At this station, the screen has a magnifier.
Students with impaired vision can use a magnifier to help them see details on the screen.
Because the content is bigger, the page is effectively less wide. Long lines of text have to be scrolled horizontally, which is difficult!
Press Ctrl+Alt+M to change the magnifier view mode.
Press Ctrl+Alt and click on text to have it read out.
You could also try turning the magnifier off and instead using the browser's zoom function: Ctrl+Plus.
