I'm looking at Bazzite or Nobara before trying Linux on my main PC. I have three displays with different resolutions and refresh rates, including two portrait screens and a touchscreen built into the case. Can the desktop settings handle this, or would I need extra software?
How do I set up three different monitors on Linux?

Usually you can do the basics in the desktop's display settings without installing anything extra. Look for controls to arrange the screens, choose a primary display, rotate the portrait monitors, and set each resolution and refresh rate.
The arrangement is a virtual map. Move the rectangles to match where the screens sit physically, including their relative heights, so the pointer crosses between them where you expect. Check the settings rather than assuming every orientation and refresh rate was detected correctly.

KDE Plasma is a desktop environment, the interface and settings you interact with. Bazzite and Nobara are distributions, which package a wider operating system around a desktop and other software.
Wayland and X11 are different display system technologies. Plasma can run with Wayland, which is a reasonable starting point for monitors with different refresh rates and scaling needs. Some older apps run through XWayland for compatibility and may look blurry or scale oddly, especially with fractional scaling.

Try a live USB with all three monitors connected before committing to an install. Check rotation, available refresh rates, scaling, and whether the touchscreen responds where you touch it. A live session is a useful preview, though it doesn't guarantee the installed system will behave exactly the same way.

Does the touchscreen need separate checking even if the picture looks right?

Yes. Display output and touch input are separate things to test, particularly after rotating the screen. The picture working doesn't establish that touch is mapped correctly.

Connection type can matter. Ordinary display connections are a different situation from a USB display extender that needs special drivers. If a screen isn't detected, check how it's connected and what graphics hardware and drivers are in use before assuming the desktop can't handle three monitors.

Alignment can affect window movement too. If a window ends up partly offscreen when moved between displays, adjusting their positions in the layout may help.
