Question Different shade on monitor when computer is locked

[pirate_tat87]

Hello, I currently have a situation where I have three gigabyte PC monitors, 1 of the three when the computer is locked is a bit brighter as if the light on the monitor is not shutting off, however the other two monitors go pitch black. I did previously have DisplayPort to HDMI cable connected for each monitor and now I have just DisplayPort to DisplayPort, and both sets of cables are doing the same thing, if i move the cable that is from the affected monitor to another it doesn't replicate the issue. My GPU is an MSI Gaming GeForce RTX 4060 8GB GDRR6

If you're on Windows 10/11; what are you sleep settings within Power Options>Change plan settings>Change advanced power settings? Would be a good idea to see if your OS is pending an update before tackling power options.

What driver version are you on? Considering you're using the same monitors across your layout, what is the model for your Gigabyte monitors?

I'm not sure if this is what you are referring to or not?

Windows does not have any pending updates
For the GeForce Graphics driver, I am using version Game Ready Driver 576.52 (May 19th 2025)
My main screen is: GIGABYTE - GS32QC - 32"
The two other screens are identical models: Gigabyte GS27FC 27" 180 Hz Curved Gaming Monitor

A bit of an update on this,

After some troubleshooting,

My 32" monitor when its connected to my computer using a Displayport to displayport cable and it's the only monitor connected the backlight or light shuts off as normal.

When I add even one 27" monitor to the mix that's when the 32" monitor stays lit when the display is turned off?
