6 sway-output - output configuration commands for sway
7
9 You may combine output commands into one, like so:
10 output HDMI-A-1 mode 1920x1080 pos 1920 0 bg ~/wallpaper.png
12 stretch
13 You can get a list of output names with swaymsg -t get_outputs. You may
15 also match any output by using the output name "*". Additionally, "-"
16 can be used to match the focused output by name and "--" can be used to
17 match the focused output by its identifier.
18 Some outputs may have different names when disconnecting and reconnect‐
20 ing. To identify these, the name can be substituted for a string con‐
21 sisting of the make, model and serial which you can get from swaymsg -t
22 get_outputs. Each value must be separated by one space. For example:
23 output "Some Company ABC123 0x00000000" pos 1920 0
25
27 output <name> mode|resolution|res [--custom] <WIDTHxHEIGHT>[@<RATE>Hz]
28 Configures the specified output to use the given mode. Modes are a
29 combination of width and height (in pixels) and a refresh rate that
30 your display can be configured to use. For a list of available
31 modes for each output, use swaymsg -t get_outputs.
32 To set a custom mode not listed in the list of available modes, use
34 --custom. You should probably only use this if you know what you're
35 doing.
36 Examples:
38 output HDMI-A-1 mode 1920x1080
40 output HDMI-A-1 mode 1920x1080@60Hz
42 output <name> modeline <clock> <hdisplay> <hsync_start> <hsync_end>
44 <htotal> <vdisplay> <vsync_start> <vsync_end> <vtotal> <hsync> <vsync>
45 Configures the specified output to use the given modeline. It can
46 be generated using cvt(1) and gtf(1) commands. See xorg.conf(5).
47 Only supported on DRM backend.
48 Example:
50 output HDMI-A-1 modeline 173.00 1920 2048 2248 2576 1080 1083
52 1088 1120 -hsync +vsync
53 output <name> position|pos <X> <Y>
55 Places the specified output at the specific position in the global
56 coordinate space. The cursor may only be moved between immediately
57 adjacent outputs. If scaling is active, it has to be considered
58 when positioning. For example, if the scaling factor for the left
59 output is 2, the relative position for the right output has to be
60 divided by 2. The reference point is the top left corner so if you
61 want the bottoms aligned this has to be considered as well.
62 Example:
64 output HDMI1 scale 2
66 output HDMI1 pos 0 1020 res 3200x1800
68 output eDP1 pos 1600 0 res 1920x1080
70 Note that the left x-pos of eDP1 is 1600 = 3200/2 and the bottom y-
72 pos is 1020 + (1800 / 2) = 1920 = 0 + 1920
73 output <name> scale <factor>
75 Scales the specified output by the specified scale factor. An inte‐
76 ger is recommended, but fractional values are also supported. If a
77 fractional value are specified, be warned that it is not possible
78 to faithfully represent the contents of your windows - they will be
79 rendered at the next highest integer scale factor and downscaled.
80 You may be better served by setting an integer scale factor and ad‐
81 justing the font size of your applications to taste. HiDPI isn't
82 supported with Xwayland clients (windows will blur).
83 output <name> scale_filter linear|nearest|smart
85 Indicates how to scale application buffers that are rendered at a
86 scale lower than the output's configured scale, such as lo-dpi ap‐
87 plications on hi-dpi screens. Linear is smoother and blurrier,
88 nearest (also known as nearest neighbor) is sharper and blockier.
89 Setting "smart" will apply nearest scaling when the output has an
90 integer scale factor, otherwise linear. The default is "smart".
91 output <name> subpixel rgb|bgr|vrgb|vbgr|none
93 Manually sets the subpixel hinting for the specified output. This
94 value is usually auto-detected, but some displays may misreport
95 their subpixel geometry. Using the correct subpixel hinting allows
96 for sharper text. Incorrect values will result in blurrier text.
97 When changing this via swaymsg, some applications may need to be
98 restarted to use the new value.
99 output <name> background|bg <file> <mode> [<fallback_color>]
101 Sets the wallpaper for the given output to the specified file, us‐
102 ing the given scaling mode (one of "stretch", "fill", "fit", "cen‐
103 ter", "tile"). If the specified file cannot be accessed or if the
104 image does not fill the entire output, a fallback color may be pro‐
105 vided to cover the rest of the output. fallback_color should be
106 specified as #RRGGBB. Alpha is not supported.
107 output <name> background|bg <color> solid_color
109 Sets the background of the given output to the specified color.
110 color should be specified as #RRGGBB. Alpha is not supported.
111 output <name> transform <transform> [clockwise|anticlockwise]
113 Sets the background transform to the given value. Can be one of
114 "90", "180", "270" for rotation; or "flipped", "flipped-90",
115 "flipped-180", "flipped-270" to apply a rotation and flip, or "nor‐
116 mal" to apply no transform. The rotation is performed clockwise. If
117 a single output is chosen and a rotation direction is specified
118 (clockwise or anticlockwise) then the transform is added or sub‐
119 tracted from the current transform (this cannot be used directly in
120 the configuration file).
121 output <name> disable|enable
123 Enables or disables the specified output (all outputs are enabled
124 by default).
125 output <name> toggle
127 Toggle the specified output.
128 output <name> dpms on|off|toggle
130 Enables or disables the specified output via DPMS. To turn an out‐
131 put off (ie. blank the screen but keep workspaces as-is), one can
132 set DPMS to off.
133 output <name> max_render_time off|<msec>
135 Controls when sway composites the output, as a positive number of
136 milliseconds before the next display refresh. A smaller number
137 leads to fresher composited frames and lower perceived input la‐
138 tency, but if set too low, sway may not finish compositing in time
139 for display refresh, leading to delayed frames.
140 When set to off, sway composites immediately after display refresh,
142 maximizing time available for compositing.
143 To adjust when applications are instructed to render, see max_ren‐
145 der_time in sway(5).
146 To set this up for optimal latency:
148 1. Launch some full-screen application that renders continuously,
149 like glxgears.
150 2. Start with max_render_time 1. Increment by 1 if you see frame
151 drops.
152 This setting only has an effect on Wayland and DRM backends, as
155 support for presentation timestamps and predicted output refresh
156 rate is required.
157 output <name> adaptive_sync on|off
159 Enables or disables adaptive synchronization (often referred to as
160 Variable Refresh Rate, or by the vendor-specific names FreeSync/G-
161 Sync).
162 Adaptive sync allows clients to submit frames a little too late
164 without having to wait a whole refresh period to display it on
165 screen. Enabling adaptive sync can improve latency, but can cause
166 flickering on some hardware.
167 output <name> render_bit_depth 8|10
169 Controls the color channel bit depth at which frames are rendered;
170 the default is currently 8 bits per channel.
171 Setting higher values will not have an effect if hardware and soft‐
173 ware lack support for such bit depths. Successfully increasing the
174 render bit depth will not necessarily increase the bit depth of the
175 frames sent to a display. An increased render bit depth may provide
176 smoother rendering of gradients, and screenshots which can more
177 precisely store the colors of programs which display high bit depth
178 colors.
179 Warnings: this can break screenshot/screencast programs which have
181 not been updated to work with different bit depths. This command is
182 experimental, and may be removed or changed in the future.
