What the Samsung WA75C is built for

The Samsung WA75C is a 75-inch interactive display from the WAC series, sold under the ordering code LH75WACWLGCXUE. It pairs a large touch-enabled panel with the Android 11 operating system, so teachers and presenters can run apps and lesson content directly on the screen without a separate computer. It is intended for classrooms, training rooms and boardrooms where a whole group needs to see the same surface and write on it together.

Panel, touch and writing

Resolution: 3,840 x 2,160 pixels on an ADS panel, with 400 nit typical brightness and a 1,200:1 contrast ratio.
Touch: infrared touch technology supporting up to 40 simultaneous touchpoints, so several people can write or draw at once.
Dual pen: two writing colours in one pen, switched between the front and back nib without changing settings.
Visual performance: 8 ms response time, 178/178 viewing angles and a 72% colour gamut.

The glass haze rating is 25% and the frame has a non-glossy finish. Plan lighting and seating around the panel in rooms with strong daylight, so the display stays easy to read from the back of the room.

Android, sharing and multitasking

Android 11 and 32 GB of flash memory allow frequently used apps to be pinned to the home screen, and built-in timers and stopwatches help pace a lesson. Split-screen and multi-window modes show several sources side by side. Up to nine devices can share screens at the same time, with content moving both ways between the display and individual devices. Sharing works from iOS, Mac, Windows, Android and Chrome OS devices that meet the minimum versions the manufacturer specifies. A front-facing built-in speaker keeps sound close to the presenter.

Connections, control and room integration

Three HDMI inputs (HDMI 2, HDCP 2.1) and an HDMI output that copies whiteboard content to a larger screen in the room.
Five USB ports: one USB 2.0 and four USB 3.0.
A 3-in-1 USB-C port for screen mirroring, touch control and charging external devices at up to 65 W.
RS232 and RJ45 connections for input and output, an IR input, and Wi-Fi and Bluetooth for control and networking.

Where it fits in Qatar

In a secondary school in Al Rayyan, a 75-inch panel gives students at the back of a classroom a readable display for lessons and shared group work. In a Lusail office, a laptop connected to one of the HDMI inputs can show a video call with teams abroad, while participants annotate shared documents on the same screen. At a training centre in Education City, instructors can share from several devices at once, so each trainee presents from their own laptop without swapping cables.

Planning the installation

The set measures 1,709 x 1,020 x 88 mm and weighs 45.5 kg, and its VESA pattern is 800 x 400 mm. The bezel is 16.4 mm at the top and sides and 44.9 mm at the bottom. The operating range is 0 to 40°C at 10 to 90% humidity, so the panel belongs in an air-conditioned room away from direct sun, not in an unconditioned lobby. The packed unit weighs 57.6 kg, so plan delivery access and check the wall before ordering. Power draw is 385 W in use and 0.5 W in sleep mode, on a 100-240V, 50/60Hz supply. SmartRooms Qatar offers free site surveys and professional installation, and we recommend a survey before wall-mounting a panel of this size.

Questions about WA75C

Who is the Samsung WA75C built for?

It suits organisations that need one large touch surface for a whole group, such as schools, universities, training centres and corporate meeting rooms. The 75-inch panel gives a full classroom or boardroom a clear view, while 40-point touch and the Android 11 platform let presenters run apps and lessons without a separate computer. If you are weighing it against a smaller panel for a compact room, send us the room dimensions and we will advise.

Will the WA75C cope with a hot classroom in Doha during summer?

Not in an unconditioned space. The panel's operating range is 0 to 40°C at 10 to 90% humidity, and summer temperatures in Qatar can exceed 45°C. Install it in an air-conditioned room, keep it away from direct sunlight through large windows, and confirm the room conditions with the SmartRooms Qatar team before you commit to a location.

Can several students write on the screen at the same time?

Yes. The infrared touch supports up to 40 simultaneous touchpoints, so groups can work on a shared problem at the board. The dual pen gives each person two colours, switched between the front and back nib without changing settings. In a secondary school in Al Rayyan, a maths group can solve a problem together while the rest of the class follows on the same panel.

How many devices can share their screens to the WA75C?

Up to nine screens can be shared at the same time, and content can move both ways between the panel and individual devices. Sharing works from iOS 10.0 and higher, Mac OS X 10.11 and higher, Windows 10 and higher, Chrome 38 and higher, and Android 5.1 and higher. For a training room in Education City, that means several participants can present from their own laptops or phones without cables.

What inputs does it have for laptops and other sources?

The WA75C has three HDMI inputs using HDMI 2 with HDCP 2.1, plus a 3-in-1 USB-C port that handles screen mirroring, touch control and charging of external devices at up to 65 W. It also has five USB ports, one USB 2.0 and four USB 3.0, along with stereo mini jack audio in and out. This covers a laptop, a document camera and a second source in the same room.

Can the panel be controlled from a room system or connected to a network?

It offers RS232 and RJ45 connections for input and output, plus an IR input, which allow it to be controlled and networked as part of a wider room system. It also includes Wi-Fi and Bluetooth. Whether it works with a specific control system or conferencing codec depends on that equipment, so send the details of your current system with your quotation request and we will confirm compatibility.

Will it work for a meeting room in Lusail that connects to teams abroad?

A Lusail office calling teams abroad can connect a laptop to one of the HDMI inputs and show the video call and shared documents on the 75-inch panel. Its touch function lets participants annotate the same document in real time. The camera and microphone are separate equipment, so tell us what you already use when you request a quote.

How much wall space and load does the WA75C need?

The set measures 1,709 x 1,020 x 88 mm and weighs 45.5 kg, and it mounts to a VESA pattern of 800 x 400 mm. The packed unit weighs 57.6 kg and measures 1,863 x 1,140 x 225 mm, so plan delivery access and a wall that can carry the load. SmartRooms Qatar offers free site surveys, which we recommend before wall-mounting a panel this size in a boardroom or school hall.

What power does the WA75C draw?

It draws 385 W in on mode and 0.5 W in sleep mode. The power supply is rated for AC 100-240V at 50/60Hz, which covers Qatar's 240 V, 50 Hz mains. Operation time support is rated 16/7. In a school or office running the panel through the working week, sleep mode keeps idle draw low, and your quotation will confirm the plug and socket arrangements for your site.

Is the WA75C covered by warranty?

Products supplied by SmartRooms Qatar are covered by the manufacturer's warranty. The warranty terms are set by the manufacturer, and we will confirm the terms that apply to this model in your quotation before you commit to an order. Ask us for them alongside the delivery and installation details.

Can a government ministry or school buy it through an LPO or a Monaqasat tender?

Yes. SmartRooms Qatar works with purchase orders (LPOs) and government tenders, including those on Monaqasat, and accepts payment by bank transfer, cheque or purchase order. Quotations are usually issued within one working day. State the number of WA75C units and the delivery locations across the eight municipalities of Qatar when you request a quote.
