A 75-inch 4K panel for mid-size teaching and meeting rooms

The Newline TT-7521Q is the 75-inch member of the Q Series, with an active screen and a display area of 1650 × 928 mm. Its 3840 × 2160 (4K) LED-backlit panel is rated at 400 cd/m2 brightness with a 5000:1 dynamic contrast ratio and a 178° viewing angle, so people at the edges of a room see the same clear picture as those in the centre. The panel offers 1.07 billion colours and an 8 ms typical response time.

Touch is handled by infrared sensing with 20 touch points, so several people can write or annotate at the same time. The anti-glare, anti-fingerprint surface keeps the image readable under bright ceiling lights and reduces smudging from frequent use.

One cable for laptops, PCs and room control

The panel has three HDMI 2.0 inputs, one DisplayPort 1.2 input, one HDMI 2.0 output for a second display and an RS-232 control input for room automation. A USB Type-C port with 65W power delivery carries data, audio, video and charging from a compatible laptop over a single cable, which keeps desks and front-of-room cabling tidy. Four USB Type-B touch connections, three USB 3.0 Type-A ports and RJ-45 network connections in and out complete the links. An OPS-PC slot accepts a plug-in computer module if you want a computer built into the panel rather than beside it.

Where the TT-7521Q fits in Qatar

Upper-year classrooms in Al Wakrah: A private school fitting out new classrooms for older students can use the 75-inch screen where pupils sit further from the board. Teachers connect one cable at the start of each lesson, and the built-in app store offers education tools without a separate PC.

Hybrid meeting rooms in West Bay: A company running meetings with colleagues abroad can show shared content at 4K resolution, with Wi-Fi 6 or a wired RJ-45 connection keeping the room online.

Technical training in the Industrial Area: A training centre can use the infrared touch and passive pen to mark up diagrams during a session, and the wide viewing angle helps trainees at the sides of the room read fine detail.

What to plan before you order

At 1735 × 1051 × 122 mm, the TT-7521Q is a large panel, so the wall, mounting hardware and delivery route should be checked before installation. SmartRooms Qatar offers a free site survey, and the wall-mounting or optional mobile stand can be confirmed for your room during that visit.

Plan the environment too. The rated operating range is 0°C to 40°C, and summer temperatures above 45°C outside mean the panel belongs in an air-conditioned room. The electrical contractor should confirm the socket and cable arrangement on site.

Schools, government bodies and companies can order by purchase order or LPO, and tender purchases through Monaqasat are supported. Request a quote and the SmartRooms Qatar team will return a detailed proposal, usually within one working day.

Questions about TT-7521Q

Is the TT-7521Q right for a classroom in Al Wakrah?

Yes, for upper-year and mid-size classrooms where students sit several metres from the board. The 75-inch screen has a 1650 × 928 mm display area, and the 178° viewing angle keeps text readable from side seats. A private school fitting out new rooms can connect a laptop with one USB-C cable, so lessons start quickly. For very large halls, the 86-inch model is the better fit.

How does the TT-7521Q differ from the 65-inch and 86-inch models?

It sits between them. The 65-inch TT-6521Q has a narrower display area and a lower weight, while the TT-8621Q offers 1895 × 1066 mm. The TT-7521Q's 1650 × 928 mm display area suits a classroom or meeting room that is too large for 65 inches but does not need an 86-inch lecture-hall screen. All three share 4K resolution, infrared touch and Android 11.

What touch technology does it use, and how many people can write at once?

The panel uses infrared touch with 20 touch points, so several users can write or annotate together. It accepts a passive pen as well as fingers. The anti-glare, anti-fingerprint surface has 88% ±3 touch transparency, and the glass is rated 7H on the Mohs scale. If your trainees take turns at the board, confirm your usage pattern with the SmartRooms Qatar team when requesting a quote.

Which ports does the TT-7521Q have for laptops and PCs?

It has three HDMI 2.0 inputs, one DisplayPort 1.2 input, one HDMI 2.0 output, one USB Type-C port with 65W power delivery, one USB 3.0 Type-C port without power delivery, four USB Type-B touch ports, three USB 3.0 Type-A ports and an OPS-PC slot. Audio connections include a microphone input, a line output and S/PDIF. Networking is RJ-45 in and out, and the RS-232 input supports room control.

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

Yes, if the laptop supports USB-C video input and power delivery. The Type-C port is rated at 65W and carries data, audio, video and power over one cable, so a compatible laptop charges while connected. For a West Bay boardroom running meetings with colleagues abroad, this means fewer cables on the table. Wireless connection is also available through Wi-Fi 6 and Bluetooth 5.2.

What power supply does it need, and does it suit Qatar's 240V mains?

The TT-7521Q lists an AC input range of 100 to 240V with a maximum current of 6.2A, and a rated power consumption of 240W. The 240V end of that range matches Qatar's mains supply, which is 240V at 50 Hz. Your electrical contractor should confirm the socket and circuit on site, because the source data does not describe a plug type.

Can it be wall-mounted, and what should we check before delivery?

The TT-7521Q supports wall mounting, and a mobile stand is available as an option. Its outline is 1735 × 1051 × 122 mm, so measure the wall and the route to the room first. SmartRooms Qatar offers a free site survey to check wall structure, viewing height and the lifting route before installation. Delivery covers all eight municipalities of Qatar, and installation can be arranged with your quotation.

Can the panel be used in a hotel conference room in The Pearl during summer?

Yes, in an air-conditioned conference room, but not in an unconditioned space. The rated operating range is 0°C to 40°C with 20% to 80% humidity, non-condensing. Summer temperatures in Doha can exceed 45°C outdoors, so keep the panel inside a cooled room away from direct sun through large windows. Ask SmartRooms Qatar to confirm the room environment during the site survey before you order.

Is it suitable for technical training in the Industrial Area?

It can be, for sessions that use the screen as a shared whiteboard or display. The infrared touch supports 20 points, and the passive pen lets an instructor mark up drawings or diagrams. The 4K resolution helps present detailed schematics, and the 178° viewing angle keeps them readable from the back row. Keep it in a clean, climate-controlled training room, since the rated operating range is 0°C to 40°C.

Does the TT-7521Q suit a ministry office where staff work in Arabic and English?

Language support is a question to confirm before ordering, because the source data does not list language options for the on-screen menus or the Android interface. The Android 11 platform, app store and user profiles let each staff member save their own home screen and settings. For an office in Msheireb, the SmartRooms Qatar team can answer the language question during the quotation stage.

What health features does it have, and are they certified?

The screen uses an antimicrobial tempered glass surface, which Newline describes as TÜV certified. Its LED backlight uses a KSF phosphor layer to filter blue light at the source, and Newline states that the low blue light feature carries TÜV Rheinland certification. The Q Series also offers 85% NTSC colour coverage. For schools where many pupils share a board, these features suit everyday use.

How do we order several units for a school through an LPO or Monaqasat tender?

SmartRooms Qatar supplies the TT-7521Q against purchase orders (LPOs) and government tenders, including Monaqasat. For a school ordering several panels, send the quantity, the room list and delivery addresses with your request. A quotation is usually issued within one working day. Payment is by bank transfer, cheque or purchase order, and installation can be included in the quotation.
