Presentation Remote Black-Screen Buttons: What to Check

A black-screen control on a presentation remote can help you hide a slide while speaking. Check what it does in your presentation application before buying it. Blanking slide content, turning off a handheld laser and switching off a projector are separate functions.

Start with the application

Microsoft’s PowerPoint shortcuts list B or the period key for a black slide, and W or the comma key for a white slide in Windows Slide Show. Pressing the shortcut again returns to the slides. Microsoft identifies the US keyboard layout and gives separate instructions for other platforms.

This is a way to change the displayed presentation state. It is not evidence that your projector has powered down. Use the equipment’s own instructions if you need to control its power.

A remote button still has a software limit

The Logitech R800 setup guide lists a black-screen function with the qualification that it works in some applications. The guide lists the laser, slide controls and timer separately.

That caveat matters when comparing a presenter for PowerPoint, a browser-based deck or another program. A button label alone does not establish identical behavior across them. These are documented functions of that model, not our test of your computer or another remote.

Before choosing a controller:

1. Check the exact remote model and the program you will present from.
2. Find whether its documentation supports the black-screen function there.
3. Try entering and leaving the blank state with your actual slide deck.
4. Check the audience display and any remote attendee view separately.

If the listing names a black-screen button without identifying supported applications, ask for that missing detail before treating it as suitable for your deck.

Choose the device for that control

The Light Tracer listing documents a handheld pointer and charging kit, not presentation black-screen controls. If blanking slides from across the room matters, look for a compatible presentation controller rather than assuming a physical laser can do it.

Our pointer-versus-remote guide separates those functions. For online or hybrid delivery, use the audience-view checklist before relying on what only the presenter can see.
