Roon ROCK UEFI Intel NUC not showing HDMI output

Hello All, I checked with the team regarding your reports, and I have some good news - we have just submitted a potential fix for this issue to the RoonOS earlyaccess testing branch. If you wish to try the release on your end and check to see if it resolves the issue, you would need to follow the procedure outlined below. Please note that this is a RoonOS (Operating System) earlyaccess release, and this differs from the regular Roon/RoonServer earlyaccess program. If you are already enrolled…

Unfortunately, if you did, then this was not intended as a fix for the Nucleus, and by installing it, you have broken your Nucleus. I’m afraid you’re going to have to wait until @support can help you.
