I just purchased and installed the USB3-HDMI-DVI to my Sager 9170 notebook and on restart after installing the DisplayLink drivers my dual screens (I’m aiming for tri-screens) flicker on/off repetitively until I disconnect the device. I’ve worked with each of my USB3 ports and have done the install using both Windows Update and the direct download on your site.
Windows 7 x64, fully updated through 12/20/12
Intel HD 4000 Graphics w/ nVidia GeForce 675MX
27" DVI monitor through “main” DVI-in on notebook
22" DVI monitor through “main” HDMI-in on notebook
3rd monitor is 22" HDMI which I’m trying to use with the device, and it never displays a signal, just the flicker loop as described above. The flickers occur about ever 2 seconds, infinitely, and the mouse cursor resets to the center of the screen each time.
