Displaylink ceases to work in 10.13.4

[AlbanRampon]

You're welcome Peter,
On Mojave, we don't (need to) rely on AirPlay. We use the same OS documented API we were using before, with our own encoder. That means similar performance to what you would have had on 10.13.3, plus improvements brought since by the OS, our driver and our firmware changes.
Our adaptative encoder has better quality, resolution and latency than the AirPlay route. That's why we wanted to go back to it. Also, we can drive more displays.
The encoder is similar technology that used in the wireless VR adapter released by HTC, where low latency and quality are unavoidable requirements.

There are other, more fundamental, improvements planned as well. They are long term and this is too early for me to be able to disclose content at this stage.

I think it would be interesting to review your use case on the standard implementation. If you still have these impact, we should review what is taking place to make sure that is covered in the plans.
