Support external DisplayLink USB displays for Presenter/Reviewer mode

Some recent music production gear supports external USB displays based on the Synaptics DisplayLink protocol, which allows you to connect an external USB display, or use a DisplayLink USB-A to DVI/HDMI adapter to connect a large screen display/TV/projector, a live video mixer, or a video capture adapter.

One prominent example is Yamaha Montage and MODX series of music synthesizers, where the embedded Linux kernel includes relevant kernel drivers for DisplayLink chipsets, so they can output the main GUI screen, in 1:1 pixel ratio, and the sub-display screens stacked below the main GUI (on the most recent Yamaha Montage M). You can see these floating GUI windows in most Yamaha Montage demos and tutorials like the one below:

It would be great if the WING would support DisplayLink USB output as well. I see the following use cases:

1) Improved Presenter/Reviewer experience for product demos/reviews/tutorials

It's much more convenient to use a dedicated video output to present the actual GUI screen, rather than set up an overhead video camera to capture that small 10" display.

Basically it's never a good idea to film a TFT screen, inevitably there will be issues with display brightness and flickering, camera shaking, fish-eye lens distortions, and presenter's hands obscuring the UI during touch-screen operation.

And filming several sub-displays is practically impossible, while dedicated video output can include them all alongside the main screen.

2) Large external touchscreen display to double as the main screen

A bigger external screen may be preferred in studio settings, for show programming, by visually impaired users, etc. The UI could adapt to the native resolution of the external display, instead of relying on image upscaling which can result in a blurry image.

Mobile 10-12” DisplayLink USB displays typically include a touchscreen which sends the touch data on the same USB connector.

Desktop 14-19" DVI/HDMI touch-capable displays come with a separate USB-A plug for the touchscreen, so a compatible USB 2.0 hub can be used to connect both the DVI/HDMI adaptor and the touchscreen cable to the USB port on the WING.

3) Task-specific dedicated UI with touch control

The WING series could use external displays as a dedicated fixed-function UI for specific tasks like realtime spectrum analyser, "wide" channel strips with additional UI elements (EQ/dynamics/buses), multitrack recorder, channel editing section, etc.

See also the related idea for an 8" ultrawide display in the Channel Dynamics section. There are external 8” and 8.8” bar-type ultrawide touchscreen displays for PC modders and gamers - with DisplayLink support in the WING, such displays could replace or supplement the default 2.4” non-touch sub-display in the channel editing section of the WING / WING BK, or extend the main display in the WING Compact and WING Rack.
