Hi, let me help you.
Sure thing — you can run different apps on each monitor at the same time. Just make sure your display is set to Extended mode (not Duplicate).
When two monitors are set to Extended mode, Windows treats them as one big continuous desktop instead of mirroring the same image. That means you can open different windows or apps on each screen and work in them independently — like having a browser on one monitor and Excel on the other.
The other option, Duplicate mode, mirrors the same screen on both monitors, so you'd see the same thing on each and couldn't run separate apps side by side that way.
