You can upload and display ad slides on your digital board of any pictures or slides you've created. Google Slides and Microsoft Powerpoint are two of the most popular programs to use to set these up, but you can use any software to create your slides as long as the output is a .png, .jpg, or .gif file under 5MB in size.
If you want the slide to fill the screen, the size should conform to the 16:9 or 9:16 aspect ratio. For an HD TV this will be 1920x1080 for a horizontal board or 1080x1920 for a vertical board at minimum. If your TV supports 4K or higher, you can create slides in the corresponding pixel sizes as long as the file remains under 5MB.
To upload a slide, go to the Digital Menus tab and click the name of the board you want to edit:
Now click the Design tab and scroll to Ad Slides. You'll see a button to Add a new slide. Click there and the New slide section will appear above it:
Drag and drop or browse to upload your image, and then choose how long you want the slide to remain on screen under "Ad slide duration."
You can change the order of the ad slides at any time by using the slider icon on the far right of each slide entry to drag and drop them into place.
Hit the Save and Close button when you're done to save your changes.
