MV-4X No Output

Issue:

No picture is displayed from the outputs of MV-4X when connecting to Input #3 or Input #4. Input #1 and Input #2 working properly.

Details:

Inputs 1 & 2 and Inputs 3 & 4 use different chipsets, therefore, the circuits and the logics are different.
This issue may happen if you use specific video sources such as the Guntermann&Drunck DP-VisionIPCon.

* When using a standard PC/Laptop you will not have an issue using any of the 4 HDMI Inputs.
