Abstract

Certain applications, for example image applications, require more presentation space than can be provided by a single monitor. In addition, a single monitor may not have the required features or price/performance to provide an optimum solution.

Method for Attachment of Multiple Dissimilar Monitors

      Certain applications, for example image applications, require
more presentation space than can be provided by a single monitor.  In
addition, a single monitor may not have the required features or
price/performance to provide an optimum solution.

      Current solutions tend to be application specific, but by
contrast, this disclosure illustrates a general purpose solution that
permits the attachment of multiple dissimilar monitors.  The attached
monitors are useable by all applications running under the operating
system without modification.  This provides users with the
capability, for example, of attaching two monitors that have
dissimilar characteristics to a single workstation.

      The OS/2* operating system will be used for example purposes in
illustrating the current environment and proposed solution.
Currently, display support is designed as shown in Fig. 1.  It should
be noted that VGA and IA/A are two sample types of display for OS/2.
They are very different in terms of screen resolution and are used
for illustrative purposes only.  However, there are a wide variety of
display types on the market, each requiring separate software (a
display DLL in OS/2) to support it.

      The solution proposed in this disclosure adds a higher level
DLL (shown as "MULTIDSP.DLL" in Fig. 2 that serves three primary
purposes:
  1.  It defines a single large presentation space to the operating
       system.  The real display surfaces are mapped into th...
