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 in regular Roon/RoonServer earlyaccess testing, you will still need to use the below instructions to switch the OS branch over to test this update.

Please also ensure you have made a recent backup of your Roon database.

Instructions on how to switch to earlyaccess RoonOS branch:

  1. Download the RoonOS instruction file from the below link and save it on your computer - do not modify the name, extension, or content of this file.
  1. Navigate to the /Data/Reinstall directory on your ROCK.
  2. Copy the instruction file that you downloaded into the Reinstall directory.
  3. Visit the RoonOS Web Administration Page and click on the “Reinstall” button.
  4. Ensure that your Web Administration Page says that you are now using RoonOS build 255
  5. Let us know if this resolves the issue on your end

Further instructions on the Reinstall functionality can be found in this article:

Hope this helps and do let us know how it goes!
