Board looks small on the projector
Press Full screen in your board's bottom bar, set browser zoom to 100 percent, and check the projector is not showing a small window.
Try these, in order
Step 1: Move the mouse to the bottom edge of the board and press Full screen.
Press Esc to leave it. The lesson keeps running either way. On an iPad there is no Full screen button.
On your computerStep 2: Set the browser zoom back to 100 percent. On Windows, hold Ctrl and press 0.
A zoomed-out browser makes the whole board look small.
Step 3: Check the computer's display settings. The projector should show your screen at its own resolution, not a small window in the middle.
This is a computer setting, not a Cazuz one.
