          3. 1920 x 1080 @ 120 kHz
          4. 1600 x 1200 @ 120 kHz
          5. 1680 x 1050 @ 120 kHz

Modes format is as following: <ordinal> <resolution> @ <refresh rate> <prefered mode>. The <ordinal> is used later to refer to the mode in other operations (for example to set the mode to a desired one).

Modes are always shown ordered from the highest resolution and referesh rate, to the lowest. This makes the ordinals stable between runs.

Position

wltile position <TARGET_OUTPUT> <RELATION> <REFERENCE_OUTPUT> [ALIGNMENT]

Arguments:
  <TARGET_OUTPUT>     Output to be positioned
  <RELATION>          How is it positioned to the reference output [possible values: left-of, right-of]
  <REFERENCE_OUTPUT>  Reference Output
  [ALIGNMENT]         Alignment [default: align-bottom] [possible values: align-bottom, align-top]

Options:
  -h, --help  Print help

Example:

$ wltile position DP-2 left-of eDP-1 align-bottom

Set

wltile set <TARGET_OUTPUT> <PROPERTY> <VALUE>

Arguments:
  <TARGET_OUTPUT>  
  <PROPERTY>       [possible values: mode, scale]
  <VALUE>
