3nStar PDL007U Monitor issue

[KatarzynaCzaja]

Hello,

Can you please tell me if you are connecting those two monitors directly to the computer or using some kind of an USB hub?
When you say that only one works at a time is it always the same one or only the one that is connected first works?

The logfiles seem to have a lot of old data which makes it more complicated to find any newly reported issues with the setup.
Please run the Installation Cleaner that will clear the DisplayLink driver and the old information. Then install the new driver one more time. This should reset the old data and create fresh files.
Recreate the problem and then gather the logfiles one more time.

Best regards,
Katarzyna
