Question How do I switch games between monitors

[JacobiOneKanobi]

I recently got a new 1080p along with my 3440 ultrawide, I still want to play some games on my ultrawide but I they all go straight to the 1080p and when I transfer it to the 3440, I can't change the display to 3440, any ideas?

Did you try making the ultrawide the main monitor in windows?
Are both connected to the same GPU?
Which GPU is this? (There may be a setting in the AMD/Nvidia control panel)
