@item -display @var{type}

@findex -display

Select type of display to use. This option is a replacement for the

old style -sdl/-curses/... options. Valid values for @var{type} are

@table @option

@item sdl

Display video output via SDL (usually in a separate graphics

window; see the SDL documentation for other possibilities).

@item curses

Display video output via curses. For graphics device models which

support a text mode, QEMU can display this output using a

curses/ncurses interface. Nothing is displayed when the graphics

device is in graphical mode or if the graphics device does not support

a text mode. Generally only the VGA device models support text mode.
