Use a familiar lesson as the demonstration
Start with material teachers already know. That makes it easier to judge whether the display supports the lesson or adds setup work. Penthia’s Vertex lineup lists touch, whiteboard/annotation and screen sharing; the actual software and configuration determine the details.
These are suggested test sequences, not reports of measured outcomes from Penthia school deployments. Bring the lesson, the intended teacher device and an IT-approved test account to a demonstration.
Work through an example together
Open a mathematics problem or a text passage large enough to read from the last seat. Write one step or mark one phrase on the display, then move between the original content and the annotation. Ask another participant to continue.
- Can the intended users reach the controls and writing area?
- Does touch behave correctly in this application?
- Can accidental marks be undone without losing the worked example?
- Can the final annotated work be saved in a usable format?
A multi-touch specification does not tell you how many people can use every application simultaneously. Verify the software behavior for the activity.
Compare two approaches
Prepare two solutions, short passages or diagrams in the lesson software. Display them at a size students can read, then annotate the differences. Test this layout explicitly; placing more material on a large screen can still make individual text too small.
Ask a teacher to change the view during the lesson and return to the original material. Use the last-seat readability test while the real comparison is on screen.
Share student work with a clear handover
Use an approved sample rather than private student work during procurement. Connect a supported device, share the sample, discuss it and end the session. Then connect the next device.
Check who permits sharing, how a mistaken connection is stopped and whether the first device remains connected after handover. Do not assume wireless sharing supports every device, returns touch input or crosses the school’s network segments. The wireless-sharing checklist explains what to verify.
Capture a lesson without leaving an account behind
Save the annotated result to the school’s approved destination and reopen it on another authorized device. Confirm the file format, readability and any editing limitations. A screenshot may preserve an explanation but not the original editable objects.
At the end, sign out and inspect the normal next-user experience with IT. Check for saved files and active sessions without using real sensitive student records. Decide who owns the cleanup procedure before a shared display enters service.
Choose a model after the test
Record which configuration ran the lesson, how it was connected and what did not work. Vertex Standard is the essential starting point; Pro adds publicly listed configuration choices; Elite provides the premium listed Android and memory baseline. The Vertex comparison makes those differences explicit.
Ask for the tested configuration in the quote, including required software and accessories. More memory, a camera option or a larger screen is useful only when it serves a requirement you can identify. Discuss your lesson workflow with Penthia.
