tldr monitor firmware buggy af, don’t be surprised if you need fiber optic cables, otherwise mine has worked “fine” since firmware 1008 assuming you disable the deep sleep OSD option (I think they took that out of fw 1011, and now you literally don’t have the deep sleep option because bugs or maybe thats the neo but not the og, I forget)

those aren’t remotely hid compliant but should function via the usb3 ports instead
