Introduction and configuration of Neets QueBec

This video explains the functions of the QueBec II & III and shows you how easy it is to configure it.

See how Neets QueBec works!

Look how easy a presentation can be started with the Neets QueBec

  • Q: How does HDMI detection work?
    A: The Neets Control - QueBec reads a HDMI signal by monitoring the “Hotplug” pin in the HDMI cable.
    “Hotplug” pin high = Image
    “Hotplug” pin low = No image
  • Q: How does VGA detection work?
    A: The Neets Control - QueBec reads the VGA signal by monitoring the H sync pin in the VGA
  • Q: Which port has the highest priority?
    A: The port detecting the latest signal is active, so in case you need to reprioritize, you want to disconnect the cable and reconnect.
  • Q: Why does the QueBec never turn off the monitor when using an HDMI extender/switch?
    A: When using an HDMI extender or a switch, the extender or switch may alter the behavior of the “Hotplug” signal.

    The problem is often that the extender / switch keeps the “Hotplug” pin high at all times. The only way to eliminate this problem is to change the order of the equipment like this:

    Q: Why does the QueBec never turn off the monitor when using an HDMI extender/switch?
  • Q: Can I use an HDMI extender/switch in combination with the Neets Control - QueBec?
    A: Yes, as long as the HDMI extender or switch lets the “hotplug” signal through, it should be possible.
    (Ask your extender/switch supplier for more information)
  • Q: The QueBec does not detect a VGA signal. What is wrong?
    A: In order to work, the QueBec needs to detect a signal on the horizontal sync pin. The easiest way to make sure this is happening is to connect your source directly to your display which you then turn on to see if you get a picture.

    If you have a long cable between your PC and the QueBec, the voltage may drop below the level detectable by the QueBec. Try to move the QueBec closer to your PC and see if this solves your problem. The QueBec does not interfere with EIED communication.
  • Q: Which versions of the Neets Control - QueBec are available?
    A: The Neets Control QueBec is available in two versions:

    QueBec II – with 1 VGA port and 1 HDMI port
    QueBec III – with 2 HDMI ports
