Question about Screen Mirroring at different resolutions and refresh rates between Gnome and KDE

I am using (and loving) Fedora 40 as my daily driver. Currently using GNOME however, I do prefer the customization and aesthetics of KDE better.

I primarily use my computer for gaming, and my wife sometimes likes to watch the games I play. (Baldurs Gate 3 for example. She loved watching the story, but wasn't interested in playing) Anyways, I play on a 32" 1440p monitor at 165hz via DisplayPort. We also have a projector which supports either 1080p or 4k, but not 1440p, and is also limited to 60hz via HDMI. In the past, when I was using KDE (Also on a different distro, GarudaKDE I think), it basically had non-existent support for screen mirroring with different resolutions and refresh rates. Gnome does not have this problem. So I am able to play on my monitor with an HDMI cable running to our projector running a mirrored display at a different resolution and refresh rate.

Lately, Gnome is feeling a little too "clunky" for my tastes, and I have been considering switching to KDE. Does anyone know if my screen mirroring question above is possible in Fedora KDE, or if I will run into similar challenges?

Thanks in advance!
