Video signal strength will determine how many displays may be daisy chained together. Degradation of the video signal due to distance may limit the maximum number of displays to less than 25.

You can set up tiling through the OSD menu of each display in the array. That method is described here. You can also use HP Network Sign Manager for the same purpose. See the HP Network Sign Manager User Guide for details.

On each display, enter the OSD and navigate to the Tile submenu. Set H Monitors to the number of columns in the array and V Monitors to the number of rows. Set H Position to the column number for this display, counting from left to right. Set V Position to the row number, counting from top to bottom.

Each display in the tile mode array will receive the full image, but will display only its assigned part of the image based on its H Position and V Position.

Natural Mode allows the image to retain proportionality across the array by compensating for the width of the mullion (the distance between the active display area to the active display area of the adjacent display in the array). Set Natural Mode on or off, using the same setting for every display in the array.

If Natural Mode is off, the display shows the its entire portion of its assigned position within the active viewing area. If Natural Mode is on, each display will compensate for the mullion between the displays by eliminating that portion of its assigned image which would overlap the bezel. This results in a small part of the composite picture being invisible, as though blocked by the mullions between window panes.

Choose Natural Mode on if you want the composite to be correctly proportioned and off if you want every pixel visible. The difference can be seen in the following:
