Question Stretching a game across two monitors ?

Apr 19, 2023
I'm using Windows 10 with a 12GB 3060 and two 1440 monitors.

I've seen a lot of videos of people running games in ultra widescreen format across two screens but none of the games that I have seem to have this option in the graphics settings. So presumably it's either game dependant or is set somewhere outside of the game.

Performance issues aside, how would I actually go about running a game on two screens if it doesn't natively support it. For example Cyberpunk, Horizon Zero Dawn, or Farcry 6?

Right now, I'm more interested in how you would do this than whether or not it would be a good gaming experience.
