3M at an event today showed the first example of a USB 3.0-based display. The 18.5-inch LCD is powered entirely by the bus, albeit over two ports, but should have much better refresh rates for video and other visually intensive tasks through the roughly 10 times larger, 5Gbps bandwidth versus USB 2.0's 480Mbps. The panel uses just 8W of power, or about half of what a similarly sized LCD would need.
