I found that bandicam is freeze if unplug the HDMI cable when recording. If the bandiam is recording in screen mode, if I unplug the HDMI (just the computer side), then bandicam will freeze if reconnect the cable again.
We've found that Bandicam stops working when the target of the Screen Recording Mode has been lost for any reason such as a removal of the HDMI cable.
We've forwarded this issue to our development team.
