Hi there! Sorry for my bad english ;/. I have a problem with my Predator Helios 300 (PH317-51). My external monitor connected to my laptop flashes and turning off so often. I dont know what can I really do. I changed battery, AC charger, and CPU fan (because fan was damaged). I really tried everything and I don't know what can it be. Can someone help? Please don't write about Acer Service, because I don't have money for service.

    Hi @ n1eukki

    If you're finding that your laptop screen flicker only occurs when you've linked your PC to an external monitor, the problem could be the refresh rates. A device's refresh rate is a measurement of the number of times the screen redraws in one second
