+* How to use "xrandr" to use multiple screens in i3-wm
+
+i3-windows manager is a really good program. Simple, powerful, quite handy.
+
+Sometimes you need to use multiple screens. When you are working with i3-wm there is not too much buttons or icons to push...
+
+So you can use the command line to solve the problem.
+
+** ~xrandr~ command
+
+~xrandr~ is a command line interface to RandR extension in GNU systems.
+
+From the manual:
+
+#+begin_quote
+  "used to set the size, orientation or reflection of the outputs for a screen"
+#+end_quote
+
+Running it will allow the users to visualize the state of the outputs
+
+#+begin_example sh
+  xrandr
+#+end_example
+
+Let's suppose that you have a computer and you put a second screen by HDMI port. 
+Running ~xrandr~ with the following arguments will put the output (let's call it "HDMI") to the left of the main screen of the computer ("LVDS1") and will put an automatic resolution to the new screen:
+
+#+begin_example sh
+  xrandr --output HDMI --auto --left-of LVDS1
+#+begin_example sh
+
+That's all! 
+
+You are good to use the new screen in a second workspace. Check the i3-wm userguide for more information.
