PC loses ActivPanel (APT4-75) as a sound device
We have had two 75" ActivPanles installed and every so often, at least once a week, the PC loses the screen as an audio device.
Normally a restart resolves this, however some times we are having to restart the PC with the ActivPanel disconnected.
The ActivPanels are connected via display port to HDMI connectors included with the ActivPanel
Any advice on how we can resolve this or any suggestions?
