We'd still need to know which kind of device (model and manufacturer) you are trying to connect and any information about how the device is connected (adapters or hubs).

Thank you

The display is an AOC i1659FWUX

The tool output should be attached.

Carlo - I am using the very latest driver for this device, which is U224-001. The latest driver is over a year old and is 2.6. Sounds like folks with other drivers are experiencing similar issues.

I've checked the logs and the monitor is on the USB bus:

I suspect our kernel extension could be blocked by macOS, which is covered in this FAQ:

That did the trick! I didn't get the popup as part of installation, but uninstalling and reinstalling got me to where I could click the "Allow" button and enable the extension.

Thank you!!!

Default Black screen with High Sierra install

I have the latest-get mac mini, exporting to several screens at our church, and the USB 2.0 adapter outputting to a screen. I recently updated to 10.13 and updated to the latest software for the adapter.

Upon startup, all screens are dark, with no response. Once I unplug the adapter, I'm able to log in again and access everything, but plugging it back in immediately hijacks the system.

Any ideas?

I have been in contact with Tripp Lite support who say that the driver is currently only supported through 10.11. No word on when it might be addressed.

Angry 2nd External Display not working

I've just installed the 4.0 driver and did not need to perform any unblocking - no prompts, no message to allow or anything.

I've found that if i have 1 external display connected, everything works fine. The moment I attach a second external display, the system tries to go into Mirrored mode and given that it is not currently working, everything fails. Is there a workaround for this?

For a workaround, try this FAQ: http://support.displaylink.com/knowl...-mirror-issues

For the bug itself, it would be very helpful if you could raise a defect with Apple.

Cheers,

I am unable to use the displayLink (even though it is detected) in HighSierra.

I have a 13" MBP retina core i7, with 2 external displays. When I plug in the DisplayLink, I get a "No Signal" message on the display. The display shows the additional screen as an option in "Displays" and the System Report shows:

Product ID: 0x4301
Vendor ID: 0x17e9 (DisplayLink (UK) Ltd.)
Version: 32.97

I'd play with different resolutions in System Preferences->Displays to ensure a valid resolution is selected.
If this fails, please send us the logs: http://support.displaylink.com/knowl...rticles/755301

Kind regards,
Carlo
