How can I get the monitor resolution using the command line?

Question

I would like to find a wallpaper that best suits my resolution. How can I get the resolution just by writing commands in the command line?

Taken from this answer:

xdpyinfo | grep dimensions

Or to get just the resolution:

xdpyinfo | awk '/dimensions/{print $2}'

OR

xdpyinfo  | grep -oP 'dimensions:\s+\K\S+'

It works for a single monitor setup but with two monitors it sums both dimensions, for me my two screens return: 3520x1200 pixels – Sylvain Pineau Feb 12 '15 at 14:31

Good point. On the other hand, this is still useful if he's searching for a single wallpaper to be spanned over all monitors. – aguslr Feb 12 '15 at 14:36
Indeed you're right, +1 ;) – Sylvain Pineau Feb 12 '15 at 14:38
@aguslr What would be the point of that? Having two 2000x1000 monitors, what use would be a 4000x2000 wallpaper image? – Jos Feb 12 '15 at 15:01

@Jos, I get it this command would return 4000x1000, that is, it puts both monitors next to each other. For example, Sylvain has two monitors (1600x900 and 1920x1200) and he gets 3520x1200. – aguslr Feb 12 '15 at 15:06

@aguslr Ah yes, you are probably right. I took his "it sums both dimensions" too literally. – Jos Feb 12 '15 at 15:09
@Jos Sorry for the confusion, I can remove my first comment if needed – Sylvain Pineau Feb 12 '15 at 15:14
Does it show monitor or GPU resolution? – Roby Sottini Jun 03 '20 at 16:12

I would just use xrandr:

HDMI3 disconnected (normal left inverted right x axis y axis)
DP2 disconnected (normal left inverted right x axis y axis)
DP3 disconnected (normal left inverted right x axis y axis)
VIRTUAL1 disconnected (normal left inverted right x axis y axis)

Here I have two screens, the resolution are:

1600x900 (laptop)
1920x1200 (monitor)

To get only the resolution of your primary monitor, you can also use this python oneliner:

$ python3 -c 'from gi.repository import Gdk; screen=Gdk.Screen.get_default(); \
geo = screen.get_monitor_geometry(screen.get_primary_monitor()); \
print(geo.width, "x", geo.height)'
1920 x 1200

To get the resolution of your extanded desktop (for a multi monitor setup):

$ python3 -c 'from gi.repository import Gdk; screen=Gdk.Screen.get_default(); \
print(screen.get_width(), "x", screen.get_height())'
3520 x 1200

Just the resolution of in-use displays: xrandr | grep " connected\|\*" — Pablo Bianchi, Apr 15 '19 at 15:54

The request was for the resolution. That is given by

xdpyinfo | grep resolution

Typically, people use resolution to mean the dimensions. The DPI is not of as much concern as the dimensions are. – muru Feb 19 '15 at 04:04

On a raspberry pi without X, I was able to get the screen resolution by running:

You can also use:

 xrandr | grep ' connected'

Example of output on one of my machines:

LVDS connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm

You can get your current screen's resolution as follows:

Get the X resolution by running:

X=$(xrandr --current | grep '*' | uniq | awk '{print $1}' | cut -d 'x' -f1)

Get the Y resolution by running:

Y=$(xrandr --current | grep '*' | uniq | awk '{print $1}' | cut -d 'x' -f2)

Output the X and Y resolution by running:
```
echo "$X"x"$Y"
```

That should be possible to do like this without using awk too.

One alternate way is:

You can start by terminal your preferred website which show you your screen resolution.

firefox https://de.piliapp.com/what-is-my/screen-resolution/

You can show the webpage on your terminal too by useing https://www.brow.sh/

If you like, you can skrapping this page by terminal by include appropriate python website skrapping tools and export the output to a terminal var.

Another solution is to use xprop:

$ xprop -notype -len 16 -root _NET_DESKTOP_GEOMETRY | cut -c 25-
11520, 1080

If anyone cares, it was slightly faster on my machine than grepping xdpyinfo

Or, if you only care about width:

$ xprop -notype -len 8 -root _NET_DESKTOP_GEOMETRY | cut -c 25-
11520

Tested only on multiple displays organized via Xinerama.

If one has two connected monitors, this seems to give their sum of dimensions. – Bach Jun 22 '22 at 11:56

xprop gives me incorrect dimensions when the monitor is turned off. – deanresin Sep 25 '23 at 01:44

For what it's worth, when using multiple connected displays and/or offsets with TwinView then xdpyinfo will give you the resolution of the entire set of displays the way they are configured. If you require the resolution of a single monitor or a monitor connected to one of the display ports you need to use xrandr. However, even in that configuration xrandr can be unreliable and not show the resolution. See this example entry from my X windows config file:

Option "MetaModes" "DP-1: 1440x900 +0+0, DP-3: 1440x900 +1568+0, DP-5: 1440x900 +3136+0"

The xrandr output looks like this:

DVI-D-0 disconnected primary (normal left inverted right x axis y axis)
HDMI-0 disconnected (normal left inverted right x axis y axis)
DP-0 disconnected (normal left inverted right x axis y axis)
DP-1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 410mm x 256mm
   1440x900      59.89*+
   1280x1024     60.02
   1280x960      60.00
   1280x800      59.81
   1280x720      60.00
   1152x864      75.00
   1024x768      70.07    60.00
   800x600       75.00    60.32    56.25
   640x480       75.00    72.81    59.94
DP-2 disconnected (normal left inverted right x axis y axis)
DP-3 connected (normal left inverted right x axis y axis)
   1440x900      59.89 +  74.98
   1280x1024     60.02
   1280x960      60.00
   1280x800      59.81
   1280x720      60.00
   1152x864      75.00
   1024x768      70.07    60.00
   800x600       75.00    60.32    56.25
   640x480       75.00    72.81    59.94
DP-4 disconnected (normal left inverted right x axis y axis)
DP-5 connected 1440x900+1568+0 (normal left inverted right x axis y axis) 410mm x 256mm
   1440x900      59.89*+
   1280x1024     60.02
   1280x960      60.00
   1280x800      59.81
   1280x720      60.00
   1152x864      75.00
   1024x768      70.07    60.00
   800x600       75.00    60.32    56.25
   640x480       75.00    72.81    59.94

You can see that DP-3 isn't showing a resolution on the line that a grep for "connected" would show. So the best, most consistent, and reliable command I've found for identifying the resolution of any individual connected display is:

/usr/bin/xrandr --query|/usr/bin/grep -A 1 connected|grep -v connected

which produces this:

   1440x900      59.89*+
--
   1440x900      59.89*+  74.98
--
   1440x900      59.89*+

At that point, it's pretty trivial to pick out the different resolutions or grep for only one port.

You can also do xrandr | grep '\bconnected\b'.

You can get the monitor resulution on follow way by bash:

read x y < <(xrandr --current | grep -oP '\d+x\d+' | tr x ' ')
echo $x
echo $y
