Co takhle:
--left-of, --right-of, --above, --below, --same-as another-output
Use one of these options to position the output relative to the position of another output. This allows convenient tiling
of outputs within the screen. The position is always computed relative to the new position of the other output, so it is
not valid to say --output a --left-of b --output b --left-of a.
