Samsung 75" WAF 4K Interactive Whiteboard, EDLA Certified, LH75WAFWLGCXZA

The Samsung 75" WAF Interactive Whiteboard turns a classroom or meeting room into a shared workspace. The 75-inch 4K touchscreen reads up to 40 points of contact at once, and EDLA certification means Google Workspace, Chrome and the Play Store run on the screen itself with no computer attached.

75-inch 4K UHD IPS touchscreen

At 75 inches, 4K resolution keeps normal text readable from the back of a classroom or across a conference table. The IPS panel holds color and contrast at 178 degrees in both directions, so people sitting at the sides see the same picture as the person standing at the board. A 25% haze finish cuts reflections from overhead lighting.

• 3840 x 2160 (4K UHD) resolution
• IPS panel, 178 / 178 degree viewing angle
• 400 nits brightness, 1200:1 contrast
• 8ms response, 60Hz
• 72% color gamut, 25% haze anti-glare finish
• Rated for 12 hours a day, 7 days a week

EDLA certified, running Android 14

EDLA is Google's certification for interactive displays. It means Google Workspace, Google Classroom, Chrome, YouTube and the Play Store are licensed to run natively on this screen. Staff sign in with the accounts they already use. The home screen is customizable, so a school can put the apps teachers actually use front and center.

40-point touch, dual pen, and four note zones

Infrared touch tracks up to 40 contact points at the same time. The dual pen has a double-sided nib, so one person switches between two colors without picking up a second pen.

Split Note Mode gives up to four independent note zones on one page, so four groups can work side by side on the same screen. Annotation is always available from a single button press, over anything on screen.

Wireless sharing for up to nine devices

Smart wireless sharing supports screen mirroring from up to nine devices. Students and staff cast from phones, tablets and laptops with no cable and no adapter, and the teacher switches between them.

One USB-C cable for a laptop

The 3-in-1 USB-C port carries video, touch control and up to 65W of power over a single cable. A presenter plugs in once: their screen appears, the touchscreen drives their laptop, and the laptop charges while they present. For rooms that need full Windows, the OPS slot takes a Windows module that slides into the back.

Connections

• 2 x HDMI 2.1 in (HDCP 2.1)
• HDMI out

• 4 x USB

• RS232 in for AV control systems
• Stereo mini jack in and out
• Wi-Fi 5 (802.11ac) and Bluetooth

Front-facing physical controls give quick access to the functions people use most, without digging through a menu.

Built for schools and campuses

Advanced messaging pushes urgent communications to every whiteboard across classrooms, campuses and public spaces at once. Remote device management lets IT control whiteboard settings and applications without visiting each room. The WAF series also protects against electrical surges and is built to handle humid climates.

Mounting and installation

The display uses an 800 x 400 mm VESA pattern. Note this differs from the 65 inch (600 x 400) and the 86 inch (800 x 600), so brackets are not interchangeable across the range. At 108.5 lb it needs a wall mount or mobile stand rated for that weight and a two-person installation. No stand is included. The carton weighs 127.60 lb and ships by freight, so plan for liftgate delivery and someone on site to receive it.

Up to 40 touch points at the same time, with Split Note Mode giving four independent note zones on one page.
