TURN ANY 4 TVs - UP TO 70" - INFO A MAGNIFICENT VIDEO WALL
This video wall controller is a very versatile device; they are great for use in churches, trade shows, clubs, parties, karaoke, and other applications. You can connect a video signal to it via HDMI, VGA, Composite, or even USB. The settings can be controlled via the included remote control, or through an RS232 interface.
Audio that arrives embedded in an HDMI signal is split off and routed to an 1/8" stereo jack for connection to a sound system. There is also an audio input so you can connect your own audio to go along with your VGA video. There are stereo RCA jacks for audio to input along with your composite video signal. (Please note that audio does not leave this device embedded in the HDMI output signals.)
There are numerous video display modes, as illustrated in the photos. The most popular is 2x2 which splits your input video into one large image spread across 4 displays. When you are using this mode, you can adjust the image to allow for the bezel size of the displays you are connecting.
Another useful adjustment is the ability to invert the image on any of the four outputs. This lets you turn your top two tv's upside down to get all of the images closer together. Works with cable boxes, video game boxes, DVD and Blueray players, computers, DVRs and other video playback devices. The default output mode is 1080p, though it can be reset to 720p for use with other devices.
The main menus are included in the manual. Sub-menus allow you to adjust: color temperature, aspect ratio, noise reduction, backlighting, audio EQ, on and off times, on-screen display language, bezel compensation adjustment, and on-screen display duration.
