How to Display Exam Time on a Projector

1. Connect and select the right input

Connect the computer to the projector or classroom display using the venue’s normal cable or approved wireless system. Select the corresponding input on the display. Confirm that the projected image is stable before configuring the exam.

If the image disappears when a cable moves, solve that connection problem first. A webpage cannot repair a loose cable or a display input that automatically switches away.

2. Decide between mirror and extend

Mirroring shows the same desktop on the computer and projector. It is straightforward, but anything opened on that desktop may also become visible to candidates. Close unrelated windows and review notification settings.

An extended desktop gives the projector its own screen area. You can move the exam’s browser window to that screen while keeping other work on the laptop. Be careful not to leave the clock on the laptop and a blank desktop on the projector.

On Windows, the display projection menu is commonly opened with Windows + P. On macOS, use Displays in System Settings. Your managed device may expose different controls; consult your institution’s IT guidance if the expected option is unavailable.

3. Launch and move the exam display

Set up the exam, verify the date and times, then select Launch Exam Display. If using an extended desktop, drag the browser window onto the projected screen before entering fullscreen.

Use the display’s Enter Fullscreen button when the browser supports it. If permission is denied or the API is unavailable, maximise the browser window using the operating system. Escape normally leaves browser fullscreen; the examination schedule stays the same.

4. Check cropping, contrast and size

Look for missing edges, stretched numerals or a picture that does not fill the intended screen area. Review the projector’s aspect-ratio and overscan settings with the venue’s AV support if necessary.

Try the light and dark appearances in the actual room lighting. Choose a clock size, then read the time from the back row and side seats. The laptop’s brightness is not evidence that the projected numerals are readable.

If the room has several screens, inspect every screen. One output may be using a different input or scaling setting even when the others look correct.

5. Test an idle period

Leave the display untouched long enough to check screen savers, automatic input switching and power saving. The website’s controls hide after a short idle period; move the pointer, use the keyboard or tap Controls to reveal them.

Enable “Keep screen awake” if supported, and check its status. Also review the computer and projector power settings. The browser cannot guarantee that venue equipment stays powered on.

6. Rehearse offline and hand over

Complete the offline preparation check on the same computer. Then verify the session details on the projected screen with the invigilator. Keep any fallback required by the institution available.

For a large room with obstructed sightlines, use the exam hall planning guide. For display choices rather than cabling, see exam display layout and contrast.
