I’m also running a NUC817BEH. Don’t have time to mess with this now as I’m at work but I would like to be able to fix this without having to re-install everything.
Can you send a picture of the HDMI output when connected to a TV or monitor when you’re able to?
Can you also give some additional details on your setup? m.2 ssd model? internal drive model? anything else attached?
…and internal ssd for high res audio files
The m.2 SSD for music storage is a Crucial MX500 1Tb 3D NAND SATA and the internal drive is a Transcend 256Gb Nvme PCie Gen 3 X4 MTE110S M.2 SSD. It will be a couple of days before I’ll have time to hook up a monitor.
