Display MoreTheir box simply cannot output the video signal properly because of how 10th Gen Intel chips handle video connections.
Here is exactly what is happening to that user, broken down:
1. The 10th Gen Intel Display Limitation (Intel Display 9)
As noted right in the developer's documentation under known limitations, Intel 10th Gen (Comet Lake) uses an older display architecture (Display 9) that cannot natively pass native HDMI HDR10, HLG, or HDR10+ signals through this Linux display driver stack.
When the user attempts to play a Dolby Vision Profile 7 FEL file, the custom CB1 engine tries to process the base video layer and the enhancement layer. However, because the Intel NUC’s HDMI port cannot handle the required signaling handshake with their LG C2 TV under this build, the video engine crashes or fails to render entirely. The TV triggers its default "HDR" badge because it detects an HDR metadata packet, but it gets zero video frames from the NUC.
2. The Marantz Receiver Complexities
Intel NUCs of this generation are notorious for display handshaking issues when routed through an Audio/Video Receiver (AVR) like their Marantz SR7011.
- Dolby Vision on PCs requires incredibly precise "tunneling" metadata packets.
- Passing this uncertified, custom Linux Dolby Vision signal through an older HDMI 2.0 AVR (the Marantz SR7011) to a modern HDMI 2.1 TV (the LG C2) frequently breaks the video chain completely on Intel hardware.

You'll need a new box. Unless you have a different one. N100 was optimised and will handle everything except some converstions, but if all you want to do is play DV using DV source, it will play it. Ryzen 3500U is like the base to handle everything and recommended. if you looking to get a new box. Aliexpress has a sale on right not for UK and in about 7 hours for USA. check this thread
Check for used 3500U or R2544 in ebay, but I don't think you'll get as cheap as what aliexpress are selling new. happy to help out on hardware thread if I can. Dev got R2544 for 90 euros, this will be faster than any box you currently have to. also welcome.
thank you for the reply and info, dang, I thoight I had a use for this box. Thanks again
