I had been having lots of lockups on my UD-ULTCDL (the newer hardware revision) since the Windows 10 Anniversary Update. Basically my entire system would pause for several seconds, with no mouse/keyboard response, especially when I had Chrome open on the second monitor.
I just saw today that DisplayLink has an 8.0 M3 release of their USB Display driver, which is newer than the one on Plugable’s downloads page (8.0 M2). I just downloaded and installed it while the dock was plugged in, then rebooted and now it seems much better. Chrome still stutters on the second monitor in some cases but I’m not getting the lockups as I was before. Fingers crossed.
Not sure whether Plugable recommends/supports installing the drivers directly from DisplayLink but just wanted to get an extra data point out there, since it seems based on other posts in this forum that others may be experiencing the same issue.
