Did NOT work on intel nuc11paki5 & intel nuc11pahi5 with iris xe. Bummer!
The only thing close I've got is no adapter or the cable matterones. I've yet to try direct display port. But I'm not confident.
Got a big box of amazon returns today. fuuuuu..
Sanity This is almost certainly a driver issue with linux/intel not providing them. It works on windows.
I'm at the point whether to leave LE , don't really want to as I've been using it since openelec and I prefer it or move to kodi and finally use a sqldb to sync the dbs and thumbnails. (Home assistant and ssh does this twice daily at the moment). Or just settle with 10 bit HDR instead of using the full potential of the iris xe gpu and use 12bit. How many billions of colours do I need? But I can definitely tell the difference between 8 and 12 bit hdr.
There's load of information on this forum and others, where firmware updates have helped/or not helped as there appear to be lots of different lspcon chip versions. I gave up reading after a while.
Probably complain to intel forum as a last ditch effort but this has been round for a while...
FYI if you are determined to run linux and kodi/variant and use HD audio and intel I think I read that 13th Gen NUCs work without issue if you're prepared to sell/launch your existing batch and splash out yet again. They're only about $1kaud each.
