Experience realistic images like never before on the award-wining, world’s first 31.5" 8K monitor featuring Dell PremierColor.

The IBM T220 and T221 are LCD monitors that were sold between 2001 and 2005, with a native resolution of 3840×2400 pixels (WQUXGA) on a screen with a diagonal of 22.2 inches (564 mm). This works out as over 9.2 million pixels, with pixel density of 204 pixels per inch (80 dpcm, 0.1245 mm pixel pitch), much higher than contemporary computer monitors (about 100 pixels per inch) and approaching the resolution of print media. The display family was nicknamed "Big Bertha" in some trade journals. Costing around $8400 in 2003, the displays saw few buyers. Such high-resolution displays would remain niche products for nearly a decade until modern high-dpi displays such as Apple's Retina Display line saw more-widespread adoption.
