I was reading all open threads in the forum, and I can see different behaviors. In my case, I cannot use my external monitors, after upgrading my system to Catalina. Beta 3 driver is not working, and when I tried to clean cache system is getting hung after restart.

Fix the driver.

There are several monitors on the market with such resolution Dell U4919DW, Philips 499P9H, LG 49WL95C-W and Samsung CRG9. At least for Philips 499P9H I'm not able set this resolution with i-tec device on Ubuntu. https://i-tec.cz/de/produkt/u3dual4kdp-3/

macOS Mojave 10.14.5

DisplayLink do not work properly with 4K screens @ MacOS 10.14. It looks laggy, jamming, like FPS drop.
I've described issue in details here: https://displaylink.org/forum/showthread.php?t=66349

Your Plan B is just too cumbersome.

When do you expect there will be support for MacOS 10.15.1?

Ubuntu 19.04 reached end of life on 23 January 2020, however, upgrading beyond 19.04 breaks DisplayLink functionality.

2013 retina mac on 10.9.5 2.3 and 2.4 work until reboot then all external monitors go black forcing hard power down to recover from. 2.5 and 2.6 crash EVERY browser if it has a video on the page. this is really annoying and my hands are tied hopefully someone has an idea as to why

Hello

In 2016, you presented the DL-6950 Chip.
In 2019, you present DL-6910.

Is the new Chip less powerful?

Thanks a lot, kind regards,
Thomas

There should be a driver where you have an option to rotate the screen for use on both sides. The Display monitor can only go on one side for Mac and it sucks because you should be able to use rotation for how you want your screen to be.

I would like to be able to use my monitor color calibration tool [i1Profiler] to create and used custom ICC profiles for the monitors attached to the Display Link docking station.
There does not seem to be any capability to do this with the current system.

The logfiles in /var/log/displaylink currently contain hashed garbage. It would be nice if I could read them.

When using certain applications (namely, any Native Instruments product, e.g. Kontakt and Creator Tools), DisplayLink behaves strangely as reported in another issue.
I'm used to keep the lid closed in order to use the external monitor only. Under certain circumstances, reopening the lid will keep the internal monitor disabled (i.e. black screen). The only workaround for this is hard-reboot.

Lenovo is selling docking solutions for their Thinkpad laptos. These docks have DisplayLink stickers at the button but none of them is working properly with Linux! Deepin Linux (based on Debian) is massively used in China by IT professionals working with Lenovo's Thinkpad hardware. We want at least dual monitor support working with this hardware. At the moment getting this to work is just a big pain in the a**. :-(((((((((((((

You don't have to reinvent the wheel: https://github.com/AdnanHodzic/displaylink-debian

That also would make it easy for Deepin Linux to adapt the drivers. Deepin is Linux distro #1 in China! Just think: Deepin + Lenovo (Thinkpad)

usb 3.0 to hdmi on Mac OS 10.14 makes the external monitor image considerably darker. It is unusable for editing as the image is drastically compromised and does not represent the true output.

When i switch between 2 computers using the same dock, all the windows positions are lost and i have to spend time rearranging them back to where i like them (across multiple monitors). I swap pcs regularly during the day and i waste alot of time doing this. If it can retain the windows settings it would be awesome
