WA75D

What the WA75D is built for in a 75-inch room

The Samsung WA75D is a 75-inch interactive display from the WAD series, made for teaching and meeting rooms that need one large surface for writing, annotating and presenting. Its 3,840 x 2,160 panel delivers 4K detail, so spreadsheets, maps and small print stay sharp from the back row. At 1709 x 1020 x 88 mm, its slim body suits wall mounting and keeps floor space free for seating.

Panel, touch and pen performance that matter in use

The ADS panel is rated at 400 nit typical brightness with a 1,200:1 contrast ratio and 178/178 viewing angles, so people seated off-centre still see accurate colour. The 8 ms response time keeps handwriting and moving content smooth. Colour gamut is specified at 72%, and the 25% glass haze value means the front surface diffuses light to soften reflections from windows and ceiling lights.

The infrared touch layer registers up to 40 simultaneous touchpoints, so several students can work on the board at the same time. A dual pen function uses a double-sided nib, letting a teacher switch between two ink colours on the front and back of the pen without opening the settings menu.

Android 13, ports and wireless sharing

The WA75D runs Android 13 with 64GB of flash memory. Its EDLA certification supports Google services such as Google Play and YouTube, and split-screen and multi-window modes let teachers work across two apps at once. An OPS slot can turn the display into a Windows device, so a separate classroom PC is not always needed.

Ports cover most room setups: three HDMI inputs (HDMI version 2 with HDCP 2.1), 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 65W, RS232 and RJ45 in and out, plus Wi-Fi and Bluetooth. Screen mirroring supports up to nine devices, and video output can send whiteboard content to a larger screen.

Planning a WA75D installation in Qatar

The WA75D is rated for operating temperatures of 0 to 40 degrees Celsius and 10 to 90% humidity, so it belongs in an air-conditioned room. Qatar summers can exceed 45 degrees Celsius, so do not site it in corridors without cooling, outdoor canopies or rooms with direct afternoon sun and no climate control. Confirm the room environment with the SmartRooms Qatar team before fixing the unit.

Plan these points before installation:

• Wall structure: the set weighs 45.5 kg and ships at 57.6 kg, so confirm fixings and handling.
• Bracket: the VESA pattern is 800 x 400 mm, so the wall mount must match it.
• Access: check lifts and doorways for the 1863 x 1140 x 225 mm package.
• Power: the supply is rated 100 to 240V, 50/60Hz, drawing 385W in on mode and 0.5W in sleep mode.

Where the WA75D fits across Qatar

A private school classroom in Al Wakrah replacing an older whiteboard can use the touch surface for group work and Android apps, while the OPS slot can host Windows software that some subjects still need. A meeting room in West Bay can display presentations from several laptops through screen mirroring, with blinds drawn during the afternoon. A training room in Lusail benefits from multi-touch when several participants annotate the same document in a workshop.
