Pimax 4K stuck in second screen mode


Hi… my Unit is stuck in extended mode. and when the pimax is on the main screen flashes every now and then.
Piplay says in the “link page” that both usb and hdmi is connected… but the options page says that it is disconnected.

is there some reg key that will change mode or can i change mode in any other way?
