Yeah me too. I experience the same exact thing. This is getting out of hand.

So, with Mojave (non-beta) less than a week away, can anyone at DisplayLink give us an indication of whether their fix is ready for this?

I'd like to upgrade, and have both monitors working properly again.

What I understood from internal testing and feedback since 30th July is that the functionality was restored, with better quality than before (clamshell, rotation...)
The main item left to address on Mojave is some 2018 model with a fix having to be validated before distribution.
Me commenting on another company's readiness/work quality is inappropriate, so won't happen. You may either contact the other party or take the feedback from other users who are using this.

Kind regards,
Alban

@Alban, thanks for the quick reply, that does sound encouraging, doubt I will be the first person to try it out though

One thing I will mention, on the AirPlayed screen I am using at the moment, when the CPU is loaded up a bit with other things it starts to become a little unworkable, mouse starts skipping across the screen, and apps are slow to update the screen. Will this be improved in the move to Mojave?

Thanks again,


Peter.

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.

I sent an email about this yesterday but I've not had much luck getting the newest v5.0 beta driver working on a Mid-2017 MacBook on the latest Mojave beta. Only getting black screens with cursor. Same experience using v4.3 beta 5/6 on the latest Mojave beta.

This is all very, very good news Alban, thanks so much for expanding on the tech involved.

To expand a little on my setup, I have :

MacBook Air Mid 2012 with an di& and 8GB -so Mojave compatible unless I am very much mistaken
2 22" 1680x1050 Samsung monitors

Dual output Targus Dock: https://www.targus.com/uk/dual-video...ion-dock120euz

I ran this with good performance before mistakenly upgrading the OS one point beyond safe.

My set up now is one monitor plugged in via the lightning port and a DVI adapter, and one plugged into the Dock with one of the Beta drivers working it via AirPlay.

If I am using Chrome on the lightning-ported monitor, viewing this page which uses WebGL, for example: https://www.raf.mod.uk/aircraft/lightning/#cloudBgd , the AirPlay monitor, where I write my code is very slow to update mouse position, typing, app updates and dialogue box changes.

Moving my mouse pointer over to the lightning-ported monitor and the mouse cursor movements and screen updates are perfectly normal. Same for the built in MacBook monitor.

I can only assume that as AirPlay is not using a graphics adapter, that it is using the main CPU quite intensively, and therefore introducing 'lag' of sorts.

This is a development machine, and can be quite hard pushed at times, but even with closing known CPU hogs down this still appears.

Hope that helps a little?

Other stuff is very encouraging and I look forward to testing and reporting once on Mojave and running two screens via DisplayLink

Thanks,


Peter

I had real problems getting this one working, it was a re-install followed by about 15 minutes of fighting to get the monitor to be used as a monitor.

Just to check, on the Airplay icon up top, is 'Use as a separate display' selected / selectable?
I think that my problem is that my MacBook is 2018 model. I came back to the Airplay version and I will wait a fix to my model.

Thanks!

So I just bought a dock with DisplayLink chip and USBC connector and i'm having the same problems as above (black screen with cursor only visible, 15" 2018 MBP).

But more important question is. When you guys release the fix, will I be able to use both DP connectors from the dock to connect 2 monitors? Some people say over the net that connection through usbc only supports one external monitor....

Is that true?

So... that means there'll never be proper support for the current OS? It's a hard sell to update to Mohave on launch from a corporate point of view and this airplay driver is pretty much unworkable.

I took my laptop home, got back to work today, plugged in and it fades each display in and out being posessed until it gives up setting airplay. The airplay screen is currently black. Yay.
