If your images are still small when you click on them in preview mode it’s probably because of their original upload size.
When your images are displayed in preview mode or on the screens at a live event, they will only be as large as the file you have uploaded.
The full display screen size is 1920×1080 pixels. Thus, if you want an image to fill the screen, you must insert an image that is 1920×1080 pixels.
If your image is only half the size of the maximum, (e.g. 960×540 pixels) it will fill half of the screen.
We recommend that your images are at least 600 pixels wide for a better quality viewing experience. However, don’t try to make your image any bigger than the original. This will only cause it to be blurry and hard to read. Try to find an original image that is larger.
When it comes to images, bigger is indeed better. The larger your image (photograph, table, diagram) the more detail you can show and the better quality your end result will be. See our FAQ ‘What size should my images be?’ for more information on image sizing.
