Glass hardness of 7H or above — the highest in the family, and the specification that matters most where dozens of students use the device daily. Twenty touch points let several students write together, and a PET-tipped stylus is designed for teaching, with an anti-slip body and magnetic attachment.
A three-part eye protection package: optical (not software) anti-blue light, an anti-glare surface, and adaptive brightness that adjusts to classroom lighting. It holds two TÜV Rheinland certifications — low blue light and eye comfort. Saudi education tenders ask for these explicitly.
The panel is 4K with 10-bit colour depth (8-bit + FRC) for 1.07 billion colours, 350 nits, 1200:1 contrast, 178° viewing angle and 60 Hz refresh.
Writing latency is 25 ms with ±1 mm precision — higher than the 16 ms of newer models, a difference noticeable during sustained fast writing, and the first consideration when comparing against the Board 3 Pro.
