Newline I Series (Discontinued) · Replacements in Qatar

Name: Newline I Series 65, 75 and 85-inch Interactive Display
Brand: Newline
SKU: newline-i-series
Availability: Discontinued

Overview

The Newline I Series is a discontinued range of 4K interactive displays in 65, 75 and 85-inch sizes, covering models TT-6519I, TT-7519I and TT-8519IS. Each unit combines the panel, 20-point infrared touch, two 15 W speakers and an optional OPS PC slot, replacing a projector and whiteboard in one device. The manufacturer has discontinued this series, so SmartRooms Qatar quotes a current equivalent or compatible replacement for schools and offices in Qatar that need one.

The manufacturer has discontinued the Newline I Series. This page covers its three models, the TT-6519I (65-inch), TT-7519I (75-inch) and TT-8519IS (85-inch), for schools and offices that already run them, for buyers comparing them with other panels, and for anyone who needs a replacement.

Three sizes for different room depths

All three share a 16:9 4K UHD panel, and the active area grows with screen size. Match the size to the furthest seat from the screen.

TT-6519I: display area 1428 x 804 mm, net weight 44 kg.
TT-7519I: display area 1650 x 928 mm, net weight 57 kg.
TT-8519IS: display area 1872 x 1053 mm, net weight 69 kg.

Image, touch and sound figures

The panel resolves 3840 x 2160 pixels across a 178-degree viewing angle. Its anti-glare, tempered glass surface, rated above 7H, limits reflections from bright windows. The 65-inch model is rated at 370 nit and the 75-inch at 400 nit, with 4000:1 dynamic contrast. Infrared touch supports 20 points using a stylus or finger, and two 15 W speakers are built in.

Ports and software to plan for

The rear panel has two HDMI 2.0 inputs, a VGA input with audio, an AV output, an RS232 port and a 4K at 60Hz OPS slot for an optional PC module. The unit has no embedded operating system, so Windows runs from an external computer or the OPS PC. The free Teach Infinity II lesson software supports Windows, Mac and Linux.

Where it fits in Qatar

A primary school in Al Rayyan replacing a ceiling projector and worn whiteboard in each classroom with a 65-inch panel.
A lecture room in Education City where the 85-inch TT-8519IS keeps text readable for students in the back rows.
A training centre in the Industrial Area running staff induction sessions from one panel and one computer.

Planning power, heat and mounting

Rated input is 100 to 240 V AC. Maximum draw is 250 W on the 65-inch, 400 W on the 75-inch and 450 W on the 85-inch, with 0.5 W in standby. Operating range is 0 to 40 degrees Celsius. Qatar summers can pass 45 degrees, so place these panels in air-conditioned rooms rather than corridors or outdoor areas. Panels wall mount or sit on a mobile stand. The 85-inch model weighs 69 kg net, so a free site survey to check wall structure before installation is advisable.

Questions about I Series

Is the Newline I Series still sold new?

No. The manufacturer has discontinued the I Series, so SmartRooms Qatar cannot treat it as a current product line. If you already own a TT-6519I, TT-7519I or TT-8519IS and need a spare, or you are comparing options for a classroom, request a quote and we will confirm whether a current equivalent or a compatible replacement suits your room.

Which model suits my room: 65, 75 or 85 inches?

The 65-inch TT-6519I has a 1428 x 804 mm display area and suits a standard classroom or small meeting room. The 75-inch TT-7519I, at 1650 x 928 mm, fits larger rooms, while the 85-inch TT-8519IS, at 1872 x 1053 mm, suits lecture halls. Measure the furthest seat from the screen and the wall width before choosing.

How bright are the panels, and does the 85-inch model match the smaller ones?

The datasheet rates the 65-inch model at 370 nit and the 75-inch model at 400 nit, with a 4000:1 dynamic contrast ratio. It does not list a brightness figure for the 85-inch TT-8519IS, so ask us to confirm that figure before comparing it with the smaller models. The anti-glare surface also helps reduce reflections from windows.

How does the touch function work and how many touch points are supported?

The panel uses infrared touch with 20 touch points and accepts a stylus or a finger. Its surface is anti-glare tempered glass with a hardness above 7H. Manufacturer material for this series highlights that no calibration is required, which removes a routine step that projector-and-whiteboard setups need. Test the touch behaviour with your own lesson software before rollout.

Can these panels run in a classroom in Doha during the summer?

Yes, provided the room is air-conditioned. The working range is 0 to 40 degrees Celsius at 20 to 80 percent humidity, non-condensing, and the storage range is minus 10 to 45 degrees. Qatar summer temperatures can exceed 45 degrees, so keep the panel away from corridors, outdoor areas and windows that receive direct afternoon sun.

Our school in Al Rayyan is replacing projectors. What do we gain?

One panel replaces a projector, a whiteboard and a speaker set, because the I Series combines these functions in a single unit. The free Teach Infinity II lesson software supports Windows, Mac and Linux for lesson preparation. The 65-inch and 75-inch models suit typical classrooms, and you should check that the wall and existing cable routes suit a panel mount.

Does the I Series have its own operating system?

No. The datasheet lists no embedded operating system. Windows runs from an external computer connected to the panel, or from an optional built-in OPS PC that plugs into the OPS slot, which supports 4K at 60Hz. Specify the OPS PC option when you request your quotation so the figure is confirmed for your order.

Which ports and inputs does the panel provide?

The rear panel has two HDMI 2.0 inputs, a VGA input with audio, an AV output, an earphone output, a USB 2.0 port, an RS232 port and a touch USB Type B connection. The front includes an HDMI input, a touch USB Type B connection and a microphone input. Check the port layout for your specific model in the manual before planning cable runs.

Can the panel be wall mounted, and how heavy is it?

The panels can be wall mounted or used on a mobile stand, and VESA mounting is supported. Net weights are 44 kg, 57 kg and 69 kg for the 65-inch, 75-inch and 85-inch models, with packed gross weights of 58 kg, 73 kg and 86 kg. Before fixing an 85-inch unit, we carry out a free site survey to check the wall structure, fixings and cable route.

What power does it draw and what supply does it need?

The rated input is 100 to 240 V AC. Maximum draw is 250 W for the 65-inch, 400 W for the 75-inch and 450 W for the 85-inch, with 0.5 W in standby. These figures help you size the circuit and any UPS, and the installer should confirm the socket arrangement on site.

What suits a lecture hall at Education City?

The 85-inch TT-8519IS has a 1872 x 1053 mm display area at 3840 x 2160 pixels, so text and diagrams stay sharp for students in the back rows. The 178-degree viewing angle keeps the image readable from side seats, and two 15 W speakers provide enough sound for smaller rooms. Check the hall's acoustics before relying on built-in speakers in a large space.

Can a government entity buy this through an LPO or tender?

Yes. SmartRooms Qatar accepts purchase orders (LPOs) and government tenders, including Monaqasat, and payment by bank transfer, cheque or purchase order. Because this series is discontinued, the quotation will state whether the exact model or a compatible replacement is supplied. Multi-unit school orders can be quoted together in one document.
