Manual:Administration:Resolutions

Resolutions
New in Xibo 1.0.6 and later is the ability to enter custom display resolutions directly in the Management menu.

Note that resolution is a slightly unhelpful term and this option might better be described as Aspect Ratios.

When you design a layout in Xibo, the layout is rendered for you inside an 800x600 pixel box. This ensures that it's possible for the whole layout to be seen on most computer screens. When the layout is run on a client, it is scaled back up to fit the screen its running on whilst preserving the layouts aspect ratio.

For example, a layout designed using the 16:9 Widescreen resolution we provide is actually 800x450 pixels wide. When rendered on the client, it's automatically scaled up to fit the screen. On a 1080p TV then the layout would be rendered at 1920x1080 pixels. The content is automatically scaled to take account of this. If the same layout were to be shown on a 4:3 aspect ratio monitor at resolution 1280x1024 then the client would render the layout as 1280x720 pixels, and add black bars top and bottom to compensate.

In this way, layouts in Xibo are not fixed to a particular resolution, but instead to a particular aspect ratio.

Adding New Resolutions
If you have a monitor with an aspect ratio we don't provide already, you can add a new resolution.


 * From the Management menu, select "Resolutions".
 * Click "Add Resolution" at the top of the page.
 * In the "Resolution" field, give the new resolution a name (eg 13:9 Display)
 * In the width and height boxes, input your displays resolution.
 * Click "Save"

Xibo will then automatically scale the resolution you provide to ensure it fits within an 800x600 box such that it is suitable for use in the layout designer. You can then select your new resolution from the background properties of a layout.
