X1 Yoga (1st Gen) - External monitor continuously goes off and on when shall be Off (power mgmt)

I have an X1 Yoga (1st gen), running Windows 10 Pro. I use an external monitor connected through the miniDVI-DVI cable in the extended desktop configuration (both monitors - internal and external are active). After the screen-off timeout - when the computer screen shall go off - the built-in monitor is switched off, but the external one is going to sleep for only a second, then it is activated for a moment - presents the message that there is no signal and goes to sleep again, but again only for a second... this is endless, and I'm afraid will soon kill my monitor ;-( Any idea how to fix this Apart from disabling the screen-off timer completely?
