I am using an UD-3900 with DisplayLink Manager 7.7.59503.0 on a Sony laptop (VAIO Flip 15 (Intel HD + NVidia graphics) with i7-4500 - 8Go - Win 8.1 64 bits Core…
On the UD-3900 are two Dell 24" pluged and two USB2 ext. disks.
I am having a sort of Lag or latency with the mouse and displays on the 2 Dell screens, when I am not having this phenomenon on the main screen of the laptop… It is quite annoying and I really don’t understand why.
Is there an app I can use to check what’s going on and if there is a “bandwith issue” ?
