This is what I got from Yamaha Scandinavia about extern display on Genos.
As you may be aware, video-out connectivity is not part of the Genos specification. The built-in USB-to-host socket facilitates a “Yamaha Internal Factory Function” in order to show the screen on an external display. This requires usage of certain USB-to-video adapters using a DisplayLink chipset of DL-1x5 series (e.g. Displaylink DL-165, DL-195 or Diamond Multimedia BVU-165, BVU-195) in order for Yamaha to utilise this in presentations, and specific demos.
Availability of these adaptors varies country by country, and of course Yamaha cannot give any guarantees as to their function.
USB-to-video is not mentioned on the website, brochure, owner’s manual or any other documentation and it is not regarded as an official specification.
So from me Tommy forget all about extern display, touch display and so on.
