X Configuration Option 1 - Virtual display method – Single Screen
 The Virtual display method is the easiest to setup (Note – RGS does not support Match Receiver Display
Resolution with this method)
 One screen size only per xorg.conf
 The “taskbar” will span across all displays, and when application windows are maximized they will
maximize across all displays.
 Virtual display can support LARGE virtual display limited only by frame buffer memory. Even if you use
multiple monitors it will be one “screen” stretched across all displays.
o Single client display with standard sizes like 1680x1050
o Multiple client display acting as single monitor with the “screen” stretched across all of them. Up
to 4 display with total resolution of 6720x1050.

### Set the Option "UseDisplayDevice" "none" in this section
### and specify a specific resolution in the Screen section below

### in adjusting to unusual resolutions, but it offers no capability
### for dynamic resizing and Resolution Matching.
