TV Wall can be navigated by click on "TV Wall" on the top right side. Settings can be opened on the top left side with the triple lines in the purple box.

The Matrix Switch page can be used to quickly change individual inputs and outputs for video, loop, and audio. Note: Loop Output 1 and Loop Output 2 only affect the Loop 2/MAIN output. Loop 1 will always display Input 1.

NETWORK CONTROL (CONTINUED)

The TV Wall page can be used to stitch the video outputs to create video walls within a 2X2 dimension. This includes 1X2, 2X1, or 2X2. Simply click on the desired input, draw over the grid area and click save selection. The cyan highlighted boxes will indicate the area that will be used for the new stitching. Clear selection will remove all stitching already set; this will allow new stitching to be created.

Opening settings allows for the resolution to be changed or open configuration settings.

NETWORK CONTROL (CONTINUED)

The Configuration page allows for the EZW-UH4 to update its method for receiving its IP. The IP can be set as DHCP (default) or as Static.
