Thanks guys. I'll keep an eye on both builds.

Hi!

just bought a NUC7i3BNK myself, which test clips do you use? I'd like to verify your results...

Can you run LE at 3840x2160@60Hz? I cannot get it to work, 30Hz only. My old zotac box (nvidia) had no problems with 4k 60hz on my TV (Sony KD-65X8505).

Cheers

My test clip is actually a full movie. I'll send you some info in PM.

I can't go to 60Hz either, but even if I could I would still use 1080p as recommended here: Should I configure Kodi with 2160p (4K) or 1080p resolution (upscaling)?
xrandr shows 30Hz max as well so it's not a kodi issue at least. I might look more into it during the weekend.

PS. We should create a new thread for the new nucs. Feels like more questions will come soon.

Kodi does not support hardware decode of 10-bit HEVC yet, it is still being developed and should appear in v18 in the future. Until then it is being software decoded by ffmpeg hence the CPU usage you're seeing.

Well ok then, that was simple

Thanks, I'll mark this thread as solved somehow.

Hi!

Hardware: Intel NUC7i3BNK with i3 Baby Canyon.
Software: v7.95.2 BETA
Test video: 2160p (4k) with 10-bit HEVC and 7.1 Dolby Digital Atmos

Result: >100% CPU usage and severe lagging. Unwatchable, and even difficult to just stop the video. The hardware *should* support 10-bit HEVC.

Here's the debug log: UAHU

Any ideas?

Can most new 4K TV's do 4K@60fps these days?
Because having the Kodi GUI run at 30fps will look sluggish.
Hence, 1080p60 was favoured over 2160p30.

My TV (Samsung 55" KS9000) supports 60Hz in full resolution, but it's only possible if you have HDMI 2.0 or DP 1.2 which is still pretty rare for HTPCs. Older HDMI ports will only handle 30Hz which, as you say, feels very sluggish.

Hi!

I have a general question regarding which resolution to choose for 4k TVs. I found this thread in the official Kodi forum: Should I configure Kodi with 2160p (4K) or 1080p resolution (upscaling)?
...where the recommendation from fritsch (kodi team member) is to use 1080p in the GUI and let Kodi switch to 2160p for appropriate movies.

I also found these recommendations for Nvidia shields which runs 4k: Recommended video settings for SPMC, NVIDIA Shield TV and UHD (4K) TVs with 4K GUI · koying/SPMC Wiki · GitHub
...where the recommendation is to set the GUI to 2160p.

I trust fritsch but the nerdy part of me wonders if there's been any progress in this area, or at least different for Libreelec? It would be nice to always output the highest possible resolution.

PS. My hardware is the newest Intel NUC: Intel® NUC Kit NUC7i3BNK
