Brand: Newline
SKU: newline-stv-plus-55
Availability: InStock

Overview

The Newline 55-inch STV+ is a non-touch 4K UHD commercial display with embedded Android 14, 300 cd/m² brightness and 24/7 operating time. Wake-on-LAN, Wake-on-WiFi and IP control let facilities teams power it on remotely and schedule it. It suits mid-sized meeting rooms, classrooms and reception areas in Doha, Lusail and Al Rayyan, and its 400 x 300 mm VESA pattern and 10.8 kg net weight make wall mounting practical.

What the Newline 55-inch STV+ is built for

The Newline 55-inch STV+ is a non-touch commercial display from the STV+ Series, built for organisations that want one screen to handle presentations, internal announcements and digital signage. Its 4K UHD panel offers a 1210 x 680 mm display area in a 16:9 format, and it runs embedded Android 14 with 4 GB of RAM and 16 GB of storage, so apps and playlists can run without an external media player.

This is a commercial model rather than a home television. The manufacturer specifies 24/7 operating time, which matters in a school corridor, a hotel lobby or a reception desk where the screen is expected to stay on through the working day.

Where it fits in Qatar

In a private school in Al Wakrah fitting out a new science wing, the 55-inch size suits classrooms and labs where a single screen must be clear without the cost and wall load of a larger panel. RS232 and IP control let the school's maintenance team switch the screen on and off to match the timetable.

In a clinic or corporate reception in West Bay, the same size works for wayfinding, appointment boards and visitor information. Wake-on-LAN and Wake-on-WiFi allow the display to be woken remotely so it is ready when the day starts. In a government office in Msheireb, it can serve a meeting room where teams work in Arabic and English side by side, with Cast+ letting presenters share from Windows, Mac, Android or iPhone devices.

What to plan before ordering

Check the wall structure and bracket against the 10.8 kg net weight and 400 x 300 mm VESA pattern.
Keep the screen in indoor, air-conditioned spaces. The operating range is 0 to 40°C, while Qatar summer temperatures outdoors regularly exceed 45°C.
The power input is rated 100-240 V, 50/60 Hz, which covers Qatar's 240 V, 50 Hz supply. Confirm the power cord for your region in the quotation.
Decide how content will be managed through Signage Pro, Display Management Plus or Cast+.

SmartRooms Qatar offers a free site survey before wall mounting, delivery to all eight municipalities of Qatar and professional installation. Request a quote and we will return the configuration, accessories and mounting details with it, usually within one working day.

Questions about 55" STV+

What is the Newline 55-inch STV+ best suited for?

It suits mid-sized meeting rooms, classrooms, reception areas and corridors where one 4K display must handle presentations and announcements. Its 1210 x 680 mm display area and 16:9 format work well in a room where people sit a few metres from the screen. The 24/7 operating time means it can run signage through the working day.

How does the 55-inch model compare with the 43-inch and 65-inch STV+?

The 55-inch sits between them. Its display area is 1210 x 680 mm, against 941 x 529 mm for the 43-inch and 1428 x 804 mm for the 65-inch. It weighs 10.8 kg net, compared with 6.4 kg and 16.3 kg, and uses a 400 x 300 mm VESA pattern. Choose it when 43 inches feels small and 65 inches is too large for the wall.

Can I install it in an outdoor area, a sun-facing lobby or an unconditioned store in Qatar?

No. The manufacturer specifies an operating range of 0 to 40°C, and Qatar summer temperatures outdoors regularly exceed 45°C. Install it indoors in air-conditioned spaces, away from direct sunlight through windows. If you are unsure about a particular space, send us the details and we will review it before you order.

What wall mount and space do I need?

The panel uses a 400 x 300 mm VESA pattern and weighs 10.8 kg net, so the bracket must match both. The outline is approximately 1226 x 709 mm. Book a free site survey so we can check the wall structure, cable routing and viewing height before any drilling starts, especially in a school or office with busy corridors.

Does it need an external media player?

Not for basic signage. It runs embedded Android 14 with 4 GB RAM and 16 GB storage. Content can be managed through Signage Pro and the Display Management Plus web portal, and Cast+ lets people share screens from Windows, Mac, Android and iPhone. Check large multi-zone layouts with our team against the storage size before ordering.

Which ports and inputs does it provide?

It has three HDMI inputs, USB-A 3.0 and USB-A 2.0 ports, an RJ45 LAN input, an RS232 port and an AV input. Audio leaves through a line out and an S/PDIF out. Wireless connectivity is Wi-Fi 5 and Bluetooth 5.0. In a meeting room, the HDMI inputs can take a laptop and a separate source, such as a conferencing device, at the same time.

Can facilities staff control it remotely and on a schedule?

Yes. Wake-on-LAN and Wake-on-WiFi let the display be powered on remotely, while IP control and RS232 support integration with room or building systems. Auto Power On/Off sets scheduled times so the screen is ready when staff arrive. Fast Boot mode is listed at about 2 seconds to power up.

Is the built-in sound enough for a large room?

The display has two 15 W speakers in a 2.0 layout, positioned at the rear. That suits a classroom or small meeting room. For a lecture hall, a large atrium or an event space in Education City, plan external audio connected through the line out or S/PDIF out, and confirm the set-up with our team.

Is it suitable for a school ordering several units?

Yes. A school in Al Rayyan or Education City can order several 55-inch panels under one LPO. SmartRooms Qatar usually issues quotations within one working day, delivers to all eight municipalities of Qatar and accepts bank transfer, cheque or purchase order. Ask for one quotation that covers the mounting accessories for every room.

Will it work with Qatar's electricity supply?

The power input is listed as 100 to 240 V, 50/60 Hz, with a maximum current of 2.0 A for the 55-inch model. Qatar's 240 V, 50 Hz supply falls within that range. The power cord is supplied by region, so confirm the plug type for Qatar's BS 1363 sockets in your quotation before the panels arrive.

What warranty applies to this model?

The product is covered by the manufacturer's warranty. The warranty period and terms are confirmed with your quotation, so you know exactly what applies before you place a purchase order. If your organisation needs written terms for a tender or LPO file, mention this when you request the quote.

What comes in the box?

The listed accessories are a power cord for the region, a remote control, AAA batteries for the remote and an AV adapter. Check the accessory list on your quotation for any mounting hardware you need, because the bracket requirements depend on your wall and the VESA pattern of 400 x 300 mm.
