Six decisions that determine whether the display is used in every lesson or becomes an expensive screen for slides.
1. A screen size that fits the room
The most common mistake is a screen that is too small. What counts is the distance from the board to the back row: up to 5 m, 65 inch is enough; up to 6.5 m – 75 inch; up to 8 m – 86 inch. Auditoriums need 98–110 inch. Details in the guide Which screen size to choose.
2. Operating system and apps
Choose a model with Android 13 or later or with Google EDLA certification – teachers then get the Play Store, Classroom and Drive without an extra computer. Add an OPS computer with Windows only if the school uses desktop software.
3. Touch and writing
20 touch points let several students work at the board at the same time. The smaller the gap between the glass and the panel (zero bonding), the more natural writing feels.
4. Brightness and glass
Sunny rooms need 450–500 cd/m² and anti-glare glass. Tempered glass protects the screen from damage.
5. Warranty and service
A school display runs several hours a day for many years. Look for a warranty of at least 3 years, ideally with on-site service. Some manufacturers offer 5 or even 8 years.
6. Installation and 0% VAT
The display can be wall-mounted or placed on a mobile stand or lift. Schools buy displays and OPS computers at the 0% VAT rate, and public institutions pay within 14 days.
