Hi,

I have problems with my HP USB Graphic Adapter (NL571AA) and Deltaco USB 2.0 Graphic Adapter.

The setup:
HP Elitebook 850 G1 with Intel HD 4400 + HD8750M
HP 2013 Ultraslim Dockingstation
NL571AA or Deltaco USB 2.0 Graphic Adapter
3 x 21" / 3x24" Monitors (DVI)

I have tried latest drivers from HP for the adapter but the monitor connected through USB is lagging when moving objects to that monitor.
Even video is "stuttering".

All displays runs just fine when the computer lid is opened (4 displays incl. laptop monitor)
When the lid is closed the monitor connected to the USB-adapter is lagging.

Updated BIOS.
Updated USB 3.0 Controllers to the lastest available from HP.

All drivers from 6.3 -> 7.4 gives bluescreen
Latest drivers works but gives lag. any suggestion to fix the problem?
