Yamaha Genos firmware 1.30 still has a bug that when external monitor is connected, the playing of any CDG MP3 files hangs the Genos. We have to press the power button of Genos to reboot it out of the hanging.
If we want to play CDG MP3 files, you have to disconnect the USB 2.0 display adapter from Genos first before turning on Genos. Playing CDG MP3 using the Genos built-in touch screen is fine.
Logitech Brio 4K webcam can handle close distance of the Genos screen up to a few inches away, but it requires the use of a computer (laptop or desktop). I used it in some experiments before on Genos and it worked.
Thanks,
Paul
