I don’t have an OLED yet, so I can only report what I’ve seen elsewhere on the sub. Boot to your bios and turn off USB Dual Role Device, change it to xhci, then it should work. From powered off, hold the volume + button when you power on and it should take you to the bios.
Somebody mentioned Arzopa a few months back and I was able to find one on Amazon on sale. I got the 17.3" one on sale for like $150. It’s not the best gaming monitor, but it’s not bad, and it makes a nice second display for my work laptop.
