Update
 

Just an update.
I downgraded the displaylink version to 1.11.0 and it appears to have solved my problem.

same problem here - battling with this for months
 

Exactly the same problem here, often Display Link will report No Monitor on one or both of the external monitors. When it does the resolution is way off and unworkable.

I've tried various workarounds, with varying levels of success and reliability throughout the DisplayLink 12 releases and no less reliably in DisplayLink 13

1) Quit and restart DisplayLink
2) unplug dock from Mac and plug in again
3) unplug monitors from power and back in again

Unplugging the monitors was most reliable until version 13, now it rarely helps.

Setup is:
- Mac Pro M3
- DisplayLink Universal Dell dock D6000
- 2x Dell U2414H monitors

Just tried going back to version 1.11.0 and it was worse not better.

Hi jk1978,

Thank you for your report, and I'm sorry to hear you're experiencing this issue.

Based on debug data provided by end users, I can confirm that a series of Dell U2xxxx monitors are affected when connected via DP port. Our engineering team is currently investigating the issue, and we aim to provide a solution in the next release.

Thank you, looking forward to an update soon.

I've only had problem last week or so. But driving me crazy. Trying downgrade to 1.11.0......

Only been using for 5 minutes and it already turned off my screens and gave me a message of:

"This can happen if the hard disk space is low. Please free up some space and re-enable the screens using switches in Home tab."

I know it is not a lot, since drive is fairly full. But currently I have 8 GB available. Trying to find out what the minimum is.

There is no official information how much free space is required for macOS to prevent from such instable behaviour. Based on our tests and experience, we recommend to always keep at least 18-20 GB of free space on your startup disk.

Hope that helps,
Szymon

Szymon the last update was 29th July, any news on when we can expect another update to resolve this problem?

I am having the same problem with only the zoomed in corner of the screen showing, on multiple machines. I have updated my DisplayLink software, Mac OS, and checked for updated drivers for the hardware. I have tried all of the troubleshooting steps in this and other threads, but the problem has not changed. I have contacted support, but never got a response.

It's rather difficult to work without my external monitors, and I have been unable to use them for several weeks now. It's especially frustrating seeing how many of the support responses here in the forum are to ignore the problem or insist that it isn't happening, despite all of these reports. I'm at the end of my rope here on how to handle this.

Thank you for your patience. I was hoping to share a more definitive update by now as we had a candidate fix in testing. Unfortunately, it didn’t pass all verification checks.

Given the timing, it's getting late to catch next maintenance release, so I can't confidently promise a resolution by the end of this month. If it doesn't make it the next opportunity will be the release currently scheduled for the end of September.

I understand this is frustrating and I want to assure you the development team continues to work on resolving the issue. In the meantime, if it's an option for you I recommend connecting the monitor via HDMI, as the issue is specific to the DisplayPort interface on certain Dell monitors.

Regards,
Szymon

Thank you for the HDMI tip - my dock only has one HDMI so I will try using one monitor via HMDI and one via Display Port.
