Connecting daisy chain displays

Multiple displays (up to 25) can be connected in a daisy chain (connect several displays together in Tile Mode) to a computer using DisplayPort IN/OUT or with the combination of RGB IN/OUT and RS-232-C IN/OUT ports on the display.

To connect displays in a daisy chain, the displays must all be connected with the same input/output source (DisplayPort IN/OUT, RS-232-C IN/OUT, or RGB IN/OUT) as shown in the figures below.

●To daisy chain displays for video, use DisplayPort IN/OUT connections or RGB IN/OUT connections.

●To daisy chain for both video and display command and control, use DisplayPort IN/OUT plus RS-232-C IN/OUT or RGB IN/OUT plus RS-232-C IN/OUT.

NOTE: The number of displays that can be connected by daisy chain to one media player/computer might vary depending on the signal status and cable loss. If the signal status is good, and there is no cable loss, it is possible to connect up to twenty-five displays in a daisy chain from one media player/ computer.

If you are going to play video that is copy protected with High-bandwidth Digital Content Protection (HDCP), a maximum of six displays can be daisy chained.

To connect multiple displays in a daisy chain, connect the input signal cable from the media player/ computer to the first display in the daisy chain. Connect the subsequent displays, using the same input signal cables, from the OUT port to the IN port of the next display, as shown in the figures below, until all the displays are connected together.
