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.
