DisplayLink shows off adapters and docks from HP, Lenovo, EVGA and Targus at IDF 2012

With the proliferation of Ultrabooks, laptops are shipping with fewer ports and smaller screens. One of the benficiaries of the streamlined designs is DisplayLink, whose technology can turn a single USB port into a bevy of connections. At IDF 2012, the company showed off new gear from several vendors, including EVGA, HP, Lenovo and Targus. First, there's a handsome little puck from EVGA, called the UV Plus+39, that plugs into your laptop's USB 2 or 3.0 socket to grant you HDMI and DVI output at up to 2048 x 1152 resolution for $85. Next up, Lenovo's self-explanatory USB 3.0 to DVI adapter that supports the same max resolution as the Plus+39 for $80. Lastly, a pair of docks from Targus and HP. HP's 3005pr USB 3.0 Port Replicator turns your laptop's USB 3.0 port into four USB 2.0, two USB 3.0, one HDMI, DisplayPort, and RJ-45 jacks, plus audio in and out connections for a mere $150. Targus' $250 USB 3.0 SuperSpeed Dual Video Docking Station has similar connectivity to HP's solution, but swaps DisplayPort for DVI and adds the ability to charge 90W laptops using its included array of power adapters.
