WA75F

What the WA75F does in a teaching or meeting room

The Samsung WA75F combines a large 4K touch screen, annotation and an Android 14 operating system in one unit. It is built for rooms where a single screen takes over the jobs of a projector, a whiteboard and a presentation display, which simplifies both the equipment list and the cabling.

Annotation works on top of whatever is open. Teachers and presenters can write over a video, a web page or a shared document without capturing a screenshot first. The unit also carries EDLA certification, so it supports Google services such as Google Play and YouTube, and it can run education apps such as Google Classroom.

Display and touch figures that matter in daily use

The 75-inch IPS panel runs at 3,840 x 2,160 resolution with 400 nit typical brightness and a 1,200:1 contrast ratio. Its viewing angle is rated at 178 degrees both horizontally and vertically, so people seated towards the sides of a room still see the same content. The response time is 8 ms, the colour gamut is 72%, and the glass haze is 25%.

Touch is infrared and handles up to 40 simultaneous touchpoints, so several people can write or draw at once. Front-facing physical controls give quick access to frequently used functions, so the presenter does not need to walk back to a laptop for every change.

Connecting laptops, rooms and the network

There are two HDMI inputs running HDMI 2.1 with HDCP 2.1, four USB ports, and a 3-in-1 USB-C port that carries screen mirroring, touch control and charging for an external device at up to 65 W. An RS232 input supports control from a room system, an RJ45 port provides a wired network connection, and Wi-Fi 5 (802.11ac) and Bluetooth are built in. A video output lets the board content appear on a larger screen elsewhere in the room. Screen mirroring supports up to nine devices across iOS, macOS, Windows, Android and Chrome OS.

Where it fits in Qatar

• A private school in Al Wakrah equipping bilingual classrooms, where teachers move between English and Arabic lessons on one screen and students annotate shared texts.
• A ministry meeting room in Msheireb where officials connect over wired RJ45 or Wi-Fi and share documents from their own laptops during meetings with colleagues abroad.
• A training centre near Education City running small-group workshops, where up to four note zones let students work at the board at the same time.

Planning the wall, power and climate

At 49.2 kg, the set needs a wall, bracket and fixings rated for that full load. The mounting pattern is 800 x 400 mm VESA, and the set measures 1716.5 x 1031.9 x 87.7 mm with a 17.2 mm black aluminium bezel. The packed unit weighs 58.8 kg, so plan for two people and a clear delivery route to the room.

The power supply accepts AC 100-240V at 50/60 Hz, which covers Qatar's 240 V, 50 Hz mains. Power draw is 450 W in on mode and 0.5 W in sleep mode, with an energy efficiency rating of B. The stated operating range is 0°C to 40°C and 10 to 80% humidity, non-condensing. Qatar summer temperatures can exceed 45°C, so the unit belongs in an air-conditioned room kept within that range, not in an unshaded or outdoor space. Samsung also describes a glass fuse and a 500V DC capacitor for surge protection, based on its internal testing.

The set is certified to FCC CFR Title 47 Part 15 Subpart B and EN55032 for electromagnetic compatibility, and to IEC62368-1 for safety.
