Connect with a Cable
The most straightforward way to connect the Photo Wall to an external display (TVs, video projectors) is via a cable, usually HDMI or VGA cable.
First, you’ll need to open the Photo Wall slideshow link on your laptop. Then connect that laptop to the external display via the cable. The display should now mirror everything you see on your laptop screen.
Pro Tip - Set the browser to full screen to hide the browser frame so it takes the entire space available on the display. It's also suggested to connect the laptop to a power adapter so the battery won't die during the event.
