Question The monitor does not turn on if the refresh rate is greater than 60hz ?

[Onl1X1]

I have two monitors( Philips 226V - 60hz and Acer vg242yp -165hz). If I shut down the computer when my main monitor's refresh rate is above 60hz it won't turn on (shows no signal sign). If I unplug the second monitor, the main works fine doesn't have a problem with the refresh rate.
I have RX 580 8 GB if you are wondering.

So the acer won't turn on if the Hz is above 60?

Yes. I must unplug other monitor and then Acer will turn on
