I don't know of any ready (portable) solutions for this, but with a bit of plumbing work, it could be possible. The building blocks I'm thinking of is Miracast and screen casting with a virtual monitor. A rough summary what would be needed is: * Introduce "virtual" monitor screen recording to org.freedestop.portal.ScreenCast (https://github.com/flatpak/xdg-desktop-portal) and the portal backend relevant to you. * Teach e.g. GNOME Network Displays (https://gitlab.gnome.org/GNOME/gnome-network-displays) how to use virtual monitor recording. * Install a "Miracast sink" app on your device (TVs often have it built in) You could probably replace the second two steps with some VNC/RDP thing, but that will not work for many types of devices where Miracast do.
