Hello everyone,

I have some questions about this motherboard I own, the Z170M extreme4.

1) I would like to disable usb power supply when I turn off my pc. Is there an option in the BIOS or a jumper on the motherboard to prevent my devices from lighting up when I turn off my PC? I searched everywhere but I could not find it.

2) Since I installed the GPU, my BIOS and boot animation are shown in lower resolution. Is there a way to have it back in full HD?

Thank you very much for any help you can provide Big smile

On page 65 of your user manual Wink

Go into the BIOS (UEFI) -> Chipset configuration -> set Good Night LED to enabled.

The lower resolution situation is usually caused by using something other than a PC monitor as a monitor. That is, a TV, although some monitors seem to be affected in the same way.

What monitor and GPU are you using? What cable interface are you using?

Do you have the GPU's driver installed? If so, or even with a default Windows graphics driver, did you check the resolution configuration in the driver's software?

The Full HD UEFI option when set to Auto, the default, should maintain the full HD resolution in the UEFI and during startup. But that can be affected by the GPU being used, and monitor, as mentioned above.

Hello guys! Sorry for the late reply but it was a busy week at work.

I tried what you say but it is not working. The description says it will turn off keyboards/mice lights on standby or hibernate, which is not my issue. My problem is that I have a mouse with a small led light that does not turn off when I shut down (all the other leds on keyboard and mouse do). If I quickly unplug and replug the mouse, the led turns off, so I was thinking if I can toggle USB power supply. That would solve the issue.

I have a common monitor, not a TV. It's a 1440p Dell plugged through display port to a Geforce 1070. Maybe the bios dos not recognize my resolution?
