Windows 7 Update kills USB DisplayLink

[Wim]

Hi All

For users with issues using 2 monitors at the same time, are the 2 monitors the same make and model? If the monitors appear with the same serial number, it might explain this problem.

Thanks

I have two monitors, both attached and detected by Windows 7 as you can see from the device property screencaps. How do I check for the device serial number of the individual units as per your hypothesis that they are both the same?

These two DisplayLink monitors are identical units that came with my two identical Samsung SyncMaster 2263DX monitors.

Hope someone can help! Frustrating to have to main and to auxiliary displays working fine simultaneously under Windows XP and now only one of the two DisplayLink monitors working under Windows 7.

Nope. Three different monitors for me. Matt

with mac, the device is compatible( second pic), but with pc it is not( first pic) as you can see on the pics.
without usb2.0 uga, i connected the hp monitor vga socket to the laptop and then i could see the both screens.( i bought this device usb2.0, because the socket doesn't completely fit. it comes off very easy.)(third pic)
so...
i am sure that i need a new driver for windows 7 recent update.
what do you think??? when does the new version of driver is available on the website??

I really need the log files when you're in this state on the PC. Does using Windows+P recover the display settings so the laptop screen comes on?

How do you check the serial number in device manager. I have 2 identical monitors and 2 identical adapters and can't get them to both work consistently. One always randomly flashes black screen and then eventually goes black

[Wim]

They wouldn't work at all if this was the problem. If they are randomly flashing black, do you have the adapters connected to an externally powered hub? Sounds like the adapter may not always have enough USB bus power to keep working.

Yes. They are both plugged into a brand new external powered usb hub.
If that is the problem would a solution be to switch to a better usb hub.

I currently have plugable 10 port hub (using 6 ports) which is plugged into a new surge protector that has no problems with any other item connected to them.

thx for reply
