My laptop has two options: 48 Hz and 60 Hz. Is 48 Hz a substitute for 50 Hz?
That's right please select 48Hz if 50Hz is not there.

I have the same porblem
my laptop is Lenovo E420, usnig Windows 10, suddenly screen goes black once plug the power cord; while it works just fine on battery
I try to change refresh rate, but it is only 60p GHz, with no option to change it or other value.
I try to change power plan options ... without any change.
