Big thanks to the DisplayLink team for not giving up. I hope DisplayLink docks will be back to normal soon. Although you compress video data for USB and decompress on chip, have you explored this "hack" yet?

What if you trick the macOS into "display port alt-mode" and transmit video data via the extra lanes? The DisplayLink SoC may needs a reprogramming for accepting data via Display Port than USB directly. The hack in the link above perhaps also requires macOS to allow support for MST – if you want to run two extended monitors, which it never did on Intel GPUs.

The downside is that USB 3 ports will drop to USB 2.0 due to lack of bandwidth.

I'm trying to give you ideas, although I might be wrong.


There are no alternatives. DisplayLink's business model (unique selling point) is solely based on their proprietary compression technology, allowing them to squeeze a broad bandwidth video signal through a tight USB cable.

It seems Apple has fundamentally changed how frame buffers are passed on to external displays. As far as I understand the DisplayLink driver was sort of a Man-in-the-Middle hack – hijacking the frame buffers and compressing them for the USB's bandwidth bottleneck. Apparently, that trick doesn't work anymore. Now, if that's the case it does take more effort than just a few new lines of code.

We just have to be patient, stick with 10.13.3 for now, and hope everything will be fine again soon.

Has this issue been resolved for you? I am experiencing the same problem and am wondering if you've found a solution.

Display does not work
 

I am operating High Sierra 10.13 and my display is stuck in sleep mode. Have uninstalled and reinstalled the driver several times to no avail.

Please help me find a solution!

Since this is a new solution, how about some quick documentation of how to choose and set which monitor is cloned? I'm not seeing a place to make that choice right now.

MCT makes similar but inferior products. I have one (within a J5Create USB dock) but I do not recommend them. Since upgrading to High Sierra their driver has consumed high amounts of CPU and neither J5Create nor MCT seem willing to give the matter serious attention. Even when it was working prior to High Sierra it was a rather poor solution.

I have numerous DisplayLink adapters (USB2 and USB3) and they're all working very well on this 2012 11" Air (running 10.13.3) and I'm confident that DisplayLink will have this resolved as quickly as possible.

10.3.5 Beta 1 - No change
 

Didn't think it would matter, but first beta of 10.3.5 does not change the DisplayLink problem.

I did happen to find a alternative solution, Matrox DualHead2Go Digital ME works with macOS 10.13.4 its a bit more expensive than a DisplayLink adapter but it works in 10.13.4. Basically splits the display in 2. The dock and title bar end up split between the screens but it works

Thank you! Please keep the pressure on Apple.

Is there anywhere Mac users can register their annoyance / frustration to help convince Apple to fix this bug asap?

I initially bought a pair of the apple USB-C to HDMI adapters, these were absolutely junk, each time I woke my brand new power mac it would hunt for monitors, connect them, then disconnect them, connect them again and get stuck in a loop requiring me to disconnect the monitors and add them back on, one by one.

I bought a nice plugable dock to overcome Apples useless dongles making my MacBookPro usable once more.

Apples latest update has me stuck using their crappy dongles again. There was a time when Apple prided themselves on their easy of use and quality of products (especially when using their own peripherals), these days they're bloody useless.

Since not everybody has an Apple's Developer ID, the only other way I could think of is via www.change.org

Alternatively, you can also vandalize in an Apple Store to express your frustration. :D

Does anyone know if you can clone the native display while its closed in Clamshell mode? I use mine thusly, so installing beta 2 would allow me to use 2 monitors (one displayport and the 'cloned native display') effectively. however if since the native display is off, and it wont work, doesnt help me much.
