Join multiple displays into one huge display?

Help
1

Hi everyone. I have a 3440x1440 monitor. I want to add two 2560x1440s, one on each side of the main for my flight simulator. But for some reason, the simulator runs A LOT better with one high-res display than with multiple low-res ones. So, would I be able to join the three displays into one 8560x1440 one?

Thanks in advance.

KDE/Plasma has a feature called Video wall, that should do what you want, i believe. You should find it in system settings, IIRC (not at pc, so can’t check)

I tested it with two 1920x1080s, unfortunately looks like it only stretches the screen, keeping the resolution. Looks like I will need Windows only for the sim, a lot of sim-related things work only there

I will surely try when I have the side monitors, thanks
