Video Wall 2x2 video wall from two computers

    In our conference room, we want to set up 4 screens on the wall (in a 2x2 setup), to create a giant screen that will display video and audio.

    The source signal will be coming from a computer in the conference room, which can be located in proximity to the screens.

    We also want to allow a guest laptop (e.g. a visiting vendor) to get hooked up to the system ad-hoc, although the screens should display only one source at a time. This laptop might be located as far as 20 feet away from the screens.

    Can you recommend a solution for this scenario?

    By the screens
    Position your computer in proximity to the screens, along with a video-wall processor such as EZWall-Pro 2x2 or HD Video Wall Controller.
    These boxes accept one source signal to be sent out to four screens, creating a video wall.
    Connect the four outputs to your four screens using video cables.

    At the conference table
    Setup a 2-port HDMI video switch, such as KD-2x1CSK.
    This switch will allow you to have two inputs into your system, 1) your computer, and 2) your guest laptop guest.
    Your computer will be constantly connected to, say, port #1.
    Your guest laptop will get connected to port #2 without the need to disconnect your computer.
    When you want the guest laptop to be displayed on the video wall - simply switch to port #2.

    Connecting your computer
    Deploy an HDMI extender such as XTENDEX Low-Cost HDMI Extender via One CAT-5e/6 for sending the signal from the computer to the switch at the conference table.
    Connect the transmitter unit to the computer video output.
    Connect the receiver unit to port #1 of the switch at the conference table.
    Run a CATx cable between the transmitter and receiver units.

    Connecting to the video-wall processor
    Deploy another HDMI extender to send the signal from the switch at the conference table to the video-wall processor.
    Connect the transmitter unit to the output port of the switch at the conference table.
    Connect the receiver unit to the input port of the video-wall processor.
    Run a CATx cable between the transmitter and receiver units.

    Your setup is complete.

    Note: This solution assumes you'll be using HDMI across the board. Similar hardware that natively supports DVI can be deployed in the event you'll be using DVI at your signal sources.

    Note regarding audio: The best way to drive both video and audio would be to use HDMI output at the source (computers) and at the screens. If you need to use DVI - a simple DVI-HDMI adapter will take care of the video (as DVI and HDMI video are compatible), but audio will need to be driven separately since DVI does not support audio.
