What the 75-inch TT-7522S is

The Newline TT-7522S is the 75-inch member of the S Series, a range of interactive displays for classrooms and teams introduced in 2023. The manufacturer has discontinued this model, so this page serves organisations that already own one, buyers comparing it with other panels, and anyone who needs a 75-inch replacement. Its 4K LED panel offers 3840 × 2160 resolution across a 1650 × 928 mm display area, with a 178° viewing angle so people seated to the side of the room see the same picture.

Touch, writing and connections that matter in a room

The infrared touch layer recognises 20 touch points at once, so several people can write or annotate together. Palm rejection separates a pen or fingertip from a palm or wrist, which cuts down on stray marks when a presenter rests a hand on the glass. For cabling, the panel provides three HDMI 2.0 inputs, a DisplayPort 1.2 input, a VGA input, a USB Type-C port with 65W Power Delivery and an HDMI 2.0 output. An integrated OPS-PC slot and an RS-232 control input let the panel work with a plug-in computer module and external control systems.

Audio, software and the optional camera

Two 20W speakers are built in, rated at 80 dB ±3 dB sound pressure level, which covers small and medium rooms without extra loudspeakers. The system runs Android 11 on a quad-core Arm Cortex-A55 processor with 4GB RAM and 32GB ROM, and the source describes a dual system design with Android 11 and Windows. Wi-Fi 6 is integrated. A 4K camera with a 120° field of view and 15° tilt adjustment is a separate optional add-on, not standard equipment.

Where it fits across Qatar

A private school in Al Rayyan refitting a mid-sized classroom could use the panel for lessons that combine handwritten notes with Android apps, while the teacher's laptop charges over a single Type-C cable. In West Bay, a consultancy's boardroom can run video calls with teams abroad, using the RJ-45 network port or Wi-Fi 6. A training room in Msheireb or a training centre in Education City can wall-mount the panel for staff sessions with slides, video and shared documents.

Planning the installation

Net weight 51.5 kg; gross weight 64.5 kg
Outline 1735 × 1047 × 112 mm; packed 1859 × 1160 × 227 mm
Wall-mounted or on an optional mobile stand
Operating range 0–40°C at 20–80% RH, non-condensing
Rated AC 100–240 V, 4.5 A; standby below 0.5 W

Book a free site survey before wall mounting, particularly in rooms with large glazed walls. Plan at least two people for lifting, and keep the room inside its operating range with working air conditioning, which matters during Qatar's summer when outdoor temperatures can exceed 45°C. Rooms that run above 40°C are not suitable for this panel.

Questions about TT-7522S

Is the Newline TT-7522S still sold new?

No. The manufacturer has discontinued the TT-7522S, the 75-inch model in its 2023 S Series. If you need a 75-inch 4K touch display for a classroom, meeting room or training space, request a quote for a current equivalent or a compatible replacement. Send the room size, mounting plan and connectivity you need, and the SmartRooms Qatar team will match the closest option.

How does the TT-7522S compare with the 65-inch and 86-inch S Series models?

The TT-7522S sits between them. Its display area is 1650 × 928 mm, against 1428 × 804 mm for the 65-inch TT-6522S and 1895 × 1066 mm for the 86-inch TT-8622S. Net weight is 51.5 kg, compared with 39 kg and 64.5 kg. All three share 4K resolution, LED technology, a 178° viewing angle and infrared touch, so the choice mainly depends on room size and the wall or stand the panel will use.

Is a 75-inch panel the right size for a classroom in Al Rayyan or Education City?

It suits a mid-sized classroom or seminar room where students sit several metres from the screen and need to read smaller text. A private school in Al Rayyan fitting out a teaching room might choose it over a 65-inch model when the wall has space for a larger panel. Before deciding, measure the viewing distance from the back row and check the clearance for a stand. The 4K resolution keeps text sharp at this size.

How does the touch function work?

The TT-7522S uses infrared touch with 20 touch points, so several people can write or tap at once. The specifications list a passive pen as its writing tool. Palm rejection distinguishes between a pen or fingertip and a palm or wrist, reducing accidental marks when a presenter rests a hand on the glass. The anti-glare, anti-fingerprint glass has 8H surface hardness and 88% ± 3 transparency.

Can a presenter in West Bay connect a laptop with one cable?

Yes, if the laptop has a USB Type-C port that supports video output. The Type-C input carries video, audio and touch signals and delivers 65W Power Delivery, so the laptop can charge while it presents. This suits consultancies running video calls with teams abroad, because one cable keeps the table tidy. Check your laptop's Type-C specification before ordering.

Which ports and inputs does it have?

It has three HDMI 2.0 inputs, one DisplayPort 1.2 input, one VGA input with VGA audio, a microphone input and one USB Type-C port with 65W Power Delivery. Outputs include one HDMI 2.0 output, an audio line out and S/PDIF. Control and networking use an RS-232 input and an RJ-45 network port with IN and OUT connectors. Two USB Type-B touch ports, two USB 3.0 Type-A and two USB 2.0 Type-A ports complete the list.

Does it run Android, Windows or both?

The source data describes a dual system design with integrated Android 11 and Windows OS, so teachers and teams can choose their preferred software. The panel has a quad-core Arm Cortex-A55 processor, 4GB RAM and 32GB ROM, and Wi-Fi 6 is integrated for network connection. It also has an OPS-PC slot for a plug-in computer module.

Is the camera included with the panel?

No. The 4K camera with a 120° field of view and 15° tilt adjustment is an optional add-on, so it is not part of the standard panel. If your room needs camera-based video conferencing, say so when you request a quote so the team can confirm whether the camera is included and how it will be mounted. The two built-in 20W speakers are separate from the camera.

Can it be wall-mounted in a large logistics office in the Industrial Area?

Yes. The panel is designed for wall mounting or an optional mobile stand. Net weight is 51.5 kg and gross weight is 64.5 kg, and the packed box measures 1859 × 1160 × 227 mm. Before drilling, book a free site survey to check the wall's load capacity, the fixing points and the 1735 × 1047 × 112 mm outline. Plan at least two people to lift the panel.

Does it work on Qatar's 240 V supply?

The specifications give a working voltage of AC 100–240 V with a rated current of 4.5 A, and that range includes 240 V. Standby consumption is below 0.5 W. The source data does not state maximum power consumption, so ask for that figure before planning electrical circuits. Ask the SmartRooms Qatar team to confirm the plug type in your quotation.

Can it run in a hot lobby or an unair-conditioned area in summer?

No. The operating range is 0 to 40°C at 20% to 80% relative humidity, non-condensing, and storage is rated from -10 to 45°C. Outdoor temperatures in Qatar can exceed 45°C in summer, so a lobby next to a glass façade or a store room without cooling is unsuitable. Keep the panel in an air-conditioned room and confirm the installation environment with the SmartRooms Qatar team before work starts.

Can a school order several units on a purchase order?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and payment by bank transfer, cheque or purchase order. For a school fitting out several classrooms, send the quantity, a room list and the mounting type with your request. Quotations usually arrive within one working day. Because this model is discontinued, the quotation will be for a current equivalent or compatible replacement.
