I actually really love the default wallpaper in KDE Plasma. It changes with every release. I have a friend who also uses Plasma, and before each release, we always joke that the new wallpaper is our most anticipated feature because we’re too lazy to change our wallpapers ourselves and simply wait for new releases to do it for us.

I use it just as a regular second screen - guides, videos.

If you don’t use it for anything, launchers like Cocoon will display the game logo + status bar with info like battery, time, notifications, etc. The launcher sets the brightness to minimum when you don’t use it, but the status bar is still visible this way. You can see this in action on my post photo.

Love it! I bought it at launch 🙂
