Before creating the multi-screen arrangement, some planning will be required. The number of screens, the orientation of the screens, the physical arrangement (how they’re mounted to the wall), the resolution of the screens and the size of the bezels, will all be required before proceeding.
NOTE: When referring to the width and height of a panel, this is the measurement of the “glass” of a panel, which is the inside measurement of the panel, not the total physical measurement, including the outside molding, referred to as the “bezel”.
Determining the Canvas Size
The first step is to decide on the name and size of the canvas, in pixels (px). All the screens will be arranged within the canvas, so make sure the canvas is large enough to accommodate all of the screens. The canvas size cannot be altered after the screen arrangement is created.
Having two screens arranged landscape; side-by-side, using a resolution of 1920x1080 (1080p), the canvas should be at least 3840 X 1080 to accommodate for horizontal resolutions of both the screens.
Having two screens arranged landscape; one on top of the other, using a resolution of 1920x1080(1080p), the canvas should be at least 1920 X 2160 to accommodate for the vertical resolution of both screens.
Knowing the resolutions of the screens is critical in determining the total canvas size.
