Using gvim under Cygwin

Today I am trying to using gvim under Cygwin console but it failed:

$ which vim
/usr/bin/vim

$ which gvim
/usr/bin/gvim

$ gvim
E233: <不能開啟 X Server DISPLAY>
Press ENTER or type command to continue

From below link we know I have to install X-Server to Cygwin:

Here are how to install and enable X-Server under Cygwin:

[Installing Cygwin/X]
A listing of the Cygwin/X packages is given below; a listing of the general Cygwin packages would be beyond the scope of this document.
Cygwin/X packages are located in the X11 category.

• xorg-server (required, the Cygwin/X X Server)
• xinit (required, scripts for starting the X server: xinit, startx, startwin (and a shortcut on the Start Menu to run it), startxdmcp.bat )
• xorg-docs (optional, man pages)
• xlaunch (optional, a wizard for starting X sessions)
• You may also select any X client programs you want to use, and any fonts you would like to have available.
• You may also want to ensure that the openssh package is selected if you wish to use ssh connections to run remote X clients.
• You may also want to ensure that the inetutils or rsh packages are selected if you wish to use telnet or rsh connections to run remote X clients. (not recommended)
