Adds 2 full tilt external monitors to your noteboo
I recently installed this device in my Lenovo W520 notebook to replace an earlier USB 2 version. This device is based on the Displaylink 3900 chipset, which is a better way to go than the competing Magic chipset. Plusses: 1) Over USB 3.0, this device can handle 2 WUXGA (1920x1200) monitors with aplomb. I run nearly full screen i.e. 1920x1080 HD videos with no apparent lag. 2) Powered by USB 3.0 alone. No power adapter is required Negatives: 1) Installation may be tricky - My machine has NVidia Optimus, which means automated switching between NVidia Quadro 1000m discrete, and Intel HD 3000 integrated video. To get the software to install properly, and avoid BSOD etc, it is important to disable Optimus in BIOS. Then I was able to reboot, install the Displaylink driver, reboot again with Optimus enabled, and all is well. 1b) Targus tech support is well meaning but clueless. Go to the Displaylink website forum for help. 2) There is a fixed, non-removable USB 3.0 cable. I think Targus should use an industry standard removable USB 3.0 cable to connect to the host 3) There are no screw holes for the DVI adapter. That being said, DVI does plug in fairly tight and securely 4) Although Displaylink 3900 supports up to 2560x1600 resolution, Targus chose to provide no Displayport or Dual-link DVI. Therefore, you are limited to WUXGA, or perhaps a little better. Conclusion: This is a worthwhile product for notebook users looking to add 2 additional high-res external monitors.
