Hello, I have an acer monitor V226HQL

The monitor works fine but I'm having problem when shutting down PC for longer time while leaving monitor turned on (monitors goes to sleep mode in that case).

after some time say 30min. or more when I turn on PC the monitor says "NO SIGNAL". and the workaround to solve this is to turn of PC and monitor and then turn on PC and monitor in same time.
just restarting PC leaving monitor turned on (leaving it in sleep mode) doesn't work, restarting monitor while PC in on doesn't work either.

is anyone having similar problem?
