How to avoid black screen when 1) the monitor is power off 2) Windows is at the login screen?

zzzhhh

To save power, I usually power off the monitor when leave. Sometimes I also use Windows Remote Desktop to connect to the remote machine when its monitor has been powered off. It is known that when Windows Remote Desktop is launched, the screen of the remote machine is at Windows login for security protection purpose (I hope TeanViewer can learn this function). If both conditions are true and if I tried to connect the remote machine using TeanViewer, the screen would be all black. Perhaps a cause of all-black screen is that the remote screen remains the static Windows login so there is no refresh signal. So, is there any way to avoid the all-black screen when 1) the monitor is power off 2) Windows is at the login screen? Thanks.

I know that it is a fashion to criticize Microsoft products, so I can try my best to refrain from using Windows Remote Desktop, but recent experiments seem to show that the screen is all black as long as I power off the monitor (and restore as long as I turn it on). I think headless settings is common for remote machines, for, being accessed remotely, why do we have to connect a monitor, or, as in my case, why do we have to keep the monitor on if we have one? So, it is totally unreasonable to me to have a monitor powered on even if I don't need it. As a result, I ask the question again to TeamViewer engineers, what do I do to avoid all-black screen if I powered off the monitor? Also, if this question does not bother and offend TeamViewer engineers, why do you have this all-black feature at all and tolerate the persistence of this bug (in my viewpoint as a user, yes, it is a bug) all the time?
