LED & Large Format Displays

A large format display is a commercial LCD screen of 75 inches or more, built for long daily use in meeting rooms, lobbies and public spaces. The main models in this collection are the 75, 86 and 98-inch MAXHUB CMA series and the 85-inch Samsung QM85C, all 4K UHD at 3840 × 2160.

Compared with a home TV, they are rated for 24/7 operation, use anti-glare or non-glare screens, support portrait installation and add control ports such as RS232C or LAN. The MAXHUB CMA series is rated for a 50,000-hour life.

Choose a single 98-inch screen when the image needs to be up to about 98 inches, and a video wall when it must be larger or a special shape. A screen such as the MAXHUB ND98CMA has no seams and needs only one power and signal connection.

A video wall of 55-inch panels, such as the LG 55VM5J-H with a 1.74 mm bezel-to-bezel gap, can grow to any size, but shows thin lines between panels and needs a dedicated mount, calibration and often a video wall controller. A 2 × 2 wall of 55-inch panels gives about 110 inches.

Yes, in most meeting and training rooms. A 98-inch 4K display such as the MAXHUB ND98CMA gives a bright image at 500 nit with the room lights on, needs no lamp or filter changes and is rated by MAXHUB for 24/7 operation and a 50,000-hour life.

A projector is still the better choice when the image must be wider than about 2.2 m, the size of a 98-inch screen, or when the wall cannot carry the 69.90 kg weight of the ND98CMA. Check the delivery route too, because a 98-inch carton needs wide doors and a large lift.

They weigh about 35 kg to 70 kg. In this collection the MAXHUB ND75CMA weighs 34.65 kg, the Samsung QM85C 41.9 kg, the MAXHUB ND86CMA 43.15 kg and the MAXHUB ND98CMA 69.90 kg.

That weight needs a solid wall, or a floor stand rated for it, and at least two people for installation. The Samsung QM85C uses a 600 × 400 mm VESA pattern and is 28.5 mm deep, so it sits close to the wall on a slim mount.

Yes, on the MAXHUB CMA series. The 75, 86 and 98-inch CMA models have a full-function USB-C port for screen sharing that also charges the connected laptop at up to 65 W, so one cable carries picture and power.

The Samsung QM85C uses HDMI and DisplayPort instead, with 3 HDMI 2.0 inputs and a DisplayPort 1.2 input. Check that the laptop's USB-C port supports DisplayPort video before relying on one cable, because some USB-C ports only charge or carry data.

An OPS slot is a standard bay that takes a plug-in computer, called an OPS PC, so the screen runs Windows software or a signage player without an external computer and cables. OPS stands for Open Pluggable Specification.

The MAXHUB ND75CMA, ND86CMA and ND98CMA have an 80-pin OPS slot. The module is sold separately; choose one that matches the 80-pin slot and is approved by MAXHUB, because power and connector support differ between makers.

Yes, if the model is rated for it. The MAXHUB CMA series and the Samsung QM85C are rated by their manufacturers for 24/7 operation, and MAXHUB rates the CMA series for a 50,000-hour life.

For continuous use, keep the room within the rated operating range (0 °C to 40 °C for the Samsung QM85C), leave the ventilation space the manual requires and use the screen's schedule to switch off when the space is closed, which extends the life of the backlight.

Yes, on the main models here. The MAXHUB CMA series supports portrait and landscape modes, and Samsung shows the QM85C in both orientations. Portrait screens suit lobby and retail content such as posters, menus and digital standees.

In portrait the mount must be rated for vertical use, and the content must be designed in a 9:16 format. Check the installation manual for the correct rotation direction, because it affects ventilation and the position of the control ports.

Choose an anti-glare or non-glare screen for rooms with windows or strong lighting, because reflections reduce readability more than brightness does. The Samsung QM85C has a 25% haze anti-glare surface, and the MAXHUB CMA series has a non-glare coating.

Both are 500 nit indoor displays, so in the UAE keep them away from direct sun through glazing. The MAXHUB CMA series also has a conformal coating that reduces the risk of damage from salt, dust and humidity in coastal buildings.

They are managed over the network with the manufacturer's software. MAXHUB provides MAXHUB Pivot for IT teams to manage CMA displays and send content to them remotely, and the Samsung QM85C runs Tizen 7.0 with 16 GB of storage for scheduled content.

Remote management lets one team switch screens on and off, update firmware and change content across several rooms or branches. Plan a wired LAN point behind each screen, because Wi-Fi is less reliable for large content updates.
