IBM T220 (9503-DG0)
The IBM T220 was introduced in June 2001 and was the first monitor to natively support a resolution of 3840×2400. In order to support such a high resolution, it features an unusual connector arrangement. On the rear of the display are two LFH-60 connectors. A pair of cables supplied with the monitor attaches to the connectors and splits into two single-link DVI connectors each, for a total of four DVI channels. One, two or four of the connectors may be used at once.
IBM T220 comes with a Matrox G200 MMS video card and two power supplies. To achieve native resolution the screen is sectioned into four columns of 960×2400 pixels. Under DOS mode, the monitor/card combination only supports 960×1200 screen mode running at 56 Hz. The monitor's native refresh rate is 41 Hz.
