Showing Teacher Screen

Overview

Show teacher screen allows a teacher to broadcast their computer screen to one or more student computers in either Full Screen or Windowed mode. This is a great way to demonstrate a lesson or present to students directly on their screens rather than on a smart display in the front of the classroom.

Here is a brief video demonstrating the use of Show Teacher:

Showing Teacher's Screen (Full Screen Mode)

Select one or more student computer thumbnails. If none are selected, the screen will be shown to all computers.
Click the drop-down arrow to the right of the Show button.
Select the Full Screen option.

The Teacher Console will be minimized on the teacher's computer and the screen will be displayed on the selected student computers. The student computers' keyboards and mice/trackpads will be locked while the teacher's screen is being shared in full screen.

Show Screen Settings

Active Display - Select from multiple monitors. LanSchool Classic will only show the main display monitor that is selected by Windows or Mac.
Image Quality - Ability to select from a performance slider bar for speed vs. image quality.

Turtle mode will provide the highest quality image at a lower performance.
Rabbit mode will provide the lowest quality image but best performance.

Turbo Mode - See up to 800% performance increase with 6-10 frames per second depending on available bandwidth. Turbo mode will be disabled if some of the systems selected are not capable of running at this level of performance based on computational speed.

Troubleshooting Show Teacher

LanSchool currently offers two different forms of Show Teacher/Student functions, TCP and UDP. The TCP Show Teacher/Student function currently has a hard limit of 32 students.

If Show Teacher/Student function does not work with a group of students greater than 32, check the following setting:
