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

Overview

The Newline 55-inch STV is a non-touch 4K LCD display with a 1mm bezel, HDR and a 178-degree viewing angle. It runs Android 11 and supports wireless casting from Windows, Mac, Android and iPhone devices. Its 1210 x 680 mm display area suits meeting rooms, classrooms and reception areas in Doha, West Bay and Education City where content and presentations share one screen.

What the Newline 55-inch STV is built to do

The Newline 55-inch STV is a non-touch commercial display built around a 55-inch LCD panel with 3840 x 2160 (4K) resolution. It is intended for showing presentations, meeting content and announcements rather than writing directly on the glass, so the focus is a clear picture and simple daily use. Its 1210 x 680 mm display area and frame of up to 1mm give a large image in a compact footprint, and its 10.9 kg net weight keeps it lighter than the larger models in the STV range.

The specifications that matter for a buyer

The panel is rated at 260 cd/m2 brightness, a 4000:1 contrast ratio, a 6.5 ms response time and a 60 Hz refresh rate, with a 178-degree viewing angle so people standing to the side can still read the screen. HDR support adds depth to video. The unit runs Android 11 with 2GB RAM and 16GB storage, and includes Wi-Fi 5.0 and Bluetooth. Two 10 W speakers are built in. Standard-mode power consumption is listed at 140 W, and standby is below 0.5 W.

Connectivity centres on HDMI 2.0 inputs supporting 4K at 60 Hz, with HDMI signal detection that switches sources automatically. Staff can open Word, spreadsheet and embedded document files directly from a USB flash drive, so a presentation can run without a laptop. Wireless casting covers Windows, Mac, Android and iPhone devices, and Newline Cast+ and VCS are listed as compatible software for managing signage.

Where it fits in Qatar

Meeting rooms in West Bay or Lusail: a 55-inch panel suits a mid-sized meeting room, and wireless casting from a laptop or phone removes cables from the table.
Classrooms in Education City or Al Wakrah: teachers can show files from a USB drive and cast from tablets without an extra media player.
Reception areas and corridors in hotels, clinics and malls: the screen can show digital signage for visitors, with announcements broadcast through VCS.

What to plan before ordering

Check the wall before mounting. The VESA pattern is 400 x 300 mm and the net weight is 10.9 kg without a bracket. SmartRooms Qatar offers free site surveys to confirm wall type, bracket and cable routing before installation. The source data does not give an operating temperature range for this model, so confirm the environment with the SmartRooms Qatar team before placing it near windows, in direct sunlight or in a dusty lobby where summer heat above 45 degrees Celsius is a concern. Also confirm power arrangements, since the supply voltage is not listed for this model.

Institutions buying several units can raise a purchase order (LPO) or take part in government tenders, and payment is accepted by bank transfer, cheque or purchase order. Delivery covers all eight municipalities of Qatar, and quotations are usually issued within one working day.

To request a quote for the Newline 55-inch STV, share the number of units, the room types and any mounting constraints, and the SmartRooms Qatar team will send a formal quotation.

Questions about 55" STV

What is the Newline 55-inch STV best used for?

The Newline 55-inch STV is a 4K LCD commercial display for presentations, meeting content and digital signage in rooms where a 55-inch screen is the right size. It suits a meeting room or classroom for a small to medium group, and a clinic or hotel reception where visitors need to read announcements from a few metres away. Its 178-degree viewing angle keeps the picture readable for people standing to the side.

Is the 55-inch STV a touch screen?

No. The STV is a non-touch display, so you control it with the remote control, which includes an air mouse function, or by casting from a laptop, phone or USB device. If your teaching or meetings depend on writing directly on the screen, an interactive touch panel is the better choice. For presentations, file sharing and signage, the non-touch design keeps the set-up simpler for busy Doha offices.

What resolution and picture quality does it offer?

The panel delivers 3840 x 2160 (4K) resolution across a 1210 x 680 mm display area, with HDR support, 260 cd/m2 brightness, a 4000:1 contrast ratio and 1.07 billion colours. The 6.5 ms response time and 60 Hz refresh rate suit video and moving content. In a lecture room at Education City, these figures keep slides and video clear for students seated towards the back.

How does wireless casting work?

The STV supports wireless casting from Windows, Mac, Android and iPhone devices, using the Newline Cast+ software listed as compatible with the series. A presenter can share a screen without cables, which helps when a team in Doha needs to show content to colleagues joining from abroad. Before installation, ask the SmartRooms Qatar team to confirm the network requirements your IT department needs to set up.

Can staff show files without bringing a laptop?

Yes. The STV can open Word, spreadsheet and embedded document files from a USB flash drive, and it runs Android 11 with productivity apps already installed. This suits a school in Al Rayyan where a teacher carries lesson files on a memory stick, or a government office in Msheireb that wants to show a document during a meeting. Check the file formats your team uses before the site survey.

What connections does it have?

The rear connections listed for the series include HDMI 2.0 inputs that support 4K at 60 Hz, and the STV uses HDMI signal detection to switch sources automatically. The data does not confirm the full rear port layout for this specific 55-inch model, so ask SmartRooms Qatar to check the exact ports against the manufacturer's current datasheet before ordering, especially if you need several inputs or a LAN connection.

How much power does it use and how heavy is it?

Standard-mode power consumption is listed at 140 W, and standby is below 0.5 W, which helps when comparing running costs across several screens. The net weight is 10.9 kg, lighter than the 65-inch and larger STV models. The supply voltage is not listed in the data for this model, so confirm local power arrangements with the team before installation, particularly for a wall-mounted display in a meeting room.

Can it be wall-mounted?

Yes. The VESA mount pattern is 400 x 300 mm and the net weight is 10.9 kg, so the starting point is a wall bracket rated for that load. Before drilling, the free site survey from SmartRooms Qatar checks the wall construction, the fixing method and the cable route. Professional installation can then follow the approved quotation, which is useful for a boardroom or lobby wall where appearance matters.

Will it work in a hot or outdoor area such as a covered entrance?

The source data does not give an operating temperature range or an outdoor rating for this model, so SmartRooms Qatar cannot confirm outdoor use. For a shaded lobby or an indoor room in Doha, the team can review ventilation and temperature during the site survey. Where summer heat above 45 degrees Celsius or dust is a risk, ask the team to recommend a suitable alternative after checking the specifications.

How is it used for digital signage?

The STV is compatible with Newline VCS, a digital broadcast network that sends messages straight to the panel without a separate media player. A hospital in Al Khor could display visitor information at reception, or a retail unit in The Pearl could show rotating in-store messages. Decide in advance who will manage the content and how often it changes, so the screen is set up for its purpose from day one.

Does the purchase include a warranty?

The STV is covered by the manufacturer's warranty. The source data does not state the warranty length or its terms, so ask SmartRooms Qatar to provide the warranty conditions in writing when you request a quote, and keep them with your asset records for the unit.

How should a school or university order several units?

Schools and universities in Qatar can request one quotation covering several 55-inch units, then raise a purchase order (LPO) against it. Payment by bank transfer, cheque or purchase order is accepted. Before ordering, list the room types, the number of units and any wall constraints, so the quotation reflects each room. Quotations are usually issued within one working day.
