Hi,

My problem (similar to http://www.displaylink.org/forum/showthread.php?t=1191 and http://www.displaylink.org/forum/showthread.php?t=1130 ):
The flat screen monitor plugged on the USB to DVI does not display resolutions like (the screen turns black/off): 1920x1080; 1680x1050; 1600x1200; 1440x900 but displays "lower" resolutions like: 1280x720; 1152x870;...;640x480.
Important: I used to get the screen working perfectly with the same hardware (nothing changed) one month ago. I did reinstall my laptop in the meanwhile.
The problem is that I cannot get the 1920x1080 resolution anymore. The screen of the monitor becomes black/off. Any idea why?

My configuration:
- 1 Laptop with XP home 32 bits + 2 identical flat screen monitors (max 1920x1080)
- one FS monitor is plugged on the "monitor out" VGA of the laptop and works perfect @ 1920x1080
- the other FS monitor is plugged on the "USB to DVI-19" with DVI. The device is plugged on a USB hub. The latter is plugged to the laptop.
- UGA USB 2.0 display adapter
- Displaylink Graphics 6.0.34689.0 & Displaylink Core 6.0.34621.0 software
- the USB to DVI monitor is used as extended. Main monitor is the laptop.
- All hardware was checked and is working properly. I run through http://www.displaylink.org/forum/showthread.php?t=896 and there is nothing wrong (my code is USB\VID_17E9&PID_0360)

A few points:
- identify my 3 screens with 1-2-3 makes the USB to DVI screen flatter on/off
- built-in screen autoajustment button shows: not available (the same other screen on the laptop "monitor out" works)
- when my USB to DVI screen is set at resolution 1920x1080, my situation looks exactly like:
