NAME
       xdpyinfo - display information utility for X

SYNOPSIS
       xdpyinfo [-display displayname]

DESCRIPTION
       Xdpyinfo  is a utility for displaying information about an
       X server.  It is used to examine  the  capabilities  of  a
       server,  the predefined values for various parameters used
       in communicating between clients and the server,  and  the
       different types of screens and visuals that are available.

EXAMPLE
       The following shows a sample  produced  by  xdpyinfo  when
       connected to display that supports an 8 plane screen and a
       1 plane screen.
