C751Q SST

The NEC MultiSync C751Q SST is a 75-inch LCD interactive display with ShadowSense touch, and NEC has discontinued this model. This page is for organisations that already own one, buyers comparing it with newer panels, and anyone looking for a replacement. SmartRooms Qatar can quote a current equivalent or a compatible replacement for the same room, so you can match the screen size, touch behaviour and connectivity you need.

Display and touch performance for group work

The panel is a 3840 x 2160 IPS display with edge LED backlighting, rated at 350 cd/m² brightness with a 254 cd/m² shipment setting and a typical contrast ratio of 1,200:1. Its 178-degree viewing angles keep text readable from the back of a classroom or the far end of a boardroom table. Up to 10 touch points can work at once, and touch accuracy is rated below 2 mm, so annotations land where people write.

The touch layer accepts fingers, gloves and styluses with a tip of at least 2 mm. It connects over USB 2.0 HID and does not require drivers to be installed on the host PC. Native multi-touch is listed for Windows 7 to 11, Linux and Android, while Mac OS works in default mouse mode. Windows Ink recognises pen writing, erasing and gestures inside Microsoft Office applications. The protective glass is 5 mm thick with a single-sided anti-reflective coating and 92% light transmission, and the manufacturer rates ambient light rejection up to full sunlight, approximately 100,000 lux.

Connectivity, computing and content options

• Two DisplayPort and three HDMI inputs, both with HDCP
• DisplayPort output for loop-through to a second screen
• OPS slot for a plug-in PC module, including Intel Atom, Celeron and Core options
• Compute Module 3 slot for NEC or Raspberry Pi Compute Module 1 and 3
• 100Mbit LAN, RS232 and remote control jack for control

The built-in MediaPlayer reads microSD and USB storage, with formats including MP4, MOV, WMV, JPG, PNG and MP3, so content can run without a computer attached. The data also lists PJLink, SNMP, AMX NetLinx, Crestron Connected Support and Cisco Webex Kit compatibility, which should be confirmed against your exact conferencing setup. Integrated speakers are rated at 10 W + 10 W, with optional 15 W + 15 W speakers listed.

Where it fits in Qatar

A secondary school in Al Wakrah refitting a science lab could use a 75-inch panel so students at the back can read a shared worksheet, while two pupils annotate the screen at the same time. In West Bay or Lusail, a company boardroom linking a Doha team with colleagues abroad needs a clear screen and a dependable conferencing connection, so confirm compatibility before ordering. A ministry reception area in Msheireb or a training centre in Education City could loop welcome slides from the MediaPlayer when no PC is attached.

What to plan before ordering

The display weighs 77.5 kg without a stand and measures 1,746 x 1,025 x 88.5 mm without a stand. Its VESA patterns are 400 x 400 and 600 x 400 with M8 fixings, and the listed accessories include the BalanceBox 400 HEAVY and PDW T XL-2 wall mounts plus three trolley models. Because of its weight, SmartRooms Qatar offers a free site survey before wall mounting to check the wall structure, sightlines and cable route.

Operating temperature is rated from 0 to +30°C with 20 to 80% humidity. Qatar summer temperatures often exceed 45°C, so the room needs reliable air conditioning, and the room conditions should be confirmed with the SmartRooms Qatar team before installation. Typical power consumption is 207 W in the Eco shipment setting, and standby draw is below 0.5 W. Confirm the power supply and socket arrangements for your site as part of the quotation.
