Lenovo T221, 9503-DG5, 9503-DG3 manual Installation, Bios, Ibm, Configuration

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

Graphics card	BIOS	Device driver (minimum level)
		Windows XP	Windows 2000	Linux
NVIDIA Quadro FX 3400	Standard	61.76	(IBM)	61.11 (NVIDIA)
NVIDIA Quadro FX 1300	Standard

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.
