I bought the UD-3900 recently thanks to its great reviews. Oddly, it works great on a 7.5-year old HP Pavilion laptop. But when I try to use it on my wife’s work computer, an HP Elitebook 850 G1 (age unknown but relatively new and in great condition), I can’t get it to work. The only time I can get the external monitor to show the picture of the laptop is when I reboot it, and then it lasts for perhaps 2 seconds and freezes. My only option at this point is to unplug, but it never works again until I reboot.
I’ve done everything I can think to do. I’ve updated the drivers. I’ve spent time on the DisplayLink forums and followed their troubleshooting guides (like this one: http://displaylink.org/forum/showthre…). I’m getting nowhere.
Any other advice or things I can do would be appreciated.
