Windows jump to secondary monitor after monitor power off

Support Graphics & Display

Related to this I have the same problem. I think the cause is that system sees LG monitor disconnected when it is actually just turned off. It is not a critical problem but is really bothersome.

First, I’m going to guess you didn’t intend to specifically link to my post in that topic, right? Second, have you tried following the OP’s solution mentioned in the topics last post?

Note, if I understood it correct, he mentioned disabling an option in the monitors own OSD settings.
