Installation
It's important to use the correct graphics card BIOS & device driver level when attaching the T221
When not pre-loaded, these are available from the IBM technical support web site (see
http://www-
1.ibm.com/support/docview.wss?rs=0&q=9503&uid=psg1MIGR-39635
) or the card supplier's support site
and are summarized below

Note: The above device driver levels are the minimum required, it is generally advantageous to use the
latest level available.
Configuration
The input flexibility offered by the T221, allows it to be driven in a number of different ways. There are a
total of 4x single-link DVI inputs, however, operation from a single DVI input as a single monitor with a
single desktop is the most simple and is typical of industry standard monitor attachment. The bandwidth
of a single-link DVI channel is limited to a maximum pixel clock frequency of 165MHz, for the T221’s
3840x2400 resolution, this corresponds to an update rate of 13Hz
Note: Internal frame buffers in the T221 retime the input data and display it at a fixed 41Hz (for the DG3)
or 41-48Hz (for the DG5).
By driving more than one input, the update rate can be increased. This is summarized below.
