 `qemu` will always default to the primary monitor to display the VM's window.
 
-Without the `--screen` option, `quickemu` will look for the size of the smallest monitor, and use a size that fits on said monitor.
-
-The `--screen` option forces `quickemu` to use the size of the given monitor to compute the size of the window.
-**It won't use that monitor to display the VM's window if it's not the primary monitor**.
-This is useful if the primary monitor if not the smallest one, and if the VM's window doesn't need to be moved around.
-
-The `--screen` option is also useful with the `--fullscreen` option, again because `qemu` will always use the primary monitor.
-In order for the fullscreen mode to work properly, the resolution of the VM's window must match the resolution of the screen.
-
-To know which screen to use, type:
+The default resolution that `quickemu` will request is 1280 x 800.
+This can be overridden by setting `width` and `height` in the VM configuration files or passing `--width` and `--height` as command line arguments, for example:
 
 ```shell
-xrandr --listmonitors | grep -v Monitors
-```
-
-The command will output something like this:
-
-``` shell
- 0: +*HDMI-0 2560/597x1440/336+1920+0  HDMI-0
- 1: +DVI-D-0 1920/527x1080/296+0+0  DVI-D-0
-```
-
-The first number is what needs to be passed to the `--screen` option.
-For example:
-
-```shell
-quickemu --vm vm.conf --screen 0
-```
-
-The above uses the 2560x1440 screen to compute the window size, which Quickemu sizes to 2048x1152.
-Without the `--screen` option, Quickemu would have used the 1920x1080 monitor, resulting in a window
-size 1664x936.
-
-The '--screenpct' is an optional integer value between 25 \<= pct \< 100 which will override system default screen sizes.
-The VM size will be `pct` of the chosen screen.
-**If `--fullscreen` is chosen screen will be fullsize instead of being scaled down by `--screenpct` value.**
