Standalone Operation (Laptop Only)

Are you running your mainboard as a standalone device. Is standalone mode enabled in the BIOS?

• Yes
• No

Describe the bug

I have two monitors attached via displayport, the order matters. If my https://www.samsung.com/uk/support/model/LS28AG700NUXXU/ monitor is attached to the port furthest away from the motherboard, it'll power on and off constantly.

If i want a bios display, i either need to turn off this panel or switch inputs

Steps To Reproduce

Steps to reproduce the behavior:

1. 'have LS28AG700NUXXU' on port two
2. that display powers on and off repeatedly

Expected behavior

If another display is on the primary port there is no issue, if this display is there, the display powers on and off until an OS loads, where it's then fine (only an issue in the pre-OS period)

Screenshots

If applicable, add screenshots to help explain your problem.

Operating System (please complete the following information):

• OS/Distribution: [e.g. Windows 11]
• Version: [Version]
• Linux Kernel Version: uname -a

If my monitor is attached to the port closest to the motherboard, it'll power on and off constantly

The monitor will power off or the mainboard?

What does "closest to the mainboard" mean?

If i want a bios display, i either need to turn off this panel or switch inputs

This only happens in BIOS? And only when you have two displays connected?

[JohnAZoidberg]

On AMD systems the BIOS can only display on a single display, that's a limitation of the AMD reference code.
Using either one of your monitors by itself is fine?

Apologies, i didn't explain this well.
(and i messed up the order, editing the original post)

Both monitors are connected by displayport.

If the LG is connected to the 2nd port furthest from the motherboard, the LG screen (not motherboard) will reboot constantly until the OS driver loads where it'll be fine (it's like the screen gets stuck in a reboot cycle, so you'd get maybe 1 out of every 10 seconds actually displaying the bios screen, the screen is constantly losing the connection and restarting itself)

If i plug it into the other displayport connector (closest to the mobo) this doesn't happen. In any case, once an OS driver loads all screens are fine.

This only happens in BIOS? And only when you have two displays connected?

Yes, if i power off one screen, the other works fine.

If i have the LG on the second port (furthest away from mainboard PCB) with another screen connected to the other DP port it'll cycle on and off in the bios

If i plug it into the other displayport connector (closest to the mobo) this doesn't happen.

So with the two monitors swapped, everything is okay in BIOS and OS?
So you have a satisfying workaround but you are notifying us that we can take a look and try to fix the other configuration?

Well, yes.

I only discovered the workaround yesterday while confirming the details. There is an issue there.

But anyways, just close this report, i don't want to argue about it...
