Currently '-display help' only prints the available backends. Some of those backends support suboptions (e.g. '-display gtk,gl=on'). Mention that in the help output, and point the user to where they might be able to find more information about the suboptions. The new output looks like this: $ qemu-system-aarch64 -display help Available display backend types: none gtk sdl egl-headless curses spice-app dbus Some display backends support suboptions, which can be set with -display backend,option=value,option=value... For a short list of the suboptions for each display, see the top-level -help output; more detail is in the documentation.
