Can I create a presentation on PowerPoint without CoPilot that will work on a 50" screen

Yes—create the presentation with PowerPoint’s built-in action buttons, run it as a full-screen kiosk slide show, and connect the 50-inch touchscreen’s touch interface to the Windows PC; Copilot is not required.

Build the interactive presentation

1. Create slides for the main menu and each section.
2. Add large touch targets:
   • Select Insert > Shapes.
   • Under Action Buttons, choose a button shape and draw it on the slide.
   • In Action Settings > Mouse Click, select Hyperlink to.
   • Choose the destination, such as Next Slide, Previous Slide, First Slide, or a specific slide.
   • Select OK.
3. Repeat this for navigation buttons such as Home, Back, and Next.
4. Test every button using Slide Show > From Current Slide. Action buttons work during the slide show, not while editing the slide.^1^

Pictures can also be made interactive: select the picture, choose Insert > Action, and assign a destination under Mouse Click.^1^

For touchscreen use, make buttons large and well separated. Avoid interactions that depend on Mouse Over, because tapping corresponds more naturally to Mouse Click.

Run it as a kiosk presentation

1. Open Slide Show > Set Up Slide Show.
2. Under Show type, select Browsed at a kiosk (full screen).
3. Start the slide show and test navigation from the first slide.

Kiosk mode displays the presentation full-screen and loops it until someone presses Esc.^2^

If some slides should advance automatically, configure their timing under Transitions, or use Slide Show > Rehearse Timings. Do not add automatic timing to slides where visitors need time to make a choice.

Connect the 50-inch touchscreen

A video connection and a touch connection are usually separate:

• Connect HDMI, DisplayPort, or USB-C video to show the presentation.
• If the display uses HDMI for video, also connect its USB cable—often labelled Touch, USB Touch, or Upstream—to the PC.
• Install the display manufacturer’s touch driver if its documentation requires one.
• In Windows, tap the screen and confirm that touch controls the pointer on the correct display.

HDMI carries the displayed picture and audio but does not, by itself, return touch input to the computer. An interactive display normally sends that input through USB, and Windows needs the appropriate driver.^3^

The laptop itself does not need to have a touchscreen; the external display supplies the touch input.

If using the laptop and touchscreen together

To keep PowerPoint editing or presenter controls on the laptop while the presentation appears on the large screen:

1. Open Start > Settings > System > Display.
2. Select Extend these displays.
3. In PowerPoint, open Slide Show and select the 50-inch display as the slide-show monitor.
4. Enable Use Presenter View only if someone will operate the laptop and needs private notes.^4^

For an unattended public installation, test the complete setup after restarting the PC: display detection, touch alignment, every action button, videos, and the return-to-home path.
