The DMP-based tile matrix is recommended only for streaming video, as all DMPs
are receiving the same signal and hence remain in sync. If a video playlist is used
instead of streaming video then they may drift out of sync over time.

For best results take the bezel width into account when configring the screen
template. Do this by determing the width/height of the bezel in pixels, then add two
times the pixel count to the width, height and X,Y coordinates in the screen

video itself orcourse is less than HD as it is being stretched across the multiple
screens. One caveat with the playlist is that all screens may not advance as the
exact same time, causing the graphics to be momentarily out of sync. If perfect
synchronization is a important then it is recommended to have one item only in the

Since the graphics are playlist controlled they can be varied over time.
