4.3 Differences Between Multi-Screen and Xinerama Modes 69
more screens than you have video card slots, you can use DMX to combine displays
on multiple computers into a single, virtual Xinerama display.
Thin-bezel LCD screens, which have a minimal border surrounding the active LCD
area, are ideal for creating monitor arrays for use with Xinerama. They can be physically
positioned close together, and their light weight, low-power consumption, and
low-heat output make dense placement easier.
For a graphics artist who may prefer a CRT display, it may be better to use a large
flat-screen CRT for image preview and editing flanked by LCDs or smaller CRTs for
menus, tool palettes, and office productivity software such as email.
The meaning of screen becomes a bit cloudy when dealing with Xinerama.
Each monitor and video card is a called a screen in the configuration
file, but the merged image area that spans all of the monitors is
called a screen in the displayspec and the X protocol. Wherever there
might be confusion, I??™ll use the term hardware screen to denote a monitor
and video card, and the term Xinerama screen to mean the merged
image area.
