If seeing is believing, then we believe in magic. That’s the only way to describe the recently unveiled IBM T220 LCD monitor, the world’s sharpest display. The 22-inch screen has a whopping resolution of 3,840 by 2,400 pixels — a typical high-end monitor, by contrast, delivers images at 1,280 by 1,024 pixels. The difference shows. When you’re reading on screen, for example, the letters are so sharp that the words jump out at you. And looking at a complex image through a magnifying glass reveals details you can’t see with the naked eye. The price is harder to miss: $15,999.
