Asus Rog Strix G513 laptop monitor Black out after connecting to power supply - Refresh Rate issue

Level 7

Hello everyone,

I have a Asus ROG Strix G513 2022 (AMD R7 4800H, NVIDIA GeForce RTX 3050).  Windows 11.

It has an issue on auto change of refresh rate whenever i plug the laptop with a power adapter. The laptop monitor screen will become completely black out (not due to laptop/external monitor selection of extend/duplication issue), and I somehow cannot disable the function of auto refresh rate change. I researched online and could disable variable refresh rate from WIndows 11, AMD chipset software. Yet the problem remains.  I tried to turn off the Panel Power Save in Armoury Crate, and the screen black out immediately even if it is not connected to a power supply.

Please help!! Thank you!

Laptop screen black out when power supply is connected




Refresh Rate is changed to 144hz after power supply is connected


After unplugging power adapter, refresh rate automatically dropped to 60hz. Notebook screen returns



I disabled anything related to auto refresh rate or dispay in AMD, WIndows 11, but they cannot solve the issue.

Normally, if i don't use power supply or HDMI, Asus laptop monitor is still having images.  If i turn off Panel Power Save (the red square on the icon is gone), the laptop screen will blackout immediately.  I need to connect to an external monitor in order to keep using the laptop.

I went through a lot of posts about refresh rate in this forum, but i don't see people having similar problem like I do.


If anyone knows how to fix this, please tell me.  I want to fix this and sell it.  I feel it's inappropriate to sell a device with isseue.  Thanks!
