When I was still using the stock backbox for the backglass, I connected my laptop's display port to the VIBS board with this USB C to HDMI cable. My sole HDMI port from the laptop fed the playfield display.
When I finally upgraded to the BSA Deluxe Backbox 2, I needed this USB C dual HDMI Adapter. Now I run a single HDMI out for the playfield, and the display port outputs both my backglass and DMD.
