Monitors wrong order on cold boot sometimes

[Ralf]

Hello. I have a multi monitor setup.

 

I had only connected the middle monitor(No.1) to the gpu when installing Windows and drivers, after gpu driver install and restart, I connected the right(No.2) monitor and after that the left(No.3) monitor.

 

Bios and Windows login is always on the middle monitor, wallpaper, icons seems to be correct. But when you launch a program or game it's on the wrong monitor because numbers got rearranged on cold boot.

It should be 3 1 2 but sometimes on cold boot it's 1 2 3 or 2 3 1, restarting the PC fixes it and goes back to 3 1 2 as it should be.

 

Right now I absolutely need to check, because if it's in wrong order, games/programs will launch on the wrong monitor and have mercy it it's the left monitor because it will mess stuff up big time.

 

Honestly I don't want to check the order on every boot I want to fix this.

 

 

The 'correct' order:

In Windows Color Management, the order is correct.

But in Nvidia Control Panel and Windows Display Settings it is not.

just rearrange the cables on the gpu to be in the config that windows is expecting it to be in , so the correct orientation goes 123 instead of 312. then whether or not it boots with the correct settings loaded it's still numbered correctly

Thanks, my issue with that is that the Bios screen won't be on the middle monitor if I do that.

No need to be passive aggressive. Cheers.
