It may be necessary to adjust application settings (or, persuade the application developers to modify the 
source code). The attached article from Microsoft explains this further: 
 
"How to write High-DPI Applications" by Nick Kramer msdn.microsoft.com

Resolution Switching Utility 

 
There may still be some cases were it's better to run applications at a lower resolution for some tasks, 
and at high resolution for others. A Windows 2000/XP utility is available to enable 'on the fly' switching 
between resolutions. 
 
See 

http://www-1.ibm.com/support/docview.wss?rs=0&q=9503&uid=psg1MIGR-39635

 for details. 

 

Color Management 

 

The T221 incorporates a brightness & color calibration facility. This enables the brightness and color 
characteristic of the monitor to be preset to match certain profiles. 
 
A Windows 2000/XP utility is available which enables calibration profiles to be loaded into the T221. 
 
See 

http://www-1.ibm.com/support/docview.wss?rs=0&q=9503&uid=psg1MIGR-39635

 for details. 

 
The utility has been tested in conjunction with calibration hardware & software from GretagMacbeth and 
IMAGE Smiths. The IMAGE Smiths VeriLUM tool supports T221 calibration to DICOM requirements.
