ActivConnext G-Series Colour Issues


We have had two different ActivConnect's cause the same issue in the last couple of weeks. These ActivConnect's are connected to Promethean boards. Some of the time, when you turn on the Promethean board (the ActivConnect always stays on) it will load with inverse colours (for example, the standard pink background comes out green).

However, we believe it is an issue with the ActivConnect rather then the HDMI cable because this problem can be fixed either by pulling out the HDMI cord and plugging it back in OR switching to another HDMI Source (we have a windows computer on HDMI 4) and then switching back to HDMI 2 (the ActivConnect). Also, because this issue is happening on 2 separate devices it's unlikely it's a HDMI cable fault.

Thanks for any help.

    We have 12 units installed, and this just started to happen about 2 weeks as well.
    Several units affected now.
    Symptoms are quite as you describe.
    Also notice that powering off and them on the screen will restore normal colors; then, next power off and on will make it inverse again. Almost 1 out of 2 power on will bring the inverse colors.
    It's very time consuming for teachers and a global waste of time...
