Hallo,

Sorry for my English.

Hi,

Do you recall which version of 7.3 you previously had installed?

Does the flashing stop if you disconnect the adapter?

I'm raising this internally for further investigation.

Thanks,
James

Yes. But it does not help.

No, flashing dont stop.

I stop DLManager App and after this stop flashing.
And if i set in Screen Resolution in Win8 multiple display on duplicate displays/show only on 1. After this, flashing stop and my 2. Display (connect with Display Adapter) is only black.

I also have this same issue (1 or 2 displays have black screen always) after I upgraded to 7.4M2 on a Windows 8.1 Pro installation.

Like Vladimir, if I take a screenshot, I see the desktops for the 1 (or 2) additional monitors I plug in. The actual monitors receive a signal, but the screen output is completely black. I forgot to make a note of what version was working before I upgraded... grr. It was installed definitely some time after 9/15/13.... not sure what version was current at that point in time that I downloaded.

I also have an NVIDIA card... a GT 740m, on a Toshiba Satellite P50-ABT2G22 custom-built laptop. The previous version of the software was working fine with the 327.23 drivers. I have not tried to upgrade to newer NVIDIA drivers yet...

More to come as I diagnose further. Using an HP 3005pr USB 3.0 port replicator.

Edit 1: I was able to download 7.4M0 and revert to a working setup with the same NVIDIA drivers as before. Vladimir, this download should be helpful in the meantime: Link is here: http://displaylink.com/support/sla.php?fileid=98

Edit 2: I attached my debug files from 7.4M2 in the next post (post 11) on this thread.
