Bias lighting stays on when monitor goes to sleep. Any solutions?

[chefreinhold]

Hi everyone,

I recently installed some bias lighting behind my monitor to reduce eye strain and improve contrast. It looks great and works well, but I have one issue: the bias lighting stays on even when my monitor and PC go to sleep. This is annoying because it wastes electricity and creates unnecessary light in the room.

I'm wondering if anyone has a solution for this. Is there a way to make the bias lighting turn off automatically when the monitor goes to sleep? Or do I have to manually unplug it/physically turn off the monitor every time? I'm using a USB-powered LED strip connected to one of the monitor's ports.

Any advice would be appreciated. Thanks in advance!

Don't connect the USB to the monitor, connect it to your PC.

Then go into the BIOS and turn off "always on USB" so the USB power will shut off when your PC enters sleep.

if you read the amazon reviews this is an issue mentioned by others, unless you do the above suggestion by 'Chronified' you would need to power the monitor down by the plug also and I would imagine that after the resdue of electricity is used the leds would go off.

I've got 4 monitors so I've got a powerbar connected to a smart-plug and just tell my GoogleHome to turn on/off the monitors. Smartplugs can be purchased for $10 if you want to toss automation at this problem.

Thank you for the suggestions. Both solutions sound like they would work well. It’s a pity there’s no way to control the power going to the USB ports from the monitor’s control panel. I will try the solutions suggested and see which one works best for me. Thanks again for your help!

Thanks for that last... tip! 
I just dug out a pretty chunky but just about long enough extension cord and plugged it into my PC. If it works well, I’ll order something thinner that I can cleanly route up the mounting arm.

OK. So, they are still staying on when the PC is placed in sleep mode when directly connected. I've been in the BIOS settings and can't find a setting for "USB Always On" 

 

I did enable ERP, but like I said they are still on and the PCs been in sleep for about 10 minutes. 

 

Edit: My MB is an Aorus B550.

does 'sleep mode' stop the current to usbs? have you turned the pc off rather than sleep?

 

In sleep mode you might have to change the settings in windows power options to stop the usbs

Sleep. This is my preferred way to keep my PC. 

 

Is there another power management tool that I don't see. These are my current Windows 11 settings:

Also,  I meant to add that they do turn off when I power off the PC 

[aledsav1]

ok so they trun off with power off as expected so thats one option! I always turn my pc off at the wall at night anyway nowadays to conserve as much monay as possible:)

 

try changing the usb setting in power options see what happens? I always have my pc set to high performance and then change individual settings

It's not a Windows option.

It's kinda complicated. You see, when the system is sleeping, some motherboard allows you to enable/disable high power delivery of USB ports, allowing one to charge a device that has been connected to the system before going to sleep. However, the basic power to the USB ports always remains, to allow keyboard and mouse (or USB Ethernet, and other devices) to wake up the system. If your lights only need teh basic USB power (5V <500mA) to function, then there is really nothing you do to fix this.
