So hooking up the bedside monitor to my PC isn't going to happen.
I'm not entirely sure why, but it seems that cloning plus extending multiple monitors tends to cause high refresh rate monitors to freak out.
I wouldn't be surprised if it was a GPU problem, Nvidia has some slight issues with non matching refresh rate monitors on the wame GPU, when any animation plays on the lower refresh rate monitor the higher refresh rate monitor temporarily matches the old low refresh rate monitor until the animation ends.
It's usually not that big of a deal, but it's an Nvidia only problem, and this is why that even though the primary reason for hooking up one of my monitors to the secondary GPU failed, I'm still happy that I did that.
I like to have chats such as Discord on my left monitor, and not the breaf animations won't ever be an issue.
Interesting note though, if ypu clone non matching aspect ratio monitors one of them will just have black bars, much better then stretching in my opinion.
