How to choose an interactive screen

Step 1 · Define the classroom context

Before requesting quotes, define where the screen will go: classroom size, distance of the farthest student, ambient light and the intended pedagogical use. This data prevents comparing equipment that is not comparable.

Step 2 · Evaluate the five key criteria

Five factors determine whether a screen will actually serve in the classroom:

• Size: between 65" and 86" depending on the viewing distance.
• Touch technology: precision and number of simultaneous touch points.
• Brightness: enough to be seen in ambient light.
• Included software: which platform and content it ships with.
• After-sales support: warranty, spare parts and response times.

Step 3 · Ask the supplier these questions

The right questions reveal differences that spec sheets hide:

• Does the screen work without internet?
• What software and content does it include, and is there a recurring cost?
• What is the warranty and the support response time?
• Are there spare parts and technical service in the country?
• Does it include teacher training?

Step 4 · Avoid the most costly mistakes

The most common mistakes are buying on price alone, ignoring the total cost of ownership — which includes maintenance and software over the whole lifespan — and leaving out teacher training. A screen without trained teachers ends up underused.
