Kensington has been touting its DisplayLink Dual Monitor Adapter since before it even had a product to show off, but the company's now apparently finally gotten its act together and pushed the device out the door. Like similar devices, this one will let you add a second monitor with nothing more than a USB connection, or up to six monitors if you want to string a bunch of the adapters together. You still won't get more than a 1440 x 900 or 1280x 1024 resolution, however, but thanks to those recently released drivers, you will now be able to use it with Macs in addition to XP or Vista-based PCs. Unfortunately, as is often the case, the price has taken a bit of a jump since the company's initial estimates, with it now running $120 instead of the even $100 we were first promised.

DisplayLink's certainly no stranger to wireless monitors, but it now looks set to push the technology even further along, with it and Alereon trotting out a new reference design for a wireless USB video card (and corresponding monitor adapter). That'll apparently let you use a monitor at a distance of up to three meters, with a throughput of 120-150mbps and lossless compression ensuring that "the image users see is the same that they'd get with a wired monitor," according to Wi-Fi Planet. What's more, you should also be able to use up to six displays at the same time, "theoretically," although DisplayLink admits that gamers likely won't be satisfied. While this is just a reference design, DisplayLink says the final adapter set should run between $150 and $250 when its released in the spring, while monitors with the technology built-in will apparently demand $150 "or more" than a comparable non-wireless model (those are expected in mid-2008).
