T221 installation & system attachement information
Model recommendation
The primary consideration, for choosing either the T221 model DG3 or DG5 is the rate at which it is
desired to display image changes. Internal frame buffers within the T221 ensure that the panel is always
refreshed at a suitable rate (41Hz in the DG3, 41-48Hz in the DG5); however bandwidth and I/O
considerations on the DVI interface mean that the frame buffers may be updated with new data at a
slower rate. For many applications this isn't an issue; however some applications require a higher rate so
that motion or data changes are presented as quickly and smoothly as possible.
The following table summaries the recommended T221 model and graphics card(s) depending on the
preferred update rate.

- Page 9 GUI & application optimization (Windows) The very high resolution of the T221 means that features of the graphical user interface (GUI), such as icons & fonts, become smaller. These can be adjusted through the 'display properties' window as per the following instructions.
- Page 10 The taskbar contains a start button typically in the lower left corner, with the task bar running along the bottom of the screen. To the right of the start button are a number of quick launch icons for applications. Right click anywhere in the quick launch portion of the taskbar, that is not on an icon. A pop-up menu appears.
- Page 11 It may be necessary to adjust application settings (or, persuade the application developers to modify the source code).
