NAME
       sway-output - output configuration commands for sway

DESCRIPTION
       You may combine output commands into one, like so:

	   output HDMI-A-1 mode	1920x1080 pos 1920 0 bg	~/wallpaper.png
	   stretch

       You can get a list of output names with swaymsg -t get_outputs. You may
       also match any output by	using the output name "*". Additionally, "-"
       can be used to match the	focused	output by name and "--"	can be used to
       match the focused output	by its identifier.

       Some outputs may	have different names when disconnecting	and reconnect-
       ing. To identify	these, the name	can be substituted for a string	con-
       sisting of the make, model and serial which you can get from swaymsg -t
       get_outputs. Each value must be separated by one	space. For example:

	   output "Some	Company	ABC123 0x00000000" pos 1920 0

COMMANDS
       output <name> mode|resolution|res [--custom] <WIDTHxHEIGHT>[@<RATE>Hz]
	   Configures the specified output to use the given mode. Modes	are a
	   combination of width	and height (in pixels) and a refresh rate that
	   your	display	can be configured to use. For a	list of	available
	   modes for each output, use swaymsg -t get_outputs.

	   To set a custom mode	not listed in the list of available modes, use
	   --custom. You should	probably only use this if you know what	you're
	   doing.

	   Examples:

	       output HDMI-A-1 mode 1920x1080

	       output HDMI-A-1 mode 1920x1080@60Hz

       output <name> position|pos <X> <Y>
	   Places the specified	output at the specific position	in the global
	   coordinate space. The cursor	may only be moved between immediately
	   adjacent outputs. If	scaling	is active, it has to be	considered
	   when	positioning. For example, if the scaling factor	for the	left
	   output is 2,	the relative position for the right output has to be
	   divided by 2. The reference point is	the top	left corner so if you
	   want	the bottoms aligned this has to	be considered as well.

	   Example:

	       output HDMI1 scale 2

	       output HDMI1 pos	0 1020 res 3200x1800

	       output eDP1 pos 1600 0 res 1920x1080

	   Note	that the left x-pos of eDP1 is 1600 = 3200/2 and the bottom y-
	   pos is 1020 + (1800 / 2) = 1920 = 0 + 1920

       output <name> scale <factor>
	   Scales the specified	output by the specified	scale factor. An inte-
	   ger is recommended, but fractional values are also supported. If a
	   fractional value are	specified, be warned that it is	not possible
	   to faithfully represent the contents	of your	windows	- they will be
	   rendered at the next	highest	integer	scale factor and downscaled.
	   You may be better served by setting an integer scale	factor and ad-
	   justing the font size of your applications to taste.	HiDPI isn't
	   supported with Xwayland clients (windows will blur).

       output <name> scale_filter linear|nearest|smart
	   Indicates how to scale application buffers that are rendered	at a
	   scale lower than the	output's configured scale, such	as lo-dpi ap-
	   plications on hi-dpi	screens. Linear	is smoother and	blurrier,
	   nearest (also known as nearest neighbor) is sharper and blockier.
	   Setting "smart" will	apply nearest scaling when the output has an
	   integer scale factor, otherwise linear. The default is "smart".

       output <name> subpixel rgb|bgr|vrgb|vbgr|none
	   Manually sets the subpixel hinting for the specified	output.	This
	   value is usually auto-detected, but some displays may misreport
	   their subpixel geometry. Using the correct subpixel hinting allows
	   for sharper text. Incorrect values will result in blurrier text.
	   When	changing this via swaymsg, some	applications may need to be
	   restarted to	use the	new value.

       output <name> background|bg <file> <mode> [<fallback_color>]
	   Sets	the wallpaper for the given output to the specified file, us-
	   ing the given scaling mode (one of "stretch", "fill", "fit",	"cen-
	   ter", "tile"). If the specified file	cannot be accessed or if the
	   image does not fill the entire output, a fallback color may be pro-
	   vided to cover the rest of the output. fallback_color should	be
	   specified as	#RRGGBB. Alpha is not supported.

       output <name> background|bg <color> solid_color
	   Sets	the background of the given output to the specified color.
	   color should	be specified as	#RRGGBB. Alpha is not supported.

       output <name> transform <transform> [clockwise|anticlockwise]
	   Sets	the background transform to the	given value. Can be one	of
	   "90", "180",	"270" for rotation; or "flipped", "flipped-90",
	   "flipped-180", "flipped-270"	to apply a rotation and	flip, or "nor-
	   mal"	to apply no transform. The rotation is performed clockwise. If
	   a single output is chosen and a rotation direction is specified
	   (clockwise or anticlockwise)	then the transform is added or sub-
	   tracted from	the current transform (this cannot be used directly in
	   the configuration file).

       output <name> disable|enable
	   Enables or disables the specified output (all outputs are enabled
	   by default).

       output <name> toggle
	   Toggle the specified	output.

       output <name> dpms on|off
	   Enables or disables the specified output via	DPMS. To turn an out-
	   put off (ie.	blank the screen but keep workspaces as-is), one can
	   set DPMS to off.

       output <name> max_render_time off|<msec>
	   Controls when sway composites the output, as	a positive number of
	   milliseconds	before the next	display	refresh. A smaller number
	   leads to fresher composited frames and lower	perceived input	la-
	   tency, but if set too low, sway may not finish compositing in time
	   for display refresh,	leading	to delayed frames.

	   When	set to off, sway composites immediately	after display refresh,
	   maximizing time available for compositing.

	   To adjust when applications are instructed to render, see max_ren-
	   der_time in sway(5).

	   To set this up for optimal latency:
	   1.	Launch some full-screen	application that renders continuously,
	       like glxgears.
	   2.	Start with max_render_time 1. Increment	by 1 if	you see	frame
	       drops.

	   This	setting	only has an effect on Wayland and DRM backends,	as
	   support for presentation timestamps and predicted output refresh
	   rate	is required.

       output <name> adaptive_sync on|off
	   Enables or disables adaptive	synchronization	(often referred	to as
	   Variable Refresh Rate, or by	the vendor-specific names FreeSync/G-
	   Sync).

	   Adaptive sync allows	clients	to submit frames a little to late
	   without having to wait a whole refresh period to display it on
	   screen. Enabling adaptive sync can improve latency, but can cause
	   flickering on some hardware.
