Lenovo T221, 9503-DG5, 9503-DG3 User Manual

T221 installation & system attachement information

Model recommendation

The primary consideration, for choosing either the T221 model DG3 or DG5 is the rate at whi ch 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); ho wever 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.

Graphics cards

• IBM certified graphics cards

The above cards are only supported when purchased as part of a standard or special bid model of A Pro, M Pro or Z Pro IntelliStations. Possible differences in video BIOS and/or device drivers mean that non IBM versions of these cards may not operate with the T221 as expected

• IBM certified graphics cards (EOL)

Supported on earlier, standard M Pro or Z Pro IntelliStation models. Possible differences in video BIOS and/or device drivers mean that non IBM versions of these cards may not operate with the T221 as expected

• Other, non-IBM certified graphics cards It is possible to attach the T221 to other graphics cards, however IBM support cannot be

provided for all possible options. The suppliers of the following cards claim to support the T221; they should be contacted direct for further information

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

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.
