 1003 x 86 mm. It supports 400 x 400 mm and 600 x 400 mm VESA patterns with M8 holes, and the manufacturer lists wall mounts including the BalanceBox 400 HEAVY and PDW T XL-2. Our free site survey checks wall structure, sightlines and access before installation.
Is it a good fit for a training centre in Education City running mixed-language workshops?
The hardware suits workshops where trainers annotate slides and participants share content from their own devices. The touch layer accepts pen and finger input, and the slot-in PC runs Windows 10 Professional with Windows Ink. Language support depends on the applications you install rather than the display itself, so test your Arabic and English materials on the PC before a training schedule begins.
How does Quicklaunch help a government meeting room in West Bay with overseas teams?
Quicklaunch is a meeting room interface with multi-platform integration that lets staff start a meeting from one tap. The Quicklaunch Ultimate Edition is listed with three years of maintenance and support. Combined with the Huddly camera and speakers, it helps teams join calls faster. The manufacturer also lists FlatFrog Board and Hoylu, each with a single-user licence, and Mosaic Connect as free software.
What warranty and purchase options apply?
The manufacturer lists a three-year warranty that includes the backlight, with optional fourth and fifth year extensions. SmartRooms Qatar offers supply, delivery across Qatar and professional installation. Government and school buyers can order against a purchase order or LPO, and payment can be made by bank transfer, cheque or purchase order. Request a quote and we will confirm which warranty extension is available for your order.
