Ugh, balenaetcher messed with my USB pen drive so that I had to jump through hoops to make it usable again. Based on web searches, this was not uncommon at that time. I haven’t had issues with ventoy so far. However, maybe I’ll just go back to Rufus.
I don’t believe that the USB-C ports can take video input, so you would most likely need to use either and HDMI to DP or USB-C to DP adapter.
