Stoney, so your usb monitor works after you change the resolution?

Mine only has the 480x800 resolution, and can't get it to work properly so far.

Yes, it does. But before I have to reset the monitor (last point on the menu) and than pass new. Then the resolution ist at 600x800 and I have to set it to 480x800.

Hi,

I think I have the same issue as already described here:
http://www.displaylink.org/forum/showthread.php?t=62188

I uploaded a video here: http://sdrv.ms/1bRVmbj

You see the following:
0:00-0:49 PC Boot
0:49-0:53 I enter my password, but didn't hit Enter! So I am still in the logon-menu.
0:53-1:18 you see the screens flashing until all monitors are detected.
1:18-1:30 logon
1:30-1:50 I simply click on every screen, startmenu is shown and click on "Desktop" an the tiles are disappearing
1:50-2:00 I open Chrome and move it down, so it should be visible on the three screens at the bottom
2:00-2:20 I move the window, so that the titlebar is near the top of the screen. Chome flashes and stays when I release the mousbutton. This is not reproduceable with a really small window. Maybe the window has to be lager than the screen is, to make it flashing
2:20-2:28 Doing a doubleclick to maximize the window hides the window behind the emtpy startmenu-screen.
2:28-end the monitor on the Top always works.

My configuration:
Windows 8.1 Pro with MediaCenter
Graphiccard: AMD Radeon HD6800 (3 Monitors connected + TV connected, but disabled)
USB-Devices: 1x Samsung UbiSync7 (at the Top), 3x Mimo UM-720F at the bottom.
A Diagnosticfile is already attatched in the other thread.
Driver is up to date.

I think we have found the root cause of this issue. It seems to happen with screens that are less that 640 pixels wide, so if you rotate a minimon to 480x800, it is less than 640 pixels wide.

Without our software and technology on a Windows 8.1 PC we have reproduced this using a screen 480x800 pixels and the same problem can be seen.

I think this is a problem in Windows 8.1 with narrow screens, and not directly related to DisplayLink.

Hi Wim,

and what can we do know?

We're raising as a bug to Microsoft. Don't think there is anything we can do to fix it.

Wim

Thanks a lot, Wim. Please inform us, if there are any news.

Also having this problem, it started after I rotated my 7" Lilliput display 90 degrees. Please let us know when a fix is available asap.

Hi Guys,

I played around a little bit.
I also reinstalled my current display-drivers (NOT DisplayLink-Drivers!). After doing this and after restart the system, everything looks ok.

After the installation was finished but a restart is still required I was a little bit confused. The Monitor at the top (landscape) now has the problem, but left and the right monitor on the bottom were OK. The one in the middle still had the problem.
After the required restart all four monitors are ok.
I will watching this and post a new comment, if I recognize something more.

OK, next update:
After the next restart of the PC the problem is back.

So in short:
Reinstall latest driver and reboot: Everything OK
Next reboot: Everything back to the root and the portait-screens are not working
